How fun is this!!! Call me an aesthetic junkie, but I could not resist the urge to jazz up a classic white cake mix.
Start by preparing your cake mix according to the instructions on the box. Then, divide the batter into 6 bowls. (I know there are really 7 colors in the rainbow... but what is indigo, really?) The food coloring box didn't mention how to make this color and I only had so many clean cereal bowls to work with. Humph! Divide the cake mix evenly into separate bowls. Add about 15 drops of food coloring in each cereal bowl.
Then mix it up and spoon into a cake pan. Be careful not to mix the colors together- you are plopping/glopping, not spreading!
Joe and I both had a piece of this tasty treat this afternoon. My RA staff polished off the rest at our staff meeting. I can't wait to try this again with two round cake pans.
