The best way to check if your cheesecake bars are done is to use the jiggle test. Here's how: Gently shake the cheesecake pan to see if it jiggles. The outer 1-2 inches should look set and firm, while the center should have a slight jiggle but not be liquidy. If the center wobbles slightly but is mostly set, the cheesecake is done. If the center still looks liquidy, bake for a few more minutes and check again.
