Ingredients
- 250 g soft butter
- 200 g sugar
- 1 Päckchen vanilla sugar
- 4 eggs (medium)
- 300 g all-purpose flour
- 1 Päckchen baking powder
- 2 EL unsweetened cocoa powder
- 1 Glas (ca. 350g Abtropfgewicht) sour cherries (drained weight approx. 350g)
- 400 ml milk
- 1 Päckchen vanilla pudding powder
- 200 g soft butter
- 100 g powdered sugar
- 200 g dark chocolate
- 50 g coconut fat (e.g., Palmin)
Instructions
- Preheat the oven to 175°C (350°F) top/bottom heat. Grease a baking sheet (approx. 30x40 cm / 12x16 inches) thoroughly and lightly dust it with flour to prevent sticking.
- In a large bowl, cream together 250g soft butter, 200g sugar, and vanilla sugar until fluffy. Beat in the eggs one at a time until a creamy mixture forms. Mix the flour and baking powder and carefully fold it spoonful by spoonful into the batter.
- Divide the batter in half. Spread one half evenly onto the prepared baking sheet. Stir 2 tablespoons of cocoa powder into the other half and carefully spread it over the light batter. Distribute the drained sour cherries evenly on top of the dark batter and lightly press them in. Bake the cake for 25-30 minutes.
- For the buttercream, cook a thick pudding with 400ml milk and vanilla pudding powder. Let the pudding cool completely, stirring occasionally to prevent skin from forming. It is crucial that the pudding and butter are at the same temperature.
- Beat 200g soft butter with 100g powdered sugar until fluffy. Then gradually beat in the cold pudding spoonful by spoonful until a smooth cream forms. Spread the buttercream evenly over the completely cooled cake. Chill the cake in the refrigerator for at least 30 minutes to allow the buttercream to set.
- For the glaze, slowly melt the dark chocolate and coconut fat over a water bath. Stir until a smooth, glossy glaze is formed.
- Spread the liquid chocolate glaze evenly over the firm buttercream. Immediately draw wave-like patterns into the still-soft glaze with a fork to create the characteristic Danube Wave effect. Let the glaze set completely before serving.
