Zwetschgenkuchen, Pflaumenkuchen (German: [ˈp͡flaʊ̯mənˌkuːxn̩] ⓘ), Zwetschgendatschi (southern Bavaria) or Zwetschgenplootz (Franconia) is a sheet cake made from yeast dough, shortcrust dough, or cake batter that is thinly spread onto a baking sheet and covered with pitted zwetschgen plums (also called Italian plums) before being baked.

[1] It is popular cake for both home bakers and commercial bakeries when plums come into season at the end of the summer.

[3] It is common to bake it with streusel (a crumbly mixture of butter, sugar and flour), although the original recipe serves it plain without any toppings.

[2] In Hessen, Rhineland-Palatinate, Saarland and Moselle it is known as Quetschekuche, in Bavaria, Baden-Württemberg and parts of Austria it is called Zwetschgendatschi and in Rhineland and the Eifel Prummetaat.

[5] American film star Humphrey Bogart ate plum cake while shooting several famous movies.
