Instructions

• Place 25 Oreo cookies in a large resealable plastic bag and crush with a rolling pin to fine crumbs, or pulse to crumbs in a food processor.
• Put the crumbs in a medium bowl, add 6 tablespoons melted butter, and stir with a fork until the crumbs are evenly moistened. Press the mixture into the bottom and up the sides of a 9-inch pie plate to form a crust. Chill in the refrigerator while you make the fillings.
• Reserve 1 ounce of the 4 ounces semi-sweet baking chocolate for shavings and set it aside. Chop the remaining 3 ounces of chocolate.
• Melt the chopped 3 ounces of chocolate in a medium bowl according to package directions: microwave in short intervals, stirring every 30 seconds, or melt over a double boiler, until smooth.
• Stir half of the 14-ounce can of sweetened condensed milk into the melted chocolate until smooth. Stir in 1 teaspoon vanilla extract. Let the chocolate mixture sit a few minutes, stirring occasionally to keep it spreadable.
• In a separate medium bowl, combine the remaining half of the sweetened condensed milk with 1/2 cup peanut butter and 1 teaspoon vanilla extract. Stir until smooth and uniform.
• In a chilled mixing bowl, whip 2 cups cold heavy whipping cream on high speed until it begins to thicken. Add 3 tablespoons powdered sugar and the remaining 1 teaspoon vanilla extract, then continue whipping to stiff peaks.
• Gently fold 1 cup of the whipped cream into the peanut butter mixture until combined but still light. Spread this peanut butter layer evenly into the prepared crust.
• Stir the chocolate mixture until smooth again. Gently fold 1 cup of the whipped cream into the chocolate mixture until combined and light. Spread the chocolate layer evenly over the peanut butter layer.
• Spread the remaining whipped cream over the top of the pie. Use a potato peeler on the reserved 1 ounce of chocolate to make shavings and sprinkle them over the whipped cream.
• Chill the pie in the refrigerator for at least 4 hours or overnight before slicing. Store loosely covered in the refrigerator and eat within 3 days.
