Tessa's Recipe Rundown...
Taste: Loaded with sweet, butterscotch flavor combined with that classic M&M flavor that brings you back to being a kid. I had to add some chocolate chips in there too for more goodness! Texture: Ridiculously soft and chewy with the perfect crunch from the M&Ms. It’s kind of a texture paradox but it is oh so good. Ease: Very easy. The hardest part is practicing patience to chill the dough which is optional but will make your cookies that much better than they already are. Appearance: So bright and fun! Pros: Classic cookies everyone will love. Cons: None! Would I make this again? Yes! I’ve got some balls of dough stashed in the freezer for when the craving hits.
If you follow Handle the Heat at all, then you likely know I really like cookies. Chocolate chip cookies. Peanut butter cookies. M&M cookies. I love them ALL.
Because of that obsession, I thought I’d revamp my best M&M cookies recipe that was originally published in 2015 with all the tips, techniques, and improvements I’ve learned and made since then.
My goal for this recipe was to truly let the M&M candies shine. I find this is best done with a perfectly balanced cookie dough that I ever so slightly underbake so it’s still super soft in the center. Just the thought of the contrast between that soft center and the crunchy M&Ms is enough to make my mouth water.
These cookies also feel pretty nostalgic to me. From elementary school through high school growing up, the cafeteria always sold M&M cookies for $.25 each. Eating one of those cookies was always a highlight of my day. But I have to say… they’re even better when made from scratch!
Butter: always use unsalted butter so you can control the amount of salt used, and make sure your butter isn’t too warm (more details below).
Granulated sugar: Sweetens but also helps give these cookies some spread and chew.
Brown sugar: I love nothing more than that butterscotch flavor and soft texture brown sugar gives cookies!
Pure vanilla extract: The aroma tells your taste buds to get ready for something delicious.
Eggs: two large eggs and one egg yolk for extra chewiness, all at room temperature.
M&Ms: I used regular size M&Ms for the perfect crunch in this recipe, but you could also use mini or even peanut M&Ms if you prefer!
Chocolate chips: For that gooey texture.
Why are my cookies flat?
Butter temperature is KEY!
If your butter gets too warm at any stage before baking your cookies, you’ll likely end up with flat sad cookies. Start with butter at a cool room temperature, about 67°F. Then keep the dough around that temperature until it hits the oven.
In the image below, both cookies came from the same batch of dough, baked (separately) in the same oven at the same temperature for the same amount of time. The only difference? The cookie on the right came from the last bit of dough that had sat on the counter near a sunny window for about half an hour before baking. In that time, the dough warmed up considerably and the resulting cookies look melted and flattened.
What a difference, right?! If you’re baking multiple batches of cookies over a period of time, pop the remaining dough in the fridge while they wait to enter the oven.
How long to cream butter and sugar for cookies:
There are lots of factors that influence the speed at which your butter and sugar will become properly creamed. Temperature, mixer power, paddle size and shape, the amount of butter you’re creaming, etc.
Generally, two to three minutes at whatever your hand or stand mixer’s version of medium-high speed is perfect in my kitchen for cookies. Check out more instructions and tricks on this in my How to Cream Butter & Sugar article.
Why you should chill your cookie dough!
Another thing that makes your cookies that much thicker and chewier is chilling your dough! It might be a little annoying to see that I call for chilling the dough for a minimum of 24 hours in this recipe. But believe me, it makes a big difference here. Both the taste and texture improve during this time. Think of it as a marinating time where everything just gets better and better!!
If you can’t wait, bake off a few cookies to satisfy your craving now, then save the rest for baking after the dough has marinated.
How long to bake M&M Cookies:
Don’t overbake these! I prefer to take them out of the oven just before they look done when the top center still looks a bit ‘wet’, around 11 to 13 minutes in my oven.
The residual heat of the oven and pan will continue to cook the cookies to soft and slightly gooey-in-the-middle perfection.
How to freeze cookie dough:
Make the cookie dough as the recipe directs. Use a large (size 20) spring-loaded cookie scoop to portion out balls of dough onto a parchment lined rimmed baking sheet.
BONUS TIP: If the recipe calls for chilling or ‘marinating’ the cookie dough (which does WONDERS for your cookies as described above), be sure to allow the dough to marinate before shaping and freezing.
