Giada De Laurentiis challenges four baking teams to make a cake decoration that shows the ultimate family celebration. After one team is eliminated, the remaining three teams meet their VIP clients, the Busby family from TLC's OutDaughtered. America's favorite quintuplets need an epic cake with puppies, unicorns and rainbows to serve at their 4th birthday party, but with more than 150 guests coming, the bakers are challenged to make a gigantic cake that pleases every member of the family. One team wins $10,000 and gets their cake served at the celebration.
