Grease the troughs of a muffin tray (12 troughs) and dust with flour. Preheat the oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer). Melt 125 g butter and 125 g chocolate coating in a hot water bath, allow to cool slightly.
Separate eggs. Mix egg yolk and sugar until creamy. Stir in the chocolate butter. Mix 100 g flour and baking powder. Stir in briefly. Beat egg whites until stiff and fold in. Spread the dough into the bowls. Bake in a hot oven for 20-25 minutes.
Let it rest for about 15 minutes. Then remove from the troughs, lift out and let it cool down.
Knead marzipan, rum and 60 g icing sugar. Roll out to a little icing sugar about 2 mm thin. Cut out 12 circles (each approx. 5 cm Ø). Knead the rest of the marzipan together again and put aside. Stir jam until smooth.
Cut the muffins in half horizontally. Spread the cut surfaces with jam. Place marzipan circles on the lower muffin halves. Place upper halves on top.
Roll out the rest of the marzipan just as thin. Cut out 12 circles (each approx. 8 cm Ø). Spread the muffin surfaces with Rest Jam. Place the marzipan circles on top and press down gently. Chop 500 g chocolate coating.
Melt with coconut oil in a hot water bath. Cover muffins with it and let them dry.
Dust the muffins with icing sugar figures with stencils as desired.
