Mix flour, 75 g icing sugar, vanilla sugar, salt and cinnamon in a bowl. Add egg, egg yolk and butter in pieces. Knead first with the dough hooks of the hand mixer, then briefly with your hands to a smooth dough. Wrap in foil and chill for about 1 hour
For the filling, grind 75 g pistachios finely in the universal chopper. Knead with marzipan and divide into 3 equally heavy pieces. Form a 30 cm long roll from each piece of marzipan
Cut the short pastry into 3 equally heavy pieces. Roll out 1 rectangle (10 x 30 cm) one after the other on a lightly floured work surface. Spread thinly with approx. 1 tbsp. milk. Place a marzipan roll on each and roll it firmly into the dough. Cut off any protruding dough ends. Put the rolls in a cool place for about 30 minutes.
Place the rolls with the seam facing downwards on a baking tray lined with baking paper and bake in a preheated oven (electric range: 175 °C/ convection oven: 150 °C/ gas: level 2) on the 2nd rack from below for approx. 25 minutes. Take out and let cool down
Coarsely chop 25 g pistachios. Mix 50 g icing sugar and 1-2 tbsp. milk to a smooth glaze. Pour in strips over the rolls. Sprinkle the rolls with the remaining pistachios and cut them carefully into slices of about 1 cm thickness
waiting time approx. 1 1/2 hours
