01 - Crush chocolate sandwich cookies into fine crumbs using a food processor or place in a resealable bag and crush with a rolling pin. Combine crumbs with melted butter until evenly moistened. Press mixture firmly into the bottom and up the sides of a 9-inch pie dish. Refrigerate while preparing filling.
02 - In a large bowl, beat together creamy peanut butter, softened cream cheese, and powdered sugar until completely smooth and creamy. Set aside.
03 - In a separate chilled bowl, whip cold heavy cream and vanilla extract until stiff peaks form. Be careful not to over-whip.
04 - Gently fold whipped cream into peanut butter mixture using a rubber spatula until just combined and smooth. Do not over-mix. Spread filling evenly into the chilled crust.
05 - Heat 1/4 cup heavy cream until steaming hot. Pour over chocolate chips in a small bowl and let sit for 2 minutes. Stir until chocolate is completely melted and ganache is smooth. Spread evenly over the peanut butter layer. Sprinkle with chopped peanuts if desired.
06 - Refrigerate pie for at least 4 hours or until completely set. The pie should be firm to the touch. Slice and serve chilled.
