Rainbow Cupcake Cake

I love how this cupcake rainbow cake turned out. It was so much fun to decorate & the birthday girl and mom were very pleased. I ended up using 40 cupcakes and it was pretty big. I didn't measure it, but the board was around 27" wide and 19" high.

Nadia was turning 5 so I decided to pipe her number with all the colors of the rainbow.
