Experience the magic of a perfectly made peanut butter pie. This pie is creamy, rich, and filled to the brim with peanut butter. It's sure to be a hit!
Preheat oven to 350°F. Grease the sides and bottom of a 9-inch pie plate.
Crush the Oreos in a food processor or blender until finely ground. Transfer to a mixing bowl. Combine with melted butter until crumbs are moistened. Press the mixture into the bottom of the prepared pie pan. Bake for 8-10 minutes.
In a bowl, combine 1/2 cup peanut butter and 1/4 cup butter. Melt in the microwave for about 30 seconds or until the mixture becomes more fluid. Mix in 1/4 cup powdered sugar until well combined. Pour this mixture onto the warm crust. Allow the crust to cool completely.
In a large mixing bowl, combine heavy cream, 1/2 cup powdered sugar, and dry milk powder. Beat on high until stiff peaks form using a hand mixer or stand mixer.
In a separate bowl, mix the remaining 1 cup peanut butter with the remaining 1/4 cup powdered sugar until smooth.
Gently fold the peanut butter mixture into the whipped cream until evenly blended.
Spread the mixture into the cooled pie crust. Refrigerate until set, at least 6 hours. Drizzle with chocolate syrup and add your preferred toppings before serving cold.
