A bundt cake is a cake baked in a ring-shaped pan with a central hole, called a bundt pan, which gives the finished cake its fluted ring shape and a dense, moist, evenly baked crumb. The pan was developed and trademarked by Nordic Ware in 1950, inspired by the traditional European gugelhupf, though bundt cake recipes -- usually a butter or pound cake batter -- differ from that yeast-leavened original. Common flavors include chocolate, lemon, and cinnamon, and the cake is often finished with a glaze, powdered sugar, or a filling such as fruit compote or cream cheese in the center hole.
