There’s even a secret ingredient that helps to mimic that box-mix texture (but with way better flavor!).

Absolutely amazing. From the way the brownies cracked delicately along the top crusty layer, to the gooey chocolate chips throughout…perfect chew…just perfect.
I made these and they were soooo chewy. Definitely the chewiest and crackliest homemade brownies I’ve ever made. Great recipe!

The Kitchn tested this recipe, raving about how quick and easy it is! Even Bon Appétit used the recipe as part of their research in their quest to create a perfect chocolate brownie.
Ingredient Notes for Success
Butter and Oil: Melted butter plus oil provides the best taste and texture. This is key!! You can use any neutral flavored oil that’s liquid at room temperature (such as vegetable, canola, avocado, etc.). Make sure your oil is fresh to avoid any off flavors.
Sugar: White/granulated sugar will dissolve more easily into the batter than brown sugar, helping to produce that shiny crust on top. More important notes on sugar below in the Sprinkle of Science section.
Cocoa Powder: I recommend using Dutch-processed cocoa powder for a deeper flavor and fudgier texture. Natural unsweetened cocoa will offer a more nostalgic chocolate flavor and a slightly drier but chewier texture. My favorite Dutch cocoa powder for brownies is Penzey’s or Guittard. Ghirardelli is also great in a pinch. Learn more about how Natural and Dutch-process cocoas affect your baking here.
Eggs: Two whole eggs plus an egg yolk for extra chewiness and richness. I never worry about bringing my eggs to room temp for this recipe, and it always turns out perfectly.
Flour: A small amount of all-purpose flour is essential for creating Chewy Brownies — but avoid adding too much, as this can cause dry, cakey brownies. Use a digital kitchen scale to prevent accidental over measuring. If you don’t have a digital scale, use the spoon-and-level method described here.
Cornstarch (secret ingredient!): Cornstarch mimics the texture of box mix brownies, creating thicker, chewier brownies with a nice shiny crackly top. Don’t skip it if possible.
Stop Baking Brownies In Glass or Ceramic Pans!
Struggling with gummy, sunken, underbaked (even raw) or dry-edged brownies? Ditch the glass or ceramic pan and use a light-colored alumnized metal baking pan instead.

Metal conducts heat far more effectively. If all you have is glass or ceramic, add an extra 5-10 minutes baking time. Learn more about the differences between Glass vs. Metal Baking Pans here.
Sprinkle of Science (open me!)
If you want that crinkly, shiny thin crust on your brownies, don’t skip the chocolate chips! The key to that crust forming is getting enough dissolved sugar into your brownie batter. This can be tough to do consistently, so adding chocolate chips (which contain dissolved sugar already!) is a great shortcut. Learn more about that shiny brownie crust here.

I’ve done extensive experiments with the amount of sugar in this brownie recipe. The takeaway? Reducing sugar yields drier, crumblier brownies that stale quickly. It also prevents that shiny crust from developing on top.


