Pączki - although they look like berliners, bismarcks, and jelly doughnuts, pączki are made from especially rich dough containing eggs, fats, sugar and sometimes milk. They feature a variety of fruit and creme fillings and can be glazed, or covered with granulated or powdered sugar. Powidła (stewed plum jam) and wild rose hip jam are traditional fillings, but many others are used as well, including strawberry, Bavarian cream, blueberry, custard, raspberry and apple.
