A Bismark donut is a type of jelly-filled donut that was popular in Europe and found its way to America by the end of the 19th century. It is a premium and decadent donut that includes more dough, filling, and topping due to its rectangular shape. Depending on the location, the name and build of this donut may vary. In the Northeast, it can be similar to a Boston Kreme with chocolate icing and Bavarian Kreme filling, resembling an Éclair. At Bismarck Doughnuts and Beignets, they use a traditional yeast recipe to create all of their raised yeast doughnuts, including the Bismark donut. The Bismark donut is filled with various house-made creams, jams, and custards. It can also be filled with pastry cream or fruit-based pastry fillings.
