A no-bake Oreo crust is topped with a super creamy, silky smooth peanut butter filling made from scratch (no Cool Whip!). Serve it chilled and drizzled with peanut butter and chocolate; it will be a family favorite for years to come!
Make the Crust: Process the Oreo cookies in a food processor until fine crumbs. Turn the crumbs out into a medium bowl. Add the melted butter and toss with a fork until all of the crumbs are moistened. Press into the bottom and up the sides of a 9-inch pie plate. Refrigerate for at least 30 minutes.
Make the Filling: Using an electric mixer, beat the cream cheese and powdered sugar on medium speed until light and fluffy, about 2 minutes. Add the peanut butter and vanilla and beat again until completely combined.
In a separate bowl, whip the heavy cream on medium-high speed until soft peaks form.
Using a rubber spatula, stir 1/3 of the whipped cream into the cream cheese mixture to lighten it up. Use a rubber spatula to gently fold in the remaining whipped cream. Transfer the filling to the chilled crust and spread in an even layer. Freeze uncovered for at least 4 hours or up to 1 day covered with plastic wrap.
Garnish the Pie: Put the chocolate in a microwave-safe bowl and heat in 30 second increments at 50% power, stirring after each. Continue until the chocolate is melted and smooth. Transfer to a resealable plastic bag and snip a tiny bit off the corner. Hold the bag over the pie and drizzle the melted chocolate in a zig-zag pattern. Melt the peanut butter in the microwave using the same method used for the chocolate. Add the melted peanut butter to a resealable plastic bag, snip off a corner and drizzle over the pie. Let stand for about 10 minutes to set. Return to the freeze if not serving immediately.
Remove the pie from the freezer about 10-15 minutes before you are ready to serve. If you have trouble cutting it, running your knife under warm water will help. Cover leftovers tightly with plastic wrap and foil, and store in the freezer.
