I modified this recipe to something that I had seen in the past which requires you to use 12oz of sprite zero instead of oil eggs and water. It makes it a diet version I guess. It tastes amazing, though it looks lumpy when you put it in a pan. I also like to use gel neon food coloring for a sweet look. :)

I separated the batter into 5 colors. Red, orange, yellow, green and blue. Which is funny because it ended up being pretty close to one cup of batter per color. Everyone commented on how cool it was. With the bundt pan the dough actually bent to form a rainbow once cut. Awesome! Thanks for making my daughter's birthday a success!
