When making this no bake cheesecake, I always line the baking pan with parchment paper. When doing this, make sure you allow the ends of the parchment paper to overlap the sides of the pan! That way, you can easily lift the cheesecake out of the pan once it's set. If you're all out of parchment paper, though, that's okay. There's no need to spray nonstick oil to the bottom of the pan, as you won't be baking the crust.
