Cut candies into small cubes, chop pecans. Cream butter, sugar and vanilla sugar with the whisk of the hand mixer. Stir in eggs one after the other. Mix flour and baking powder, add to the fat-egg mixture and stir evenly.
Fold in diced candy and nuts. Place the dough by the teaspoon on 3 baking trays lined with baking paper with a large gap between them. Bake the trays one after the other in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 12-15 minutes.
Allow to cool on cake racks.
