What Finnish oven-baked pancake is usually made in a sheet pan?

The Finnish oven-baked pancake usually made in a sheet pan is pannukakku.

Pannukakku is a Finnish baked pancake made from a pourable batter of ingredients such as flour, milk and eggs. Instead of cooking individual pancakes in a frying pan, cooks spread the batter in a shallow baking tray or sheet pan and bake it until set, often with browned or slightly crisp edges.

The Finnish word pannukakku literally means “pancake,” but it refers to a preparation distinct from lettu, the thinner pancake cooked on a stovetop. This difference explains why pannukakku is sometimes compared with other oven pancakes, including the American Dutch baby, even though the recipes and traditions are not identical.

Pannukakku is commonly eaten as a dessert with whipped cream, jam, sugar or fruit. It is also familiar in Finnish communities abroad, especially in the United States and Canada, where it may be served at breakfast. Åland pancake is a related regional specialty, usually thicker and flavored with cardamom, but it is not the general Finnish term asked for here.
