For the spice cookies, first prepare the spice dough. For this, cream butter with sugar and vanilla sugar, stir in yolks. Mix the fruit and spices with flour and knead together with the Cointreau with the butter decoction.
Shape the dough with the help of baking paper into a *rod* with 2 cm edge length (will be about 40 cm long) and refrigerate overnight.
For the second dough, cream butter with sugar and vanilla sugar, stir in yolks.
Sift cocoa and cinnamon with the flour and knead in. Wrap the dough in plastic wrap and refrigerate overnight as well.
The next day, roll out the dough into a rectangle of about 40 cm, wrap it around the spice dough stick, press it down well and chill again for at least an hour.
Cut into slices about 3 mm thick and bake at 180 °C for about 10 minutes.
