Step 1: Prepare the Crust

1. Crush the Cookies: In a food processor, pulse the chocolate sandwich cookies until finely crushed. Alternatively, place the cookies in a zip-top bag and crush them with a rolling pin.
2. Combine with Butter: Transfer the cookie crumbs to a bowl and mix with melted butter until the mixture resembles wet sand.
3. Press into Pan: Firmly press the mixture into the bottom and up the sides of a 9-inch pie pan or springform pan. Use the back of a spoon or the bottom of a glass to smooth it out.
4. Chill the Crust: Place the crust in the refrigerator while you prepare the filling.

Step 2: Make the Peanut Butter Filling

1. Mix the Peanut Butter Base: In a large mixing bowl, beat the peanut butter, cream cheese, powdered sugar, and vanilla extract with a hand mixer until smooth and creamy.
2. Whip the Cream: In a separate chilled bowl, beat the heavy whipping cream until stiff peaks form.
3. Fold Together: Gently fold the whipped cream into the peanut butter mixture until no streaks remain. Be careful not to deflate the whipped cream.
4. Fill the Crust: Spoon the peanut butter filling into the chilled crust, spreading it evenly with a spatula.

Step 3: Prepare the Chocolate Ganache

1. Heat the Cream: In a small saucepan or microwave-safe bowl, heat the heavy cream until it’s just about to simmer (do not boil).
2. Melt the Chocolate: Place the chocolate chips in a heatproof bowl and pour the hot cream over them. Let sit for 2-3 minutes, then stir until smooth and glossy.
3. Cool Slightly: Allow the ganache to cool for 5-10 minutes before pouring it over the peanut butter filling.

Step 4: Assemble the Pie

1. Pour the Ganache: Gently pour the cooled ganache over the peanut butter filling, spreading it evenly to cover the top.
2. Chill: Refrigerate the pie for at least 4 hours or overnight to set completely.

Step 5: Garnish and Serve

1. Add Toppings: Before serving, decorate the pie with whipped cream, crushed peanuts, or your favorite candy toppings for added flair.
2. Slice and Enjoy: Use a sharp knife dipped in warm water for clean slices. Serve chilled.
