The Ultimate Guide to Chocolate Chip Cookies

Recipe By Tessa Arias
July 22nd, 2013

Have you ever wondered why chocolate chip cookies can be chewy, crisp, soft, flat, thick, cakey, greasy, bland, flavorful, moist, or crumbly? The Ultimate Guide to Chocolate Chip Cookies is here to show you WHY! (Originally published in 2013). Download my FREE COOKIE CUSTOMIZATION GUIDE HERE.

Figure out how to make your cookies chewy, soft, cakey, or crispy!! Make the cookie of your dreams :) :)

The Ultimate Guide to Chocolate Chip Cookies from
In this post I’m going to share with you how various ingredients and techniques can affect the taste, texture, and appearance of your chocolate chip cookies. This will hopefully help you understand how chocolate chip cookie recipes work so you can make the PERFECT batch every time, whatever you consider to be perfect. This information will allow you to alter or create your own chocolate chip recipe that produces cookies just the way YOU like them. You’ll be an expert on the anatomy of the chocolate chip cookie.

I used the Nestle Tollhouse Chocolate Chip Cookie recipe as my control and made little changes and variations in techniques and ingredients to show you how they affect the cookie.

I halved and adapted the original Tollhouse recipe. I kept everything the same through each recipe test, changing one key thing to see its effect and photographing the results for you. Be sure to check out my free Cookie Customization Guide to truly perfect your cookies!

Cookie Tools and Ingredients Used:

OXO Good Grips Medium Cookie Scoop
Chicago Metallic sheet pans
Silpat baking mats or unbleached parchment paper
KitchenAid 5-quart Stand Mixer
Oven thermometer
-King Arthur Unbleached All-Purpose Flour
-Fine sea salt
-Light brown sugar (except the granulated sugar recipe test)
-Large eggs
-Unsalted butter that was at a cool room temperature (except the melted butter recipe test)

Control Recipe

The Ultimate Guide to Chocolate Chip Cookies from


1 cup plus 2 tablespoons (5 ounces or 142 grams) all-purpose flour
1/2 teaspoon baking soda
1/2 teaspoon salt
1 stick (4 ounces or 114 grams) unsalted butter, at room temperature
1/4 cup plus 2 tablespoons granulated sugar
1/4 cup plus 2 tablespoons packed brown sugar
1/2 teaspoon vanilla
1 large egg
1 cup semi sweet chocolate chips


Preheat oven to 350°F. Line baking sheets with nonstick baking mats or parchment paper.

In a medium bowl combine the flour, baking soda, and salt.

In the bowl of an electric mixer beat the butter, granulated sugar, and brown sugar until creamy, about 2 minutes. Add the egg and vanilla, beating well to combine. Gradually beat in the flour mixture. Stir in the chocolate chips. Scoop 1 1/2 tablespoon-sized balls and place onto prepared baking sheets.

Bake for 9 to 11 minutes, or until golden brown. Cool for 2 minutes before removing to wire racks to cool completely.

Here is the control, an adapted version of the Nestle Tollhouse recipe. The full recipe I used to base all of the tweaks on is at the bottom of this post.

Baking Powder:

The Ultimate Guide to Chocolate Chip Cookies from
Removed baking soda from recipe and used 1/2 teaspoon baking powder. This produced results that were more cakey and puffed while baking.

Baking Powder AND Baking Soda:

The Ultimate Guide to Chocolate Chip Cookies from
Used 1/4 teaspoon baking powder and 1/4 teaspoon baking soda. This produced results that were crisp at the edges, soft in the middle, with a good amount of spread. The combination of the two leaveners produced the best results in my opinion.

MORE Flour:

The Ultimate Guide to Chocolate Chip Cookies from
Increased the flour to 2 cups (250 grams) which created a more crumbly dough and very little spread. The cookies were small yet thick and relatively undercooked (ooey and gooey) in the middle.

MELTED Butter:

The Ultimate Guide to Chocolate Chip Cookies from
I replaced the room temperature butter with melted and cooled butter. Instead of creaming the butter and sugar with an electric mixer, I simply stirred the butter and sugars together then let sit for 5 minutes, until the sugar was better absorbed by the butter. This produced flatter cookies that had a shiny, crackled top reminiscent of brownies. They were also more crisp at the edges.

All Granulated Sugar:

The Ultimate Guide to Chocolate Chip Cookies from
I used 3/4 cup granulated sugar in this recipe which produced flat, white, chewy, and slightly crunchy cookies but with little flavor. Since baking soda (called for in the control recipe) requires an acid (such as brown sugar) to react, these cookies fell very flat as you can see by the way the chocolate chips protrude.

All Brown Sugar:

The Ultimate Guide to Chocolate Chip Cookies from
I used 3/4 cup packed light brown sugar in this recipe which produced thick, brown, and soft cookies with an intense butterscotch flavor. The original control recipe uses an even ratio of granulated and brown sugars. If you prefer your cookies to be flatter, chewier, or crisper, use more granulated sugar. If you prefer your cookies to be softer and thicker and have a pronounced butterscotch flavor, use more brown sugar.

24 hour CHILLED Dough:

The Ultimate Guide to Chocolate Chip Cookies from
I used the control recipe but chilled it in the fridge for about 24 hours before shaping and baking. This produced cookies that were slightly thicker, chewier, darker, and with a better depth of butterscotch flavor. If you have time, try chilling your next cookie dough for at least 24 hours, or up to 48 hours.

    Thanks for sharing!
    My fav are in the 1st picture. Is that basic or with more flour?

      Tessa — July 22, 2013 at 7:07 am

      Those are the control recipe – I took that picture a day later though.

    Michael — July 22, 2013 at 5:24 am

    That explains why my cookies are sub-par with melted butter. I’ll have to try chilling the dough. I’ve read about that in a couple baking books. Maybe I’ll give it a shot!

    Tieghan — July 22, 2013 at 5:45 am

    Thank you for this! I have always wandered what ways are best to make cookies and I think I am more of a baking soda and baking powder girl. Those cookies look perfect!
    Such a great post!

    Crystinna — July 22, 2013 at 6:08 am

    Recently I had the dilemma of “sad” chocolate chip cookies as our chef likes to call theme when I used granulated sugar. Second round I found chilling the dough with brown sugar helped a ton and they looked awesome!

    I was wondering if you had experience baking in high altitudes? By the way hope you don’t mind if I share this post in my class 🙂

    • #
      Tessa — July 22, 2013 at 7:13 am

      I bet those cookies are awesome! I totally don’t mind – hope your class finds it helpful. I have absolutely 0 experience with high altitude baking so I’m of no help there.

    What a great experiment Tessa, I love seeing the way a small change can really impact the outcome of the recipe!

    This is great! So much great information! I have always wanted to know how certain elements effected cookies. Thank you so much!

    Chelsea — July 22, 2013 at 7:37 am

    This was so helpful!! I’ve been making a family homemade chocolate chip recipe for years and could never figure out why I couldn’t ever have two similar batches. I never accounted for the state of the butter when added would play such an integral role. Hopefully now I can make the recipe more consistent and pay better homage Grandma’s good ol’ homemade chocolate chip cookie recipe! Thanks so much!

    Such a fabulous post and resource, Tessa! I’ve been wanting to do something like this myself just for fun, but it’s always seemed like such a daunting task. What did you do with all of those cookies?? 🙂

  10. #
    Laura — July 22, 2013 at 8:52 am

    Thank you SO much for this!! I am a big food science lover and chocolate chip cookies are a special favorite so it’s like you wrote this for me!! LOL!!! 😉

    I’m a recent convert to your melted butter recipe!! I _love_ the cookies that recipe produces!! I thought that I noticed that mixing time made a difference with that recipe. I have used a stand mixer and done it by hand and the cookies made with the stand mixer, and mixed a lot longer, seemed to have a better finished product. Do you think mixing (and maybe aerating) the batter effects the final cookie?

    • #
      Tessa — July 22, 2013 at 8:58 am

      That is very possible! I read something from a Cooks Illustrated publication while doing research for this post that when using melted butter + sugar in baking, the longer the sugar has to absorb into the butter the better the flavor and texture will be because the caramelization process will begin quicker.

    LOVE this post. Such a great idea, using a control recipe that pretty much everyone, their mother, and their grandmother have made. Such a good resource 🙂 especially for those that may not know how different ingredients react with one another!

    Thank you for the visual on this! I love my cookies puffy and thick with minimal spread, so I’m going for the chilled 24 hour version.

    Dan @ Casual Kitchen — July 22, 2013 at 2:07 pm

    This post is absolutely brilliant! I loved how you ran a control, then tweaked just one variable at a time. Pure, mad-sciency genius, and for a great cause: the search for the perfect cookie. I can’t wait to share this with my readers!

    Sonia — July 22, 2013 at 2:10 pm

    What an amazing experiment, its incredible to see the difference amongst the cookies. I will definately try the tollhouse recipe with the baking powder and baking soda the next time I make these.
    Thank you for sharing.

    Gianna — July 22, 2013 at 6:07 pm

    My favorite are warm and chewy. I usually make a big batch for the week to store in the fridge. I scoop out enough for a couple of trays so they are warm and chewy when I want them.

    Averie @ Averie Cooks — July 22, 2013 at 7:22 pm

    I CAN ONLY IMAGINE!!! how many dozens and dozens of cookies you made in the process of this ‘little’ experiment, Tessa! It’s amazing what you’ve done and thank you!!!!

    I love posts like this and comparisons and could take cookie science forever. I am loving this post, so much.

    For me, I am in love with adding 2 tsp of cornstach to my dough b/c it creates softbatch-style cookies, minus any cakiness. I have also tried many of the popular recipes out there for cookies, i.e NYTimes and many others and keep coming back to the cornstarch trick. I have about 10 versions and recreations with various add-ins on my site.

    Pinned to group boards! Thank you for this post!

    • #
      Tessa — July 22, 2013 at 7:44 pm

      Thanks Averie!! I think I’m going to do a part II post and include a test on that cornstarch trick because I’ve seen it in your recipes and also on Sally’s Baking Blog. Thanks for the tip!

