Grasshopper brownies

Recipe found online

Ingredients
Brownies:
2 boxes brownie mix

Mint Frosting:
4 cups powdered sugar
1 cup soft butter
2 Tbsp. water
1 1/2 tsp. peppermint extract
4 drops green food coloring

Chocolate Topping:
12 ounces semisweet chocolate chips
3/4 cup butter

1) To make the Brownies follow the recipe for "cake-like" brownies. Or if their isn't one, use 3 eggs. Pour into a large, greased cookie sheet, bake and let cool completely. (I baked them on a jelly roll pan, which is why they are so thick).
2) To make the mint frosting, combine powdered sugar, butter, water, peppermint extract and food coloring. Mix. Spread over cooled brownies and refrigerate until hard on top.
3) To make chocolate topping microwave chocolate chips and butter for 2 minutes. Stir until all chocolate chips are melted and the mixture is smooth. Add 1-2 tsp. peppermint extract. As soon as this mixture thickens and is no longer hot, spread over mint topping on brownies. Put back into the refrigerator until hard.
4) Enjoy! This batch feeds a lot by the way.
