To prepare the crust, start by using a food processor to pulse the Oreo cookies into fine crumbs.

Next, add the melted butter and mix thoroughly.

Press this Oreo mixture into the pie pan to form an even crust, then freeze it for 10 minutes.

In the meantime, in a large mixing bowl, combine softened butter and peanut butter until well blended.

Add the vanilla extract and powdered sugar, mixing until smooth.

Spread the peanut butter mixture evenly over the chilled crust.

For the ganache, combine peanut butter, chocolate chips, and heavy whipping cream in a microwave-safe bowl.

Heat the mixture in 30-second increments, stirring each time until fully melted and smooth.

Pour the ganache over the peanut butter layer, spreading it out evenly.

Finally, chill the pie in the refrigerator for at least 4 hours, or overnight, to allow it to set.
