Wash and drain the raisins. Chop the candied lemon peel roughly. Cut 125 g fat into cubes. Sieve the flour and baking powder onto a work surface and press a depression in the middle. Add eggs, sugar and vanillin sugar to the middle and mix with some flour to a pulp. Add quark, salt, rum and fat cubes to the porridge and knead everything into a smooth dough. Knead in raisins, candied lemon peel and almonds.
Let dough rest for about 40 minutes. Roll out to a rectangle (approx. 32x42 cm) on a floured work surface and form into a stollen. Place the Stollen on a baking tray lined with baking paper and bake in a preheated oven (electric range: 200°C/ gas: level 3) for 60-70 minutes. Melt the rest of the fat, spread 1/4 on the still warm stollen and sieve 1/4 of the icing sugar on top. Repeat the process several times. Results in approx. 25 slices
