Flourless Mexican Brownies deliver bold chocolate flavor with a warm blend of cinnamon and cayenne pepper. They’re rich, fudgy, gluten-free, and topped with creamy chocolate frosting—all in under an hour.

These flourless Mexican brownies are a delicious twist on a classic favorite. Made without all-purpose flour and with pantry-friendly ingredients, they’re dense, fudgy, and full of chocolate.

• Semisweet chocolate — chopped; swap for dark chocolate for a deeper taste.
• Eggs — provide structure and silky texture.
• Vanilla extract — enhances chocolate flavor.
• Unsweetened cocoa powder — intensifies chocolate notes and keeps the recipe gluten-free.
• Cornstarch — creates a chewy, fudgy crumb without flour.
• Cayenne pepper — a small amount adds a pleasant heat; adjust to taste.

For the Frosting

• Butter, confectioners’ sugar, cocoa powder, cayenne pepper, cinnamon, and heavy cream — combined into a creamy, spreadable frosting with a hint of spice.

Steps to Make Flourless Mexican Brownies

Make the Brownies

1. Prep the pan: Preheat the oven to 350°F (175°C). Line an 8×8-inch (20×20 cm) square pan with parchment paper or foil and lightly grease it.
2. Melt butter and sugar: In a small saucepan over low heat, melt the butter. Stir in the granulated sugar until smooth.
3. Add chocolate: Add the chopped semisweet chocolate to the butter mixture and stir constantly until the chocolate is fully melted and glossy. Remove from heat.
4. Incorporate eggs and vanilla: Whisk in the eggs one at a time until incorporated, then stir in the vanilla extract.
5. Mix dry ingredients: Gradually add the cocoa powder, cornstarch, salt, cayenne pepper, and cinnamon. Beat the batter on high with a hand mixer for 1–2 minutes until smooth and shiny, or whisk vigorously by hand.
6. Bake: Pour the batter into the prepared pan and smooth the top. Bake for 25–30 minutes, or until the center is set but still fudgy. Let the brownies cool completely in the pan (about 1 hour) before frosting or slicing.

Make the Frosting

1. Beat room-temperature butter until creamy. Gradually add confectioners’ sugar, cocoa powder, cayenne, and cinnamon, mixing until combined.
2. Add heavy cream and beat until the frosting is light and spreadable, about 2–3 minutes.
3. Spread the frosting over fully cooled brownies. Lift brownies from the pan using the parchment or foil, slice into squares, and serve.

Brownie Baking Tips and Substitutions

• Adjust the spice: Use less cayenne or substitute chili powder for a milder flavor.
• Gluten-free: The recipe is gluten-free when using cornstarch and certified gluten-free cocoa; always check ingredient labels if you need a strict gluten-free option.
• Frosting optional: These brownies are rich enough to enjoy without frosting.
• Extra chocolate: Stir in chocolate chips or sprinkle some on top before baking for more texture.
• Storage: Keep brownies in an airtight container at room temperature for up to 3 days. Freeze individual pieces wrapped tightly for up to 3 months.
