I little while ago I came across this, by Meredith at Count it all Joy:
It looks so fun and yummy! I feel this need to make it, but am strapped to find the right occasion. I don’t have kids… my niece and nephew are miles away… and the friend who I know would love it doesn’t have her birthday until October! Hrmph. I am not going to eat an entire rainbow cake by myself. I guess it will have to wait.
You should make it instead. Let me know how it goes.
For now, I will seriously yearn for the rainbow cake goodness.
