Prepare the crust by using a pre-made graham cracker pie crust or making your own by crushing graham crackers and mixing with melted butter and sugar, then pressing into a pie dish and baking for 8-10 minutes.

In a large mixing bowl, combine creamy peanut butter, powdered sugar, softened cream cheese, and vanilla extract. Beat on medium speed for 2-3 minutes until smooth.

In a separate bowl, whip heavy cream until stiff peaks form. Gently fold the whipped cream into the peanut butter mixture until combined.

Spoon the filling into the prepared crust and smooth the top. Cover with plastic wrap and refrigerate for at least 4 hours or overnight.
