Line two baking trays with baking paper. Cream butter, sugar, 1 pinch of salt and vanilla sugar with the whisks of the mixer. Stir in the egg. Mix flour and baking powder and stir in briefly.
Fold the cranberries into the dough.
Using a tablespoon, place about 10 heaps of dough on each tray with a little space between them and press them slightly flat. Bake the cookies one after the other in the preheated oven (electric oven: 175 °C/circulating air: 150 °C/gas: see manufacturer) for approx. 10 minutes.
Let it cool down.
