Key Ingredients & Substitutions for Zwetschgenkuchen
Italian Plums (Zwetschgen): These small, dark plums are the traditional choice for this cake, offering a tart, juicy flavor. If you can’t find Italian plums, you can use other firm plums, but avoid overly ripe or soft ones.
Yeast Dough: This provides the light, airy base typical of German cakes. You can substitute with a shortcrust pastry for a different texture.
Streusel Topping: Made with butter, sugar, and flour, streusel adds a sweet, crunchy layer. It’s optional but highly recommended.
Butter: Adds richness to both the dough and the streusel topping. Use unsalted for the best flavor.
Sugar: Granulated sugar sweetens the dough and streusel. Adjust to taste depending on the sweetness of your plums.
Equipment You’ll Need
Mixing Bowl: For mixing and proofing the dough.
Baking Sheet (Backblech): Traditional for German sheet cakes, providing an even bake.
Spatula: For spreading the dough and layering the plums.
Knife: For slicing the plums into quarters.
Stand Mixer (Optional): Useful for kneading the dough, though it can also be done by hand.
Step-by-Step Instructions for Perfect Zwetschgenkuchen
Step 1: Prepare the Yeast Dough
- Activate the Yeast: In a small bowl, combine 1 cup (240ml) of warm milk (about 110°F or 45°C) with 2 ¼ tsp active dry yeast and 2 tbsp sugar. Let it sit for 5-10 minutes until frothy.
- Mix Dough Ingredients: In a large mixing bowl, combine 3 ½ cups (420g) of all-purpose flour and ½ tsp salt. Add the yeast mixture, 4 tbsp melted butter, and 1 large egg.
- Knead the Dough: Knead by hand or with a stand mixer until smooth and elastic, about 10 minutes. The dough should be slightly sticky but pull away from the sides of the bowl.
- First Rise: Place the dough in a lightly oiled bowl, cover, and let it rise in a warm place for 1 hour or until doubled in size.
Step 2: Prepare the Plums and Streusel
- Slice the Plums: Wash and pit about 1.5 lbs (700g) of Italian plums, then slice each into quarters.
- Make the Streusel: In a bowl, combine ½ cup (100g) sugar, ½ cup (115g) flour, and 4 tbsp (60g) cold butter. Use your fingers to rub the butter into the flour mixture until it resembles coarse crumbs.

3: Assemble the Cake
- Preheat the Oven: Preheat your oven to 350°F (180°C).
- Spread the Dough: After the first rise, punch down the dough and spread it evenly onto a greased baking sheet.
- Arrange the Plums: Place the plum slices in rows on top of the dough, slightly overlapping them for full coverage.
- Add the Streusel: Sprinkle the prepared streusel evenly over the plums.
Step 4: Bake the Cake
- Bake: Place the cake in the preheated oven and bake for 30-35 minutes until the edges are golden and the streusel is lightly browned.
- Cool and Serve: Allow the cake to cool slightly before slicing. Serve warm or at room temperature, optionally with whipped cream or a dusting of powdered sugar.
