This pie could not be easier because it literally takes less than 10 minutes to make.
Cream the cream cheese, peanut butter and sugar until smooth. Incorporate the whipped topping using a whisk to get a smooth consistency.
Pour into the pie crust. Chop up the peanut butter cups and sprinkle on top. Refrigerate the pie until ready to serve.
When ready to serve, slice the pie and drizzle with the caramel syrup.
