Prepare the Crust: In a medium mixing bowl, combine the finely crushed Oreo cookies and melted butter. Stir until the mixture is well-coated. Press this mixture firmly into the bottom and sides of a 9-inch pie dish to form a solid crust. Place the crust in the refrigerator to set while you make the filling.
Mix the Peanut Butter Filling: In a large mixing bowl, using an electric mixer, beat the creamy peanut butter and softened cream cheese together on medium speed until the mixture is smooth and creamy. Gradually add the powdered sugar while continuing to mix until everything is thoroughly combined and there are no lumps.
Whip the Cream: In a separate mixing bowl, use a hand mixer or stand mixer to whip the heavy cream on high speed until stiff peaks form. This should take about 2 to 3 minutes. Once whipped, gently fold the whipped cream into the peanut butter and cream cheese mixture using a spatula, being careful not to deflate the whipped cream. Continue folding until the mixture is well blended and light and airy.
Assemble the Pie: Carefully pour the creamy peanut butter filling into the prepared Oreo crust. Use a spatula to spread the filling evenly, ensuring it reaches the edges of the crust.
Melt the Chocolate: In a microwave-safe bowl, heat the semi-sweet chocolate chips in 30-second intervals, stirring well in between each interval until the chocolate is completely melted and smooth. Once melted, drizzle the warm chocolate over the peanut butter filling in a lovely decorative pattern, or you can create swirls if desired.
Chill: Cover the pie with plastic wrap or foil and refrigerate for at least 4 hours, or until it is completely set and firm to the touch.
Serve: Just before serving, drizzle chocolate syrup over the top of the pie and sprinkle with extra Oreo crumbs for an added crunch. Slice the pie into wedges and serve chilled. Enjoy the decadent flavors!
Notes
Serve slices on decorative plates, and consider adding a dollop of whipped cream on top of each slice for an extra indulgent touch!
