The Danish New Year’s Eve dessert traditionally made with a ring-shaped form is kransekage.
Kransekage is a Scandinavian almond cake built from concentric rings of baked almond paste, sugar, and egg white. The rings are stacked to create a tall cone or tower and commonly decorated with white icing.
In Denmark, the cake is strongly associated with New Year’s Eve, where it is served with sparkling wine at midnight. It also appears at weddings, Christmas celebrations, and other major occasions. Individual pieces are cut from the stacked rings.
The name kransekage means “wreath cake” in Danish. A closely related Norwegian version is called kransekake. Although the two cakes share ingredients and construction, the Danish name is the relevant term for the Danish New Year custom.
