Hefekranz or Hefezopf are sweet breads from Switzerland, Germany, Austria and South Tyrol.
The dough is made from sugar, flour, butter, eggs and yeast.
Typically both Hefezopf and Hefekranz consist of three braided dough-pieces. While the Hefezopf is a loaf consisting only of a braid, the Hefekranz' braid is bent into a wreath.
Two similar kinds of bread called vetekrans and vetelängd are common in Sweden. From Wikipedia
