These fudgy and chocolatey Mexican Brownies have a pop of flavor thanks to a little cayenne and cinnamon. Rich in flavor, these seriously addicting brownies are best enjoyed fresh or can be frozen for later.

This isnโ€™t your average brownie recipe! With a secret ingredient or two, these authentic Mexican Brownies turn out gooey, rich, and have an added twist.

The secret in this recipe is a pinch of cayenne pepper and cinnamon. Adding a hint of spice to the brownie batter helps elevates all of the flavors and makes the brownies taste extra chocolatey. The best part is that this easy dessert recipe can be stored away for a few days or frozen for later. Itโ€™s the best dessert to keep around for chocolate emergencies!

What Makes These Mexican Brownies โ€œMexicanโ€?

A little spice makes a big difference in these authentic Mexican brownies. The difference between this recipe and your everyday chocolate brownies is the addition of cayenne pepper and cinnamon. These ground spices in the batter add just a touch of heat and tons of depth.

Are Mexican Brownies Spicy?

Most recipes for Mexican brownies contain a little bit of spice, but never too much to overwhelm our taste buds. The spices actually enhance the chocolate flavor. With just a little cayenne powder and cinnamon, every bite of these brownies is elevated.

But don’t worry – if chili in your brownies isn’t your thing, you can simply omit it completely and they’ll still be delicious!

Mexican Brownie Ingredients

  • Lots of chocolate – You canโ€™t have brownies without the chocolate! Both unsweetened cocoa powder and chocolate chips are needed in this recipe.
  • Cayenne pepper – This adds the signature spicy bite thatโ€™s known to Mexican chocolate desserts. If youโ€™re not a fan of pepper and chocolate together, feel free to omit the cayenne completely or reduce it to only 1/8 teaspoon.
  • Cinnamon – Feel free to use regular cinnamon or Mexican cinnamon for a stronger and more authentic flavor.
  • Flour – I used all-purpose flour for a balanced taste and even baking.
  • Butter – This is melted alongside the chocolate chips and then added to the dry ingredients. Itโ€™s the best way to get your brownies moist and fudgy.
  • Eggs – These will emulsify the dry ingredients and help the brownies rise.
  • Sugar – Both granulated and dark brown sugar help the brownies taste sweet and earthy.
  • Vanilla extract – To round out all of the flavors.

How to Make Mexican Brownies

  1. Combine dry ingredients: Whisk the flour, cocoa powder, salt, cinnamon, and cayenne pepper together in a large bowl.
  2. Melt the butter and chocolate: Add the butter and chocolate chips to a saucepan and melt over medium-low heat.
  3. Combine wet ingredients: Stir both sugars and the vanilla extract into the saucepan with the chocolate and butter. Then mix in the eggs until well combined. 
  4. Make the brownie batter: Use a rubber spatula or wooden spoon to fold the wet ingredients into the dry. Do your best not to overmix the batter.
  5. Bake: Pour the batter into your prepared pan and bake until the center is firm and a toothpick inserted comes out mostly clean.
  6. Let them cool: Once theyโ€™re done baking, leave the brownies to cool completely in the pan, then transfer them to a cutting board to slice and serve.

Tips and Substitutions

  • If you like spice, use the full ยผ teaspoon of cayenne pepper.
  • If you donโ€™t like too much spice, reduce the amount of cayenne to โ…› teaspoon.
  • If you donโ€™t have cayenne, you can replace it with chili powder or ancho chili powder.
  • You can leave out the cinnamon if you want a pure chocolate flavor.
  • Donโ€™t overmix the batter! Overmixing will make the brownies dense and less fudgy.
  • Want to add more chocolate? Feel free to fold extra chocolate chips into the batter as soon as the wet and dry ingredients have come together.

Storing

To store, keep the brownies in an airtight container at room temperature. Theyโ€™ll keep for up to 4 days, but remain their freshest for 1 to 2 days. You can also keep them in the refrigerator for 7-10 days, though they probably won’t last that long without being eaten!

To freeze, wrap the baked and cooled brownies in plastic wrap and store them in a sealed container or bag. They freeze well for up to 3 months.

    Isabel, I just made this Mexican Brownie recipe. Followed it exactly.
    OMGOSH!!! Fantastic. From my oven, they were done in 29 minutes. Will definitely make again for a family reunion. Thank you for sharing.

    If I wanted to add more cayenne to feel the heat, would that disturb the rest of the taste or form of the brownie?

    1. Ana @ Isabel Eats says:

      Hi Michelle! I think the brownies would be okay if you added more!

    I made these yesterday with adjustments for high altitude (Denver, CO), adding 1/4 c. flour and decreasing granulated sugar to 3/4 c. I added the cinnamon but omitted the cayenne. They were delicious! This is my new go-to brownie recipe (after 50 years of baking brownies).

  8. Berni says:

    So I cheated and used a box mix but added Espresso crystals to the water for the mix. Was a little generous with the cayenne and cinnamon. Definite hit. Don’t think I will make Brownies without cayenne and cinnamon again

    1. Ana @ Isabel Eats says:

      Thank you Berni! We’re glad you enjoyed this recipe!

    2. Crystal says:

      How much expresso Crystals did you use?

  9. Karina says:

    I also doubled the recipe and they were too mushy and too greasy. I had to throw them away.

    1. Ana @ Isabel Eats says:

      Hi Karina. Thank you for your feedback, we’ll consider this when moving forward.

  10. Doris says:

    I doubled the batch and made one pan with marshmallows on top. Added them the last few minutes of baking just to melt and brown them. This recipe makes really good brownies and much easier than the cookies.
