Throw out all your other chocolate cake recipes. This is the only one you need.
I made this cake (sans raspberries--I don't care for fruit with chocolate). It was so easy (a piece of cake) to make, and so delicious. The icing is almost superfluous, because the cake is moist and rich enough to be eaten alone. But, the light combo of whipped creme and chocolate dripped on it is--well, the icing on the cake.
I didn't have a bunt or fluted pan, so before I made this I went to a cheap retail store and bought one of those new rubbery pans. I bought a fluted tube, but they're available in everything from muffin to spring form. I strongly suggest doing this. I think I paid about 12 bucks for it. I was able to simply peel the pan away from the cake, and present the end product beautifully. It looked like the picture Kraft provided (without the raspberries).
