A cake pan is a kitchen tool used for baking cakes. It is typically made of metal, glass, or silicone and comes in various shapes and sizes, such as round, square, or rectangular. The pan provides a structure for the batter to rise and hold its shape while baking. Most cake pans have a non-stick coating to make it easier to remove the cake after baking. Some pans also have features like removable bottoms or decorative designs. Proper care and cleaning of a cake pan can extend its lifespan and ensure better baking results.
