I had seen a friend of mine post pictures of rainbow cupcakes that she had made for St. Patrick's Day and thought that concept would be neat for Josie's cake. I started with a WHITE cake recipe. Only a white cake will do for this because it won't affect the colors of the food coloring used to dye the batter. Each cake pan (I made two Elmo's) used 6 cups of batter. So, I separated each of the 6 cups into separate bowls, dyed them each a different color (red, orange, yellow, green, blue and purple) and poured them into the pan and swirled.
The next step was filling and crumb-coating the cakes.
And then I began to work on the colors. Getting that red took quite a bit of work and entire bottle of food coloring!
It's beginning to look a lot like...
