Challenge: Incredible Edible Mansions

Five of the country's top pastry chefs take on the world of architecture. Their goal? To recreate some of America's most amazing mansions. The twist? These mansions must be made out of gingerbread. You'll see Victorians, a Frank Lloyd Wright, a Vanderbilt mansion and a huge estate built by John Ringling, complete with a merry-go-round. At the end of the day, one of our gingerbread architects will walk away with $10,000.
