If you’re baking cakes in a toaster oven, it’s difficult to determine the exact time and temperature for your specific oven, as it depends on its type and size. In general though, cakes require medium heat and are rendered ready when a toothpick inserted in the center of the cake comes out clean. Be sure to use the upper and lower heating sources and to bake your cakes on the middle rack. It might take a few trials until you learn your oven, so don’t get upset or give up without giving yourself another chance to turn a failure into something fabulous!