      • #
        Judy Torck — July 28, 2019 at 2:20 pm

        I’m going to try the half baking soda and half baking powder. I like mine a little thick, chewy and crispy around the edges

    Susan at Savvy Single Suppers — July 22, 2013 at 7:30 pm

    Tessa thanks to you for taking on this experiment. I pity the poor taste testers in your life 😉 . Ive been hunting for the perfect chocolate chip cookie and this should help me. I’m going to try the soda + powder, a titch more brown than white sugar and chill for 24 hours. In my family one recipe calls for using vegetable shortening rather than butter. Have you tried this substitution before?

    • #
      Tessa — July 22, 2013 at 7:49 pm

      I am not a fan of shortening so I may be a little biased but in my experience I think butter is the better choice for a few reasons:

      1. Butter has a lower melting point (right around body temperature) than shortening which is why things with lots of butter seem to “melt in your mouth” whereas shortening can often leave a filmy residue on the tongue.
      2. Butter offers better flavor.
      3. Because butter has a high moisture content, it provides moisture to the cookies and encourages spread (which can be good or bad depending on your preferences). Cookies made with shortening tend to be drier/crumblier and thicker.

    christina — July 22, 2013 at 8:26 pm

    THIS IS AWESOME!! I’m a huge fan of chocolate chip cookies and have tried so many variations. I feel like I was nodding the whole time reading this because I’ve been there, done that with all of this!!! 🙂 Thank you!

    Debbie — July 23, 2013 at 8:52 am

    This is so great! I am on a quest for the perfect chocolate chip cookie, and will be experimenting very soon! I was wondering what are your thoughts about the amount of eggs? It didn’t seen like you tested that and I was wondering what an extra egg would do… Guess I’ll have to see! Lol

  23. #
    Megan — July 23, 2013 at 9:56 am

    I loved this … I rarely follow a recipe and this explains so much. I have one chocolate chip recipe that always worked well for me, even with substituting whole wheat flour and using honey rather than white sugar. But the “family’s” favorite has always been the Toll House Recipe that Grams used. Grams always followed the recipe … 😉

  24. #
    Desiree — July 25, 2013 at 4:19 am

    just curious– which one do you think tasted best?

    • #
      Tessa — July 25, 2013 at 8:11 am

      The funny thing is that there were little things I liked and didn’t like about each batch. I think the best *taste* goes to the 24-hour chilled dough but I also liked the butterscotch flavor of the brown sugar cookies.

  25. #
    Dave — July 25, 2013 at 6:13 am

    Yes, I’m with Desiree – which one was best?

  26. #
    Brian C. — July 25, 2013 at 10:20 am

    I find it hard to believe that someone who is so serious about their cookie tests, measures their flour by volume (instead of by weight).

    • #
      Tessa — July 25, 2013 at 10:42 am

      Hi Brian – when I bake at home I usually measure by weight but most of my readers don’t own a kitchen scale and aren’t familiar with baking by weight. I write the recipes on this blog for my readers and try to make them as simple as possible.

  27. #
    Brian C. — July 25, 2013 at 10:47 am

    So were all of your tests measured by weight, then just translated to volume for recipe purposes?

    • #
      Tessa — July 25, 2013 at 11:07 am

      That’s correct. Additionally, the original Nestle recipe is written by volume and that was my control. However, you bring up a good point. Since this is somewhat of a serious baking test I went ahead and edited the post to include weight measurements of the flour as well as the original volume. Thanks for your comment!

  28. #
    D KALE — July 25, 2013 at 1:20 pm

    you should try adding 1 tsp corn starch to a batch. Helps them to be thicker and stay soft.

  29. #
    Gayle — July 25, 2013 at 2:04 pm

    Have you tried 1/2 shortening and 1/2 butter? Crispy on the outer edges…soft inside,

    Sarah @ Sweet Miles — July 25, 2013 at 2:19 pm

    Genius!! I’ve always wondered why my cookies seem to turn out differently every time!! Bookmarking this now to refer back to it next I’m in the baking mood 🙂

      Thanks for catching that!

  32. #
    Wilma A — July 25, 2013 at 2:53 pm

    When I was growing up we didn’t use butter for baking, it was too expensive. We used Crisco shortening. What affect might that have had? Always used both brown and white sugar. Cookies were always good and didn’t spread out.

  33. #
    Debbie C — July 26, 2013 at 4:52 am

    Love the tests you conducted. I use half butter shortening and half unsalted butter plus 1 tbsp water. I also scoop my cookie balls and freeze on cookie trays, then store them in baggies so I can bake as many or little as I want at anytime. The cookies turn out fantastic!

  34. #
    Emily — July 26, 2013 at 7:47 am

    I’m supposed to be cleaning and packing for a family trip, but now I want to stop and make a batch of cookies instead. We can always take them on the plane, right? Thanks for this interesting experiment! It explains so many of my cookie “failures.” Oh, and the one with extra flour looks super yummy to me.

  35. #
    Heather — July 26, 2013 at 10:38 am

    Have you tried the NY Times Best Chocolate Cookie recipe? It uses both kinds of sugar and 2 types of flower. Also, calls for 24-72 hour chilling period. They. Are. INCREDIBLE!

    • #
      Tessa — July 27, 2013 at 8:32 am

      I’ve always wondered how using cake flour AND bread flour affects the cookies – they seem to cancel each other out in my mind if that makes sense. Will definitely be trying out different flours for part II 🙂

  36. #
    Heather — July 26, 2013 at 10:39 am

    Whoops ^^ FLOUR! lol

  37. #
    Michelle Crowder — July 26, 2013 at 3:15 pm

    Hmmm…wonder how they would be with both baking powder and soda, more brown sugar than granulated, and chilling it for 24-48 hours?????? GOTTA TRY!!!!!

  38. #
    ruth — July 27, 2013 at 2:37 am

    this is a great post – thanks for sharing! i use three different kinds of flour in my cookies (always king arthur brand – it’s the best) AP, bread and cake. this gives me a chewy, thick cookie with a good bite. would be curious to see your tests varying the flour. (also kosher salt and more brown sugar than white)

    • #
      Tessa — July 27, 2013 at 8:31 am

      Interesting! I plan on including tests with different flours on part II – thanks for your comment!

    Great idea! New to your site via Casual Kitchen who I will be forever indebted to for directing us to this. I’m already known for my cookie baking but one of my goals this year is to come up with the Ultimate Chocolate Chip cookie recipe – these tips will help me tremendously!

  40. #
    knitbunnie — July 27, 2013 at 10:40 am

    Have you ever added malted barley powder (not barley flour and not diastatic powder) to your cookies? It’s a fine, brown, barley sweetener that’s used in a lot of commercial baking. In the standard Nestle recipe, I sub in a 1/4 cup of it for 1/4 cup of the brown sugar. It really adds something subtle and good and keeps the cookies moist but not in an under-baked sort of way. If you’re up for more chocolate chip cookie experiments, it could be worth a try.

  41. #
    Lola — July 27, 2013 at 12:28 pm

    Well done, Tessa! As a social scientist, I LOVED how methodical you were with this study. I can’t wait to see what you explore with “part II.” Thanks also to therovingstove (Julianne Rhodes) for linking me to your page. 😉

  42. #
    Ashley Kaestle — July 27, 2013 at 1:07 pm

    Hi Tessa!
    Fantastic info! Just wondering what the effect of combining some of the adjustments would be? I love crisp edge, chewy centered cookies so I was thinking the baking powder/baking soda + the melted butter might be my best bet. Does it work that way though?

  43. #
    natalie — July 27, 2013 at 3:21 pm

    I love experimenting too. I have to say that using butter in Utah dries out my cookies faster. I find the soft batch style comes out much better using imperial magarine. I also lower my oven to 340 which has not made them spread. I cant wait to try half bs and bp. I also like the monster cookie variation of using ground oats, when taken out at 9 min, they produce hearty, moist cookies. I get the most compliments when I use the tollhouse recipe and pudding mix. Best cookie recipe by far. I can’t wait to see your next test, I loved all ur insight and tips! 🙂

  44. #
    Heidi — July 27, 2013 at 6:17 pm

    I assume you meant 2 large eggs in the instructions since that is what toll house uses? The directions say add one at a time … making some right now with 2 eggs and 1/2 soda 1/2 powder.. tempted to add some cornstarch too.

    • #
      Tessa — July 27, 2013 at 6:46 pm

      Just one egg! I forgot to edit the instructions – thanks for pointing this out!

  45. #
    Heidi — July 27, 2013 at 6:21 pm

    now I see the recipe is halved so just 1 egg , I just got confused with the add one at a time…

    Came across this post via Pinterest and wanted to leave a note to say how much I appreciate it! I’m not a baker (or rather, I’m a beginner baker) so all the variations in cookie recipes can be overwhelming. This was very helpful in explaining what variations can do and which would be most appealing to me.

    Doreen Briese — July 29, 2013 at 11:08 am

    Love this comparison! I have always added the extra flour, something I started years ago because the batter just seemed too thin, and left the mix in the refrig for 24 hours before baking (mix one night, bake the next due to work!). Always got compliments on my cookies. But now I want to try the 1/4 baking soda and 1/4 baking powder and also maybe experiment with a little more brown sugar to see how they turn out, Thank you!!

    You didn’t say when to add the vanilla.My cookies turn out puffy when I take them out of the oven but then when they cool they go flat.So I am going to try adding the baking soda,baking powder and cornstarch and use more brown sugar and less granulated sugar.Then chill for at least 24 hours.Thanks for all the test you did.Appreciate it.

  52. #
    Noell — July 29, 2013 at 5:02 pm

    I was just wondering about what causes various results today. Have you ever decreased the total amount of sugar in the recipe? I like my cookies less sweet and am wondering how that affects the texture.

  53. #
    Kim — July 29, 2013 at 5:34 pm

    What an amazing post! I’ve tried cookie recipes where they came out “not quite right” but I wasn’t sure what made the cookies too crispy or flat or whatever so I ditched those recipes. Now I can go back and try them again with a little tweak from your handy guide. Bottom line: you’re a genius and thank you!~

    Thank you for such a definitive study (and for all that baking research). I think I’ve made all those cookies, myself, just accidentally! Posting to my “Recipe Box” on Pinterest.

  56. #
    Bev Napurski — July 29, 2013 at 6:46 pm

    Great test! Interesting how small changes make such a big difference! I have used the Crisco recipe for many years and always get rave reviews. Other tip is to slightly under cook them – if you like chewy cookies! Keep up the great work!

