The term 'Bundt' refers to a type of CAKE PAN that is shaped like a ring or a tube. The CAKE is usually baked in the PAN and then inverted onto a plate or platter for serving. The term 'Bundt' is derived from the German word 'bundkuchen, ' which means 'CAKE with a hole in the middle.' The most common Bundt CAKE is the classic yellow CAKE, but there are many variations. The PAN itself is usually made of cast aluminum or stainless steel and is available in a variety of sizes and shapes.
