This recipe is foolproof, so sinking should not be an issue. That said, there are two important tips to keep in mind. Use room temperature ingredients so they incorporate well. An inconsistent batter can cause sinking. Be careful not to overmix or overwhip your batter. You might accidentally incorporate too much air into the filling and when those bubbles pop in the oven, the cheesecake can sink. However, it would take a lot of mixing for this to be an issue, so it’s highly unlikely!
