When cooking the cheesecake, make sure to allow your cheesecake to cook for at least 45 minutes. Cooking time will vary, but I recommend not opening the door to prevent the cheesecake from cracking for at least 40 to 45 minutes. Once this time has been reached, give the cheesecake pan a little nudge to see if the center jiggles. The edges might be pulling aware from the pan and become brown but it is all about the center. There should be a slight jiggle at the center of the cheesecake when you know it is done. As it cools, the cheesecake center will firm up to be a solid piece of cheesecake.
