A cake recipe for all foodies:
Cream butter, stir in grated powdered sugar, nuts, chocolate until you get a smooth dough. Form small balls from it and put them in the refrigerator for 1/2 hour to chill.
Press the balls lightly – with spacing – onto a baking sheet lined with parchment paper. Bake for 20 minutes at 160 °C. Place on a wire rack to cool.
