📝 About This Recipe

Unlike its dense American cousin, the traditional German Käsekuchen is prized for its ethereal, cloud-like texture and a signature tang provided by Quark cheese. This recipe features a buttery 'Mürbeteig' shortcrust base that perfectly cradles a lofty, lemon-scented filling. It is a timeless centerpiece of the German 'Kaffee und Kuchen' tradition, offering a sophisticated balance of sweetness and refreshing acidity.

🥗 Ingredients

For the Shortcrust Pastry (Mürbeteig)

  • 250 grams All-purpose flour (sifted)
  • 125 grams Unsalted butter (cold, cubed)
  • 60 grams Granulated sugar
  • 1 large Egg
  • 1 pinch Salt
  • 1 teaspoon Vanilla extract

For the Quark Filling

  • 750 grams Low-fat Quark (drained if very watery; Greek yogurt is a substitute)
  • 4 large Eggs (separated into yolks and whites)
  • 150 grams Granulated sugar
  • 100 grams Unsalted butter (melted and cooled)
  • 1 packet Vanilla pudding powder (approx. 37g, or substitute with cornstarch)
  • 1 tablespoon Lemon juice (freshly squeezed)
  • 1 tablespoon Lemon zest (from one organic lemon)
  • 1/4 teaspoon Salt

👨‍🍳 Instructions

  1. 1

    In a large bowl, combine the flour, sugar, and pinch of salt. Add the cold cubed butter and use your fingertips or a pastry cutter to work it into the flour until it resembles coarse crumbs.

  2. 2

    Add the egg and vanilla extract to the flour mixture. Quickly knead by hand until a smooth dough forms. Do not overwork, or the crust will become tough. Wrap in plastic and refrigerate for 30-60 minutes.

  3. 3

    Preheat your oven to 175°C (350°F). Grease a 26cm (10-inch) springform pan with butter and lightly dust with flour.

  4. 4

    Roll out the chilled dough on a lightly floured surface until it is slightly larger than your pan. Press it into the bottom and about 3-4 cm (1.5 inches) up the sides of the pan.

  5. 5

    Prick the bottom of the dough several times with a fork. Place the pan back in the fridge while you prepare the filling.

  6. 6

    In a large mixing bowl, whisk together the egg yolks and sugar until pale and creamy. Stir in the melted butter, lemon juice, and lemon zest.

  7. 7

    Add the Quark and the vanilla pudding powder (or cornstarch) to the yolk mixture. Whisk until the batter is completely smooth and no lumps remain.

  8. 8

    In a separate clean, dry bowl, beat the egg whites with a pinch of salt until stiff peaks form. They should be glossy and hold their shape when the whisk is lifted.

  9. 9

    Gently fold one-third of the egg whites into the Quark mixture to lighten it. Then, carefully fold in the remaining whites using a spatula, being careful not to deflate the air.

  10. 10

    Pour the filling onto the prepared pastry base and smooth the top with a spatula.

  11. 11

    Bake in the center of the oven for 60-70 minutes. If the top browns too quickly, cover loosely with aluminum foil after 40 minutes.

  12. 12

    Turn off the oven and crack the door open slightly. Let the cheesecake cool inside the oven for 30 minutes; this prevents the center from collapsing too drastically.

  13. 13

    Remove from the oven and let cool completely at room temperature, then refrigerate for at least 4 hours, preferably overnight, before releasing from the springform pan.

💡 Chef's Tips

If you cannot find Quark, strain full-fat Greek yogurt through a cheesecloth for 4 hours to achieve a similar consistency. To avoid cracks, ensure all filling ingredients are at room temperature before mixing. Do not skip the slow cooling process in the oven; the residual heat helps the structure set without a sudden temperature shock. For an extra smooth filling, pass the Quark through a fine-mesh sieve before adding it to the batter. If the dough is too crumbly to roll, add one tablespoon of ice-cold water and knead briefly.

🍽️ Serving Suggestions

Dust the top lightly with powdered sugar just before serving for a classic look. Serve with a dollop of lightly sweetened whipped cream (Schlagsahne). A warm raspberry or sour cherry compote provides a beautiful tart contrast to the creamy filling. Pair with a strong German filter coffee or a cup of Earl Grey tea. During summer, garnish with fresh red currants or sliced strawberries for a vibrant finish.
