Some other cruller styles are made of a denser dough somewhat like that of a cake doughnut formed in a small loaf or stick shape, but not always twisted. Crullers may be topped with plain powdered sugar; powdered sugar mixed with cinnamon; or icing. However, a French cruller is a fluted, ring-shaped doughnut made from choux pastry with a light airy texture. The French cruller in German is called a Spritzkuchen. 1 History and origin.
