Warm the milk lukewarm. Put the flour in a bowl, make a depression in the middle and crumble the yeast into it. Add 2 tablespoons of sugar and milk and mix with some flour. Cover the pre-dough and let it rise in a warm place for about 20 minutes. Add 70 g sugar, salt, eggs and fat.
Knead with the dough hooks of the hand mixer to a smooth yeast dough and let it rise again for about 30 minutes. Knead the dough once more and divide it into approx. 20 pieces (approx. 50 g each) and form balls. Place on a baking tray lined with baking paper and cover with a tea towel. Heat the oil in a tall pot. Put doughnuts in portions (approx. 3 pieces each) in the hot oil and deep-fry on both sides until golden brown. Use a skimmer to lift them out and let them drip off on kitchen paper. Pour the jam and plum jam into two piping bags with punched holes. Fill the doughnuts with it. Colour the marzipan with food colouring, roll it out and cut out motifs. Mix 100 g icing sugar and juice (colour if necessary).

Use a stencil to dust some of the Berlin motifs from the remaining icing sugar
