Grind the candied lemon peel finely in the universal chopper. Chop the chocolate. Melt 100 g chocolate over a warm water bath. Dice marzipan. Put quark, flour, baking powder, cocoa, sugar, vanillin sugar, citronate, salt, cognac, eggs, quark and 125 g butter in flakes into a mixing bowl.
Knead with the dough hook of the hand mixer. Allow melted chocolate to run in and knead. Knead in cherries and 100 g chopped chocolate. Knead again with floured hands on a floured work surface.
Knead the marzipan carefully. Roll out to a rectangle (25 x 20 cm) on a floured work surface. Whip into a stollen. Place on a baking tray lined with baking paper. Bake in a preheated oven (electric range: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 30 minutes.
Then switch the temperature down (electric oven: 175 °C/ circulating air: 150 °C/ gas: stage 2) and bake for a further 25-30 minutes. Melt 125 g butter. Take the stollen out of the oven, immediately brush with 1/3 of the butter and dust with 50 g icing sugar.
