Make 1 boxed or homemade brownie mix according to directions. Pour about half of the batter into the bottom of a greased spring-form pan (this is if your recipe makes a 9x13 pan, if your recipe only makes an 8x8 then pour it all in.) Use the rest of the batter for a pan of 8x8 brownies.
Bake the brownies until done. Let cool completely in the pan.
Filling:
8 oz Cream Cheese
3/4 cup sugar
1/2 tsp mint extract
green food coloring
8 oz tub of Cool Whip
Cream together the cream cheese and sugar, add mint extract and food coloring. Fold gently into cool whip. Pour into spring-form pan on top of cooled baked brownie. Either drizzle the top with melted chocolate or better yet, just sprinkle chocolate chips on top. Let set up in fridge or stick it in the freezer for several minutes to firm up, just don't let it freeze.
Take off the side of pan, slice into pie wedges and enjoy!!!
