I stopped watching Food Network’s “Ace of Cakes” because owner Duff Goldman and his motley crew had this horrible habit of building their “epic” cakes out of wire, pipes and wood — not exactly edible. I call that cheating. Still, some of their exterior designs end up being quite cool, such as Charm City Cakes’ “Ghostbusters”-themed dessert that features a pair of Busters and the angry Stay Puft Marshmallow Man. Even cooler, and super logical, is that the cake lights up in the dark. I’m assuming the birthday boy or girl was a double bagger? Check out the “sweet” cake inside.
