Who can resist a pan of brownies? How about Mexican brownies with a kick?!
Our Mexican brownies take a deliciously fudgy chocolate base (studded with chocolate chips) and add a bit of spice (cinnamon and cayenne pepper) to amp up the flavor.
Don’t worry, they’re not spicy. It’s just enough to add a subtle heat that complements the richness of the chocolate – similar to our Mexican Hot Chocolate and Mexican Crinkle Cookies.
Mexican brownies are also very easy to make. The batter comes together quickly (with a brownie mix shortcut), and bakes in just a few minutes. Only 30 minutes from start to finish!
We LOVE a pan of brownies (especially to share). They are a go-to dessert in our house and this twist on a classic is a hit!
Why we think you’ll love it:
- Brownies with a kick. Cinnamon and cayenne add a subtle spice and a delicious twist.
- Box mix makes it easy. We kept it SUPER simple by starting with box brownies! Just mix and bake.
- Ready in no time. These are prepped and ready in only 10 minutes and bake up in 20 for a quick and easy dessert that serves around 24 people!

Recipe FAQ
If you have a favorite make-from-scratch Fudgy Brownie recipe you can use that. Just add the cayenne pepper and cinnamon when you add the flour. Depending on your recipe you may need to adjust the amount of the spices used.
Allow the brownies to cool completely. To store a whole pan, lift the block out of the pan and wrap it with plastic wrap and again with foil. Sliced brownies can be placed in an airtight container or Ziploc. Store at room temperature for 2-3 days or in the freezer for up to 3 months.
