These gluten-free “Little Debbie” brownies are as fudgy and chewy as you remember, made from common gluten-free pantry ingredients. They’re simple to prepare and irresistible fresh from the pan.
Whether you like your gluten-free brownies fudgy or cakey, chewy or tender, rich or light, these Little Debbie-style brownies hit a crowd-pleasing middle ground. They deliver that classic fudge-brownie texture, not a chocolate cake masquerading as a brownie.
What makes these gluten free brownies special?
These aren’t ordinary gluten-free brownies. They’re rich and fudgy without being cloying, the kind of brownie a true brownie lover reaches for. They stay dense and chocolatey — unmistakably brownie and not chocolate cake.
Growing up I mainly remember cosmic brownies and other fudgy treats. These homemade versions capture that same nostalgic, fudgy quality while using readily available gluten-free ingredients.
When I bring these to gatherings I often skip the ganache topping if the brownies will be transported in warm conditions, since ganache can soften at room temperature. Still, the ganache adds a glossy, silky top that makes the brownies feel extra-special.
How to make these brownies
The brownie batter
This is a straightforward one-bowl recipe. Whisk the dry ingredients together, make a well, add the wet ingredients, and mix until just combined. The batter should be thick, smooth, and glossy.
Measure and combine the gluten-free all-purpose flour, cocoa powder, xanthan gum (if needed), kosher salt, and granulated sugar. Add the packed light brown sugar and break up any lumps. Make a well in the center and add room-temperature butter, neutral oil, vanilla, light corn syrup, and beaten room-temperature eggs.
Stir until fully incorporated. The batter is dense, so expect to use a little elbow grease. If your eggs or butter aren’t at the same temperature you may notice small clumps at first; continue mixing until they smooth out. If you prefer, use a handheld mixer or a stand mixer with the paddle to finish the batter, but avoid overmixing.
The ganache topping
The ganache is quick and reliable. Place chopped semi-sweet chocolate in a heatproof bowl. Heat heavy cream until it just begins to simmer, then pour it over the chocolate and let it sit briefly so the chocolate softens. Stir until the mixture is smooth.
To ensure a glossy finish that sets well, stir in a tablespoon of light corn syrup after the chocolate melts into the cream. Let the ganache cool slightly before pouring it over completely cooled brownies so it spreads evenly.
Can you double the recipe?
Yes. The recipe doubles well. For a doubled batch, you can bake the batter in a lined 9 x 12-inch pan at a reduced temperature of 325°F for about 45 minutes, but watch carefully to prevent the bottom from burning. A safer option is to split a double batch between two 8-inch square pans — they should fit in most ovens and bake more evenly.
Ingredients and substitutions
Dairy-free: Try plant-based buttery sticks (for example, Earth Balance) in place of butter, and substitute coconut cream for the heavy cream in the ganache. Use dairy-free chocolate for the topping or omit the topping if you can’t find a suitable alternative.
Egg-free: Egg replacements like ground chia-seed “chia eggs” can work in many recipes, though they may change texture. This recipe hasn’t been fully tested with chia or other egg substitutes, so results can vary.
Cocoa powder: A dark cocoa (like Hershey’s Special Dark) gives a deep chocolate color and flavor. You can use either natural or Dutch-processed unsweetened cocoa powder; if you choose natural cocoa, add 1/8 teaspoon baking soda to the dry ingredients to balance acidity.
Candy topping: Classic cosmic brownies are decorated with colorful candy pieces. Miniature M&Ms, Sixlets, or similar candy work well for a similar look. If needed, skip the candy or use a nut topping if appropriate for your diet.
Corn syrup: Light corn syrup is an invert sugar that helps prevent crystallization and gives the batter a glossy, chewy texture. You can replace it with honey (which will lend flavor) or with a neutral rich simple syrup.
“Little Debbie” Brownies
Ingredients
For the brownies
- 1 cup (140 g) all purpose gluten free flour
- ½ teaspoon xanthan gum
- ¾ cup (60 g) unsweetened cocoa powder
- ⅛ teaspoon kosher salt
- ¾ cup (150 g) granulated sugar
- ½ cup (109 g) packed light brown sugar
- 8 tablespoons (112 g) unsalted butter
- 2 tablespoons (28 g) neutral oil
- 2 teaspoons pure vanilla extract
- 2 tablespoons (42 g) light corn syrup
- 2 (100 g (weighed out of shell)) eggs
For the topping
- 8 ounces semi-sweet chocolate
- ⅔ cup (5 ⅓ fluid ounces) heavy whipping cream
- ⅛ teaspoon kosher salt
- 3 ounces miniature M&Ms candies or multicolored Sixlets
Instructions
Prepare the brownies.
-
Preheat the oven to 350°F.
-
Grease and line an 8-inch square pan with crisscrossed parchment so edges overhang, and set aside.
-
In a large bowl whisk together the flour, xanthan gum, cocoa powder, salt, and granulated sugar.
-
Add the brown sugar and work out any lumps.
-
Make a well in the center and add butter, oil, vanilla, corn syrup, and eggs. Mix until completely combined and the batter is thick and smooth.
-
Scrape the batter into the prepared pan and spread into an even layer with a moist spatula.
-
Bake in the center of the oven until the brownies are just firm to the touch and a toothpick inserted in the center comes out mostly clean, about 25 to 28 minutes.
-
Cool completely in the pan.
Prepare the topping.
-
Place chopped chocolate in a medium heatproof bowl.
-
Heat the cream in a small heavy-bottomed saucepan until it just begins to simmer; add the salt and stir.
-
Pour the warm cream over the chocolate and let it sit until the chocolate softens, then stir until smooth.
-
Cool the ganache for 2 minutes, then pour it in an even layer over the cooled brownies in the pan.
-
Scatter miniature M&Ms (Ms side down if desired) over the chocolate. Let set at room temperature about 30 minutes, then transfer to the refrigerator.
-
Chill in the refrigerator until firm, about another 30 minutes.
-
Lift the brownies from the pan using the parchment overhang. Place on a cutting board and slice into twelve equal rectangles. Use a butter knife to create a shallow seam widthwise down the center of each brownie if desired.
Storage
-
Store covered at room temperature for up to 3 days; once topped, refrigerate.
-
For longer storage, wrap tightly and freeze up to 2 months. Defrost at room temperature.
-
The chocolate coating may develop light white streaking (bloom) over time, which won’t affect flavor.

Notes
Hershey’s Special Dark unsweetened cocoa powder is excellent here; it blends natural and Dutch-processed cocoa. You can also use natural or Dutch-processed cocoa — if you use natural, add 1/8 teaspoon baking soda to the dry ingredients.
