To follow tradition for a King Cake, hide a plastic baby doll in or under the ring after baking. Make sure to buy a new small plastic baby and large enough for no one to swallow. Additionally, caution everyone to look for the baby before eating. Another option is to hide something edible like a pecan or cherry and decorate with the baby on the outside of the cake. Traditions vary, for some finding the trinket means luck. For others, the winner is named King or Queen for the the festivities or is given special honors such as hosting the next party.