  57. #
    Laurie — July 29, 2013 at 6:56 pm

    I like to substitute some whole wheat flour in many of my recipes. Did you consider that for one of your variations? What are your general experiences with such a substitution?

  58. #
    Rosemary Mark — July 29, 2013 at 8:18 pm

    This was excellent research and beautifully shared, thank you! I can imagine the project it was for you, and I’ll surely refer to your tips. Sunset Magazine did similar in 1995 and 1998. I’m not able to find it on-line but I could scan and email if you’re interested.

    jessica — July 29, 2013 at 10:22 pm

    Oh thank you! I was just thinking of doing a grand cookie experiment such as this as I was munching on my favorite bakery cookie and wondering why mine never come out that way. We were on a road trip and so my mind wandered and I wished that someone had written a book or article on cookie tips and then i found this via pinterest…!!! Yay and thank you!

    What a great article. Thank you for doing this experiment on everyone else’s behalf. I hope you managed to eat all the cookies you baked? Did you personally have a favourite? How did all your tests compare to the original control version in terms of taste quality?

  62. #
    Melissa R. — July 30, 2013 at 4:12 am

    Thanks for posting this! It explains so much. 🙂 Have you ever added vanilla pudding, dry out of the box? I have an Amish recipe that calls for that in chocolate cookies. They usually look great but seem a little dry or cake like. I just wondered if you had tried it.

  63. #

    Thank you. This is a wonderful example of kitchen science. I’ve always found that under cooking them results in the perfect cookie – chewie in the middle and crunchy at the edge.

    I’m curious about the effect of using a mixer vs. hand-stirring. I think it would have an effect on the consistency and taste. Would you consider testing that in round 2?

    This info is so helpful … my husband prefers his chocolate chip cookies to be soft and chewy. It’s always been hit or miss for me, now I will know just how to alter the recipe to make “his” perfect cookie (it’s thin and crispy for me) … hmm, they do say that opposites attract 🙂

    Great! I’ve always wanted to try something like this, but I’m not willing to “mess up” cookies on purpose! Others have mentioned it, but when you try again, I would love to see comparisons of butter, margarine, and butter-flavored Crisco. My sister used to make the Crisco version, and I imagine them now as “oily,” as you mentioned, but otherwise perfect.

    Heidi — July 30, 2013 at 10:07 pm

    This is an awesome reference! I saw it on tumblr, and I’d like to follow up with one variation I always use: I substitute honey for the white sugar (actually, I use about 2/3 brown sugar and 1/3 honey). I find that this gives the cookies a new and exciting flavor – by using different varieties of honey (I generally use acacia) you’ll get different secondary flavors to the cookies. The honey is a little sweet though, so reducing the amount of honey can work well, and I usually have to add a few more tablespoons flour because of the honey being more liquid. It results in very moist cookies though, and the great taste of the honey shines through.
    Sourwood, tupelo, or orange blossom honey are also good choices to substitute in. The honey trick also works amazingly well with peanut butter cookies or cakes.

    I start with the Toll House recipe as well. I melt my butter and while hot pour over the sugars & vanilla and mix with mixer. While mixing I add the eggs and I get kind of a melted carmel consistency. Then I add to the flour, baking soda and salt and mix by hand until thoroughly mixed. Then I add the chocolate chips. Then I chill for several hours. The cookies come out cakey & thick, with just a bit of spread, and the look of your cookie in the melted butter test. The less I chill the batter, the more of a spread I get. I like them thick so I chill as long as possible – sometimes even overnight! I get compliments on my cookies all the time!

    Shari — July 31, 2013 at 9:34 am

    Awesome post! Thanks for all your hard work. I have two questions … 1) a previous post said something about using oats instead. Is that finely ground oat flour or would you use whole oats, as in oatmeal? I adore chocolate chip/oatmeal cookies … and 2) I once tasted a version that replaced the oil in the cookies (butter or shortening) with unsweetened applesauce instead. They were obviously lower in fat but were delicious and I preferred them to the higher fat variety. My husband who would NEVER eat low fat preferred them also! Do you know anything about that addition? Perhaps I will Google it to see if I can find out more.

    Vijay @ NoshOnIt — July 31, 2013 at 10:54 am

    This is awesome Tessa – love how you went about it! I’m a HUGE chocolate chip cookie fan. It’s seriously the one dessert I can’t get enough of. It’s also the only baked good I’ve perfected. I make mine with all brown sugar (combo of light and dark), all brown butter (it makes for an amazing nutty depth of flavor), a several hour resting, and an interesting whipping/resting technique I learned from America’s Test Kitchen. Works like a charm every time. More here if you’re interested!

    So glad to see this but I have to point out that on Nestlé’s chocolate chips package, as well as on their website, they say to “Pre-heat oven to 375 degrees.”É-TOLL-HOUSE-Chocolate-Chip-Cookies/detail.aspx

    So what difference would this reflect?

    bonnie elliott — July 31, 2013 at 11:28 pm

    I have for years made my toll house cookies using 1/2 unsalted butter and 1/2 butter flavor crisco. I like my cookies to be not so crispy – have a little softness to them – and this seems to work for me. Also, I cook them for exactly 9 minutes and take them off the cookie sheet as soon as I’ve put the next pan in the oven and reset the timer. Leaving them to cool on the sheet just lets them brown more, which intensifies the crispness. I also use Reynolds nonstick aluminum foil on my baking sheets.

  91. #
    bonnie elliott — July 31, 2013 at 11:32 pm

    As an addendum: I agree with Silvia L. who said the package of chips calls for the oven temp to be 375 degrees. That is the temp I have always used.

    Allie @ so we sail on — August 1, 2013 at 5:52 am

    I stumbled on this post, and THANK YOU! I’ve been looking for an explanation like this, of what impact various ingredients have on the final product in recipes. This is such a phenomenal explanation & in chocolate chip cookie form it’s completely relatable! Every time I search, I either end up with articles that are too chemical and scientific, or too focused. Really great post!

  93. #
    Sylun — August 1, 2013 at 7:49 am

    Have you thought about trying powdered sugar? I think cookies from Asian bakeries might used powdered sugar instead. The cookies are less sweet and look like refrigerator slice-and-bake cookies.

  94. #
    Lilyann C — August 1, 2013 at 7:56 am

    I’ve been trying to find the right chocolate chip cookie. I like them crisp so I know more granulated sugar than brown would make them crispy. I haven’t found the right proportion yet. Sometimes they come out too thin. I want them crisply with a little “meat” on them. Any suggestions? Thanks. Love your post. It’s so informative.

    • #
      Tessa — August 1, 2013 at 12:27 pm

      I would definitely try chilling the dough for at least 24 hours next time – that tends to produce a cookie that is crisp at the edges and thick in the middle!

    Holly — August 1, 2013 at 12:17 pm

    Hello, I saw this and couldn’t help but comment- this link is great by the way! I use the tradition Nestle recipe shown when I lived in Florida and now that I live in Arkansas. I do/did the same things with the same ingredients and they turned out PERFECT traditional Nestle cookie in FL ,bu, are too puffy here in AR. I usually make the batter and do the “drop-cookie” method right away. I hate a “puffy” cookie and I just can’t understand why the recipe doesn’t work out like it did in FL . Can you help me? Thanks so much, loving your blog!

    • #
      Tessa — August 1, 2013 at 12:30 pm

      Thanks for your comment, Holly! That’s hard to say. It could be a number of things like the humidity or your oven. Do you have an oven thermometer? Puffy cookies can be due to baking powder or possibly to overbeating the sugar and butter. If you hate the puffy cookie you may want to try melting the butter next time!

  96. #
    Jenn Post — August 1, 2013 at 12:52 pm

    I am wondering what the final results would be if I combined a few of your changes. (ie: add 1/4 each powder and soda and using 3/4 cup of brown sugar and then chilling the dough 24 hours before baking) I plan to use some of your additions/changes and bake them soon!

  97. #
    Paula Lauerman — August 1, 2013 at 1:44 pm

    I like to use CRISCO Butter shortening for my chocolate chip cookies. I loved the chart but must say with these old eyes I had a lot of trouble reading the comments ( font too small) and the Purple Font on the Purple Background.

    Love the colors though.

    Garrett Oler — August 1, 2013 at 4:18 pm

    I hope this question was not already asked as I didn’t have/take the time to read them all. I saw once on Americas Test Kitchen, they caramelized the butter and sugar which would obviously increase the butterscotch flavor also. What might you recommend if one were to caramelize in a pan first but also want to chill for a day. Do think it would matter and would chilling change or effect what you did with the butter?

    • #
      Tessa — August 2, 2013 at 8:29 pm

      Both those techniques would definitely increase the butterscotch flavor!

    Wow what a great post! I can totally appreciate your hardwork and diligence with this experiment. I’m an avid baker, and I love chocolate chip cookies, however it seems like every time I make them they turn out different. I know baking is a science, so changing just one thing, whether it be a measurement or omitting something, it can change the entire outcome. This is exactly what your post proves. Now, I have a better idea of what happens when my cookies turnout differently than I expect.

  101. #
    sally — August 1, 2013 at 9:00 pm

    To the person who inquired about using shortening–use half butter and half shortening. I think it’s wonderful and makes a noticeable difference in the texture…hth 🙂

    Rebeca de Torres — August 2, 2013 at 3:57 am

    Hello! When dough is in the fridge for 24-48 hours, did you shape and bake the cookies inmediatly? Or you wait for the dough were at room temperature? Thank you 😉

    • #
      Tessa — August 2, 2013 at 8:27 pm

      I let the dough sit at room temperature just until it was warm enough to scoop and shape. The colder the dough is, the less spread you will get.

  103. #
    Jessica Rombach — August 2, 2013 at 4:33 am

    I use the standard recipe with a variation a friend introduced to me. I switch out the white sugar for a package (regular size) of instant pudding. I started with Vanilla but have experienced with many others like cheesecake and butterscotch. People absolutely love them. You should give it a try.

  104. #
    stealingsand — August 2, 2013 at 5:38 am

    With the chilled dough, do you bring it back to room temp before handling or work with it chilled…? It’s August in Texas and “room temperature” with a warm oven can be in the mid-to-upper 80s, so maybe I should shoot for a middle ground…?

    • #
      Tessa — August 2, 2013 at 8:28 pm

      I let the dough sit at room temperature just until it was warm enough to scoop and shape. In Texas summer that shouldn’t take very long at all! The colder the dough is, the less spread you will get.

