Knead 300 g flour, 100 g sugar, vanilla sugar, margarine in flakes and 2 tablespoons cold water first with the dough hooks of the mixer, then with your hands briefly to a smooth dough. Shape into a flat brick, wrap in foil, chill for about 1 hour.
Preheat oven (electric cooker: 180 °C/circulating air: 160 °C/gas: see manufacturer). Line two baking trays with baking paper. Roll out the dough on a little flour to a thickness of about 3 mm. Cut out a total of 70-80 moons (à approx. 6 cm), kneading, rolling out and cutting out the dough again and again. Place the biscuits on the trays. Bake them one after the other in a hot oven for about 8 minutes until golden brown. Mix 100 g sugar with cinnamon. Remove cookies from the oven. Immediately sprinkle half of the biscuits generously with cinnamon sugar and let them cool down.
Wash the orange hot, dab dry and finely grate half the peel. Squeeze the orange. Puree 125 ml juice and peel with cashew nuts in the universal chopper to a fine nut puree. Spread each biscuit without cinnamon sugar with cashewmus, place cinnamon sugar biscuits on top and press lightly. Keep cool in tins.
