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
Preparation
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.
