A Winter-Baking Idea from Dr. Oetker: This Cinnamon Gugelhupf is a classic wintry flavor experience in the run-up to Christmas. The finely measured cinnamon note and the delicious cinnamon glaze in a trendy "drip look" go perfectly with the fluffy sponge cake. The Gugelhupf is prepared quickly and easily. just add butter, eggs and milk.  Ideal for enjoying together in the cold season - only in limited quantity and for a short time!
