Prepare the Oreo Crust: Place 18 Oreos in a food processor and pulse until finely crushed. Add melted butter to the crumbs and pulse again until the mixture is well combined. Press the mixture into the bottom of a 9-inch springform pan or a pie dish to form a crust. Refrigerate while you prepare the filling.
Make the Cheesecake Filling: In a large mixing bowl, beat the softened cream cheese and powdered sugar until smooth and creamy. Add vanilla extract and mix well.
Whip the Cream: In a separate bowl, beat the heavy cream and ¼ cup powdered sugar until stiff peaks form.
Combine the Filling: Gently fold the whipped cream into the cream cheese mixture until smooth and well combined.
Assemble the Cheesecake: Pour the cheesecake filling over the chilled Oreo crust. Use a spatula to smooth the top.
Chill: Cover the cheesecake with plastic wrap and refrigerate for at least 4 hours, or overnight for the best results.
Add Toppings: Once the cheesecake is set, crush the remaining 6-8 Oreos and sprinkle them over the top for garnish.
Serve: Slice and serve chilled. Enjoy!
