Crush the chocolate (the amount of milk and dark chocolate can vary according to taste, you can also use air chocolate). Then put all the ingredients - except for the egg - in a bowl and knead. Shape the dough into rolls and place them on a baking tray lined with baking paper.
Bake in the preheated oven at 175 ° C - 200 ° C on the middle rack for approx. 15-20 minutes (with the specified amount, possibly in 2 runs).
Brush the rolls with the beaten egg before and after baking (you can leave it out, it just looks nicer).
This amount makes about 24 relatively small rolls.
