(AP) — This undated photo provided by Justin Clark shows a Mario Brothers-themed square cake Clark made in Dallas.
Clark, an amateur baker, typically uses a layer of fondant to cover a simple round cake, and gets creative from there. Shows like Ace of Cakes, Cake Boss and various spinoffs tempt viewers with stunning visions of creations closer to art than dessert. This is the era of 3-D baking, and the simple, square birthday cake is little more than a remnant of the past. (AP Photo/Justin Clark)
