Thanks for all the birthday wishes! This fab cake was so fun to make with neon food coloring! The kids love using cake beaters, squirting food coloring and watching the colors come to life when you mix it into the white frosting. The best part is cutting the first slice to reveal how good of a job you really did layering the colored batter. I saw this in Family Fun magazine, they always have such awesome ideas. To top it off we searched the bulk section and finally found gold coins. What's a rainbow without a pot of gold? So while I am at it, Happy St. Patty's day too.
