Time and Tools. The most obvious difference between a cake and a cupcake is size, which depends on the container in which the dessert is prepared. Cakes are baked in large pans, usually round or square, and take half an hour or more to bake fully. Cupcakes, on the other hand, are baked in tins with several cups. Each cup is much smaller than a large cake pan, so a batch of cupcakes usually takes only about 15 minutes to bake.
