I always use springform cake tins when making no bake cheesecakes as they are easier when it comes to removing the cheesecake from the tin than loose-bottomed tins. Run a blunt knife around the edge of the tin. Next, unclip the springform mechanism slowly and lift off the tin. Transfer the cheesecake to a serving plate, removing the baking parchment from the biscuit base if you can do so.
