Stollen is a fruit bread of nuts, spices, and dried or candied fruit, coated with powdered sugar or icing sugar and often containing marzipan. It is a traditional German Christmas bread. During the Christmas season the cake-like loaves are called Weihnachtsstollen or Christstollen. A ring-shaped stollen made in a Bundt cake or Gugelhupf pan is called a Stollenkranz. From Wikipedia
