Yes, the yellow frosting really was THAT bright, haha. This SunshineVanilla cupcake from Georgetown Cupcake is technically on the regular menu, but as a special order item. It consists of "sunshine vanilla frosting on a classic Madagascar bourbon vanilla cupcake".
So, basically the same as the Vanilla Squared cupcake, with a much brighter shade of frosting. These would be cute to order for any sort of kids' party or an occasion where bright and fun colors are being used. It may even glow in the dark, from the looks of it, haha!
