A donut pan is a baking tool that is specifically designed to make donuts. It typically consists of a metal ring with several small wells, each shaped like a miniature version of a traditional donut hole. The pan allows you to easily create multiple donuts at once by placing batter into the individual wells and then baking them until they are cooked through. Once finished, the donuts can be removed from the pan in one easy step, leaving behind the metal ring for convenient storage or reuse.
