TO GO WITH AFP STORY BY VERONIQUE DUPONT A cupcake on display at the Magnolia Bakery February 19, 2010 at Rockefeller Center in New York.  The cupcake, a small, round cake that fits in the cup of a hand, has replaced bed-and-breakfasts and restaurants as the eldorado for entrepreneurs, with some of the boldest eyeing conquests abroad.  A traditional dessert in America, the cupcake is nothing new, but in recent years it has morphed into a must-have gourmet treat, popularized in part when a heroine on the trend-setting television series "Sex and the City" ate one in a 2000 episode.
