These fudgy gluten free brownies have deep chocolate flavor, a chewy center, and the shiny crinkly top you usually only get from a box.
With a full cup of cocoa powder and plenty of chocolate chips, these brownies strike the perfect balance between rich and sweet, and you'll never miss the mix.
“These are AMAZING! I was diagnosed celiac 5 years ago and have usually just used gluten free boxed brownies… never again!”
Why this recipe works
The signature shiny, crackly top on these brownies comes from melting the sugar into the butter, then beating in the eggs. Melting in the butter rather than creaming it into the sugar also makes a brownie with a fudgy, chewy center that's dense without being gooey or cakey.
A full cup of cocoa powder helps the brownies hold their shape and gives them deep, intense chocolate flavor even without any melted chocolate.
This recipe is also easy to make your own. Add nuts, swap in flavored chips for chocolate chips, or swirl in marshmallow or nut butter before baking. It's a reliable base that handles mix-ins well.
How to make gluten free brownies (step by step photos)
These photos illustrate the process of making the brownies. For full ingredient amounts, see the full recipe card below.
Melt butter and sugar
Melt these first 2 ingredients in a small saucepan until the mixture is bubbling and the sugar is dissolved. The liquid sugar will migrates to the top during baking and form the crackly crust. Fully combining these ingredients without creaming them means a fudgy brownie rather than cakey brownie with a more open crumb.
Whisk eggs and vanilla
In a large mixing bowl, whisk the eggs and vanilla until well-combined, but without incorporating too much air to keep the brownies fudgy. Slowly drizzle in the warm butter-sugar mixture while whisking constantly so the eggs don’t scramble.
Add dry ingredients
Whisk in the cocoa powder until smooth first. It will resist combining with any liquid, so we whisk it in first slowly to avoid a cloud of cocoa powder. Switch to a spatula and stir in the flour, xanthan gum (if needed), cornstarch, baking soda, and salt. There are few enough additional dry ingredients that it's not necessary to whisk them separately first.
Add the chips
Fold in most of the chocolate chips, reserving a few to scatter on top to ensure that each bite has some chips.
Transfer to the pan
Spread the thick batter into a lined and greased 8-inch metal pan. Since the batter is sticky, it can be easiest to spread evenly with a lightly moistened spatula. Top with the remaining chips.
Bake
Bake at the relatively low temperature of 325°F to give the brownies time to bake fully without burning, about 30 minutes. They're done baking when the center is no longer shiny and wet. The last step in baking will be for the thin crackly top to appear.
Cool, then chill
Cool in the pan until the pan is no longer very warm to the touch. If you try to transfer the brownies too soon, they won't be stable enough and will crumble.
To get clean slices when you cut the brownies, keep the brownies in the pan and place it in the refrigerator for an hour. Then, lift out of the pan and slice with a sharp knife into 9 equal squares.
Expert Tips
Melt the butter and sugar first
Don’t skip this step! Heating the sugar with the butter helps dissolve the sugar crystals and gives you that signature crinkly top.
Beat the eggs properly
The texture of your brownies depends on it. Beat the eggs well enough that they're fully combined, but not so much that you incorporate unnecessary air into the batter. It will help create structure and chew.
Use a light-colored metal pan
A light cast aluminum or anodized metal pan bakes evenly and won’t overheat. Avoid glass or ceramic, which retain heat and can lead to burned edges.
Line your pan, even if it’s nonstick
Use parchment or foil to make cleanup easy and ensure nothing sticks, even the corners.
Don’t overbake
The center should look just set, not fully dry. The brownies will finish setting as they cool. Since they’re dark in color, visual cues matter more than a toothpick test.
Ingredient Substitutions
Dairy free
Use a vegan butter in bar form, like Melt or Miyoko’s. For best results, avoid soft tub-style spreads. If needed, try half Earth Balance sticks and half shortening (like Spectrum or Crisco). Don’t forget to use dairy-free chocolate chips.
Egg free
Replace the eggs with two chia eggs or flax eggs. The texture will be slightly different, and flax may add some flavor, but the chocolate usually covers it well.
Corn-free
Swap the cornstarch for an equal amount of arrowroot or potato starch. Both work well in this recipe.

