Double Rainbow Cake - All the Way

It was my good friend Tony's Birthday, and I decided to make his birthday cake. I had been searching for a idea on Tastespotting.com when a came across the "perfect cake"
For weeks Tony had been driving me nuts with the that bloody "Double Rainbow Song" on You Tube

Unfortunately I had run out of Red colouring, hence why my red part of the rainbow is clearly pink.

Now time to Decorate........

Yes, I did put on those M&M's one at a time.

Happy Birthday Tony. Yes it was "So Bright, So Vivid."
