A Gugelhupf cake pan with a diameter of 28 cm is a specialized baking tool designed to craft traditional European-style ring cakes, also known as Gugelhupf or Bundt cakes. These pans are typically made from high-quality materials like heavy-duty aluminum or feature a non-stick coating, which ensures even heat distribution and easy release of the cake. The distinct design of the Gugelhupf pan includes fluted sides and a central tube, which creates a hole in the middle of the cake, facilitating uniform baking and making the cake easier to slice.
