Add the oreos to a food processor and pulse until fine crumbs form. Add the melted butter and salt and pulse until combined and completely moistened.
2 cups oreo cookie crumbs, 6 tablespoons unsalted butter, ¼ teaspoon kosher salt
Transfer to a 9” pie plate and press it in firmly up the sides and on the bottom. Freeze while you prepare the filling.
In the bowl of a stand mixer fitted with the whisk attachment (or with a hand mixer), whip the heavy whipping cream on medium low speed for one minute, then increase to high speed and whip until stiff peaks form. Transfer to another bowl.
1 cup heavy whipping cream
In the stand mixer bowl fitted with the paddle attachment, cream together the cream cheese and peanut butter until smooth. Add the sweetened condensed milk, powdered sugar and vanilla and mix until fully combined and thick.
8 oz cream cheese, 3 oz sweetened condensed milk, 1 cup creamy peanut butter, 1 ¼ cups powdered sugar, 1 teaspoon vanilla extract
Add half of the whipped cream and mix on low speed then scrape down the sides. Add the second half of whipped cream and fold it into the filling by hand to keep as much air as possible. Add the filling to the pie crust and spread evenly. Refrigerate for at least 4 hours.
While the pie sets, mix together the oreo crumbs, 2 tablespoons powdered sugar, peanut butter, and salt until crumbles form. Set aside.
½ cup oreo crumbs, 3 tablespoons creamy peanut butter, ¼ teaspoon kosher salt, 2 tablespoons powdered sugar

1 cup heavy whipping cream, ¼ cup powdered sugar, 1 teaspoon vanilla extract
Add the oreo peanut butter crumbles to the top of the peanut butter filling, then add the whipped cream. Top with chopped peanut butter cups and serve.
