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 dough briefly, roll out and 13-15 donut rings (à approx. 8 cm Ø; various sizes at e.g. amazon.de from 6 € plus shipping, alternatively cut out the outer circle e.g. with a glass. For the hole in the middle, use the lower edge of a syringe nozzle.
So that nothing sticks, dip both briefly in flour). Cover the dough rings and let them rise. Fry in portions. Lift them out and let them drip off on kitchen paper. Let it cool down.
Chop both couvertures separately. Melt each with 5 g coconut oil in a hot water bath. For cat ears, make 2 slits in the donuts. Stick in the almonds. Dip the donuts with the ears in front half each into a chocolate coating.
Drain and allow to dry.
For the decoration, melt the remaining couverture in the bowls again. Pour into small freezer bags. Cut off a small corner each and spray cheeky cat faces on the donuts. Leave to dry.
