Duff has been cooking since the age of 4, when his mom caught him in the kitchen swinging a meat cleaver while watching Chef Tell on TV. Duff started working professionally when he was 14 at a bagel shop, where he was almost fired for making the sandwiches too big. Ever since then, he’s been putting his own crazy spin on food.
After graduating from the University of Maryland, Baltimore County, with degrees in history and philosophy, Duff went on to study at the Culinary Institute of America at Greystone in St. Helena, Calif. He worked at several acclaimed culinary destinations, including the French Laundry, the Vail Cascade Hotel and Todd English's Olives before returning to Baltimore in 2000 to become a personal chef.
In March 2002, Duff quit his day job and opened Charm City Cakes. There, he was able to show off his creativity, which comes from a long line of artistic genes. The bakery became a household name on the hit Food Network show Ace of Cakes, which aired for 10 seasons.
Duff serves as a judge on Food Network's Holiday Baking Championship and Spring Baking Championship. And with Valerie Bertinelli, he hosts and judges Kids Baking Championship.
