Layered Mint Chocolate Brownies

from the Worldwide Ward Cookbook

Brownie:
1 cup butter, melted
2/3 cup cocoa powder
2 cups sugar
4 eggs
1 1/2 cups flour

Mint Frosting:
1/2 cup butter, softened
1 pound powdered sugar
1-3 tablespoons milk
1/2 teaspoon mint extract
Green food coloring

Chocolate Topping:
1/2 cup semi-sweet chocolate chips
2 1/2 tablespoons butter

Brownie:
Mix butter, cocoa and sugar; add eggs, one at a time, beating well after each one. Stir in flour. Spread into a greased 9x13-inch pan. Bake at 350 degrees for 25 minutes. Let cool completely. (You can cover the pan and put it in the fridge to speed up the process.)

Mint Frosting:
Mix butter and powdered sugar. Add only enough milk to make a smooth consistency. Add mint extract and enough food coloring for a light green color. Frosting will be thick. Spread over brownie layer. Refrigerate until frosting is firm.

Chocolate Topping:
Melt chocolate chips and butter in microwave (1-3 minutes, depending on your microwave). Stir well to combine. Drizzle over frosted brownies. Refrigerate until topping is set.

Let brownies sit at room temperature for 10 minutes before cutting. Cut into 24 small squares with sharp knife.
