Begin by taking one package of Oreos and placing them in a food processor. Pulse until the Oreos become a fine crumb texture. Next, add melted butter to the crumb mixture and blend again.

Transfer the Oreo and butter crumb mixture into a pie dish, making sure to evenly spread it along the bottom and up the sides to create a pie crust. Use a spoon to compact the mixture. Let the dish rest in the fridge for approximately 30 minutes to allow it to set.

Now, place the second package of Oreos into the food processor, and keep a few Oreos for decorating the top. Blend the remaining Oreos into a crumb then mix it with whipped cream and mix thoroughly.

Gently pour the cream and Oreo mixture into the set pie crust. Spread it out and decorate it with the whipped cream in the piping bag and a few Oreo crumbs.
