1. A spongy cake that is yellow in color, due to the use of egg yolks. It is often frosted and served at birthday parties. Do we have any yellow cake mix? I think I want a yellow cake for my birthday—I'm not in the mood for chocolate right now.
2. Uranium oxide powder that is produced by the milling of uranium ore. Often spelled as one word. Yellowcake can be used in the making of nuclear weapons, so its trade is heavily scrutinized.
