Fudgy Gluten-Free Chocolate Brownies Recipe

A stack of three gluten-free brownies on a small dessert plate topped with semi-sweet chocolate chips and flaky sea salt.

These gluten-free brownies are chewy, fudgy, and intensely chocolatey. The recipe begins by blooming cocoa powder in hot melted butter, which deepens the chocolate flavor more than simply mixing in melted chocolate. A small amount of cornstarch in the dry ingredients helps keep the texture chewy rather than cakey.

Semi-sweet chocolate chips are folded into the batter and scattered on top before baking, and a final sprinkle of flaky sea salt as soon as the brownies come out of the oven brightens the chocolate. The recipe uses just two bowls — one for wet ingredients and one for dry — and requires no stand mixer. From start to finish they take about 30 minutes, with roughly 25 minutes in the oven.

Ingredient Notes

  • Cocoa Powder – I use unsweetened cocoa powder. Dutch-process or extra-dark cocoa will give a slightly richer, more intense flavor, but any unsweetened cocoa works.
  • Gluten-Free Flour Blend – This recipe was tested with 1-to-1 blends that contain xanthan gum. Bob’s Red Mill 1-to-1 and King Arthur Measure for Measure both worked well. Do not substitute almond flour in this recipe.
  • Cornstarch – Helps create a chewy brownie by thickening the batter without adding the structure that more flour would.
  • Baking Soda – Only a small amount is needed so the brownies stay moist and chewy rather than becoming cake-like.
  • Unsalted Butter – Melt and pour while still hot over the dry cocoa and sugars so the cocoa blooms and the chocolate flavor intensifies. Let the mixture rest for 2–3 minutes before adding eggs.
  • Chocolate Chips – Semi-sweet chips are recommended; use 3/4 cup folded into the batter and reserve 1/4 cup for the top. Dark or milk chocolate chips can be used to taste.
  • Flaky Sea Salt – A light sprinkle right after baking (Maldon or similar) enhances the chocolate. Optional but recommended.

Cocoa Powder vs. Melted Chocolate

Using cocoa powder instead of melted chocolate produces brownies that are chewier and fudgier with a brighter chocolate flavor. Brownies made with melted chocolate tend to be denser and very rich. If you prefer a chewy, fudgy texture, cocoa powder is the better choice.

Recipe FAQs

Can I use almond flour in these brownies?

Not in this recipe. Almond flour requires a different formulation; there is a separate almond flour brownie recipe designed for that flour.

Can I use oil instead of melted butter?

Yes. Melted butter adds flavor, but a neutral oil works if you prefer or need a dairy-free option.

Can I make these brownies dairy-free?

Yes—use oil instead of butter and choose dairy-free chocolate chips.

Can I double this recipe?

Yes. Use a 9×13-inch pan and increase the bake time by about 5–10 minutes, checking for doneness with a toothpick.

Expert Tips

  • Weigh your flour for best results. The recipe calls for 2/3 cup (93 g). Scooping can pack flour and lead to dry brownies; a kitchen scale gives the most accurate measurement.
  • Use a light-colored metal pan. Dark pans absorb more heat and can overbake the edges before the center is done. If using glass or ceramic, check a few minutes early and remove from the pan after about 5 minutes of cooling.
  • Line the pan with parchment paper. Grease the pan first so the parchment sticks, and leave a couple of inches of overhang to lift the brownies out for cleaner cuts.
  • Don’t overbake. Pull the brownies at 22–25 minutes when the edges are set and a toothpick in the center shows moist crumbs, not wet batter. Slightly underbaked brownies firm up as they cool.

Storage Instructions

Storage: Keep leftover brownies in an airtight container at room temperature for up to 3 days.

Freezer Option: For longer storage, freeze up to 3 months. Flash-freeze individual pieces on a baking sheet for an hour, then transfer to an airtight container or freezer bag. They can be eaten straight from the freezer or thawed at room temperature for about an hour.

Serving Suggestions

These brownies are delicious on their own or dressed up for special occasions. A drizzle of fruit coulis adds brightness, while a layer of chocolate or hazelnut ganache makes them extra decadent. Serve warm with a scoop of ice cream for a classic brownie sundae.
