What Is a Bismarck Doughnut?
A Bismarck is a type of filled pastry that resembles a doughnut without a hole. Also known as a Berliner, Bismarcks are typically made of yeast dough fried in lard, filled with fruit jam and topped with a dusting of powdered sugar or a drizzle of icing glaze.
According to Leite's Culinaria, Bismarcks, known as "Bismarcken" in Germany where the nickname originated, were a favorite snack of Chancellor Otto von Bismarck, who was responsible for uniting Germany following a series of wars in the mid-1800s. German immigrants who entered the United States in the early 1900s brought the recipe and terminology with them, and filled doughnuts are still commonly referred to as Bismarcks, particularly in the Midwest.