Gluten Free Brownie Recipe
Equipment
- Handheld or stand mixer (or whisk with stamina!)
Ingredients
- 9 tablespoons (126 g) unsalted butter, chopped
- 1 ¼ cups (250 g) granulated sugar
- 2 (100 g out of shell) eggs, at room temperature
- 1 teaspoon pure vanilla extract
- 1 cup (80 g) unsweetened cocoa powder, natural or Dutch-processed
- ⅓ cup (47 g) all purpose gluten free flour blend, (See Recipe Notes)
- ⅛ teaspoon xanthan gum, omit if your blend already contains it
- 2 tablespoons (18 g) cornstarch
- ⅛ teaspoon baking soda
- ¼ teaspoon kosher salt
- 5 ounces semi-sweet chocolate chips
Instructions
- Preheat your oven to 325°F. Line an 8-inch square light-colored metal pan with parchment or nonstick foil. Set aside.
- In a small saucepan, melt the butter and sugar over medium heat, stirring occasionally, until the mixture begins to bubble. Remove from the heat and let cool slightly.
- In a large bowl, whisk the eggs and vanilla until well combined. Slowly drizzle in the warm butter-sugar mixture, whisking constantly.
- Whisk in the cocoa powder until smooth.
- Switch to a spatula and stir in the flour blend, xanthan gum (if using), cornstarch, baking soda, and salt.
- Fold in about 4 oz of the chocolate chips. The batter will be thick and sticky.
- Spread the batter evenly in the prepared pan and smooth the top. Sprinkle the remaining chocolate chips over the top.
- Bake for about 30 minutes, or until the center no longer looks wet.
- Cool the brownies in the pan at room temperature. For clean slices, chill the pan in the refrigerator for at least 1 hour.

FAQs
Nope! A handheld mixer makes it easier, but you can whisk by hand—just be vigorous, especially when beating in the eggs and cocoa powder.
Yes, but bake for about 5 minutes less. The brownies will be a bit thinner.
Yes, but bake in two 8- or 9-inch square pans. A 9×13 pan will make them too thick to bake evenly.
Use nonstick foil or parchment. If you’re using parchment, clip it to the sides of the pan with heat-safe clips so it doesn’t shift.
Not in this recipe—but I have separate recipes for almond flour brownies and oat flour brownies that are designed for those flours.
Hey Nichole! Thanks for the recipe! These brownies are wonderful! Only one question: the recipe calls for one whole cup of cocoa powder, if I added less to make it a little less chocolatey, would the recipe still work?
No, you can’t reduce the cocoa powder and have the recipe still work, Anne. It doesn’t just add flavor, but is part of the chemical reaction in the oven!
Hi Nicole, first of all thanks for the wonderful recipes they do very well in the family and friends (who eat gluten).
A question though, in this recipe (but also some recipes for muffins, coffee cake or breakfast cake) there’s to much sugar for my taste. If I want to make it less sweet, is the best way to do that by adding flour or by diminishing the liquid?
I love to hear so that I can test without to much spoil 😏
I’m afraid you’d need a different recipe to reduce the sugar, Connie. Sugar is not only a sweetener, but a tenderizer. My recipes don’t have more sugar than is typical for a conventional version of each recipe. There’s no rule for how to reduce sugar in any recipe. Sorry!
Wonderful!
I’ve always struggled with making brownies. I just about gave up when we had to go GF. This recipe came out exactly how a brownie should be. Thank you for helping me make perfect brownies!
So glad you loved them, Marjorie. And I have to say, I agree. The brownie gold standard!
Made these for a barbecue this weekend. They were absolutely amazing! Perfect texture a little chewy with a little flaky top. And the sweetness was just perfect. Thank you so much for this great recipe!
A little chewy with the flaky top is exactly what makes these brownies my favorite, Tina. So glad you enjoyed them!
Hi, My son is allergic to corn, can you make a suggestion for a substitute for the cornstarch? Thanks!
Hi, Amanda, please see the section of the post titled: “About the corn in these gf brownies”
Thank you Nicole, l had a feeling that would be the case. I will stick to your recipe.
With appreciation
Julie
Hello Nicole, thank you – for ALL that you give. Can l use xylitol as a sugar substitute, or another unrefined sugar here?
Thank you
Julie

Hi, Julie, I’m afraid I don’t recommend using a sugar alternative here, since it’s quite drying and the sugar is such a major component of the brownies. Unrefined sugars are a different thing altogether, and they’re really just sugar, too. You might try using coconut palm sugar, but definitely be sure to melt it completely first. It is also flavorful, and will compete with the chocolate flavor.
The best brownies ever
Hello there!
If I am using earth balance butter sticks is it absolutely necessary to use shortening??
If you’re replacing the butter in this recipe, you’re changing the chemistry so your results with already be different. The only way I can recommend coming as close as possible to recreating the texture without dairy is to use vegan butter. In the absence of that, half Earth Balance and half shortening will come as close as possible to vegan butter, my best recommendation for replacing butter. The further you get from butter, the more your results will vary. Only you can decide how important the best results are to you. It will still taste great if you use all Earth Balance but the texture will vary—by how much you’ll have to find out!
I have made these twice and I’m making them a third time today. I absolutely love the flavor and chew of these brownies. We’re not gluten free but after having some good gluten free brownies at a friend’s house, I decided to make some of my own. I think these are better than the friend’s! Even my chef friend loved them.
That’s really great to hear, Schmax! Thank you for letting me know. :)
