What do you do to test the doneness of cakes?

To test the doneness of cakes, insert a toothpick or a cake tester into the center; if it comes out clean or with a few moist crumbs, the cake is done. Alternatively, gently press the top of the cake with your finger; if it springs back, it's ready. Additionally, check for a golden-brown color and a slight separation from the edges of the pan.
