A few weeks ago was my nephew's first birthday and my sister and I thought it would be fun to make a rainbow cake. It started out in our minds pretty simple of just separating the batter into different pans and putting food coloring in each one. I have to say it did not turn out that easy, but still totally worth it. We basically had a full ROYGBIV cake (minus the indigo). And it looked completely awesome when we cut into it. I was slightly creeped out by consuming all that food coloring and eating unnaturally bright food, but a few weeks later I still seem to be fine.
We used a basic yellow cake recipe and tripled it for all the layers. Then had to bake 2 layers per shift because that was all we could fit. My sister made a basic buttercream frosting and did all the layering with frosting separating each color. Now if only my nephew were old enough to appreciate all the work!

He may not appreciate the work that went into the cake, but I do think he enjoyed eating it. Even if half of it ended up on him.
