If you’re using a store-bought pie crust, simply follow the instructions on the package. If you’re making your own, ensure that it is fully cooled before proceeding.
In a mixing bowl, add the softened cream cheese. Using an electric mixer, beat it until it’s creamy and free of lumps. This should take about 2 minutes on medium speed.
Next, add in the peanut butter, sugar, and vanilla extract to the cream cheese. Mix well until all ingredients are combined and the mixture is smooth.
Gently fold in the Cool Whip using a spatula. Be careful not to deflate the mixture; you want to keep it light and airy.
Once the Cool Whip is fully incorporated, fold in the chopped Butterfinger candy bars. This adds that delightful crunch and flavor to your pie.
Spoon the filling into your prepared pie crust, spreading it evenly with a spatula.
Cover the pie with plastic wrap and refrigerate for at least 4 hours, or overnight if possible. This allows the flavors to meld beautifully.
When you're ready to serve, slice the pie into wedges and enjoy the creamy, crunchy goodness!