  105. #
    Leaker — August 2, 2013 at 5:47 am

    I sometimes take the mixing bowl off of the stand mixer base and stir the flour in by hand. I have heard that it keeps the cookies from flattening out so much. Anyone else ever heard that?

    Luli — August 2, 2013 at 8:00 am

    This is pretty cool! I’ve been on a quest to find the perfect chocolate chip cookies and this has been super helpful and interesting 😮 It looks like you know what you’re doing, I probably have less of an idea, but I’m studying to get better at it!

    When you used the melted butter method…did you let the butter cool down before you added the sugar and waited for 5 mns. or did you add the sugar to the hot butter and then let it sit 5 mns. to let it cool? Those cookies look really intriguing, with their brownie-like tops 😮

    You did a wonderful job on this experiment. I have been baking chocolate chip cookies for decades, but am never really happy because they often come out different each time! I wondered if putting raw dough on a warm cookie sheet during baking rotations would affect the outcome…I love the chilled look/extra flour look. A little thicker, with great flavor. Nice job! Thank you.

    Thank you for this post! I am definately pinning this! 🙂 I use the Nestle recipe and follow it exactly, but I find that my cookies come out flat, almost exactly like the ones you have with all granulated sugar. I would like them to spread less; what do you think I’m doing wrong? Am I creaming my butter/sugar too much? Is my butter warmer than room temperature? Should I refrigerate them before baking? Could it be my oven? Please help! 🙂

    Thank you for this! This gives me something to think on & use. It seems like every time I make cookies they come out alittle different then I wonder why – over mixing, butter not soft enough or too soft, too much or not enough or too old flour (I don’t bake much), etc…. This is very helpful. I had heard using shortening will keep them from spreading so much, etc. but I know I’d eaten some good thick ones with just butter! This helps me alot, I’m looking forward to trying your suggestions!

    Tabatha — August 3, 2013 at 3:32 am

    Another variation that I do and has turned out to be the best in my opinion has been to replace the butter with crisco. The results are a puffy, yet chewy cookie that’s not undercooked.

  118. #
    Chanda — August 3, 2013 at 4:12 am

    Martha — August 3, 2013 at 5:54 am

    Barb — August 3, 2013 at 7:23 am

    I have also found that using half Crisco and half butter makes the best looking cookie and is delicious. Otherwise I follow the Tollhouse recipe. This was a great post–lots of fun to see all the differences. Sometimes I think it’s the one we grew up with that we love the most.

    We have a divided household. I like them a little crisp but hubby likes soft baked.

I look forward to trying these out and seeing what happens!

    Great article, thanks for taking the time to bake all those cookies. If you are going to do a Part II as I saw mentioned in one post with respect to flour types, might I suggest other sweeteners as well. Baking Truvia, Baking Splenda and Brown Sugar Splenda come to mind and when used, require half the amount of product (1/2 cup of the above = 1 cup of sugar or brown sugar). Thanks 🙂

  130. #
    Samantha B — August 3, 2013 at 7:09 pm

    Do you know if the type of pan used makes any difference? I’ve always suspected that non-stick pans make the cookies turn out differently.

    Stephanie Baker — August 4, 2013 at 6:05 am

    The melted butter picture looks most like ours. When my Grandma passed away my cousin and I realized we hadn’t written down her chocolate chip cookie recipe so he and I sat down and wrote down exactly what we remembered her doing. She didn’t ever use a mixer, (she used a big spoon, and I still use the same one) and she always melted her butter. She also SIFTED her flour, which I find makes a big difference…and causes me to leave off the two extra tablespoons of flour. We also figured out that to get the right texture…a little crispy near the edges and puffy and chewy in the middle…that we needed to use a little more brown sugar than white, so I just increased the brown sugar by a quarter cup, and decreased the white by the same amount. Now every time I make those cookies it’s like I’m a kid again and my sweet little Grandma is still with me!

    Thanks so much for this! My family is a big fan of chocolate chip cookies, and while mom is great at making them, I’m sure she’ll enjoy this. I personally am not a fan of the cookies themselves, but I do love the cookie dough! Which recipe has the best tasting dough in your opinion?

  138. #
    Crystal — August 5, 2013 at 1:47 pm

    Growing up, I always loved my Grandmother’s Chocolate Chip Cookies. When I was older, I asked her for her recipe. Turns out it was the Tollhouse recipe, but she uses 4T butter and 4T margarine instead of the unsalted butter. They turn out completely crispy…and delicious! Although there are still times when I prefer a more chewy cookie, so this guide will definitely come in handy! 🙂

  139. #
    Craig — August 5, 2013 at 1:50 pm

    Thanks so much for posting this! My kids and I make chocolate chip cookies often, using a recipe from the Mrs. Fields Cookie Book. We’ve occasionally experimented with changing the proportions of some of the ingredients, but what you present here is far more extensive and systematic than what we’ve done.

    Btw, in reference to the question from another commenter above, “How do we duplicate Mrs. Fields chocolate chip cookies at home?” — the recipe in the Mrs. Fields Cookie Book makes very good cookies, but while they are similar to the cookies sold in Mrs Fields stores, they are definitely not quite the same. I don’t know what accounts for the difference, but after reading this post, I wonder if more brown sugar and baking powder might have something to do with it… time to experiment!

    Greg R — August 5, 2013 at 7:29 pm

    Ironically (given the domain name), the “other” dimension of heating temperature vs. time isn’t tested here. My wife and I have found that a slightly lower temp and longer baking time, followed (after all are cooked) by a stay in the turned-off-but-still-warm oven, does a much better job of carmelizing the sugar. Not the best approach for those who like soft cookies, but for us crispy-lovers, it’s outstanding.

    (In appearance they look similar to the “all brown sugar” and “chilled 24hr” ones, just somewhat browner.)

    would love to see tests on what the cookies look like when you “over add” ingredients (similar to your spike of additional flour) — so what do cookies look like when there is too much sugar? too much eggs? too much shortening? too much soda?…

  144. #
    Gail — August 6, 2013 at 5:56 pm

    About how long do you cream the sugars and butter? I have the big Kitchenaid mixer also and I think I may be overcreaming mine. They come out of the oven beautiful, but fall flat as they cool, they also seem to spread too much. This only seems to be happening since I got the big mixer. Thanks so much!

    Ruth — August 6, 2013 at 5:56 pm

    I follow the recipe on the Nestle package, but since I love brown sugar, I always use DARK brown sugar (3/4 cup) along with the white. I also remove the cookies from the oven JUST before they look done, then let them finish cooking on the pan for a for about 2 minutes before I remove them to the rack. If I wait til they’re baked, they’re always too dry. I’m going to try the cornstarch.

    Jennifer — August 7, 2013 at 7:55 am

    This is wonderful!!
    In your future experiments, will you try various baking sheets? I’ve noticed a difference between my light and dark ones.
    Also, what difference to you think a home oven makes versus a professional oven? There is a bakery down the street from me that has wonderfully thick cookies. They also sell the dough, so I’m going to buy it to compare their dough in my oven versus their dough in their oven.

    Wow, what an amazing project! I always wondered exactly how much of a difference adding/removing/adjusting certain ingredients would affect a particular food item, and this answered it for me 🙂 I really like how thorough you were with the details of each group.

    I’m willing to eat any type of chocolate cookie, but my favorite would definitely be soft and chewy ones!

    Larry Elliott — August 7, 2013 at 8:17 pm

    Interesting experiment you did with cookie recipe to get the various results. I find everyone differs with what they expect out of a choc chip cookie because there are dunkers of cookies who expect very different results. As a previous owner of a very successful cookie business It took me several months to get the right combination of ingredients and technique to get the results I wanted and I never had a complaint. The cookies were thick (not too) and very, very,chocolate in every bite. I preferred Hershey’s chocolate chips because there superior and they offer semi-sweet and special dark as an unbeatable combo. I always chilled my cookie dough before baking and used parchment paper. My convection oven cookies came out better than my conventional oven because the browning was different. The texture was the same though. I used baking powder and baking soda and extra Lg eggs also. A very important tip is you have to know if your baking powder and baking soda is good. Testing with vinegar and water works. I would go up against Debbie Field’s cookies anyday! I had the customers who told me so!

    Layale — August 8, 2013 at 10:06 am

    Thanks for this. I use half white sugar and half brown sugar, as well as both baking powder and baking soda. Why? Because that is how my ex did it, and he made awesome chocolate chip cookies, and mine seem to turn out good. But, I will have to make some of mine now to compare with all the ones you listed to see how they measure-up. I might end up changing my recipe.

    Nancy — August 8, 2013 at 10:02 pm

    With eight children and twelve grandchildren I have baked a lot of chocolate chip cookies. We use equal amounts of white and brown sugar. We also use equal amounts of vegetable shortening and butter. On humid days you need to add about an extra 1/4 c. to 1/2 c. flour per normal batch of cookies. We almost always quadruple the Nestle Toll House Cookie recipe.

    Happy baking.

    Mariposa — August 9, 2013 at 12:01 pm

    Regarding the 2 types of flour… Bread flour and cake flour ‘cancel each other out’. Bread flour has more proteins that yield a chewier, tougher products (like bread). Cake flour yields a tender product (like cake). In fact, if you use 50% bread flour and 50% cake flour, you have 100% all-purpose flour.

    -Tips from the bakery 😉

    Vivien — August 9, 2013 at 7:37 pm

    wow, nice post, i think i prefer
    – mix of baking powder + soda
    – mix of sugar
    – chilled dough

    which is essentially New York Times Chocolate Chips Cookie which i have tried in below post

  156. #
    Jose Arcadio Buendía — August 9, 2013 at 8:53 pm

    Isn’t baking powder mostly baking soda? Maybe the issue is with the amount of leaven and the reactant instead.

  157. #
    BrianN — August 10, 2013 at 11:49 am

    Wow – LOTS of comments on your experiment. Jeffrey Steingarten would be proud of your effort. 🙂

    Several things (that I see you’ve addressed somewhat already in previous posts):

    – I would have preferred that you also included weights for your volumes (along with the requisite “cups”, etc.)

    – I also would have liked for you to include the parenthetical notes for how your experiments differed from your control batch (so as to allow me to be lazy and not have to keep scrolling up and down).

