Pour the cherries into a sieve and drain well. Wash lemon hot, grate dry and grate peel thinly. Use the rest of the lemon for other purposes. Whisk butter, salt, sugar, vanillin sugar and lemon zest with the whisk of the hand mixer until thick and creamy white. Stir in the eggs one after the other. Mix flour and baking powder and stir in alternately with the yoghurt.
Grease the cake pan (approx. 2.5 litres capacity) and sprinkle with flour. Spread the dough alternately with the cherries evenly. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 60 minutes. Take the cake out of the oven, let it rest for about 10 minutes and carefully turn it over onto a grid. Let the cake cool down, dust with icing sugar and cut into slices
