Ingredients

  • Base:
  • 1 cup all-purpose flour
  • 1/2 cup butter, softened
  • 1/2 teaspoon salt
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1 (16-ounce) can chocolate-flavored syrup
  • 1 cup granulated sugar
  • Filling:
  • 2 cups confectioners' sugar
  • 1/2 cup butter, softened
  • 1 tablespoon water
  • 1/2 teaspoon mint extract
  • 3 drops green food coloring
  • Topping:
  • 1 (10-ounce) package mint chocolate chips
  • 9 tablespoons butter

Method

  • Base:
  • Pre-heat oven to 350 F. Combine the ingredients for the base in a large mixing bowl; beat at medium speed for 3 minutes. Pour batter into a greased 13 x 9 x 2-inch baking pan. Bake for 30 minutes (top of brownies will still appear wet). Cool completely.
  • Filling:
  • Combine filling ingredients in a medium mixing bowl; beat until creamy. Spread over cooled brownies. Refrigerate until set.
  • Topping:
  • Melt chocolate chips and butter over low heat in a small saucepan (then add mint extract, if using). Let cool for 30 minutes or until lukewarm, stirring occasionally. Spread over filling. Chill before cutting. Store in the refrigerator.
