Place the dough on a sheet pan lined with parchment paper with the seams facing down. Connect the ends of your cake, creating a ring. It is okay if it does not look perfect; the icing will cover any imperfections. Place a glass cup in the middle to prevent the inside from touching.
Loosely cover the top of the cake with foil to prevent additional browning, and bake the cake for another 30 minutes. It should be an attractive golden brown on the top.
