1. Preheat your oven to 350°F (175°C). Combine chocolate cookie crumbs and melted butter in a bowl, mixing until well combined.
2. Press the mixture firmly into the bottom and up the sides of a 9-inch pie pan. Bake for 10 minutes, then let it cool completely.
3. In a large bowl, beat the peanut butter and cream cheese together until smooth. Gradually add powdered sugar, mixing until fully incorporated.
4. In a separate bowl, whip the heavy whipping cream until stiff peaks form. Gently fold the whipped cream into the peanut butter mixture until smooth and fluffy.
5. Spread the peanut butter filling evenly into the cooled crust. Refrigerate for at least an hour to set.
6. To make the chocolate ganache, heat 1/2 cup of heavy cream in a small saucepan until it begins to simmer. Remove from heat and pour over the chocolate chips.
7. Let it sit for a minute, then stir until smooth and glossy. Stir in vanilla extract and a pinch of salt.
8. Pour the ganache over the chilled peanut butter layer, spreading evenly. Return to the refrigerator for at least 2 more hours, or until fully set.

Remember, patience is key here—allowing each layer to set properly ensures the pie slices cleanly and looks as beautiful as it tastes.
