Stollen is a German traditional oblong-shaped baked bread (Gebäck) for Christmas. It is made from heavy or rich yeast/leavened dough with butter, sugar, eggs and a bit of salt. It is spiced with cinammon (zimt), nutmeg (muskat), with grated almonds and raisins (Rosinen) and candied dried fruits (Trockenfructen) and drizzeled with powdered sugar. Some versions are filled with Marzipan or Poppy seeds (Mohn) at the center.
Stollen is also called Christstollen or Weinachtsstollen.