    – I’d love to see you add “less sugar” and “less butter” to your experiments. My wife is always experimenting with “healthier” chocolate chip cookies and usually just ends up putting less sugar/butter in the Neiman Marcus cookie recipe…with varying levels of success.

    All the best.

    PS: I couldn’t figure out why you wanted our “Mail” above…should read “Email”, though. 🙂

  160. #
    Jennifer — August 13, 2013 at 12:09 am

    I wasn’t able to read all the comments, so I apologize if this was already asked! I was wondering if you tried combining all of the different tests for one recipe? For example, using both baking soda and powder, part melted butter, part room temp, a little more flour, equal parts brown/white sugar, plus chilling the dough… Wonder how those cookies would turn out?!! I might have to try it bc I’m just too curious not too :). Thanks for sharing this!!

    i want to try the butter recipe but am a bit confused of the process regarding using the hand mixer.
    after melting butter+sugar, how do i continue?
    hand mix the egg?
    than hand mix the flour mixture?
    or just stirring by hand?
    many thanx for this wonderful project (-:

    Wow! Thanks for all the work you put into this. I’d like to see the results with a sugar cookie recipe. I like thick, chewy cookies that slightly crack. Almost the consistency of a molasses cookie. I have only had them one time and have never been able to duplicate them. Thanks!

    Wanda — August 20, 2013 at 10:32 am

    Hi! Love the tips, but my concern is that my chocolate chip cookies turn out hard when they get cold! 🙁 and I dont know what it is, I hope you can give me some suggestions,

  171. #
    Elise — August 20, 2013 at 1:40 pm

    You mentioned your favorite batch were the chilled ones. Both baking soda and baking powder recommend that you cook the cookies immediately after mixing, as the active ingredients in both have a quick reaction time. Baking powder has both single and double acting varieties. Perhaps you used double acting, as that can sit for a longer period of time? I know that you should never let items w/ baking soda sit for any length of time.

  172. #
    Joy — August 20, 2013 at 7:39 pm

    …Cookies made with butter usually are too soft and old tasting after a day or so vs if you use vegetable shortening which keeps them soft yet also crunchy and fresh…I just wish it was healthier.

  173. #
    Adriana mayorga — August 21, 2013 at 1:50 am

    Last year when I found out I was expecting I became obsessed with baked goods. That was my ultimate craving and we made it a goal to find the best chocolate chip cookie and after almost a year in researching and 5 experiments I can finally say we found it. I love all your details that can either change or make a cookie. We personally went with the recipe with added baking powder. The cookies are awesome and a thumbs up with my entire family ! Thank you so much for a recipe I can use again and something to pass onto my girls!

  174. #
    Bailey — August 21, 2013 at 12:22 pm

    Someone may have already shared this but or my “Bailey’s Chocolate Chip Cookies,” I use 1 stick of butter and 1 cup of shortening to get a lighter, fluffier cookie that isn’t as greasy!

  175. #
    Tessa — August 21, 2013 at 7:21 pm

    Replacing the white sugar in the Nestle recipe with a small box of instant vanilla pudding will create puffier, softer cookies, that are more flavorful and STAY soft. So good.

    Kristin (Meals Outside the Box) — August 24, 2013 at 4:26 pm

    Wow. Thanks so much for this. I have always wondered how many of the changes you made would effect the cookies. By the way, I have used shortening in peanut butter cookies and snickerdoodles. I found the recipes on King Arthur Flour’s website. My family now requests them that way. I use butter flavored shortening.

    Great post! Was wondering if you have tried not using butter but rather shortening or oils instead of butter? I love butter but my vegan friends do not. Some of my pals like to use crisco type stuff and swear by it. What you you think? Any photos?

  181. #
    Er — August 26, 2013 at 10:21 pm

    I just made chocolate chip cookies over the weekend and messed up the order – I mixed the eggs into the sugars, before adding the butter! It took forEVER to get the butter mixed into the egg+sugars, actually it was pretty full of butter-lumps when I started sifting in the flour mixture.

    The result? Flat, crispy, kinda greasy-textured cookies. Still totally edible though!

  182. #
    Karoline — August 27, 2013 at 9:54 am

    Thank you so much for this! I looooove baking, but pretty much stopped two years ago when I had to go gluten free (paleo) for health reasons (stupid autoimmune issue). I’ve recently started experimenting with alternate ingredients, and I find posts like this (and your sequel) REALLY USEFUL. Learning the principles of each ingredient will definitely make reinventing the wheel a lot easier. (And before someone suggests it, I find most gluten free flour blends kind of gross, so just no.)

    I look forward to any other experiment posts that you do!! And you’ve definitely inspired me to do some experimenting of my own. Thank you!!

    mary — August 27, 2013 at 12:24 pm

    I have the fondest memories of making Nestle’ Toll House Chocolate Chip Cookies with my Gramma. We thought we had it to a tee. But something is different nowadays. We didn’t want a thick or crispy, we liked a softer, more spread cookie. The only way I can get this now is leaving out the baking soda until I mix the flour in. If I put the soda in flour and set aside as directed, then they’ll get big and crunchy. Have any suggestions why?

    Now these cookies just made the cookie monster in me raving-mad hungry! I’ll try the dough chilled in 24 hours with baking soda and granulated brown sugar. Thanks so much for sharing this! Seeing how the cookies look like when different methods are used make it easier to choose the best method for our personal taste 😀

    Thank you so much for the cookie guide. This comes at a perfect time because lately my chocolate chip cookies have been coming out flat. The kids said the cookies don’t look good but they taste great. I have been making cookies for over 40yrs and this is the first time this has happened, now I know what to do. Thanks again.

  194. #
    Dan Leeder — October 6, 2013 at 8:42 am

    My cookies always come out like the top row #2 from left. Now I know why. It seems to me that the best cookie might be made with brown sugar, baking soda, baking powder, then frozen and thawed before cooking. How about one made with all Splenda? How would that work?

  195. #
    Kim — October 6, 2013 at 1:39 pm

    If I only have salted butter do I omit the 1/2 tsp that it calls for in the recipe?

  196. #
    Diana — October 6, 2013 at 4:41 pm

    I make the variation with both baking powder and baking soda AND put the dough in the fridge for 24 hours. The best ever!! AND I never bake on humid or rainy days (the weather affects my baking as we live in a 100+ year old farm house that “breathes” – no central A/C to control humidity)

  197. #
    Julia — October 7, 2013 at 7:49 pm

    Hi!You should try using cream of leaves the cookies w/ those fabulous crackles across the top.(It is an ingredient of baking powder)..I use
    1C white sugar
    1C brown sugar
    1C butter
    1tsp vanilla
    1tsp baking soda
    1tsp cream of tartar
    1/2tsp salt (I use salted butter)
    3C flour..bake 9 min @350

    Karen — October 14, 2013 at 4:54 pm

    Cool! Back in 8th grade, I messed with chocolate chip cookies for my science fair project. I did things such as doubling or removing ingredients. I remember that double eggs was preferred over the control recipe! Double vanilla was pretty good too, but so was removing the vanilla. Double brown sugar was baaaad!

  199. #
    Jeff — October 14, 2013 at 9:36 pm

    Hi Tessa, A friend liked your page on FB and it caught my attention. I’ve been baking cookies on and off for about 30 years now. I got back into it about 15 years ago to share with my co-workers and make people at work smile. Somehow in the process I think I made cookie addicts out of a large portion of the people I made them for. I started off religiously following the Nestle Toll House Recipe on the back of the package of the chips. Then I decided I really wasn’t happy with it so I started experimenting. I’ll share a few of my test results.

    1. Double the chips. I never had enough chips in my cookies. So I just doubled the number of chips in my cookies. The upside was people LOVED them. The down side was that you ended up with cookies with giant clumps of chips in them. I still use the Nestle chips, but they saved me when I found the mini chips. Now the cookies have double the chips but no more clumps of melted chips in them.

    2. I thought how about a “slightly” healthier cookie? I switched from Betty Crocker All Purpose Bleached Flour to Betty Crocker Whole Wheat Flour. The color of the dough and the cookies turned a little darker. The flavor did not change at all. The texture of the cookies became slightly courser when eating them.

    3. My learned lesson about butter. I was always in a rush to get things done and didn’t wait for the butter to soften. When I took the butter straight from the fridge to the bowl, I ended up with cookies that looked like the “more flour” cookies in your image. When I let the butter soften I am now getting a mix of “both” to “melted butter”…

    It’s always funny when people ask me for my cookie recipe and I tell them just follow the recipe on the bag, and double the chips. I use pure vanilla and un-salted butter and the wheat flour. Now I only use the mini-chips though. They still can’t believe I am following the recipe.

  200. #
    Jennifer — October 17, 2013 at 10:01 pm

    I usually use dark brown sugar, and use more of that than the white sugar. Is there a reason you don’t use dark brown sugar?

  201. #
    lisa — October 22, 2013 at 1:18 pm

    I love cookies (especially chocolate chip) and I am in LOVE with this post!! Definitely trying the more flour and the more brown sugar options. I’m curious, instead of butter have you ever tried the recipe with Crisco?

    Excellent experiment and documentation. Thank you.

    The brown sugar one looks very good to me and extra puffy too. I will try it without the baking powder since the soda / extra brown sugar effect seems to do the trick.

    The comment about cookies turning out different in one state vs. another has me wondering about the effect of electric vs. gas ovens. I know that the gas gives off moisture during combustion, so I have found that electric is better for breads, while gas is better for roasting meats.

    A future experiment?

    • #
      Tessa — November 6, 2013 at 9:36 am

      Good point! If only I had two different ovens at my disposal! My oven is an electric one. Maybe one day I can find a friend with a gas oven to test this theory out with cookies.

    Joshua — November 27, 2013 at 8:20 am

    I love it. Thanks for the examples of each. I’m just wondering who got to eat all your experiments? I have had varied success with my chocolate chip cookies and I think this helps me to understand the differences. I have to say in the last couple months I made some of my best cookies ever. I don’t know what it is but it might be the high humidity.

  213. #
    Donna — November 27, 2013 at 10:39 am

    My chocolate chip cookies are always considered the best by those who have had the opportunity to indulge in them. I am asked over and over to make them for various occasions. I use the original TollHouse recipe on the package, but my secret is to adjust the flour to which my hands render its perfect consistency (never a measured portion, so I cannot give you the exacts), resulting in the most soft, chewy cookie that never flattens out and is packed with flavor. My freezer is always stocked with bags of Nestle Chocolate Chips but never any cookies as they disappear faster than I can make them!

