Warm up the milk. Melt butter in it. Mix 400 g flour, yeast, sugar and 1 pinch of salt. Add egg and egg yolk. Add warm milk-butter mixture. Knead the dough first with the dough hooks of the mixer, then with your hands for 5-6 minutes to a smooth dough.
Form the dough into a ball and put it back into the bowl. Cover and leave to rise for approx. 1 1⁄2 hours in a warm place. Knead the dough again with your hands. Then let it rest in the fridge for at least 3 hours.
Knead the dough briefly, roll out and cut 28 donut rings (each approx. 6.5 cm Ø; various sizes at e.g. amazon.de from 6 € plus shipping, or e.g. cut out the outer circle with a glass. For the hole in the middle, use the lower edge of a syringe nozzle.
To prevent sticking, dip both briefly in flour and use the bottom edge of a syringe nozzle for the hole in the middle. So that nothing sticks, dip both briefly in flour).
Let the dough rings rise. Fry in portions. Take out with a skimmer and drain on kitchen paper. Let it cool down.
For the filling, let the raspberries thaw. Puree in a tall mixing bowl and pass through a sieve. Stir 250 g cream cheese, 3 tbsp. icing sugar, lemon juice and zest until smooth. Stir raspberry puree into the cream cheese cream.
In a piping bag with a Berliner spout (available in specialist shops; with its narrow piercing tube it is perfect for filling. To do this, prick the pastry at regular intervals and squirt a little cream into each) and fill the donuts with it.
To serve, place 7 donuts in a circle on a cake plate (approx. 26 cm Ø). Spread the rest of the donuts on the underside with approx. 50 g cream cheese and stack them high on the lower circle - this makes a total of 4 layers.
For the Frosting, mix 200 g double cream cheese, 50 g icing sugar and 4-6 tablespoons milk with the whisks of the mixer. Drizzle over the donuts cake. Sprinkle with sugar pearls.
