Today I am sharing a cake that is guaranteed to brighten your day! Look at all those beautiful RAINBOW colors... This cake combines the awesomeness of tie dye and rainbows... Doesn't it make you smile? I used the cake coloring technique (not the recipe) found at Omnomicon. I wanted the outside of my cake to be as colorful as the inside, so I added my own tie dye design to the top. Start by preparing a white cake mix. Divide it into 6 bowls, and make each bowl a different rainbow color. Line the bottom of two 9 inch cake pans with wax paper, and grease the sides. Layer your cake batter in concentric circles. Use about 3/4 of the bowl for your bottom color, then use a little less of each color as you continue. Layer your second cake pan in the opposite order. Bake your cake as directed on the box.
Let the cake cool, then frost with your favorite white frosting. Next, you need food coloring gel in your 6 rainbow colors. Make concentric circles with the gel on the top of your cake. This is how I did it: Recipes.
