Kougin-amann (pronounced [ˌkwiɲ aˈmãn]; pl. kouignoù-amann) is a Breton cake. The name comes from the Breton language word for cake (kouign) and butter (amann). It is a round multi-layered cake, originally made with bread dough containing layers of butter and sugar folded in, similar in fashion to puff pastry albeit with fewer layers. The cake is slowly baked until the butter puffs up the dough (creating the layers) and the sugar becomes caramelized. The result is similar to a muffin-shaped, caramelized croissant.
Kouign-amann is a specialty of the town of Douarnenez in Finistère, Brittany, where it originated around 1860.
