Prep Time 20 minutes
Cook Time 1 hour 20 minutes
Total Time 1 hour 40 minutes


For the brownie layer:

  • 1/2 cup butter, cut into pieces
  • 4 ounces unsweetened chocolate, coarsely chopped
  • 1-1/4 cups granulated white sugar
  • 1 teaspoon pure vanilla extract
  • 2 large eggs
  • 1/2 cup all purpose flour
  • 1/8 teaspoon salt

For the mint layer:

  • 3 tablespoons butter, at room temperature
  • 1-1/2 cup powdered sugar
  • 1-1/2 – 2 Tablespoons heavy cream
  • 3/4 teaspoon pure peppermint extract
  • green food coloring (optional)

For the chocolate ganache:

  • 1/2 cup semi sweet chocolate chips
  • 1/4 cup cream


    Make the brownie layer:

    1. Preheat oven to 325F and place the rack in the center of the oven. Have ready a 9 x 9 inch square baking pan that has been lined with aluminum foil across the bottom and up two opposite sides of the pan. Set aside. (I used an 8×8 pan and all was well)

    2. In a stainless steel (heatproof) bowl placed over a saucepan of simmering water, melt the butter and chocolate.

    3. Remove from heat and stir in the sugar and vanilla extract. Add the eggs, one at a time, beating well after each addition. Stir in the flour and salt and beat, with a wooden spoon, until the batter is smooth and glossy and comes away from the sides of the pan (about one minute).

    4. Pour the brownie batter evenly into the prepared pan.

    5. Bake in the preheated oven for about 25 minutes or until the brownies start to pull away from the sides of the pan and the edges of the brownies are just beginning to brown. A toothpick inserted in the center of the brownies will come out almost clean. Remove from oven and place on a wire rack to completely cool.

    Make the mint layer:

    1. In the bowl of your electric mixer or with a hand mixer, beat all the ingredients until smooth. Add a few drops of green food coloring if you want the frosting green. If the frosting is too thick, add a little extra cream. (The frosting should be just thin enough to spread)

    2. Spread the frosting evenly over the cooled brownie layer. Place in the refrigerator for about 5-10 minutes or until firm.

    Make the chocolate ganache:

    1. In a heatproof bowl over a saucepan of simmering water, melt the chocolate and and cream.  Allow to cool about 15 minutes. 

    2. Spread over the mint filling and refrigerate for about 30 minutes.

    3. Remove the brownies from the pan by lifting with the ends of the foil and transfer to a cutting board. With a sharp knife, cut into squares. It is a good idea to wipe your knife between cuts with a damp cloth. These brownies can be stored in the refrigerator for several days or else frozen.


Your yield will depend on how big or small you cut your brownies.
