Hazelnuts and peanuts fry on a dry pan, cool and grind with your hands, removing the skin. Nuts grind in a blender. Add ground cookies, sugar, one egg, protein and lemon zest (zest gives the cookies a citrus, if you want a more nutty flavor, the zest is better not to add), Stir until smooth.

Divide the dough into small balls, put on cookie sheet and flatten the tube from the voucher or a glass. Recesses to fill with stuffing. Bake in a preheated 200*C oven for 20-25 minutes.
