Which German pastry is a rectangular yeast cake topped with plums and streusel?

Zwetschgenkuchen is a German pastry made from yeast dough topped with plums and often streusel.

The name refers to Zwetschgen, a type of European plum, and Kuchen, meaning cake. The fruit is arranged closely over the dough before baking, producing a moist, tart topping. Some versions finish the cake with cinnamon sugar, crumbs, or a layer of streusel.

The pastry is made in many German-speaking regions and has numerous regional names, including Pflaumenkuchen when plums are described more generally. It is commonly baked on a large rectangular tray for slicing and sharing.

It should not be confused with Bienenstich, whose signature topping is caramelized almonds, or with ordinary Streuselkuchen, which may contain no fruit at all. The plums are the defining feature here.
