Description
Käsesahnetorte is a classic German cake made with light sponge layers and a creamy yogurt mousse filling. Chilled until set and finished with powdered sugar, it is airy, refreshing, and elegant.
Ingredients
1 cup all-purpose flour
1/2 cup granulated sugar
3 large eggs
1 tsp vanilla extract
1 1/2 cups Greek yogurt or quark
1/2 cup granulated sugar
1 tbsp lemon juice
1 cup heavy cream
1 tsp agar-agar powder
1/4 cup water
Powdered sugar, for dusting
Instructions
- Preheat the oven to 350°F (175°C) and grease and line an 8- or 9-inch springform pan.
- Beat the eggs with 1/2 cup of granulated sugar until pale and fluffy. Gently fold in the flour and vanilla extract until just combined.
- Pour the batter into the prepared pan and bake for 20–25 minutes, until lightly golden and set. Let the sponge cool completely, then slice it horizontally into two even layers.
- In a small saucepan, combine the agar-agar with 1/4 cup water. Bring to a gentle boil and cook for 1–2 minutes, stirring until fully dissolved.
- In a large bowl, mix the Greek yogurt or quark with the remaining 1/2 cup sugar and the lemon juice until smooth. Stir the warm agar mixture into the yogurt mixture.
- In a separate bowl, whip the heavy cream until soft peaks form. Gently fold the whipped cream into the yogurt mixture to create a light mousse.
- Place one sponge layer back into the springform pan. Spread the yogurt mousse evenly over the sponge, then place the second sponge layer on top.
- Refrigerate the cake for at least 4 hours, or until the mousse is fully set.
- Remove the cake from the pan, dust the top with powdered sugar, slice, and serve chilled.
Notes
Add fresh berries between the sponge and mousse layers for extra flavor and color.
Use quark instead of Greek yogurt for a more traditional German texture.
For a brighter flavor, mix lemon zest into the yogurt filling.
Store covered in the refrigerator for up to 3 days.
This cake is best served cold and does not require reheating.
The cake can be made a day ahead to allow the mousse to set firmly.
