Grate the chocolate for the dough. Cream butter, 250 g sugar and 1 pinch of salt with the whisk of the mixer. Stir in the eggs one by one. Mix flour, baking powder, cocoa, cinnamon, cloves and chocolate rasp and stir in briefly. 1⁄8 l Stir in wine briefly.
Put the dough into a greased, flour-sprinkled box form (approx. 2 1⁄2 l capacity) and smooth it down. Bake in the preheated oven (electric oven: 175 °C/circulating air: 150 °C/gas: see manufacturer) for approx. 50 minutes.
For the syrup, bring 150 g sugar and 150 ml wine to the boil in a small pot and simmer for about 5 minutes.
Remove the cake, prick it several times with a wooden skewer and sprinkle it with half of the syrup. Continue baking for about 10 minutes.
Take the cake out again, spread with the remaining syrup and bake for about 5 minutes. Leave to cool for about 1 hour. Then carefully turn out and let it cool down. Dust with icing sugar. Cherry compote tastes good with it.
