Carlo's Bakery's now ships its legendary Rainbow Cake nationwide! This cake is made with six layers of rainbow-colored vanilla cake, piled high, filled with sweet vanilla icing, and covered with rainbow sprinkles! Founded by Carlo Guastaffero in Hoboken, New Jersey, in 1910, Carlo's is today renowned as one of America's very best bakeries. Bartolo Valastro Sr. acquired Carlo's in 1963, and his son Buddy took it over at the age of 17. Thanks to the success of the hit TLC show "Cake Boss," Buddy Valastro and his bakery have both rocketed to international superstardom, but at its heart Carlo's remains an old-school, family-run Italian bakery.
