The term 'Cake with its own pan' can be summarized as a Bundt cake. A Bundt cake is a type of cake that is baked in a special ring-shaped pan, giving it a distinctive shape. It is usually made with a rich, buttery batter and often has a glaze or frosting. The Bundt pan was invented by a Minnesota-based company in 1950, and the cakes have become popular in the United States and around the world.
