|batter before the oven|
1 white cake mix
1/3 cup of oil
1 cup water
red, yellow, green, blue, and violet gel food coloring
Mix cake mix, eggs, oil and water together. Separate batter into six different bowls (no Indigo for me, poor lonely Indigo). Using a toothpick, add desired amount of food coloring to batter. If using gel colors, remember that it takes some time for the color to reach full vibrancy. I don't have orange food coloring, not even sure Wilton makes it, so I just mixed red and yellow.
Grease and flour a 9*3 round cake pan. Scoop 1-2 scoops of red batter into the pan. Next scoop 1-2 scoops orange batter and put it directly on top of the red batter. Then scoop 1-2 scoops yellow batter and put it directly on top of the orange batter. Lather, rinse, repeat with the remaining colors. I had to repeat the pattern about 3 times in total. The batter will spread itself out.
Bake at 350 degrees for 45 minutes or until an inserted toothpick comes out clean.
Frost and decorate as desired. I used the American Buttercream that my family is so fond of.
|cake after baking|
1/2 cup butter
1/2 cup shortening
4 cups powdered sugar
1 tsp salt
1 teaspoon vanilla
5-7 tablespoons of water
Beat together the butter and shortening until smooth. Add the vanilla. Slowly add the powdered sugar. If the mixture gets too thick and your mixer is having trouble, add some water or milk a one tablespoon at a time until the desired consistency is reached.
I only frosted the outside of this cake. Double the recipe if filling the cake.
