Hot Fudge Pudding Cake

The stated goal for this recipe is a no-fuss chocolate pudding cake, however not only did the recipe fail for us, preparation is decidedly fussy! My 16-yr old son put this together, and it turned out a mess. Not only did it require five bowls to prepare (plus melting chocolate), but upon baking (and yes, he did use the correct pan size) it bubbled up over the pan's edges, spilling all over the floor of our oven.

Some of the problem might be that there were no altitude adjustments; we should have compensated, and its possible we made a mistake. I'd had high hopes for this recipe - coffee is used as the liquid and it should be a luscious mocha flavor. The crunchy baked drips that we pried off the outside of the pan, though, were very tasty - mocha crunch.
