To wrap up their long RV vacation, Buddy Valastro and his family travel through Tennessee to take in the beauty of the Great Smoky Mountains and stop by the Dollywood theme park! Then, they enjoy some Southern comfort eats like apple fritters at the Applewood Farmhouse in Sevierville and juicy burgers at Stock and Barrel in Knoxville. For their last stop, they hit Litton's Market for sweet desserts, which inspire Buddy to head back to the kitchen and put his own touch on their popular Tennessee orange cake.
