Who doesn’t love Elmo? Our My Happy Birthday kid’s birthday cake features Elmo’s smiling face on the side of the bottom tier of this Las Vegas bakery creation. The top layer, which is slightly smaller than the lower one, features your child’s name and age. Both tiers are covered with a medley of fondant polka dots in bold colors and edged around their borders with tiny round candies. You can select a single kid’s birthday cake recipe or one for each of the tiers. It’s one of the best kid’s birthday cake ideas!