  214. #
    Carrie — November 28, 2013 at 12:38 pm

    Robin — November 29, 2013 at 5:57 pm

    I use the baking soda/baking powder recipe but I bake mine in a muffin tin. I have the 1oz scoop from Pampered Chef and it gives you a consistent chunkier sized cookie.

  216. #
    asa — November 29, 2013 at 11:07 pm

    Thank YOU!

    People make fun of me because I LOVE my chocolate chip cookies as dark brown as I can get them (so I tend to use dark brown sugar) and as crisp as I can get them without burning them. I don’t want them moist – at all. I prefer them not to be flat, but not chunky because of course, it’s too hard for them to be crisp all the way through then!

    In the old days I’d then microwave them (I don’t own & won’t use one now) for about 5 seconds which made the chips melt & the cookie remained crisp —-> A bit like heaven.

    If you have any suggestions on how to do things to produce a cookie that is overall dark & crisp without being burnt, I’d appreciate the tips!

    angela guinnip — November 30, 2013 at 2:16 am

    super glad I stumbled upon this. It explains a lot of things. I keep wondering why I haven’t been able to duplicate the recipe that my mom had many years ago. I think I have it figured out now. I think I will be making a lot more chocolate chip cookies and with results more to my liking. thank you.

    I use cold butter, directly out of the fridge, and frozen chocolate chips. Also use equal amounts of white and brown sugar. Cookie dough is cold as it goes into oven, cookies don’t spread and they stay chewie.

    Hey! I’m from Uruguay and here chocolate chip cookies are not a classic, the only “control” badge I have are some industrial ones from the supermarket that are really really crunchy and dry (hurts my gums), so I don’t know what’s normal and what’s not… in your opinion, which are the best? I’d like to bake some but don’t want a fiasco or a super hard badge no person will eat! Thanks in advanced! Really nice post

    Lots of little sidenotes on my nestle recipe now, thanks!
    Going to try 1c brown sugar + 1/2 c sugar, chilled 24 hr, and 2 tsp cornstarch.

    Also, I noticed that my alternative chocolate chip cookie recipe from a flour package, that I use interchangeably with tollhouse, has only 1 egg but identical otherwise… must not matter as much as I thought. I used to panic when I only had 1 egg, now I guess I don’t have to half the recipe anymore.

    Luke — December 13, 2013 at 9:22 am

    Do you sift your flour? I don’t know whether to trust the ‘pre-sifted’ all-purpose type.

    My cookies sometimes come out too ‘cakie’ if I don’t sift – does that make sense to you?

  225. #
    Amy — December 18, 2013 at 1:41 pm

    I am going to try 1/4 tsp BP and 1/4tsp BS and 1/2 brown sugar! I can’t wait.

    PS Do you sift the flour after you measure? I stink at measuring!

    AWESOME science experiment! 🙂

    Doris — January 2, 2014 at 8:10 pm

    Thanks for your post! My mother in law made the best chocolate chip cookies, and they were crunchy and not chewy at all. They exploded with flavor in your mouth, and were so pleasantly crunchy. I have been trying to replicate them since she passed away, unsuccessfully so far. Which of ours is the crunchiest version? I am guessing melted butter…..they look he most like moms.

  228. #
    Connor — January 4, 2014 at 8:27 pm

    I recently replaced all the butter with crisco (vegetable shortening) this produced a chewier and softer cookie, they were also airier and taller than the normal recipie. I recommend, if you are looking for these results. Have fun baking! 🙂

    Dani M — January 26, 2014 at 7:12 pm

    I usually make a double batch & refrigerate it. I bake only half a dozen cookies at a time since there are only two of us. It keeps for awhile. I prefer fresh baked to cookie jar. Interesting post! Thank you 🙂

    Jen — January 27, 2014 at 7:14 am

    This is great. My go-to recipe has 3/4 c. Brown sugar and 3 T. White sugar and they’re SO good. But talking about the melted butter, Alton Brown from food network has a “chewy”, “puffy” & “crispy”. The chewy (my favorite) has melted butter, bread flour and is chilled. Yummy!

    Let’s talk Gluten Free. I’m not a connoisseur of sweets so I don’t bake much but my daughter is strictly GF. Is the ratio of wheat flour to GF flour the same and do you recommend a specific brand that isn’t gritty?

    Thank you so much for your clear, straightforward experiment. I try different versions all of the time, but I just enjoyed them & didn’t take good enough notes to duplicate my favorites. I enjoyed reading everyone’s responses. My favorite variation is to add chopped walnuts or pecans. I love dark brown sugar, melting & creaming the butter & sugars & cooling the dough. I always use dark chocolate, a few times with dried cherries added. I’ve never tried the cornstarch. How do you think that added cornstarch affects the outcome? Thank you for your care in responding to all of these fans’ questions!

    Diana Trimble — March 12, 2014 at 1:16 pm

    Although I appreciated the detail in your article a lot, concerning what to expect if using more or less sugar/butter/flour etc., I must tell you that when I actually made the recipe, I was disappointed to find that the cookies tasted very, well, not-sweet shall we say. So I went back to check your recipe and I see that you have made errors in your conversions from cups to ounces. As I am in Europe and thus using weight measurement devices, I paid particular attention to following your notes, such as that 1 cup plus 2 tablespoons of all purpose flour equals 5 ounces or 142 grams. I followed this same formula in converting the other dry ingredients, namely sugar. But as I later discovered – a “cup” of dry ingredients is actually much closer to 8 ounces/200 – 220 grams (some sugars are sweeter and heavier). I am not sure why making this same mistake on flour and sugar would result in not-sweet cookies, if the error applies to both ingredients then one would think the proportion would be the important thing, but I am telling you that these cookies did not taste great even though I used all top quality ingredients. I think it is better to use really precise measurements in a baking recipe, not cups and teaspoons but actual weights. Thanks.

    • #
      Tessa — March 12, 2014 at 2:30 pm

      Diana – if I am understanding you, applying the same weight measurement conversion for sugar as was listed for flour is entirely incorrect. Flour and sugar do not weigh the same. If you measured 1 cup of flour and 1 cup of lead, would it weigh the same? No, and that applies to all dry ingredients. A cup of flour is about 125 grams whereas a cup of granulated sugar is about 200 grams, and that can vary depending on the brand and variety as you mentioned. All across the internet there are some great conversion calculators that can convert specific baking ingredients from a variety of volume and weight measurements. I’d recommend using that in the future when following American recipes. Additionally, as the majority of my readers are American and use volume measurements, that is always going to be my primary unit of measure, with weights given in baking recipes often. I hope this cleared up your confusion.

  243. #
    Mia — March 17, 2014 at 10:04 am

    I bake them and they always seem to turn into paper thin, rock hard, “frisbees”. They are hard to scrap off the pan and not very good so I end up saying forget it and throw them away. I follow the recipe on the package, look up recipes on line for simple chocolate chip cookies, changed the cooking time and temperature, and have even tweeked the recipe like you have done. Nothing seems to change though. I feel like why bother spending the time/money when I can buy a box and be done. Then I have someone else bake them, bring them over, and they are perfect. Why do mine always turn out like this?
    I even tried the full sheet pan recipe like my mother in law makes thinking that might work better and they turn out like a cake/brownie thickness and texture. Then the edges burn, instead of getting crispy corners everyone fights over. I’m not an expert in the kitchen, but can bake many things that come out great. Why are my cookies such a disappointment ???

    • #
      Tessa — March 17, 2014 at 8:55 pm

      What kind of pan are you using? Avoid anything nonstick or really thin. Also avoid using nonstick cooking spray. I like to use high-quality Chicago Metallic half sheet pans. Additionally, your oven may need to be calibrated. An oven thermometer can make a world of difference! Many ovens can be off 25°F, even 50°F.

    Florence — March 30, 2014 at 10:51 am

    Amazing CC review. I am a bit of a perfectionist in the cooking department, been looking for a long time a certain kind of cookie and would love some help. I would like the cookie to not spread so much (as I read more flour) but denser and thick, very tall and find gooyness in the center but crispyness on the edges. The ones I have tried spreads too much and stays very thin. Is that kind of cookie I’m searching is imposible, easy or a very good challenge? What king of proportions am I looking for? Thanks!

    Ali — May 28, 2014 at 4:41 am

    Thanks! I have been making (too) many delicious cookies lately. I’ve had the best luck with the “both” recipe using frozen chocolate chips and lining the pan with a thin coating of melted butter instead of parchment paper. It makes for crispier edges while keeping the centres gooey.

    Liz Lawrence — June 2, 2014 at 8:23 am

    Thanks so much for this experiment!! I have been in the quest for my favorite ccc recipe for years. This may be a stupid question, but this weekend I chilled my dough overnight for the first time and it was impossible to portion out the next day because it was so hard! Should I portion before chilling? Or should I let it soften out of the fridge before scooping? Thanks for your help!!

    • #
      Tessa — June 2, 2014 at 9:06 am

      Yep, just let it sit at room temperature until it’s soft enough to scoop.

    • #
      Tessa — June 16, 2014 at 3:24 pm

      It won’t be the end of the world if the egg is cold, it doesn’t have quite as much of an effect as the temperature of the butter. However, with any baking, it’s always best to use room temperature ingredients.

    Kerry Ford — August 5, 2014 at 7:04 am

    Hi! One thing I haven’t seen mentioned is that flours are regional and variations in cookies might also be the results of different flour brands. I used a special type for baking that I learned from my commercial baker mother-in-law, I forgot the name today, but will repost when I find the paper I wrote it on. There are so many different types of wheat that produce different results in baking.

    • #
      Tessa — August 5, 2014 at 9:00 am

      Hi Kerry, that’s a great point! I made an effort to include the brand of flour used so the results could be better replicated. To be honest, I haven’t noticed a huge different in the outcome of cookies using different AP flours (King Arthur vs. Gold Medal, etc.) but have noticed more of a difference in other baked goods like cakes. I typically use bread flour anyways which has a more standard protein content!

  256. #
    Miranda sparkman — August 5, 2014 at 8:08 am

    Wow, this is very helpful. You should try this with varied cooking temperature. I always cook my cakes and cookies at 300. Cookies and cakes stay moist and don’t get crispy. My gingerbread cookies are soft and people always want the secret recipe 🙂

  257. #
    Neil Preston — August 5, 2014 at 8:28 am

    I’d be curious to see what you think of the results of using your preferred version and 1) adding an extra egg, and 2) using soft margarine.

