Tip 1: Letting your cream cheese reach room temperature before making the cheesecake will help avoid air bubbles in your cheesecake and ensure even mixing. Tip 2: Place a pan filled with water on the oven shelf below your cheesecake. Adding water to the oven will help prevent your cheesecake from cracking. Tip 3: DON'T open the oven while the cheese cake is cooking or cooling. As tempting as it may be, opening the door will cause a quick change in temperature which can cause your cheesecake to crack.
