I added chocolate chips to the chocolate part, and this cake turned out quite well. Not as good as mud cake, or banana cake, or carrot cake... but I liked it :) I liked it best when it was warm, but it curbed the chocolate cravings that I've been having since I gave up eating chocolate (bars) a week ago. Success!
