Bring butter, 100 g sugar, 1 packet vanilla sugar and flaked almonds to the boil, simmer for about 8 minutes. (Almonds should be slightly brown.) Stir in 5 tablespoons of milk, let almond paste cool down. Mix 200 g quark, 8 tablespoons milk, oil, 75 g sugar, salt and 1 packet vanillin sugar with the whisk of the hand mixer. Mix flour and baking powder and stir half of it into the dough by the spoonful. Knead in the remaining flour. Grease a springform pan (26 cm Ø) and dust with flour.
Fill in the dough and press it smooth. Spread almond paste on it. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 30 minutes on the bottom shelf. (After about 20 minutes cover the cake so that the almond paste does not get too dark). Take out the cake and let it cool down on a cake rack. Wash and drain the sultanas. Mix 700 g quark, mascarpone, 175 g sugar and lemon juice with the whisks of the hand mixer until smooth. Stir in the sauce powder well, mix in the sultanas. Cut the cake in half horizontally. Place a cake ring around the bottom cake base. Spread the cheese mixture on top and chill for about 2 hours.
