Remove the cream centers from your Oreos and toss the cream - you don't need it for this recipe! In a zip lock bag, put all of your Oreo halves inside, zip tight, and pound them until they are most crushed. We left ours not so broken up. We liked the crumbled texture of the cookies!
Pour your crushed cookies in a a bowl along with your melted butter and combine thoroughly. Pour your cookie and butter mixture into a pie pan and press into the pie pan evenly to form a crust. Set your Oreo crust in the fridge and allow the crust to stiffen.
You'll be mixing 8 Fun Sized Butterfingers into the pie and setting aside 4 for the top. Crush your first 8 candy bars in a zip lock bag and set aside.
In a separate bowl, mix together your peanut butter, cream cheese, and sweetened condensed milk. Then, fold in your Coolwhip and 8 crushed Butterfingers and until combined.
Pull your set pie crust from your fridge. Pour your mixture in your pie pan.
Top your pie with the remainders 4, crushed Butterfinger candy bars.
Allow the pie to sit in your fridge for at least 2 hours to give it time to sit and stiffen.
Once your pie has been in your fridge for a few hours, cut into 8 equal slices and serve!
