**Prepare the Crust**
- Crush the Oreos into fine crumbs using a food processor or by placing them in a zip-top bag and crushing them with a rolling pin.
- In a mixing bowl, combine the crushed Oreos with melted butter and mix until well combined.
- Press the mixture evenly into the bottom and up the sides of a 9-inch pie dish to form the crust. Refrigerate for 30 minutes.
**Make the Filling**
- In a chilled bowl, use an electric mixer to whip the heavy cream until stiff peaks form. Set aside.
- In another bowl, beat the cream cheese, powdered sugar, and vanilla extract until smooth and creamy.
- Gently fold the whipped cream into the cream cheese mixture until fully combined.
- Fold in the crushed Oreos.
**Assemble the Pie**
- Spread the filling evenly into the chilled crust. Smooth the top with a spatula.
- Decorate with Oreo halves or crushed Oreos and dollops of whipped cream as desired.
**Chill**
Refrigerate the pie for at least 4 hours, or until set. For best results, chill overnight.
**Serve**
Slice and serve chilled. Enjoy this rich and creamy Oreo delight!
