Mexican Chocolate Brownies with Cinnamon Buttercream Frosting

Happy Cinco de Mayo! Friday and Cinco de Mayo?! I can’t think of a better combination than that! I am wrapping up Mexican week with these Mexican Chocolate Brownies smothered in Cinnamon Buttercream Frosting! A sweet and spicy end to your Mexican Feast!

If you have been following along all week you now have everything you need to throw your own Mexican Fiesta! Classic Guacamole for an appetizer, Pineapple Mojito Shrimp Tacos and Mexican Chopped Salad for your main entree, Broiled Grapefruit and Rosemary Margaritas for drinks and now these decadent Mexican Chocolate Brownies with just the right touch of spice!

These brownies are rich and fudgy! They are made with dark unsweetened chocolate, dark chocolate cocoa powder and loaded with chocolate chunks! The brownies are spiced with both cinnamon and a touch of cayenne and the frosting is loaded with more cinnamon. If you really want to turn up the heat you could double the cayenne in the brownies, I didn’t because Walter isn’t the biggest fan of spice… though it didn’t really matter since he decided these were too rich for his taste…

If I make a chocolate dessert and Walter decides it is too rich or too chocolatey for him that’s when I know I’ve got a good one. Seriously, it’s actually a compliment. When Walter was a kid he had his teachers and friends convinced that he was allergic to chocolate. He is not, he just didn’t like it as a kid. On his friend’s birthdays he was that kid with the special cupcake set aside due to his chocolate allergy… is that even a thing? I don’t know that you can be allergic to chocolate and if you can it is certainly not common, but he had them all beat! Since meeting me he has opened up a bit more to chocolate, but he’s definitely not a chocolate lover. These brownies are for chocolate lovers, plain and simple. I mean, look at them, the ooey gooey chocolaty goodness is practically oozing out of the screen 🙂

So go on and get started, it’s time to fiesta!
