Spoon half of the biscuit crumbs onto the base of the prepared tin. Use a glass to press the mixture down evenly. Press the remaining half of the mixture firmly up the sides of the pan
Place the the tin onto a baking tray and bake for 1 ¼ hours or until just set in the centre. Do NOT open the oven during the cooking time or the cheesecake will crack and sink. Turn the oven off and leave the cheesecake in the oven with the door closed for 2 hours.
After a minimum of 4 hours in the fridge (preferably overnight), carefully remove the cheesecake from the baking tin and remove the baking paper. Allow to come to room temperature for 1 hour before serving.
