Beat the yolks with the sugar until white and fluffy. Stir in chocolate.
Add the flour (previously sieved(, the chocolate powder and the baking powder.
Beat the egg whites until hard peaks and add carefully with circular movements.
Bake for 35-30min and let it cool down.
Syrup: put the water and the sugar to boil. Once boiling add the brandy and let it boil for 4 minutes.
Once the cake is cold, slice it and with a brush paint the insides with the brandy-syrup until both are soaked in it.
Put the mermelade in the bottom slice and softly put the other one on top.
Chocolate icing. Melt the 20 grams if butter and add the chocolate. Stir untill it melts. Then quickly take off the stove and mix in the cream and the butter until there are no lumos nor white.
Cover cake with the icing and decorate as wanted (strawberries, white chocolate...)
It doesn't have to raise much, just a bit, as seen on the picture below.
