Grease the inside of the 8 or 9 inch springform pan with nonstick cooking spray and line the bottom of the pan with parchment paper. Wrap the outside of the pan with two layers of aluminum foil and bring the foil up the sides of the pan and make sure it’s tight and secure no water gets in during the baking process!!! (You can place springform pan in slightly larger pan before place it in the water bath, so you won’t have to use foil))
Preheat oven to 350 F.
Mix together Oreo crumbs and melted butter, press the mixture into the bottom of springform pan and smooth to get an even layer, set aside.
