Rainbow Cake Recipe
I saw a picture of this cake one time that was layered with lots of different colors. I thought to myself "how cool would it be to make a rainbow cake." It couldn't be that hard right? Well, I learned that it really isn't that hard! The hardest part is mixing the cake batter with the food coloring just right to get the good deep colors. But even that part was FUN!
So the colors of the rainbow are basically Red, Orange, Yellow, Green, Blue and Purple. In that order. I had no idea of what the colors were and learned that there are other colors too but these are the ones I used in my cake. The "main" colors in my opinion. Red at the top of the arch and Purple at the bottom.
Ingredients for the cake
- 1 Box Moist Supreme Cake Mix, Classic White
- 1 1/4 Cup Water
- 1/3 Cup Vegetable Oil
- 4 Egg, Whites Only
- Preheat your oven to 350 degrees
- Blend cake mix, water, oil and eggs in a large bowl until moistened.
- Beat with a mixer on medium speed for 2 minutes until all lumps are gone.
- Separate cake batter into six small bowls.
- Use the colors of the rainbow to color each different bowl with food coloring. Red, Orange, Yellow, Green, Blue and Purple.
- Prepare your pan to keep cake crom sticking by lightly coating the bottom of the pan with shortening and a flour or sugar dusting.
- Starting with the red cake batter color, spread along the bottom of the pan.
- Orange will go next and go right on top of the red. Pour it on evenly and use a spoon or spatula to spread out to the edges of the red. Be careful not to push too deep or you will mix the colors.
- Do the same with the Yellow, Green, Blue and Purple batters ending with purple on the top.
- Place in the oven and bake for 30 minutes. When toothpick inserted in the center comes out clean, your cake is done.
- Cool the cake for 10 - 15 minutes before removing from the pan.
- To remove from the pan, place upside down on a cooling rack and the cake should just fall out.
Things I learned
- When mixing the food coloring with the cake batter you have to use a lot of drops of the red and blue to get the deep colors.
- To get an orange use 17 drops of yellow food coloring and 3 drops of red. It turned into the perfect orange for my rainbow cake.
- I actually bought the NEON food coloring pack that came with a purple so I didn't have to make purple. This was a lot easier!
- I used more cake batter for the red (bottom layer) of the cake because I wanted it to reach to all corners. If the other colors didn't reach the corners it was ok because the red would be there.
- When spreading the layers, don't press too hard and don't panic if the colors don't go all the way to the edges. It doesn't have to be perfect and when it cooks it will flatten out a bit.
- Make sure you cool the cake before you try to get it out of the pan. Because of how the cake cooks it will not be flat on the top so if you take the cake out of the pan before it is cooled it will crack down the center of the cake.

Because I forgot to buy frosting at the store (opps) we made our own homemade frosting. We did a cream cheese frosting that turned out quite nicely for this cake. Here's the ingredients and how we did the frosting.
Ingredients for the frosting
- 1 Stick of Butter, softened
- 1 package of Cream Cheese
- 2 1/2 cups Powdered Sugar
- 1 Tablespoon Vanilla
- Soften the butter in the microwave (if it's not already soft).
- Mix together the butter and cream cheese in a deep mixing bowl.
- Add the vanilla.
- Add powdered sugar a little cup at a time.
- Mix until creamy.
- Spread on the top and sides of the cake.
Things I learned
- Use a deep bowl when mixing or the powdered sugar will get everywhere (opps)
- It might be easier to start with the cream cheese at room temperture so it mixes better with the butter to start.
- When spreading the frosting on the cake, use big "globs" and it is easier to spread. Also helps so the cake doesn't show through the frosting.
Decorating the cake
For the decoration on our Rainbow Cake we used Gel Frosting. We didn't have every color of the rainbow but we used what we had and I love how it turned out. All you do is make circles on the cake with the gel. Use all colors to start. Make sure the circles are thick in color or you do two or three circles of each color. Then using a knife or small spatula you start in the middle of the cake and drag slowly and softly to the edge of your cake. You have to clean off your knife every time so you don't mix the colors. Do this all the way around the cake.
This Rainbow Cake was quite easy to make. I always figured the colors would mix or they wouldn't bake like they were supposed to. I didn't think the frosting was going to turn out right and decorating would make it look horrible but it turned out AWESOME! See for yourself. . . . . .
