This uses a 1/2 c Kahlua liquer in the topping! It sounds so delicious. It comes from "The Joy of Cookies" by Sharon Tyler Herbst. The author suggests using pecans in place of the coconut if you are not a fan of coconut. Prep time is a guess. Some ingredients are listed more than once and in different quantities because the first time is for the cookies base, and the second is for the topping.