Storing & Freezing Brownies
Serving: For best texture and taste, allow the brownies to cool to room temperature fully before slicing and serving. Easier said than done! But warm brownies will taste more sweet and won’t be as chewy in texture.
Room Temperature & Fridge: Store in an airtight container for up to 3 days at room temperature or up to 5 days in the fridge. They are fudgier when they’re chilled!
Freezer: Wrap the cooled whole slab or individual slices of brownies in plastic wrap inside an airtight container. Store in freezer for up to 3 months. Thaw overnight in the fridge, or for a couple hours at room temperature, before serving.
FAQs
Yes! Double all ingredients and bake in a 9 by 13-inch light-colored metal baking pan (don’t use a glass pan!) and add a few minutes to the baking time.
I prefer no baking soda or baking powder for rich, dense brownies that are not even remotely cakey. If you’re team cakey, don’t even bother with this recipe. It’ll be far too chewy and fudgy for you!
You can, but note that the brownies will be thinner and may not develop that shiny crust on top.
Not only does this make the recipe quicker and easier, but it yields denser, chewier, and fudgier brownies.
I haven’t tested that, but readers have had success with a 1:1 gluten-free flour blend. You may need to add 1/4 teaspoon xanthan gum if your GF blend doesn’t have any binders.
Yes, replace the butter with an equal amount of a vegan butter block that’s firm at room temperature. Use dairy-free chocolate chips. Or, try my Coconut Oil Brownies with dairy free chocolate instead.
I have not found a suitable replacement for the eggs in brownies yet. Feel free to experiment!
A cake tester or toothpick inserted into the center should come out with moist crumbs attached. For me, 30 minutes yields my perfect brownie that’s just ever-so-slightly gooey in the center. If you prefer a drier consistency, bake for 33-35 minutes.
Surprisingly, the best tool is a plastic knife! Yes, like the ones you buy for a picnic or BBQ. If you don’t have one, use a large sharp knife and run under hot water and wipe off after each slice.

They look so yummy want to bake it now.cannot wait for tomorrow .thanks so much
Is that you mean natural cocoa? I normally use only dutch processed cocoa ,thanks
I live in Globe, AZ. Do I need to change anything because of higher altitude? I really want to make these!
Hi Brenda! I’m not really sure because I’ve never baked at a higher altitude. If you find that you normally need to make adjustments for a recipe to turn out, then I would stick to whatever you normally do. Good luck!
Recipe works awesome they taste better than store bought , only thing I didnt add was the extra egg yolk but still turned out great
Glad you enjoyed the recipe!
Finally!!! A recipe that delivers chewy brownies with a shiny top, just like the ones from a mix. I realized some time ago that without vegetable oil I was never going to achieve that effect from scratch, but all the brownie-mix copycat recipes out there still looked wrong. But yours is just perfect–plenty of butter for flavor, no water to dilute the batter, and the corn starch seemed like a genius idea. I was nervous during baking, as these puffed up like a souffle, but they settled into exactly the brownies I’ve been trying to make for YEARS. Next time I will heed your advice about the cold eggs. Thank you, thank you, thank you!
Hello! 🙂 These brownies look so delicious, like the most delicious ones I’ve seen in my life. My only question is how big your bakning pan was when doing them? Thank you for amazing recipes, hugs from Sweden!
Hi Alva, thank you! Did you have a chance to read the recipe? It states that an 8×8-inch baking pan is the size needed 🙂
All I can say is WOW! These are super easy to make and so delicious!! I absolutely love a chewy brownie and have never found a more perfect recipe until now! These are excellent when they are still warm with a scoop of vanilla ice cream and yummy the next day by themselves! You’ve done it again Tessa! Awesome, awesome recipe!
Ah thank you so much, Michelle!!
For some reason, these required a lot longer baking time than you listed. I had to bake them at 325 for about an hour for them to be done. I use an oven thermometer, so I know my oven was heated at the right temperature. Also, they turned out much thicker and cakier than your photos, even though I followed the recipe exactly. Any advice?
Just made these and they turned out delicious! The only thing is my top didn’t turn out shiny like yours. The only thing I did different was not use the extra yolk, which honestly, I don’t think it needed. It was moist and chewy. Could I have mixed it too much? I know it’s weird, I just like shiny tops on my brownies. Other than that it was awesome.
Thanks for all your expertise:)
Hmmm that’s strange. Although this particular recipe doesn’t have quite as shiny of a top as my Ultimate Brownie recipe: https://handletheheat.com/ultimate-brownies
Thanks for the recipe. I have just made a batch and they are gorgeous. I love brownies and I like trying different recipes and this is my favourite. Love from Spain.
Just about to make these and realize I only have cacao powder not cocoa powder. Will it still be as good or no?
Hi Tessa – these brownies looks absolutely delicious! I am definitely going to try your recipe will let you know how they turn out.
