Before attempting to remove it from the springform pan, be sure the cheesecake has been chilled in the fridge for at least overnight. The key here is to make sure the cream cheese layer has been in the fridge long enough to set completely. Undo the lock on the pan, and remove the sides. Using a sharp knife or metal spatula, gently place between the Oreo crust and the pan to loosen. Then use a couple of large spatulas under the Oreo crust to place the cheesecake onto a serving plate.
