You can check to make sure a toothpick comes out clean but I check most bread and cakes by touch. Once you get the hang of it, I find it to be a little more reliable than the toothpick test. First, I jiggle the pan to see if there is any jiggle in the bread. If there is, give it 10 more minutes. Secondly, I press my finger tips very gently in the center. If the center feels spongy and springy, the cake is done.
