To make the crust, crush your cookies in a food processor until they are fine crumbs (you can also put the cookies in a gallon-sized resealable bag and crush with a rolling pin).
Dump the cookie crumbs into a bowl and mix with melted butter.
Press the cookie mixture into the bottom of a 9" pie pan, making sure to go up the sides of the pan.
Place crust in the fridge and let chill for at least 30 minutes before adding filling.
To make the pie filling, beat the cream cheese and powdered sugar together in a large bowl. Add in the peanut butter and the vanilla, then mix again.
In a separate bowl, whip the heavy whipping cream (I used an electric mixer) until stiff peaks start to form. Fold the whipped cream into the peanut butter mixture until well-combined.
Pour peanut butter filling into the cookie crust and place in the freezer for at least 3 hours.
Remove pie from freezer about 10 minutes before you are ready to serve it to allow it to thaw just enough that you can easily cut it.
Top with chocolate chips and drizzle with chocolate sauce when serving.
Notes
Make sure to let pie Freeze for at least 3 hours to make sure it sets up properly.
