Finely grate the zucchini, put them into a kitchen towel or paper towel and drain as much fluid as possible
Break the chocolate into pieces and melt them
Pit the cherries and cut them into small pieces
Put flour, sugar, baking powder, cocoa and vanilla into a bowl and mix well
Then add oil, sparkling water and apple cider vinegar and stir into a smooth dough
Mix in the zucchini, chocolate and cherries (you can mix again, so everything will be very fine)
Grease a loaf pan and put dough inside
Bake for 40-50 minutes – check with stick if well done
Melt some chocolate for the glaze and pour over the cooled off cake. Place the cherries on top of the liquid chocolate.