  258. #
    Bonnie — August 5, 2014 at 12:01 pm

    HI, Not sure if this has been brought to your attention. In the control recipe Ingredients “1 cup plus 2 tablespoons (5 ounces or 142 grams) all-purpose flour” . Should it be 1 cup plus 2 tablespoons (9 ounces) or 1/2 cup plus 2 tablespoons (5 ounces or 142 grams) all-purpose flour.
    Thank you for an interesting article. I’ll try some of your hints. I Haven’t been able to make a great chocolate chip cookie since they took the animal fats out of Crisco in the ’90s.

    I tried the baking soda and baking powder combination and here are my results:
    He cookies are completely delicious but just the slightest bit dry. They didn’t really turn out like they did in the picture (here’s a picture of mine: but maybe that’s because I didn’t cook them on parchment paper. Unless you have something better, I definitely recommend this recipe and I’m so glad I found this guide to the perfect cookie!

    • #
      Tessa — August 12, 2014 at 10:36 pm

      I’m glad you found it helpful. Thanks so much for including a picture, it makes it so much easier to offer suggestions. Looking at it, the cookies seem unusually pale (do they appear that way in person?) so my first thought is that your baking soda may actually be expired. Baking soda promotes browning. To test for freshness, place 1/4 teaspoon in a bowl and pour 1 teaspoon distilled vinegar on top. If it bubbles up, it is fresh. If nothing happens, throw away. Another question pops in my mind when looking at the pic – did you use an electric mixer to beat the dough? It looks as though the dough may not have been totally cohesive before being baked, if that makes sense. If you were following the Nestle Tollhouse recipe base, the cookies should definitely not be dry. Is is possible the flour was mis-measured? I actually find that recipe on the greasy side!

    I’m on the hunt to make by cookies higher, thicker, and softer so I’m hoping extra flour and extra egg yolk will fix that problem. But how did the extra flour not make the cookies dry in the end? I’ve always heard that extra flour would make cookies drier, not softer. Was the extra flour much softer/ ooey-gooier or did some of them come out dry? Please reply! Thanks for the post.

    • #
      Tessa — February 23, 2015 at 3:03 pm

      Extra flour in somewhat small amounts will not make the baked cookies drier, it will make them much thicker though. Plus you’ll be adding some extra moisture in the form of the egg yolk. Also, the Nestle Tollhouse recipe is quite a wet dough anyways!

    I made your controlled recipe today using shortening instead of butter, baking soda and baking powder and also using all brown sugar. They are the best chocolate chip cookies i have ever made. I wish I could add a picture. Thanks!!!

    I had cookies at my mom’s house and liked them. When I followed the same recipe she used, mine turned out flat and seemed greasy, while hers kept the shape better and were more cake like. I’ve made them twice with the same results. She eventually mentioned that she used unbleached flour. Next time I buy flour I will buy unbleached and see if that makes a difference. It might be a variation you want to add to your experiment.

    I made choc chip cookies last night and they were cakey so I started searching and found this info. I like them flatter and with crispy edges so I tried the baking soda and powder recipe. Worked like a charm and it made the choc chip cookies I love. Thank you…thank you..thank you for this information,

    This is a great guide. Thanks for posting it 🙂 What difference could you expect if you used half butter and half Crisco shortening instead of all butter? I’ve seen a recipe like that elsewhere and I wonder what kind of texture you could expect from that. My ideal chocolate chip cookie is one that it crisp outside and chew inside and not too much chocolate chips inside (some people put lots of large chips but I prefer less chips and smaller chips).

    Danielle — December 20, 2015 at 10:34 am

    Hi! Thanks for your experiment! Have you swapped out the Semi-sweet for darker chocolate? I made cookies at my grandmother’s, using her Ghirardelli dark chocolate chips, and the spread much less than what I make at home. I’m wondering if the darker chocolate activated the baking soda more?

    Sal — December 21, 2015 at 6:43 am

    I made the base recipe in the ultimate guide (the downloadable one)… I followed the directions and made the balls and, while they were baking, the whole bunch became an enormous pizza, they splatted and sticked together. I’m so sad…

    Barbara — December 23, 2015 at 6:36 pm

    Have you ever tried mixing different shortening and butter I am told shortening make the cookies fluffier???

  302. #
    Christina — December 27, 2015 at 2:47 pm

    I made these EXACTLY according to the base recipe using the soda/powder variation for maximum spread. Zippo. I got puffy cookies that were soft (and good) but funky.

    I did it twice thinking I did something wrong… same results. Any suggestions? What did I do wrong?

    Leslie Sease — January 15, 2016 at 7:07 am

    Great post. I wonder about one more thing. The shortening: Butter, or course, makes everything taste better. Years ago I used Crisco in baking the Tollhouse recipe. Also, I used margarine – Nucoa. Did you try any of these in your tests? And if so, which so do you recommend? Thanks for taking the time to do these tests.

  306. #
    Owen — January 29, 2016 at 5:23 am

    Thank you for the guide! You know it’s good when people are still referring to it for tips three years later 🙂 I love your tip about using both baking soda and baking powder to achieve a soft in the middle, crispy at the ends result. I suppose my mistake so far has always been that I overheated the oven, I wasn’t aware that the oven is supposed to be at 350 degrees only.

  307. #
    Nathan — February 2, 2016 at 1:32 pm

    My question is, what if you change a few items in the recipe to make it less caloric. Sugar free applesauce in place of brown sugar, granulated stevia instead of sugar, and for those with gluten issues, rice flour instead of regular flour.

    You are so kind to do all this for us! Thank you – I learned so much from you and from some comments. I have used all white sugar because I can’t stand the smell of the brown and white combo. The last time I made them, they tasted good but I felt they could have had more depth so I’m taking your notes about intensifying the butterscotch flavor. You’re awesome!

    Hi, Tessa!
    I’m a new baker and I’m making a couple of cookie recipes and trying to sell them for a little bit of extra income. My husband and I have baby twins and I’m in school (plus I love to bake) so any bit helps!
    Do you have any tips on storing cookies? I tested some chocolate chip cookies in an air tight container with a tortilla underneath parchment paper to keep moist but my cookies got a tad too moist.
    I’m sure you’re super busy! Maybe you could respond when you have a chance.
    Thank you!!

    Delana — April 21, 2016 at 5:12 pm

    Thank you so much! I have a recipe that uses 1/3 cup shortening and 1/3 cup softened butter. Have you tried using shortening before? They come out very nice. They seem to stay soft longer. I’ll try the 1/4 tsp each of soda and powder to see if I get even better results. They’re great they just aren’t the best ever.

    I’m tried using 1/3+1/3 shortening/butter, 1/4+1/4 soda/powder and 3/4 cup brown sugar + 1/4 cup white sugar. They were excellent. A little puffy. They were puffy originally too. The temp on this recipe is 375° so I don’t know if that is why or not. I’ll try melted butter next time and see what happens.

    Hi Tessa, yesterday I tried to bake brown-sugar cookies according to your recipe and they turned out just horribly! Frankly, I have no idea what might have gone wrong but my cookies look like some weird mushrooms. I was wondering if you could help me with this, maybe this happened to you too and you know what might have caused it. Thx very much for response

  320. #
    Mary — June 9, 2016 at 8:48 am

    I remember years ago trying to avoid shortening and using an unsaturated oil instead, probably safflower. I remember that they spread out and were very tender, but quite tasty too. The chips stood up on top like like the recipe where you used all granulated sugar…Have you done any experiments with oil in the batter, or would you have any advice on that? I was trying to make a cookie without so much saturated fat I also used dark brown sugar since this is what I usually have in the house………..I really appreciate that you took such a scientific approach and did all this work…Thanks…From reading the comments, it looks like everyone loves chocolate chip cookies as must as I do!

    Anna Thomson — June 9, 2016 at 7:30 pm

    Hi! I used your first recipe, but realized about halfway through I didn’t have chocolate chips, so I used 3 tablespoons of hot fudge, and they came out beautiful! I’m sure they’re better with chocolate chips, but for people who’d like richer, chewy cookies, fudge works for chocolate chips.
    Anyways thank you for posting this recipe! It was fun and easy to make!

    Karen — June 10, 2016 at 12:49 pm

    Hi Tessa! I have a doubt, I am making cookies only with whole wheat flour and brown sugar because I want them more healthy. Normally I use eggs, baking soda, butter (creamed or melted) and chocolate chips or chunks as well but my cookies end up being like a cake (fluffy and with holes) I dislike them because to me cookies should be chewy, crispy, etc . How can I do to make the cookies look and taste like a real cookie? I have tried not using eggs and there was a difference but still I wonder if the eggs are the issue. Thank you for helping me! 🙂

    • #
      Tessa — June 12, 2016 at 12:13 pm

      Hi Karen! Try adding an egg yolk, the extra fat and protein creates a more chewy texture. Egg whites have the opposite effect, they create a more cakey texture. Have you downloaded my free cookie customization guide? I think you’ll find it helpful:

    Ann D Leach — July 16, 2016 at 3:40 pm

    Hi Tessa — I bookmarked this article a few years ago and came back it today after baking my cc cookies. Maybe you can help me with my question. I made cc cookies today using the same recipe I have always used, and I like it but don’t love it. I don’t love it only because the cookies are crisp rather than soft. And I do mean crisp rather than hard or crunchy. Another way to describe them is that when I try to break one in half, it crumbles rather than snaps. I’d like them to be hard to softish rather than crisp. I bake them low and slow, 300f for 20 min. I am wondering if there is too much sugar (1cup brown and 1/2 cup white), and it is crystalizing rather than melting? Any thoughts? Thank you.

    I rarely leave comments – but your ccc recipe with the melted butter deserves serious praise! I moved to Europe a little more than 10 yrs ago, and have struggle do on make good cookie sheet very since (maybe because of difference in dairy and so on). Anyway – now I make the best cookies ever, thanks to you! Family, friends and colleagues rave when I make them! Thank you! The best crispy AND chewy cookies ever! I will never use any other recipe! Pure perfection!

