A cinnamon roll is a European and American pastry typically served drenched in an icing. It consists of a long string of bread rolled into a circular shape, with added cinnamon, as the name suggests. The icing consists of cream cheese,
vanilla,
sugar, and
butter. It can be poured on the cinnamon roll, or if you're mentally insane, you can dip the cinnamon roll into a cup of icing.
