The Challenge is part of Food Networks' Throwdown With Bobby Flay, where, as the network puts it:
Chef Bobby Flay is on a secret mission to challenge the absolute masters in one kind of cooking — award winning BBQers, bakers, pizza makers and more — some with a roomful of trophies to prove it. In each episode, one of these cooks thinks Food Network is shooting their profile for a show. What they don't know is that Bobby is going to drop in for a surprise visit and challenge them to an unexpected cook-off. Since they're in their element and Bobby's out of his, prepare for an exciting, tension-filled competition.
Robert Carter's coconut cake is a bit of a legend, receiving praise from Bon Appetit and The New York Times.
