Separate eggs. Beat the egg whites with the whisk of the hand mixer until stiff, adding sugar. Fold in egg yolks. Sift flour and starch and fold into the dough. Line the bottom of a springform pan (26 cm Ø) with baking paper. Fill in sponge mixture and smooth it down.
Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for about 15 minutes. Loosen the cake edge and let it cool down on a grid. Cut the sponge cake horizontally once. Soak gelatine in cold water. Mix quark, yoghurt, lemon juice and icing sugar until smooth. Whip the cream until stiff and allow the vanillin sugar to trickle in. Dissolve the gelatine at low heat. Stir some quark into the gelatine. Add the gelatine to the remaining quark and stir in. As soon as the cream begins to gel, fold in the cream. Place the bottom cake layer on a plate and enclose with a cake ring. Fill in half of the cream and smooth it down.
