Mix cocoa powder, flour, baking powder and cinnamon and pass through a sieve. Cream soft fat. Stir in the egg first, then the icing sugar and vanillin sugar. Add the flour mixture and knead into the fat mixture with the dough hooks of the hand mixer. Press the dough flat, wrap in cling film and refrigerate for about 1 hour. In the meantime, briefly boil the almonds in a little water, rinse with cold water and remove the skin from the seeds. Halve the almond kernels.
Roll out the dough thinly on a floured work surface and cut out stars of different sizes (from 5-8 cm Ø). Spread on 2-3 baking trays lined with baking paper. Bake one after the other in a preheated oven (electric: 175 °C/ gas: level 2) for 8-10 minutes. Let them cool down. In the meantime, chop the chocolate coating and melt it on a hot water bath, then let it cool down again and put on a little. Then decorate each star with a brush stroke of couverture. Put half an almond on top