Place the tray of cookie dough balls in the freezer. Freeze until firm and solid.
Remove the balls of cookie dough to a labeled and dated airtight container.
Cookie dough can be stored in the freezer for up to 6 weeks.

Ingredients
3cups(380 grams) all-purpose flour
1teaspooncornstarch
1teaspoonbaking soda
1 1/4teaspoonsfine sea salt
2sticks (227 grams) unsalted butter,at room temperature
1/2cup(100 grams) granulated sugar
1 1/4cups(247 grams) lightly packed light brown sugar
2teaspoonsvanilla extract
2large eggs,at room temperature
1egg yolk,at room temperature
1(12 oz or 340 gram) bag M&M® candies
1/2cup(85 grams) semisweet chocolate chips
Directions
If baking the cookie dough immediately, preheat the oven to 350ºF. Line baking sheets with parchment paper.
In a medium bowl, whisk together the flour, cornstarch, baking soda, and salt.
In a large mixing bowl, use an electric stand or hand mixer fitted with the paddle attachment to beat the butter, granulated sugar, and brown sugar on medium-high speed until light and fluffy, about 2 to 3 minutes. Scrape down the bowl before adding in the vanilla, eggs, and egg yolk, beating well after each addition, and scraping down the bowl as needed. Slowly beat in the flour mixture. Stir in the M&M candies and chocolate chips with a rubber spatula, reserving about 1/4 cup M&Ms to garnish each cookie dough ball.
For best results if time permits, wrap dough in plastic wrap and refrigerate for at least 24 hours but no more than 72 hours. This will improve both the flavor and texture of the cookies. Let dough sit at room temperature just until it is soft enough to scoop.
Using a large (size 20) spring-loaded scoop, divide the dough into 3-tablespoon sized balls and drop onto prepared baking sheets. Press a few extra m&m candies into the top of each ball of dough.
Bake at 350°F for about 11 to 13 minutes, or until golden brown but still ever so slightly wet looking on top. Cool for 5 minutes before removing to a cooling rack to cool completely. Cookies can be stored in an airtight container at room temperature for up to 3 days.

BEST. COOKIES. EVER. I have been scouring the world in search of a cookie that is perfectly chewy in the middle and crispy on the edge—this is that cookie. And it has m&ms, which I am definitely going to be using instead of plain choco chips from now on
I made these cookies for my family and while we all agreed they were good, they weren’t great, and not sure I will be making them again. They did bake up soft, as promised, but were really nothing special. I have to admit, I have been doing a lot of whole grain baking lately. I decided to try this recipe as an indulgence. Maybe our palates having gotten used to the flavors of whole grains and less sugars, or maybe we would have been better off with a different recipe.
I’m getting ready to make the M&M cookies but noticed that the recipe calls for cornstarch but when preparing it does not say to mix it anywhere. So do I include it in the flour mixture or leave it out?
Hi Cynthia, so sorry about that! You would add the cornstarch with the flour, baking soda/powder, and salt. I just added that to the directions! Thanks so much for bringing that to our attention, enjoy your cookies! 🙂
I hate to leave a bad review. But these cookies were awful. Followed the recipe exactly as written. They were very, very greasy once baked. Took them to my In-Laws today for our Easter Celebration. Was so embarrassed when people started throwing them out. And then avoiding them all together. Very disappointing, especially after reading all the glowing reviews (which is why I made them to begin with). Would not recommend making this recipe. Definitely find a different one. Sorry.
Great recipe! It made big, soft & chewy cookies! I didn’t have time to chill for 24 hours but next time I definitely will. Some of them spread and some didn’t. Either way, I’m definitely making them again! Fir those asking, add the cornstarch to the dry ingredients.
I would like to make these cookies however as one comment mentioned the cornstarch, its not stated in the method and I am not sure if to add or not add the cornstarch into the cookie mix. Please can you let me know.
This is my new go-to recipe for cookies. M&Ms worked beautifully and today I’m subbing chocolate chips. Thanks Tessa! These are such a hit when I bring them into work 🙂
I will be making these cookies soon! I’m confused as to when to add the cornstarch? 2 tsp. cornstarch are listed in the ingredients, but NO where is that particular ingredient mentioned in the instructions. Am I missing something? Please clarify. I need to make these soon for an event so need to know. THANKS!
