Datschi is a type of sheet cake that is widely popular in Southern Germany. The topping alternatives for a Datschi are endless. The most known version is made with Italian Prune Plums, called Zwetschgen, although an apricot version won my heart last summer. In honor of spring I decided to make a Datschi topped with spring ambassadors: tart rhubarb and juicy, sweet strawberries.
The rhubarb and strawberries as well as the thin crust make this Datschi the more sophisticated, elegant sister of the traditional plum topped "Zwetschgendatschi". I made two slightly different versions: with and without cinnamon. It was, however, impossible to decide which one was more delicious, so I will leave it up to you. I strongly encourage you to serve it with whipped cream, although I'm sure coconut whipped cream or vanilla ice cream would be wonderful as well. On a different note, I like to make this dough by hand, but you can definitely make it in your stand mixer as well.
The dough is adapted from Nicole Stich of delicious:days (for the recipe: http://www.deliciousdays.com/archives/2009/09/03/zwetschgendatschi-wherever-you-go/). —Sini | My Blue&White Kitchen
1 sheet cake
1 ½ tbsp (1 dl) lukewarm milk
fresh yeast [OR 4,5 g / 1 ½ tsp (intant) active dry yeast, used according to packet instructions]
To make the dough:
In a medium-sized bowl, combine milk and crumbled yeast. [If using instant active dry yeast, skip this step. Combine yeast with some flour and add to warm, about 108°F / 42°C, milk mixture just before adding the rest of the flour.] Stir until yeast is completely dissolved. Add sugar, salt, and egg. Whisk until combined. Gradually add most of the flour and knead. Add butter and knead until well combined. Continue to knead and add flour until the dough comes clean off the sides of the bowl and doesn't stick to your hand.
Shape into a ball and cover with a kitchen towel. Let the dough rise in a warm place for about 1 hour, or until it's almost double in size.
Meanwhile, preheat the oven to 355°F (180°C). Line a baking tray with parchment paper.
To make the streusel:
In a small bowl, combine flour, sugar, salt, and butter until you have a crumbly mixture. If not using immediately, put the bowl into the fridge.
Arranging the Datschi:
With a rolling pin, roll out the dough until roughly the size of the baking tray. Spread out on the baking tray and pull into shape. Spread the rhubarb and strawberries in an even layer over the dough. Sprinkle with sugar and, optionally, with some cinnamon. Sprinkle the streusel over the fruit.
Bake for 25–30 minutes, or until the edges are dark brown. Let cool and cut into squares and serve with a generous dollop of whipped cream.
