These Classic Chocolate Mint Brownies are easy to make and taste fantastic-chocolate and mint are just so great together.

We used a brownie mix for the brownie to make this recipe even easier. We like to freeze the brownie for a little while after adding the frosting and the chocolate ganache to help in cutting the brownies. It helps the cuts come out cleaner. Also, it is a good idea to wipe the knife as needed when cutting. You can cut those brownies into 9 or 12 pieces, deepening on the size of brownie you want to serve.

  • 18.4 ounce box Betty Crocker Brownie Mix plus: water, oil and eggs
Mint Frosting:
  • 3 cups powdered sugar
  • 6 tbsps butter softened
  • 1/4-1/2 tsp mint extract or peppermint extract, if preferred
  • 3 drops green food coloring
  • 4 tbsps milk
Chocolate Ganache:
  • 3/4 cup semi-sweet chocolate chips
  • 3 1/2 tbsps butter
Make and bake boxed brownie mix according to the packaged directions. Bake in a 9 x 9 baking dish with parchment paper-with extra parchment paper sticking out over the edges to lift out of the pan later. Do not over bake-check a couple minutes before 40 minutes-brownie needs to be set.
Mint Frosting:
Note: When adding the extract, begin with 1/4 tsp and taste frosting. Add more if desired. (I like the 1/2 tsp-but it may be strong to others)
After brownie has cooled completely, mix mint frosting ingredients in a mixing bowl with an electric mixer, until smooth and creamy.
Spread mint frosting on top of the brownie and place in the freezer for 15-20 minutes.
Chocolate Ganache:
After mint frosting has set in the freezer, make the ganache: heat chocolate chips and butter in a microwave safe bowl, in the microwave. Heat on 1/2 power. Stir every 20 seconds until chocolate is smooth and creamy.
Spread ganache over the mint frosting and place back in the freezer for about 20 minutes or a little more, if desired. Freezing helps with cleaner cuts when cutting the brownies (as well as wiping your knife clean between cuts).
Cut brownies store in the refrigerator.

    I’ve made these every Christmas for years. I use Duncan Hines Brownie mix and Crème de Menthe for flavoring. These are hard to resist! Cut the pieces small because they are RICH!

      Hi Karen, I am going to try Crème de Menthe next time I make these. Thanks for the tip. 😀
