CRUST:
1. Start by placing the Oreo cookies in a food processor and blend until they become fine, even crumbs.
2. While the food processor is running on low, slowly pour in the melted butter until well combined. Press this delightful crumb mixture firmly into the base and slightly up the sides of a greased 9-inch pie dish. Pop it into the freezer for about 20 minutes to chill while you prepare the filling.
FILLING:
3. In a large mixing bowl, combine the softened cream cheese, creamy peanut butter, and confectioners' sugar. Beat them together with an electric mixer until the mixture is beautifully smooth and creamy.
4. Gently fold in the chopped Butterfinger candy bars, ensuring they are well distributed throughout the creamy mixture.
5. Carefully fold in the thawed whipped topping until just combined. You want to keep that light and airy texture!
ASSEMBLE & CHILL:
6. Spoon the luscious filling into your chilled Oreo crust, spreading it out evenly with a spatula. Then, place the pie in the refrigerator for at least 4 hours to set up perfectly.
7. Once thoroughly chilled and firm, remove your magnificent pie from the refrigerator. For an extra touch of deliciousness, garnish with additional whipped topping and a sprinkle of chopped Butterfingers just before serving. Slice and enjoy your homemade treat!
