Put the baking mix, soft fat, eggs and 1/4 litre water into a mixing bowl. Mix to a smooth dough with the whisk of the hand mixer. Grease the fat pan of the oven and sprinkle with breadcrumbs.
Add the dough and smooth it down. Bake in the preheated oven (electric oven: 200 °C/ gas: level 3) for 15-20 minutes. Let the gingerbread cool down on the baking tray. In the meantime make a 30-32 cm stencil for the fir tree.
Place on the cooled cake, cut out and lift from the tray. Cut small parcels from the sections. For the icing, beat the egg white and 1 tablespoon of water until stiff. Stir in icing sugar and paint the icing as contours and snowy branches on the fir tree.
Divide the rest of the casting into 4 parts and colour with food colouring red, yellow, green and blue. Fill into breakfast bags and cut off a small corner each. Sprinkle packets with colourful ribbons and decorate with sugar pearls.
