Flourless Mexican Brownies

Add a little cayenne pepper and cinnamon to your brownies and you have the best sweet and fudgy Mexican Brownies! They are gluten free and topped with a creamy chocolate frosting.

Gluten Free Mexican Brownies are rich, fudgy, flourless and delicious!

I couldn’t tease you on Instagram and not share this recipe with you. After all, I tested these brownies many many times to get the flavor perfect. Or maybe that was just an excuse to eat more brownies. Don’t tell anyone my secret.

Brownies are a great way to start the weekend. But these are not just any brownie, they are packed with a little spice and topped with creamy sweet frosting. Bake a batch of these flourless Mexican brownies, share them with your friends and family and I promise that they will love you forever.

It is amazing how much flavor a few teaspoons of spices can add to a dish. Chocolate enhances and complements the flavor of spices. The cayenne pepper adds a little kick. In fact, if you didn’t know cayenne pepper was in these brownies, I’m not sure you could guess what spices are added. The flavors combine to create a brownie that you will love.

Gluten Free Mexican Brownies are rich, fudgy, flourless and delicious!

If you don’t like frosting or want to cut back on the sugar, you can eat these brownies without the frosting.  Sometimes I am impatient and eat the batch before I get a chance to frost them. Without the frosting they are just as rich and flavorful.

Flourless Mexican Brownies
Save Recipe


    For the brownies:
  • 6 tablespoons unsalted butter
  • ¾ cup granulated sugar
  • 8 ounces semisweet chocolate, chopped
  • 2 eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 tablespoon unsweetened cocoa powder, sifted
  • 3 tablespoons cornstarch, sifted
  • 1/4 teaspoon salt
  • 1/4 teaspoon cayenne pepper
  • 1 teaspoon cinnamon
  • For the frosting:
  • 8 tablespoons (1 stick) unsalted butter, at room temperature
  • 2 cups confectioners' sugar
  • 1/4 cup unsweetened or Dutch processed cocoa powder
  • 1/8 - 1/4 teaspoon cayenne pepper, to taste
  • 1 teaspoon ground cinnamon
  • 2 tablespoons heavy cream


  1. To make the brownies, preheat oven to 350 degrees. Line an 8x8 square pan with foil and spray lightly with baking spray; set aside.
  2. In a small saucepan set over low heat, melt the butter. Stir in the sugar until incorporated. Add the chopped chocolate, stirring until smooth. Remove from heat and add the eggs, one at a time. Add the vanilla extract and stir until incorporated.
  3. While mixing, slowly add the cocoa powder, cornstarch, salt, cayenne pepper and cinnamon. Using a hand mixer on high speed, beat the batter until smooth and shiny, 1 to 2 minutes. (You can also do it by hand, beating vigorously.)
  4. Pour the batter into the prepared pan and bake for 25 to 30 minutes or until the brownies are set in the center. Remove from oven and let cool in the pan for at least one hour.
  5. To prepare the frosting, in a bowl of a stand mixer fitted with the paddle attachment, add the butter and beat on medium speed for one minute. Slowly add the confectioners' sugar, cocoa powder, cayenne pepper and cinnamon. Mix until combined, scraping down the sides of the bowl as needed. Add the heavy cream and mix until light and fluffy, about 2 to 3 minutes. Spread the frosting over the brownies, remove from pan and slice before serving.

    These look amazing! I’m curious to try them. I’ve never had flourless brownies before. And I’ve never even heard of adding cayenne pepper. You say it gives them a kick, does that mean they are actually spicy? My family doesn’t like hot spicy, but is this hot spicy?

    • Ashley

      Hi, Erica! You won’t even be able to tell that they are flourless brownies and they aren’t spicy at all. I don’t like spicy food, so trust me, you will love these!

    My husband loves Mexican brownies (I’m allergic to cocoa, so I just drool over them)..but I’ve never attempted a flourless version! I bet these are scrumptious! Definately going to have to make these for him♡ Thanks for sharing! Cheers! 🙂

  17. Nikki Frank-Hamilton

    I am in love! Will you marry me?? I am gluten free and have been craving a warm brownie topped with ice cream. And here you are!!! And there is no flour, none at all. I have tried gluten free cake mixes and they still bother my stomach, this is perfect! Let me reiterate…will you marry me??? LOL! Pinning!

  18. Kaitlin

    I made these for my husband, a notorious brownie lover, in honor of Cinco de Mayo. The texture of the brownies are good and the frosting to brownie ratio was perfect. But in the end, neither of us really thought the spices were necessary. After tasting the batter (spicy!) I did not include any cayenne in the frosting in hopes of balancing out the flavor. These brownies are good and I will probably be making them again, though sans spices.

    • Ashley

      Hi, Kaitlin! I’m glad to hear you liked the brownies. But I’m sorry to hear you didn’t like the spices. The brownie batter will be spicier than the actual brownies. Once they are baked, the flavors spice is less noticeable. You can certainly omit the cayenne pepper and cinnamon if you want.

    I made these for our Teacher Appreciation Lunch and had to taste a few that didn’t fit on the plate… FABULOUS! I’m not a huge fan of cayenne, but I added it anyway, and I love the teeny tiny kick it gives these brownies! They are so fudgy and seriously wonderful. I am a fan of gluten free desserts that don’t have any kind of flours in them, and these are now on my favorite list!! Thank you!!

    • Ashley

      Hi, Tangie! You are very welcome. I am so glad to hear that everyone loved the brownies! Make sure to check out some of my other gluten free desserts 🙂

  20. Anna @ Sunny Side Ups

    Omg, these look AMAZING!! 🙂 Mexican brownies are my absolute favorite kind; you just can’t beat that chocolate and cinnamon combo! And that frosting looks so thick and decadent; I love it!

    Um. These look amazing. And Gluten free?!?! yes! (if only they were carb free too hahahaa) Totally pinning to try later – maybe for this weekend (nieces and nephews are coming over!)

  41. Catherine

    Dear Ashley, what a stunning batch of brownies. I love flourless chocolate desserts, but the heat in these are fantastic. Absolute perfection. xo, Catherine

  42. Allison

    These look delicious, and appear simple enough to make on a week night! One question, why do you call for two different type of cocoa powder? Will it make a difference in the taste of the icing if I just use what I have on hand, which is unsweetened cocoa powder. Thanks!!

    • Ashley

      Hi, Allison! You can use unsweetened or Dutch processed cocoa powder in this recipe. I updated the recipe to say that.

      • Allison

        Wow! I made these for my daughters birthday, the brownie was the bottom layer of a small ice cream cake, and everyone LOVED them! Loads of people asked for the recipe. I left out the spices for this occasion, but with fall coming, I’ll try making them with the spicy flavors. I’m sure they’ll be just as delicious! THANK YOU!!

  43. Catherine

    Dear Ashley, these brownies look so decadent. Your dessert combines two of my favorite elements when comes to chocolate- a pinch of spicy and the richness of a flourless cake. I must give these a try. Pinning for later. xo, Catherine
