Searching for kid’s birthday cake designs is so much fun, because every choice is just as good as the next one! Our Barbie confection uses various shades of green fondant to create a Tinker-Bell Barbie wearing a gown that billows from her waist, ending in a hemline of etched green leaves. Vines of flowers decorate this kid’s birthday cake, which is available at your local Las Vegas bakery. Don’t forget to order a couple of dozen kid’s birthday cake cupcakes for this special occasion!
