Step 1: Prepare the crust

Preheat oven to 350°F (175°C).

In a bowl, mix chocolate cookie crumbs, melted butter, and sugar until evenly combined.

Press mixture into the bottom and sides of a 9-inch pie dish.

Bake for 8 minutes, then let cool completely before filling.

Step 2: Make the chocolate filling

Warm the heavy cream in a small saucepan until steaming (do not boil).

Pour over the chocolate chips and let sit for 2 minutes. Stir until smooth and glossy.

In another bowl, beat cream cheese and sugar until smooth, then add vanilla.

Mix in melted chocolate until combined.

Gently fold in whipped topping to make a fluffy filling.

Step 3: Prepare the peanut butter swirl

In a bowl, whisk peanut butter, powdered sugar, and milk until smooth.

Adjust milk for a pourable but thick texture.

Step 4: Assemble the pie

Spread the chocolate filling evenly into the cooled crust.

Drop spoonfuls of the peanut butter mixture on top.

Use a knife or skewer to gently swirl the two together to create a marbled pattern.

Step 5: Chill and set

Cover the pie with plastic wrap.

Refrigerate for 4 hours, or overnight, until firm.

Step 6: Garnish and serve

Add chocolate shavings, crushed peanuts, or drizzles before serving.

Slice with a warm, clean knife for neat cuts.
