To prepare the crust: Crush 25 oreos with a rolling pin, heavy pot, or food processor. Combine with melted butter and press into 9 inch pie plate. Refrigerate for 20 minutes to harden.
In a large bowl, cream together peanut butter and cream cheese. Add powdered sugar and mix until smooth and creamy. Stir in whipped cream and mix until smooth and no lumps remain.
Pour filling into pie crust. Freeze for at least an hour.
Drizzle with hot fudge and crumbled candy bars and serve immediately. Store leftovers covered in the freezer.
