Yesterday I decided to try my hand at making the rainbow cake shown here:
http://www.omnomicon.com/rainbowcake I didn't make the weight watchers version, though. I just did a box cake with food coloring. The results came out well enough but I think I'll be making some changes next time I make it.
First mistake I made was forgetting that one box of cake mix makes 2 cakes. I put all the mix into one pan which is why that horrible crack is on top of it.
The next really isn't a mistake but an annoyance. I used gel coloring because it makes the colors more vibrant but I couldn't seem to get the red the right shade. I think next time, if I start with an already pink cake and add coloring it might turn out better.
I kind of have a hard time eating this cake. I keep looking at it and expecting all the colors to taste different. But no, they don't, and it's kinda driving me crazy >.
