Chocolate Mint Brownies

Adding mint to your brownies makes for a cool twist. I love the combo of the colors and flavors and hope you do, too.

  • 4 cups sugar
  • 3 cups flour
  • cups cocoa dutch process
  • 1/2 teaspoon salt
  • 5   sticks unsalted butter, melted 2 1/2 cups
  • 8 large eggs
  • 2 tablespoons vanilla

Mint Layer:

  • 2 sticks butter, softened 1 cup
  • 4 cups powder sugar
  • 1 tablespoon milk
  • ¼ teaspoon peppermint extract
  • Few drops of food coloring pink or green

Chocolate layer:

  • 12 oz package semi-sweet chocolate chips
  • ¼ cup butter
  • 2 tsp coconut oil or shortening, if needed



  1. Grease and flour a 12 x 18-inch baking sheet.  In a large mixing bowl combine sugar, flour, cocoa and salt. Mix ingredients.  Pour in the melted butter and beat just until blended then add eggs and vanilla.  Mix thoroughly. Pour into prepared pan and bake at 350 degrees for 30-35 minutes.  Cool completely.

Mint layer:

  1. In the bowl of an electric mixer, beat butter until smooth. Add powdered sugar 1 cup at a time mixing after each addition. Mix in milk, green food color, peppermint flavoring. Mix to combine. Spread over cooled brownies.

Chocolate layer:

  1. In a microwave-safe bowl, add chocolate chips and butter. Cook for 70 seconds. Stir until smooth. If the chocolate is too thick, add coconut oil or shortening and stir until smooth and shiny. Cooking the chocolate mixture longer is the microwave will NOT make it smoother. Mixture may, also, be cooked over low heat in a small saucepan.

Recipe Notes

  • If using salted butter, reduce or omit the salt.
  • Don’t dump the warm chocolate in the middle of the mint layer and try to spread it over the entire pan.  It works better to add small amounts.  This way the warm chocolate doesn’t melt the mint layer.
  • Makes approx. 36 2 x 2-inch brownies
  • Brownies freeze very well for 2-3 weeks.  Layer cut brownies between waxed paper in a covered container. 
  • For a smaller batch of brownies, cut everything in the recipe by 1/2 and bake in a 9 x 13-inch baking pan.
