Lightly whip the eggs and powdered sugar in the food processor, add the hazelnuts and chocolate sprinkles, mix everything well and spread on baking sheets lined with baking paper with the help of two spoons (or, if you like to mash, with your fingers).
Bake in the electric oven at 180 ° C for about 20 minutes.
The amount is enough for 2-4 baking trays, depending on the size of the biscuits.
