Dissolve the cappuccino powder in 50 ml of hot water. Let cool down.
Put the flour, almonds, hazelnuts, sugar and salt in a bowl, distribute the butter in flakes over it, add the cappuccino and stir everything with the dough hook of the hand mixer.
You can either cool the dough a bit or process it immediately.
To do this, shape the dough into several 2 cm thick rolls. Pieces of 1.5 cm are then cut off and rolled into smooth balls. These balls are placed on baking paper and baked at 160 ° C hot air for about 10-15 minutes.
Let cool down and coat with the dissolved hazelnut glaze.
Place the cookies tightly together, then use a cut open parchment bag and the dissolved chocolate icing to draw thin strips over the cookies.
