Everyone thought I bought it at the store, which I'm pretty sure was a compliment. Then, when they found out I actually made it, they all asked for the recipe! This recipe makes 2 pies, which is fine because you can just store the extra one in the freezer until you need it. Unfortunately, I don't have any left, so I guess I'll have just have to make it again! Here's the recipe, with my tweaks.
Easy No-Bake Peanut Butter Pie8 oz. cream cheese, softened (I used light)
1 1/2 cups confectioner's sugar
1 cup peanut butter
1 cup milk
2 prepared 9 inch Oreo pie crusts
2 16 oz containers whipped topping, thawed (I used light)
8 Reese's Peanut Butter Cups, chopped
Mix cream cheese and confectioner's sugar. Add peanut butter and milk and stir until smooth. Fold in 1 container of whipped topping. Divide the mixture into the two pie crusts, and put the pies in the freezer to set for at least 15 minutes. Then, top the pies with the remaining container of whipped topping and sprinkle with the chopped Reese's Peanut Butter Cups. Cover the pies and freeze them until you're ready to serve.
