In middle Germany, doughnuts are called "Kreppel" or "Pfannkuchen". In southern Germany, they are also called "Krapfen" and are especially popular during Carnival season ("Karneval"/"Fasching") in southern and middle Germany and on New Year's Eve in northern Germany. A "Berliner" does not have the typical ring shape of a doughnut, but instead is solid and usually filled with jam, while a ring-shaped variant called "Kameruner" is common in Berlin and eastern Germany. "Bismarcks" and "Berlin doughnuts" are also found in Australia, Canada, Denmark, Finland, Switzerland and the United States. Today, U.S.-style doughnuts are also available in Germany, but are less popular than their native counterparts.
