Prepare the Crust: Combine cookie crumbs and melted butter, press into a 9-inch pie dish, and refrigerate at least 20 minutes.
Make the Filling: Beat cream cheese until smooth, add peanut butter, powdered sugar, and vanilla, then fold in whipped topping gently.
Assemble Pie: Spoon filling into chilled crust and smooth top. Refrigerate briefly.
Prepare Chocolate Topping: Heat cream until steaming, pour over chocolate chips, let sit 1–2 minutes, stir until smooth. Cool slightly.
Final Assembly: Pour ganache over peanut butter layer, spread gently, add optional toppings, and refrigerate until fully set (4 hours minimum, overnight preferred).
Notes
Use room-temperature cream cheese for smooth filling.Chill crust and pie to help layers hold and slice cleanly.Ganache should be slightly cooled before pouring to avoid melting the filling.
