Mix flour, baking powder, sugar, vanilla sugar, gingerbread spice and 1 pinch of salt in a bowl. Add butter in pieces and eggs. Knead first with the dough hooks of the mixer, then with your hands to a smooth dough.
Knead cranberries and pistachios. Cover the dough and chill for about 30 minutes.
Line a baking tray with baking paper. Preheat the oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer). Quarter the dough and form each into a roll (approx. 3 cm Ø). Place on the baking tray with a little space between them.
Bake in a hot oven for about 15 minutes. Let it cool down.
Line two baking trays with baking paper. Cut rolls diagonally into 3-4 mm thin slices. Spread the slices flat on the trays. Bake one after the other at the same temperature for 8-10 minutes until golden brown.
Take out and pull off the sheet together with the paper. Let it cool down.
