Melt the clarified butter. Add sugar, vanilla sugar and salt and mix with the whisk of the hand mixer. Mix eggs and cream and stir into the butter-sugar mixture. Mix flour and baking powder, sieve onto the fat mass and fold in.
Remove half of the dough. Stir in cocoa. Season other half with gingerbread spice. Cover 3 baking trays with baking paper. Layer 1 teaspoon of each of the light pastry and 1 teaspoon of the dark pastry and alternately press 1 Brazil nut and 1 macadamia nut into the top.
Bake one after the other in a preheated oven (electric oven: 175 °C/ convection oven 150 °C/ gas: stage 2) for about 20 minutes. Approx. 5 minutes before the end of the baking time, spread chocolate rolls on some of the biscuits.
Let the sheets cool down on a grid.
