Quickly mix the sugar, vanilla sugar, butter in flakes, flour, egg and gingerbread spice with the dough hooks of the hand mixer to a smooth dough. Wrap in foil and chill for about 30 minutes. Roll out the dough on a floured work surface and cut out 12 rocking horses (10 x 11 cm), Christmas trees (9 x 6 cm) and Santa Clauses (10.5 x 7 cm). Place on 3 baking trays lined with baking paper. Bake the trays one after the other in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 12-15 minutes. Remove cookies from the oven and let them cool down on a cake rack.
In the meantime, beat the egg whites, lemon juice and icing sugar until stiff, while pouring in the icing sugar. Spread evenly on 4 bowls. Colour one part each red, orange (red and yellow) and green. Pour the icing into one freezer bag each, cut off a small corner and decorate figures with it. Decorate with colourful sugar beads and let dry