      Tessa — August 7, 2016 at 8:55 am

      So happy to hear that!! I’ve heard from quite a few ex-pats living in Europe that cookies don’t turn out the same. I’m really curious as to why exactly that might be!!

    Martin — September 11, 2016 at 10:04 pm

    Interesting results. I work in institutions with military recipes. For me, their cookie recipes are not only out of order, but if followed to the T – the dough is overly sticky and the cookies are of poor quality. Over time, I’ve messed with the recipes, putting the ingredients in the order they should be in (creaming method style), reduce baking soda from, for instance, 1 t. to 3/4 t. add 1 heaping t. baking powder (which is not in the recipe), and increase flour until the dough barely stops sticking to my finger tip when touched. I then, using a commercial convection oven, reduce the temperature from 300’F to between 250’F and 275’F and bake for about 12 minutes low fan. I rotate all of the pans and turn them, baking them for an additional ~ 12 more minutes until done. The results are a soft cookie in the center, with a crispy edge that most people love.

    Hello i tried the both recipe with bake powder and soda,i did not get the end result of a flatter cookie with crispy edges and softer middle the first time,so i tried it again and this time i partially flattened the cookies before baking and they turned out more like they should that what is needed to do is flatten the cookies before baking..tks much for sharing

    Thank you for helping me make the Ultimate Chocolate Chip cookie! I read all the comments and ended up in making the NY Times recipe on this page since I needed a lot of cookies. I added 4 teaspoons corn starch to the recipe but otherwise carefully measured and did exactly what the recipe said. I now understand that it’s important to cream the butter and sugars really well, to use both baking powder and baking soda, and to chill the dough first. I was in a hurry to see how they turned out so I chilled 6 cookies while the oven was warming up. I rolled each cookie into a ball before chilling and they came out perfectly uniform. I’m delighted!!

    Hello Tessa and thank you for your advice on ‘The Ultimate Guide to Chocolate Chip Cookies’, however I’m very confused as I was just reading your advice found on the link below and the recipe you give is quite different to the one you have here. For one thing, here you don’t use baking powder. Also, in this recipe you use all-purpose flour only, in the other recipe you use plain flour and bread flour… In this recipe you use 1 large egg whereas in the other you use 2 large eggs plus 1 egg yolk, etc. The difference in the batch is just 2 cookies… Could you kindly clarify. Thank you.

    Hi Tessa – stumbled on part II while researching the effect of substituting butter for shortening in a GF chocolate chip cookie recipe (author warned not to do it, but I have no shortening in the house and the time for cookies is NOW!). Thank you for giving me some specific steps to take in order to preserve the height/spread/texture of a much loved recipe. I would like to share your Guide, and it makes sense to start with part I, but I noticed that part I does not appear to have links to parts II, III, and IV! Hoping you might add those for convenience of folks who start with part I. Many thanks!

    I have a question. I have done many times this recipe, chilling my dough overnight ,and it has works very well for me. But in the last 3 times that i have made them, my cookies came out of the oven too flat and with a more chewy texture. Maybe its my white sugar because i have noticed that the crystal are way bigger than usual and the cookies are more sweet as well. Can be possible?

    Two tricks I learned while testing my World’s Best Chocolate Chip Cookie recipe and they are each equally important. First, freeze the dough balls overnight along with parchment covered trays. They next day pop them into a HOT, fully pre-heated oven. The frozen dough will not have a chance to over spread before it is baked into place and you will a beautiful, puffy cookie I promise.

Am I doing something wrong? I have been searching for a recipe that will replicate the cookies I had in elementary school that were super flat, didn’t hold once picked up and were very chewy but every time I try to change the control recipe I get the same looking cookies.

    the raw dough tastes amazing, baking the cookies right after making the dough though wasn’t a good idea and I didn’t like them at all. they were way too dry and not soft at all. Chilling the dough and making smaller portions really helped though!

    Thoughts on turning them into Chocolate chocolate chip cookies? My thought was to swap from Cocoa Powder for the flour at a 1:1 swap. Have you done this? Any texture considerations? Would you use one of the above alternates in conjunction with the swap?

  357. #
    Leili — December 15, 2017 at 12:57 pm

    I always wanted to try your cookie recipe and tips, and todays is that day. I choose the “only brown sugar” because of the texture, shape and flavour. I’m amazed with the results. I added some clementine zest, pecans and dark chocolate chips insted of milk chocolate. They came out perfect! Soft in the center and delicately crunchy in the board, roundish, and the flavour is sensational! Thanks for that! A lot!

    I bake a lot, and have spoken to people who own bakeries that go by old family recipes, and using butter over shortening or margarine is ALWAYS going to help, and butter softened is ALWAYS better than melted because the melted butter makes like a fried flat cookie! Although refrigerating cookie dough or almost any cookie doughs make a better cookie, I’ve always heard at least 2-4 hours, it’s almost like pastry dough you work with chilled dough, so it must work!

    I followed the Toll House recipe on the pkg. explicitly and they spread and ran together when I baked them. Can you help me figure out why? Thank you in advance

    I’ve always made pretty top notch cookies! Everyone seems to love them. Even the teachers at my boys school!
    But I have to say this is Amazing! I am going to try out the all brown sugar today and see how the teachers and the husband like them! Thank you for this post!! I am super excited!!

    Great site and great experiments with these cookies! I’ll try some variations.

    My mother made toll house cookies using the basic recipe, and we all loved them. Because she used an ungreased baking sheet as called for in the earliest recipes, the cookies would change shape a bit when she slid them off of the hot baking sheet; they took on a more oval shape–which we came to accept as part of the cookie. I still like them this way so I don’t let them “rest” but slide them off the sheet right away.

    I remembered this guide when I found your snowflake sugar cookies last year .(my favorite cookie recipe by the way) but was going for simple this year so made till house and snickerdoodles both were a disaster. Got hard as rock chunks. I am a true believer that baking is a science and cooking is an art. In both recipes I wanted thin crispy edges somewhat chewy middles with a good spread. Do you think both baking powder and soda in both recipes would achieve that?

    I live in Denver…baking in high altitude is always a challenge. I try every recipe ingredient/heat adjustment I find but cookies still rise and collapse into thin cookies. Suggestions?

    Your Blog is very informative. Straight to the point(about a number of things).
    One of the best I’ve seen.
    So very well scientifically researched & tested (no guessing-real results).
    Keep Up the good work .
    Look forward to trying other recepies.
    “The cookies are just one of my favorites”.

    This is a great study!!! Thank you so much for taking the time to do this!! One important thing – the tollhouse recipe bakes at 375°. If you bake them at 350° the sugar will never caramelize, so the cookies will be very different. (However, baking them at a lower temperature probably made some of the differences between the batches more pronounced.)

    I tried the 1/2 baking soda 1/2 baking powder recipe but my cookies look like the “more flour” example. Does anyone have thoughts on what I might’ve done one with wrong? 🙁

    Hi Tessa, Your website is excellent! I have been trying for years to bake thin, moist, chewy Toll House cookies and have tried so many ingredient variations, I’ve lost count. My cookies puff up, are hard, and are unappealing. I appreciate your recipe alterations to indicate what modifications bring about certain cookie textures. Other than ingredient variations, I’m curious, do you feel that the OVEN itself (gas or electric) has a bearing on the cookies? We have a typical ELECTRIC oven and my neighbor bakes exactly the Toll House cookies I’m hoping for (flat and chewy) with a GAS oven. Are gas stoves providing more “moist” heat that also helps cookies spread? If so, could I ever replicate this perhaps with a pan of steaming water on the bottom shelf of the oven?
    Also, nowadays, “convection” ovens are very popular. I’m so determined to get the cookies my family loves that I’m wondering if I should replace our semi-old stove! Thank you for any thoughts you can offer on ovens…I’m going to keep trying.

    THANK YOU! Thanks for sharing (in clarity and with detail) this information. SO useful in getting to the heart of the specific and obscure problem with my mealy / cake-y / corn-y chocolate chip cookies (so different from my grandmother’s gold-standard). Much appreciated, P

    When I swap the 1/4 cup brown sugar for 3/4, do I still need the granulated sugar?

    I used this recipe, with the 1/2 teaspoon of baking POWDER, and I also used the Rob’s Red Mill Gluten Free 1 to 1 cup flour, and they came out just as I wanted them to! (i even added a 1/4 cup of Rob’s Red Mill Whey Protein Powder for an extra umph)

    John R — July 26, 2019 at 5:07 pm

    I started using the Nestle recipe but despite putting the amount of flour it requiers my dough still comes out wet and sticky. Am I not putting the correct amount or does the recipe expect me to add more flour?

    What happened to “The full recipe I used to base all of the tweaks on is at the bottom of this post.”? It’s not there. Or do I have to “subscribe”? Which I’m not real keen on doing.

    Great review of different ways to prepare.
    I ended up combining baking soda and powder and the melted butter – seemed pretty perfect!

    Hi I tried making the cookies by replacing the butter with coconut oil and added flaxegg instead of the egg to make it Vegan. I used a parchment paper and measured the temperature of the oven using a oven thermometer. But my cookies din’t seem to spread at all. This not only happened once but many times when i tried using the same recipe (by making it vegan-only replacing egg and butter for Flaxegg and coconut oil respectively) for different types of cookies (eg: Red velvet, matcha). Could you please help as to why the cookies are not spreading at all?

      This could be the answer Ritika:

      Coconut oil has a melting point of 76°F.

      Unlike other oils, coconut oil can be liquid or solid — it all depends on the temperature where it’s stored. When stored below 76°F, it will firm up and solidify; at a higher temperature, it will melt into a liquid.

    I’ve been trying to perfect a chocolate chip cookie recipe to where the resulting cookie is not ‘hard’ crispy, but crisp/firm to the bite, smooth texture, and does not turn soft after sitting / storing. I had a cookie I found at a small mom/pop convenience store in Arizona. I wish I could remember the name on the label on the cellophane wrap. When I bit into the cookies (one peanut butter and one chocolate chip) they were not soft, but not hard either. I don’t know how to describe them other than to say they were more on the crispy side, but not hard. They were a bit like butter cookies in texture, but not quite melt in your mouth. Am I making any sense? I want to make cookies like those I found in Arizona. Any suggestions and/or guidance will be greatly appreciated.

    If you want to add a dry ingredient to the batter like malt powder or milk powder for additional flavoring, how would you adjust the dry or wet ingredients in order to keep it’s texture?
