Yellow cake is a type of cake known for its rich, buttery flavor and vibrant yellow color. It is typically made with ingredients like flour, sugar, eggs, butter, and baking powder. The yellow hue comes from the use of egg yolks, which contribute to both the color and moisture of the cake. Yellow cake is often used as a base for layered cakes and is popular for celebrations. In addition to its culinary meaning, "yellow cake" can also refer to a form of uranium concentrate used in the nuclear industry. This powdery substance is produced during the processing of uranium ore and is an intermediate step in the production of nuclear fuel. While both meanings share the same name, they are entirely different in context and application.
