In a medium bowl, combine graham cracker crumbs and melted butter until well mixed. Press this mixture firmly into a pie dish to form an even layer that will serve as the base of your pie.
Blend softened cream cheese in a mixing bowl until smooth and creamy. Gradually mix in peanut butter and confectioners' sugar until everything is well combined and has reached a delightful consistency.
Spread the luscious cream cheese mixture evenly over your prepared crust using a spatula to ensure it’s flat and even across the surface.
In a chilled mixing bowl, beat heavy whipping cream until soft peaks begin to form. Slowly add cocoa powder, continuing to whip until stiff peaks form, creating a fluffy chocolate topping.
Generously spread or pipe the chocolate whipped cream on top of your filled pie, decorating it as desired for added visual appeal.
Refrigerate your pie for at least four hours or overnight to allow it to set completely before serving, ensuring every slice holds its shape beautifully.
