Cut the butter into pieces. Knead the sugar, butter, flour, gingerbread spice, cocoa and egg first with the dough hooks of the hand mixer, then with your hands to a smooth dough. Wrap the dough in foil and chill for about 30 minutes
Roll out the dough thinly on a work surface dusted with flour and cut out pretzels (approx. 6 x 4 cm). Place the pretzels on 2 baking trays lined with baking paper. Knead the dough again and cut out as well
Bake the trays one after the other in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 8 minutes. Let the biscuits cool down on a cake rack
Roughly chop the chocolate. Melt the chocolate and coconut oil slowly in a bowl over a warm water bath. Chop the pistachios a little smaller. Dip the pretzel with the surface into the chocolate, drain well and place on a cake rack. Sprinkle with pistachios and chill until dry
Waiting time approx. 1 hour
