Gluten-Free Fudge Brownie Cookie Recipe for Chewy Treats

Do you love brownies and cookies? These Gluten Free Fudge Brownie Cookies combine both: a glossy, crinkled exterior with a fudgy, chocolatey center. They’re a simple one-bowl treat that delivers deep chocolate flavor and satisfying texture—exactly what chocolate lovers crave.

This recipe yields 12 generous cookies. If you prefer smaller portions, use a smaller scoop and reduce the baking time accordingly.

Recipe Ingredient Notes

Gluten-free flour: I’ve tested this recipe with several blends, including King Arthur Measure for Measure, Cup4Cup, and a homemade mix. Results vary: some blends produce thinner cookies, others yield thicker, more compact cookies. Regardless of the blend you choose, measure precisely—adding even 10 grams extra flour can change the texture.

Dutch-processed cocoa powder: I prefer Dutch-processed cocoa for its richer, rounder flavor. Brands I like include Cacao Barry and Valrhona; Hershey’s Special Dark Dutched Cocoa is a good value option. This recipe hasn’t been tested with natural cocoa, so keep that in mind.

Chocolate: Use a dark chocolate you enjoy eating—this recipe highlights the chocolate’s flavor. Between 64% and 70% cacao works well. Artisan chocolate bars are a lovely choice here since the recipe contains few ingredients and the chocolate flavor stands out.

Instant espresso: This is optional but recommended; it enhances and deepens the chocolate flavor without adding noticeable coffee taste.

Flaky sea salt: A sprinkle of flaky salt on top adds visual appeal and a pleasant crunch. Maldon is a favorite finishing salt for this purpose.

How to create a shiny, crinkly top

That glossy, crinkled top you see on brownies comes from whisking the eggs and sugar until very thick and aerated. For these cookies, whip the eggs and sugar for about five minutes. The incorporated air helps produce the signature shiny, cracked surface when the cookies bake.

How to make the brownie cookie dough

The dough is similar to a fudgy brownie batter and does not require chilling, so timing is important. Have your trays and scoop ready before you finish the dough, since it firms up quickly.

Make the chocolate-butter mixture

• Preheat the oven to 350°F (175°C). Line two sheet trays with parchment paper.
• Place 215 grams of dark chocolate in a heat-proof, microwave-safe bowl.
• Cut 113 grams unsalted butter into small cubes and melt gently—either in a saucepan over medium heat or in the microwave. Avoid browning the butter.
• Remove the melted butter from heat and pour it over the chocolate. Let the mixture sit to melt the chocolate; stir until smooth. If needed, microwave briefly in 10–15 second bursts until fully combined.

Make the fudgy brownie cookie dough

• In the bowl of a stand mixer fitted with the whisk attachment, combine 2 large eggs, 1 large egg yolk, 125 g light brown sugar, 125 g granulated white sugar, ½ teaspoon kosher salt, 1 teaspoon instant espresso (optional), and 1 teaspoon vanilla. Whip on medium speed for about 5 minutes, until very thick and fluffy. This step is essential for the crinkly top.
• Meanwhile, sift together 125 g gluten-free multipurpose flour, 25 g Dutch-processed cocoa powder, and 1 teaspoon (4.5 g) baking powder.
• Stir the chocolate-butter mixture to ensure it’s smooth and warm but not hot. If it’s cooled and thick, rewarm gently in short microwave bursts.
• Reduce the mixer speed to low and add the chocolate-butter mixture to the whipped eggs and sugar. Mix briefly (30–45 seconds) until combined, scraping down the bowl as needed. This helps emulsify the mixture.
• Turn off the mixer, switch to the paddle attachment, add the dry ingredients, and mix until mostly combined. Finish by folding with a spatula, scraping the bottom and sides so the batter resembles thick brownie batter.

How to bake Gluten Free Brownie Cookies

The dough can be baked immediately. Gather your trays, a #20 scoop (about 3 tablespoons), and preheat the oven to 350°F so you can scoop and bake before the dough firms too much.

• Use a #20 cookie scoop (≈3 tablespoons) to portion the batter onto lined trays. Expect 12–13 cookies; the batter will look loose on the sheet.
• Sprinkle flaky sea salt over each cookie.
• Bake one tray at a time for about 12 minutes. The cookies should be slightly domed with a crinkled, glossy top.
• For perfectly round cookies, immediately after removing from the oven press a cookie cutter or a slightly larger round bowl around the warm cookie to smooth the edges. The cookies must be hot to shape.
• Allow cookies to cool on the baking pan for 5–10 minutes before transferring to a rack.
• Store leftovers in an airtight container at room temperature for up to 5 days; they’re best within the first three days.

How to make perfectly round cookies

To get neat, round edges, use a round cutter or a bowl slightly larger than the baked cookie and “scoot” the warm cookie into shape right after it comes out of the oven. Hold the sheet tray with an oven mitt or dry towel—the tray will be hot.

Note about salt in my recipes

I use Diamond Crystal kosher salt in most recipes unless noted otherwise. If you use a different brand—especially Morton’s—adjust amounts because salts vary in grain size and salinity. Morton’s tends to be denser and saltier, so use less if substituting.

Baking by weight

I publish recipes in grams because weighing ingredients yields the most consistent results. Digital kitchen scales are affordable and more accurate than measuring cups, which is particularly important with gluten-free flours that have different densities. I include some small-quantity items in teaspoons for convenience.

Note about ovens and temperatures

These recipes are tested in a conventional oven with the rack placed in the middle. Convection ovens (fan-forced) may require adjustments, as they can bake faster and dry out goods. An oven thermometer is a useful investment to ensure accurate temperatures.

Substitutions and modifications

Any changes to ingredients or technique may alter appearance and flavor. Recipes are tested as written; adjust at your own discretion.
