A semla is a traditional pastry made in various forms in Finland, Sweden, Latvia, Norway, Denmark and Estonia. Semlor is the plural of semla.

Today, the Swedish-Finnish semla consists of a cardamom-spiced wheat bun which has its top cut off and insides scooped out, and is then filled with a mix of the scooped-out bread crumbs, milk and almond paste, topped with whipped cream.

The cut-off top serves as a lid and is dusted with powdered sugar. Today it is often eaten on its own, with coffee or tea. Some people still eat it in a bowl of hot milk. In Finland, the bun is sometimes filled with strawberry jam instead of almond paste, and bakeries in Finland usually offer both versions. (Many bakeries distinguish between the two by decorating the traditional bun with almonds on top, whereas the jam-filled version has powdered sugar on top).
