I recently had an order for 2 large sheet cakes for a surprise 70th birthday party. For most bakers this would be a cake walk, so to speak. For me, however, it involved an all-nighter with several trips to Taco Bell for caffeine reinforcements. I was just a bit nervous about this undertaking. Here is what I came up with. Keep in mind this was my first attempt at a sheet cake (I seem to say that a lot).
