For the dough, place all the ingredients into a bowl and knead it until smooth using the kneading hook on the hand mixer. Wrap in cling film and chill for at least 40 minutes. 

Preheat oven to 175°C (top/bottom heat). Roll out the dough on a lightly floured surface to approx. 0.3 cm thick and cut out desired cookie shapes. Place on two baking trays lined with greaseproof paper and make a hole in each of the cookies using a skewer. Bake on the middle shelf of the oven, one after the other, for approx. 15 minutes. Then leave to cool. 

For the decoration, melt cooking chocolate and white cooking chocolate with microwave oven or “double-boil”.  Place the melted cooking chocolate in a piping bag and cut a small hole to decorate the cookies. Then, finely chop the nuts and dried fruit. Decorate the cookies as desired with sprinkles, nuts and dried fruit.
