Ingredient Notes for Success
The 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.
The Chocolate Chips

I prefer semisweet chocolate chips, but you can use any kind you like. They strengthen the chocolate flavor, thicken the texture, and help develop that shiny, crinkly crust on top.
You can also add 3/4 cup chopped walnuts or pecans in addition to the chocolate chips.
Learn my top FOUR methods for achieving a shiny thin brownie crust here.
The Fat
- Melted butter plus vegetable oil provides the best taste and texture.
- You can use avocado oil or any other neutral-flavored oil instead of vegetable oil.
- Make sure your oil is fresh to avoid any off flavors.
- Check out my side-by-side baking experiments with Butter vs Oil here.
The Sugar
Don’t reduce the sugar in this Brownie Recipe, as this will cause dry, crumbly brownies that will stale faster. Learn more about sugar’s functions in brownies here.

The Eggs
These Chewy Brownies use two whole eggs plus an additional egg yolk for EXTRA chewiness and richness. Using cold eggs prevents doming and increases moisture.
The 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.
Secret Ingredient: Cornstarch!
Cornstarch mimics the texture of box mix brownies, creating thicker, chewier brownies with a nice shiny crackly top. Don’t skip it if possible.

The Best Pan for Brownies:
Struggling with gummy, sunken, underbaked (even raw) or dry-edged brownies? Ditch the glass square pan and use a light-colored 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.
Storing & Freezing Brownies
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!
To freeze, 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
Can I double this brownie recipe?
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.
Why is there no baking soda or baking powder?
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!
Can I leave out the chocolate chips?
You can, but note that the brownies will be thinner and may not develop that shiny crust on top.
Why use melted butter instead of creamed butter?
Not only does this make the recipe quicker and easier, but it yields denser, chewier, and fudgier brownies.
Can I use gluten-free flour?
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.
Can I make this recipe dairy free?
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.
Can I make this recipe egg free?
I have not found a suitable replacement for the eggs in brownies yet. Feel free to experiment!
How to tell when brownies are done baking?
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.
What’s the best way to cut clean brownie slices?
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.

I will never use box brownie mix again. These brownies came out so delicious it’s beyond words! My husband and kids can’t get enough! Such a great recipe!
I accidentally switched my salt and sugar containers. Needless to say the second batch was much better. Would make again (without 1 and 1/4 cups of salt)! Very chewy and delicious!
Pretty sad with these. Consistency is more like cake than chewy brownies.
I have no oil, can i subsititue with some extra butter? How much would you recommend to replace 1/3 cup oil?
Holy cow these were AMAZING. Definitely my new go-to recipe! They came out perfectly at 30 minutes.
Very good and chocolatey! I used a glass 8×8 sprayed with Pam but didn’t used foil. I had to cook them for 40 minutes, but they were super yum!
Trying this one soon as brownies are a favorite of mine!
The brownies did come out moist and beautiful but my family didn’t like it. They tasted too bitter.
Delicious
