Decadent, spicy, and of course sweet, these fudgy brownies are the perfect addition to your Dia de los Muertos spread. You can eat them any time at all though, they're amazing! Spice up these beautifully chocolatey brownies with cinnamon and cayenne pepper for a memorable dessert.

These babies are way better than boxed mix, but if you're looking for a quick fix, you can easily use boxed mix and just add in the cinnamon and cayenne pepper. Just follow the directions on the box, but make sure to use our tips for lining the pan and cutting them. No more digging brownie corners out of the pan anymore.


  • 1 1/4 cups sugar

  • 5 1/2 ounces (11 tablespoons) salted butter

  • 3/4 cup unsweetened cocoa powder

  • 1 teaspoon cayenne powder

  • 1 tablespoon ground cinnamon

  • 1 teaspoon pure vanilla extract

  • 2 large eggs

  • 1/2 cup all-purpose flour

  • 1/8 teaspoon baking soda

  • 1 tablespoon cornstarch

  • 1/4 teaspoon salt

  • 1/2 cup semisweet chocolate chips

  • 1/4 cup chopped bittersweet baking bar

Steps to Make It

  1. Gather your ingredients.

  2. Preheat the oven to 325 F. Line a 8 x 8-inch baking pan with parchment paper. Cut the paper in a square that will fit in the bottom of the pan with 4 flaps on each side that will line the sides. You can do this by making a 90-degree cut at the corners where each side meets.

  3. Place the butter and sugar in a large, microwave-safe bowl. You will do most of the stirring in this bowl, so make sure to pick one that will fit all of the batter. Heat it in the microwave for 1 to 2 minutes. Remove it from the microwave and stir. We used a whisk, but you can also use a hand-mixer.

  4. Allow it to cool on the counter for a few minutes, then stir in the vanilla extract, cayenne pepper, ground cinnamon, and cocoa powder.

  7. Gradually add the dry ingredients to the wet ingredients. Mix until the flour mixture has been completely incorporated, but do not overmix.

  8. Gently stir in the chocolate chips and chocolate bar chunks. If you are adding nuts, add them now as well.

  9. Pour the brownie batter into the prepared pan and smooth the top so that it is even.

    Place the brownies in the oven and bake for 25 to 30 minutes, or until the brownies are set.

  10. Allow the brownies to cool slightly in the pan and then lift the sides of the parchment paper to lift the brownies out of the pan.

  11. Cut the brownies when they have mostly cooled to get the cleanest cuts.

  12. Enjoy them with a cold glass of milk or a cup of Mexican Hot Chocolate.


We used the brownie base from Life Made Simple. They are simply amazing, and it took her many tries to get the perfect combination. We spiced it up with Mexican spices and subbed in salted butter for unsalted.
