Soak currants in rum for an hour. Chop Toblerone. Melt the fat, melt the chocolate in it while stirring, allow to cool a little.
Beat eggs, sugar, salt and cinnamon until frothy until you have a light, creamy mixture. Fold in the chocolate mass. Preheat the oven to 180 ° (electric stove).
Roughly chop walnuts and then add. Stir in the soaked currants and flour. Pour the dough into a mold (20 x 20 cm) lined with baking paper and smooth it out.
Bake at 180 ° for 20-25 minutes. Take out and let cool down a bit. Cut into approx. 25 pieces while still warm. Let cool down.
Melt the cake icing in a water bath. Lift the brownies out of the pan and cover with them. Decorate with chocolate shavings and possibly silver pearls. Let the glaze set.
