In an event which would have been unthinkable a few decades ago, a local bakery is competing on food television to win $10,000 for its cupcake. Cupcake DownSouth, which has stores in Charleston, Mt. Pleasant and Columbia, will appear on the Oct. 19 episode of Food Network’s Cupcake Wars, an elimination challenge judged by a cupcake mogul and online macaroon company chef. Four bakeries are featured in the showdown, which has previously produced winning entries such as a “Salted Caramel Cupcake with Pecan Coconut Brittle Crumble and Caramel Swiss Buttercream” and a chocolate chip cookie dough cupcake. Charleston’s cupcakery may want to claim its cash prize while it can: the Wall Street Journal in April reported “the icing is coming off America's cupcake craze,” citing the slippage of the Crumb chain’s stock price from $13 a share in mid-2011 to $1.70 earlier this year. The show airs at 8 p.m.
