For the Brownies
  • 4 ounces unsweetened baking chocolate
  • 1 cup butter
  • 4 large eggs
  • 2 cups granulated sugar
  • 1 teaspoon vanilla extract
  • 1 1/4 cups all-purpose flour
  • 1/2 teaspoon baking powder
For the Mint Frosting
  • 2 cups powdered sugar
  • 4 Tablespoons butter , room temperature
  • 1 1/2 teaspoons peppermint extract
  • 1-2 Tablespoons milk
  • green food coloring
For the Chocolate Glaze
  • 6 ounces semi-sweet chocolate chips (about 1 cup)
  • 5 Tablespoons butter
For the Brownies:
  1. Preheat oven to 350 degrees F. Grease a 9×13'' inch pan with nonstick cooking spray.

  2. Chop the butter and the unsweetened chocolate into chunks and place together in a microwave safe bowl. 

  3. Microwave on low power in 30 second intervals, stirring in between, until melted. (You could also melt them over LOW heat in a saucepan, stirring constantly). Set aside to cool, stirring occasionally.

  4. In a large bowl beat together the eggs, sugar, and vanilla.  Slowly add the melted chocolate, while stirring.

  5. In a separate small bowl combine the flour and baking powder. Stir the flour into the chocolate batter, just until combined. Don't over-mix.

  6. Pour batter into greased pan and bake for 20-30 minutes or until a toothpick inserted in the center comes out clean.

  7. Remove from oven and allow to cool completely.
For the frosting:
  1. Combine all frosting ingredients and beat until light and fluffy. Add more milk if you want it thinner. 

  2. Spread the frosting evenly over the cooled brownies. Refrigerate while you make the chocolate glaze.

For the Chocolate Glaze:
  1. Place chocolate chips and butter in a microwave safe bowl. Microwave one low power in 30 second intervals, stirring in between, until melted and smooth. Allow to cool for about 5-10 minutes. 

  2. Spread evenly over the frosted brownies. Return to fridge to allow the chocolate to harden.

  3. Allow the bars to sit at room temperature for 10 minutes before cutting into squares. (If you try to cut into them while they are cold the top chocolate layer will crack pretty easily and they wont be as pretty).
