In a medium-sized bowl or a food processor, add the whole Oreo Cookies and blend until the texture of coarse meal or crumbs. Add the melted butter and blend just until well combine.
Place the ground crumb mixture into a 9- or 10-inch deep-dish pie pan and press onto the bottom and up the sides evenly. Try to make the crust about 1/8 inch (1/3 cm) evenly all around.
Refrigerate the crust for at least an hour before you add the filling of your choice. This will help prevent crumbling when you want to serve it.
* Use the whole cookie. Do NOT remove the filling from the cookies.
