I've been dying to bake this cake for some time now, so I spent Sunday night baking, layering and frosting all 11 layers for my boss's birthday. I baked each layer individually - 12 total, but only 11 made it into the cake, one on the floor - in disposable pans so I wouldn't have to wash over and over (thanks for the great tip, Bakerella).
Then stacked them with chocolate ganache
and frosted the sides with a hot fudge butter cream.
I think this cake was gone in record time - less than 45 minutes!
