Streuselkuchen
Streuselkuchen, also known in English-speaking countries as crumb cake, is a German specialty. Traditionally, it is made of a yeast dough covered with a sweet crumb topping referred to as streusel. The main ingredients for the crumbs are sugar, butter, and flour, which are mixed at a 1:1:2 ratio.
German Streuselkuchen is usually a flat cake made on a baking tray and cut into oblong pieces. It should be very flat - about one inch - so crumbs make about 50% of its height. Yeast dough is the original; a short crust is possible, too, and a puff pastry at the bottom turns it into a Prasselkuchen.
The recipe allegedly originated from Silesia. Many variants are prepared with fillings such as fruit, poppy seeds or creme or using a shortening-based dough.
