Amman, Jordan

AS a young student at the multinational Aramco school in Dhahran, Saudi Arabia, Fadi Jaber, a son of Palestinian refugees, always preferred his American classmates’ cupcakes, brownies and chocolate chip cookies to his mother’s pastries: knafah, qatayef and baklawah.

But when he tasted a vanilla-frosted vanilla cupcake from the Magnolia Bakery in Greenwich Village in 2004, it changed his life. He quit his marketing job at Unilever and used his savings to enroll in a baking and culinary management program at the Institute of Culinary Education in Manhattan.

And after an internship at Billy’s Bakery in Chelsea, he was ready for his next move: In July 2007, in Amman, Jordan, he opened Sugar Daddy’s, the shop that brought the cupcake craze to the Middle East.

Cupcake shops have become as ubiquitous as hot dog stands in some American cities, and have spread to Rome; Istanbul; Berlin; Seoul, South Korea; and Sydney, Australia. Now Mr. Jaber has proved that even the Arab world is not immune to such a Western frivolity.
