Fudgy Mint Chocolate Brownies (original) (raw)

This post contains affiliate links.

Our homemade Mint Brownies recipe has a rich, fudgy brownie base topped with creamy mint frosting and chocolate frosting. They're absolute show-stoppers!

I blame my mom for my Mint Brownies obsession; she would make them every year during the holidays, and they were everyone's favorite. Things got worse when I went to BYU and BYU Mint Brownies are everywhere! (Our recipe is better!). I love how Mint Brownies look impressive, with their pretty layers, but they’re surprisingly easy to make with basic ingredients. If you’re a fan of chocolate and mint together (hello, Thin Mints and Andes Mints!), these brownies are bound to become a new obsession.

How to make Mint Brownies:

Make Brownies: Mix sugar and oil in a mixing bowl. Add eggs one at a time, mixing well after each egg is added. Add vanilla. Add dry ingredients: cocoa powder, salt, flour, and stir until combined. Pour batter into a greased 9×13” baking pan and spread into an even layer. Bake at 350 degrees F for 30 minutes, or until a toothpick inserted in the center comes out clean. Cool completely before frosting.

Mint Frosting: Combine all frosting ingredients and beat until light and fluffy. Add more milk if you want it thinner. Spread the frosting evenly over the cooled brownies. Refrigerate while you make the chocolate frosting.

Chocolate Frosting: Combine butter and cocoa powder. Add powdered sugar, milk, and vanilla extract. Mix for several minutes until smooth and fluffy. Slice mint chocolate brownies into bars and enjoy!
