I’m an avid baker, when cheesecakes crack it’s beciase the oven is too dry, you can avoid this by placing a water bath beneath the cheesecake (just make sure no water leaks into the cake tin) or u can place an ovenproof bowl/mug filled with water into the oven beside the cake.
When the cheesecake is finished open the oven a crack first and let it sit for 20 mins then take out of oven 👍
