Finely dice dates and figs. Chop the pistachios. Mix spices, flour and baking powder in a mixing bowl. Add eggs, sugar, 150 g fat in pieces, quark, dried fruit and pistachios and knead to a dough with the dough hooks of the hand mixer.
Roll out the dough on a floured work surface in a rectangular shape (approx. 26 x 28 cm; approx. 1.5 cm thick), form into a stollen and place on a baking tray lined with baking paper. In a preheated oven (electric cooker: 175 °C/ circulating air: 150 °C/ gas: see
