Here is where things got tricky (and I got tired). I used 9 cups of powdered sugar for the frosting, and still ran out. I used too much between the layers and things started to lean. Chad shored things up with these skewers and we let it sit overnight.

The next morning (hours before the party) I remembered I had some heavy whipping cream in the fridge. I whipped it up and covered the cake again with more frosting goodness.

The outcome was pretty!

And this face made it all worth it. She was pretty excited for me to cut into the rainbow surprise. It was the sweetest cake I've ever tasted, with all the frosting, but I didn't make this cake for taste... it was for looks.

Here are two more fun cake ideas. I might use this one next. It looks easier. And this one could be fun for Valentines Day. While we are on the subject of edible rainbows, check out these pancakes.
