A chocolate cake has to be the ultimate chocolate lovers delight: delicious, moist, chocolaty, rich and gooey. Layered and decorated with chocolate ganache, it can only be irresistible. When it comes to decorating a chocolate cake I tend to keep it as simple as possible. A good drizzle of chocolate ganache is all I find is required. That's my personal choice, but by all means you can try other decorations.
