These fudgy gluten free brownies have deep chocolate flavor, a chewy center, and the shiny crinkly top you usually only get from a box.
The secret? Melting the butter and sugar first. 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!”
My take
Nicole's Recipe Notes
That crackly top: It’s not luck—it comes from melting the sugar into the butter, then beating it well into the eggs.
Fudgy, chewy center: These brownies have a dense bite, but they’re never gooey or cakey.
Deep chocolate flavor: A full cup of cocoa powder gives you a rich, intense base without needing melted chocolate.
Plenty of chips: Five ounces in the batter, plus more on top, add pockets of melty chocolate.
Easy to customize: Add nuts, flavored chips, or a swirl of marshmallow or nut butter before baking.
How to make gluten free brownies
To make the perfect brownies, start by melting the butter and sugar together until the mixture is bubbling and the sugar is mostly dissolved. Let it cool slightly.
In a large mixing bowl, whisk the eggs and vanilla. Slowly drizzle in the warm butter-sugar mixture while whisking constantly so the eggs don’t scramble.
Whisk in the cocoa powder until smooth, then switch to a spatula and stir in the flour, xanthan gum (if needed), cornstarch, baking soda, and salt.
Fold in most of the chocolate chips, then spread the thick batter into a prepared 8-inch metal pan. Top with the remaining chips.
Bake at 325°F for about 30 minutes, until the center is no longer shiny. Cool in the pan, then chill for an hour before slicing for the cleanest squares.
My Pro Tip
Expert Tips for the Best Gluten Free Brownies
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 well
The texture of your brownies depends on it. Well-beaten eggs help create structure and chew—and they help trap air for that shiny top.
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.
- Lift out the brownies, slice into 9 squares, and serve—or wrap and freeze for later.

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.
These brownies are amazing!
I’m new to gf baking and a little intimidated by it all,
But your recipes have never fail me yet!
Thank you!
I’m so glad to hear it, Marie! Thank you for sharing your experience, and I’m honored by the trust you have learned to put in me! You are so welcome.
This is absolutely my all-time favourite brownie recipe, and I’ve made a good many brownies in my lifetime, both with regular flour and with gluten free flour. These are always chewy and their chocolate flavour is intense. Even if you let them dry out (which is very rare around house) they’re still wonderfully tasty. Thank you very much!
I’m so happy to hear that, Olive! Super chewy with intense chocolate flavor is just what they’re supposed to be. Thank you so much for sharing your experience!
Absolutely delicious…thank you x
You’re very welcome, Mike!
I am making several GF items for a HUGE party I am helping with, I have NOT made GF items before but the reviews for these brownies are amazing, so I am going to make them… with that being said if I want to make large amount (sheet pan size) instead of 8 separate 8×8 pans would they turn out as nice?? I would be making the batter 8x’s to fill the pan…. advice needed!! Thanks!
The tendency with a large tin of brownies is that they tend to burn on the bottom center before they bake all the way through, so I don’t recommend a thick pan of brownies in larger sizes than square. You could try baking them low and slow, but I just don’t know if it will work, Trish. It would definitely be better to make multiple smaller pans.
Why can’t I just print your recipe so I can actually see it to make it? There are too many hoops to jump through & sights to sign up for … very disappointing.

These brownies were so good! Very fudgy and chocolatey, the perfect texture!
Note to Nicole: I haven’t made one of your recipes in more than 3 weeks! I used to make them a few times a week. I was obsessed with your recipes, because I never knew it is possible to make such good GF recipes. I don’t know if you noticed that I made so many reviews across your different recipes, but thank you so much for these amazing recipes!
I have noticed, Samuel, and I’m grateful for your loyalty. You’re so welcome, and I’m glad you know know what’s possible. You can ever go back to food that’s just “good, for gluten free”!
I substituted monk fruit for the sugar for the diabetics in my house, which made the brownies taste too sweet to me, but that’s user error not the recipe :). I would recommend to anyone else to maybe do less than the 1:1 ratio the monk fruit sweetener bags recommend.
Everyone else in my house loved them and they baked up beautifully which I’ve been struggling with in GF recipes.
I will be keeping and using this recipe again – definitely best GF brownies I’ve done so far including box mixes! Just will take some trial and error to figure out my right proportion of sugar substitute.
Hi, Ryker, thanks for sharing your experience with alternative sweetener. I like monkfruit as a sugar alternative, relatively speaking, but it does tend to be sweeter, and it also tends to be drying. I always recommend that you pay close attention to the raw texture of the baked good, comparing it closely to what you see in the photos and video, and add more moisture as seems necessary to achieve something similar. Go slowly when adding moisture, though, since you can’t take it out once it’s been added.

Is your Mock Better Batter the best choice for this ?
That’s the blend I usually use for this recipe (actually, Better Batter itself, but they are interchangeable) but any of my recommended blends will do.
