Baking Thuringian Quark Streusel Sheet Cake From Scratch
Thuringian Quark Streusel Sheet Cake is a traditional German pastry that combines a crumbly base, a thick layer of creamy quark, and crunchy butter streusel baked on a single pan, as reported by berliner-kurier.de. The baking process yields enough slices for a Sunday coffee table with leftovers to spare. The recipe requires a deep baking sheet measuring about 30 by 40 centimeters equipped with a high edge to prevent the quark filling from spilling over during the 40 to 45 minutes bake time at 180 degrees Celsius.
Essential Ingredients for the Dough and Filling
Preparation begins with assembling the core ingredients for both the pastry base and the crumb topping. According to berliner-kurier.de, the dough utilizes 300 grams of cold butter, 500 grams of wheat flour Type 550, three teaspoons of baking powder, 200 grams of sugar, one egg, and a pinch of salt. Genuss-suche.de notes that bakers can alternatively use wheat flour Type 405 with 150 grams of cold butter, 100 grams of sugar, one egg, one teaspoon of baking powder, one packet of vanilla sugar, and a pinch of salt for the base.
The filling requires one kilogram of quark, 180 grams of sugar, three eggs, and one packet of vanilla pudding powder, alongside 100 grams of melted butter, the finely grated zest of one lemon, and two tablespoons of lemon juice, as outlined by berliner-kurier.de. Genuss-suche.de adds that incorporating 200 grams of schmand into the quark mixture helps maintain a pleasant consistency when utilizing 20 percent fat quark.
Step-by-Step Preparation and Baking Instructions
The baking process starts by cutting the cold butter into small cubes and kneading it together with the flour, baking powder, sugar, egg, and salt until a crumbly texture forms, ensuring the mixture does not become a smooth ball. Two-thirds of this mixture is pressed evenly onto the lined baking sheet to form the base, while the remaining third is reserved in the refrigerator. Deutschekuche.com emphasizes that this method allows home bakers to produce a classic sheet cake using standard pantry staples without advanced culinary skills.
The filling is prepared by whisking the quark with melted butter, pudding powder, sugar, eggs, lemon zest, and lemon juice until smooth, before spreading the mixture evenly over the dough base. The reserved refrigerated dough is then crumbled over the quark layer by hand. After baking until the streusel turns gold-brown, the cake must cool completely on the pan so the quark filling can set and slice cleanly.
