The kransekake, which translates to "wreath cake", is the signature cake of Norway and a showstopping confection that is made for special occasions. And as impressive as a tall tower made out of eighteen delicate cookie rings is, this sweet stunner is surprisingly straightforward to make. The naturally gluten-free dough is made from processing almonds until finely ground, then confectioners' sugar and egg whites are added to bind it together. After an overnight rest, the dough is rolled into ropes and fitted into specialty molds. Once baked, the rings are stacked sky-high and kept in place with royal icing, which pulls double duty as both glue and garnish.
