Finely chop the candied cucumber. Dice marzipan finely. Mix quark, eggs, salt, sugar, vanilla sugar, cinnamon and 100 g butter with the whisk of the hand mixer. Mix flour and baking powder, add and knead with the dough hooks of the hand mixer.
Knead in the candied peel, almonds and raisins. Then carefully knead in the marzipan. Line muffin troughs (12 pieces) with 2 paper sleeves each. Spread the dough evenly into the troughs using a tablespoon.
Bake in the preheated oven (electric: 175 °C/ gas: level 2) for 25-30 minutes. In the meantime, melt remaining butter in a small pot. Take the muffin tray out of the oven and place it on a grid.
Spread the still warm muffins with the melted butter and let them cool down. Lift the muffins out of the troughs and dust with icing sugar.
