German Käsekuchen with a light quark filling in a crisp shortcrust base with a tall edge all the way round. The quark makes the cake lighter and taller than an American cheesecake, and the air fryer bakes it gently so the surface turns golden without cracking.

Equipment
1 Air fryer
1 Springform 18 cm Must be able to stand freely in the basket
Mix 175 g wheat flour, 60 g sugar, 1 tsp baking powder and 1 pinch salt in a mixing bowl.
Rub 100 g cold butter into the flour mixture with your fingertips until it resembles coarse breadcrumbs. Add 1 pcs egg and quickly bring the dough together into a ball without kneading it.
Cover the dough with cling film and put it in the fridge for 30 minutes, so the butter turns completely cold again.
Line the bottom of an 18 cm springform tin with baking paper. Press the dough into the bottom and up the side, so you get a tall, even edge all the way round. Prick the bottom with a fork and place the tin in the fridge while you make the filling.
Quark filling
Stir 500 g quark together with 110 g sugar and 2 tsp vanilla sugar until completely smooth.
Add 2 pcs egg one at a time, then stir in 30 g cornflour, 100 ml whipping cream and the finely grated zest and juice from 1 pcs lemon. Stir only until the mixture comes together, as too much air causes cracks.
Pour the quark mixture into the cold shortcrust base and smooth the surface with a dough scraper.
Baking in the Air Fryer
Preheat the air fryer to 150 °C fan.
Place the tin in the middle of the basket and bake the cake at 150 °C for 45 minutes. Loosely lay a piece of baking paper over the top after 30 minutes if the surface gets too dark. The cake is done when the edge is set and the centre still has a slight wobble.
Turn off the air fryer and let the cake sit for 10 minutes in the closed basket before taking it out. Then let it cool completely in the tin and chill it for at least 2 hours, so the filling sets.
Serving
Loosen the edge with a thin knife, remove the springform ring and cut the cake into slices. Serve with 100 ml caramel sauce or fresh berries.
Notes
Tips for the perfect result:
Let the quark drain in a sieve for 15 minutes if it seems wet. A firmer filling rises more evenly and cracks less. Don't open the air fryer for the first 30 minutes, as big temperature swings will make the cake sink in the middle.Variation:
Swap the caramel sauce for fresh berries, a thin layer of jam, or crème fraîche stirred with a little icing sugar. A couple of tablespoons of raisins folded into the quark mixture give a more classic German version.Serving:
Serve the cake cold or at room temperature with caramel sauce or fresh berries, and a dollop of whipped cream if you like.Serving size:
This recipe is designed for an 18 cm springform tin that fits in most air fryer baskets. Measure your basket first, so there's room for air circulation all the way around the tin.
