Original German Crumb Cake
Original German Crumb Cake is called Deutscher Streuselkuchen in Germany.
Ingredients for Original German Crumb Cake:
- 500 g (17.6 oz) all-purpose flour
- 1 package of dry rapid-rise yeast
- 3 tablespoons of sugar
- 1 leveled teaspoon of salt
- 1 whole egg XL
- 2 egg yolks XL
- 1 cup of milk
- 250 g (8.8 oz) of butter
- 1 additional egg yolk for brushing the dough
Ingredients for crumble:
- 300 g (10.6 oz) of all-purpose flour
- 150 g (5.3 oz) of sugar
- 1 Dr. Oetker Vanilla Sugar OR 1 teaspoon of vanilla extract
- 180 g–200 g (6.3 oz–7 oz) of butter
Preparation of dough for Original German Crumb Cake:
Mix flour, sugar, yeast, and salt in a bowl. Make a hole in the center and add the egg and two egg yolks. Cover with flour mixture. Warm up the milk (lukewarm) and pour it over the flour mixture. Melt the butter in the microwave and add it to the bowl. Use your handheld mixer with the kneading hooks and mix it all together until the dough is no longer sticking to the sides of the bowl and the dough is starting to bubble. Cover the bowl with a kitchen towel and let the dough rise for about an hour.
In the meantime, prepare the crumbs for your cake. Start by mixing the flour, sugar, and vanilla sugar or vanilla extract. Add in slices of the cold (but soft) butter. Using your hands, work the ingredients between your fingers. Make sure that all the butter is worked into the crumbs. Be careful not to knead too much or you will create a dough, rather than crumbles. The crumbs are done when they fall back in the bowl when you rub them between your hands.
Finishing German Crumb Cake:
Cover a baking sheet (I used size 11″ x 17″) with baking paper. Roll the dough out on the baking sheet or use your hands, covered in flour to press the dough flat onto the baking sheet. Cover the dough towel and let it rise for about half an hour. Once the dough has risen, mix an egg yolk with two tablespoons of milk and brush it onto the dough. Spread the crumbs over the brushed cake.
Preheat your oven to 220°C (425°F). Place the baking sheet with the cake in the oven just above the middle rack and bake for about 15-17 minutes. When done, remove the cake from oven and sift some powdered sugar on top.
This is a very light crumb cake and it is not too dry. It is similar to a coffee cake. I would not recommend adding any fruit on top. For a sheet (yeast) cake with fruit toppings, try my Apple Streusel Cake recipe which is dry enough to absorb any fruit juice. Enjoy!
