At first glance, this recipe seemed difficult because there are so many various steps. But it really was quite easy and worth the effort, because this is a rich, decadent, very-chocolatey cake. The directions only give the baking time for a frozen cake, but I wanted to bake two of them immediately. So I cut the baking time down to 15 minutes, and they were a little overdone. Perhaps 13 minutes would have made the "lava" flow more easily.
