Rainbow Cake

I made a cake for a family party and I didn't really want to go all out, but I decided I wanted to try this new technique that I had seen online somewhere. You split your cake batter into a few bowls and dye it different colors. Then you spoon the batter into your cake pan stacking each color on top of the previous one, creating this rainbow effect that I really love! I had done this once before with my easter cake, but I didn't stack the colors, I just dropped them in by the spoonful randomly and I liked that look as well. I iced the outside just very simply. I had a bunch of leftover colors, so I did my favorite dots.
