Pour the baking mixture into a mixing bowl. Add fat, egg and 1/8 litre water and work into a smooth dough with the whisk of the hand mixer. Fill the dough into the cake tins and place on a baking tray.
Bake in the preheated oven (electric oven: 200 °C/ gas: level 3) for about 20 minutes. Place the gingerbread tartlets on a cake rack and let them cool down. Knead marzipan and icing sugar until smooth.
Roll out marzipan thinly between two layers of cling film and cut out 10 figures with a cookie cutter (e.g. star). Decorate the tartlets with marzipan figures, silver balls and silver sugar.
