Ingredients

Brownie Ingredients

  • 1/2 cup butter
  • 1/2 cup oil
  • 2 cups granulated sugar
  • 4 eggs
  • 2 teaspoons vanilla
  • 1/4 teaspoon mint extract
  • 2/3 cup cocoa powder
  • 1 cup all purpose flour
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking powder

Mint Buttercream Ingredients

  • 1/2 cup butter softened
  • 1 3/4 cups powdered sugar
  • 1-2 tablespoons heavy cream or milk
  • 1/4 to 1/2 teaspoon mint extract
  • a few drops green food coloring

Chocolate Ganache Ingredients

  • 1 cup heavy cream
  • 8 ounces bittersweet chocolate

Instructions

To Make The Brownies

  • Preheat oven to 350°F. Grease and flour a 9 x 13 inch pan or line with parchment paper. Melt the butter in a large microwave-safe bowl. Whisk in the oil, sugar, eggs, vanilla, and mint extracts. Add the cocoa, flour, salt, and baking powder. Mix well to combine.
  • Spread in the prepared pan and bake for 22-25 minutes or until an inserted toothpick comes out with a few crumbs. Let cool completely.

To Make The Mint Buttercream

  • To make the mint buttercream layer, beat the butter in a stand mixer for 1-2 minutes, beat in the powdered sugar. Add enough of the milk or cream to be a spreadable consistency and the mint extract to your tastes. Spread on top of completely cooled brownies and refrigerate.

To Make The Ganache

  • For the chocolate ganache, finely chop the chocolate and place in a heat proof bowl. In a heavy saucepan, bring the heavy cream to a simmer. Do not let it boil. Pour the whipping cream over the chopped chocolate and whisk until smooth.
  • Pour the ganache over the mint layer and refrigerate until set. Cut into squares.
