I'll be perfectly honest — I'm not much of a baker. The precise measurements, the exact timing of everything, it's not really my game. But, for this cake, I make an exception. For chocolate (especially dark chocolate) you should always make an exception. Rich, dark, fudgy, with a little crunch from the walnuts, let's just say this is not a chocolate cake for the I-just-kind-of-like-chocolate person.
