Take one package of Oreos and place the cookies 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.
Whip the cream with an electric mixer until it forms stiff peaks. Take out about 1 cup and place it into a piping bag to decorate the top.
Place the second package of Oreos into the food processor, but keep a few whole Oreos for decorating the top. Blend the remaining Oreos into a crumb, then mix it with whipped cream and mix thoroughly.
