Bright and Cheerful Rainbow Cake

Bright and Cheerful Rainbow Cake

Follow Me on Pinterest
I made a little rainbow cake last week. 
It wasn’t for my birthday…or for your birthday…

or for the birthday of any other fine person!

It was a cake made out of desperation, my friends.

I was desperate for a little color and sunshine. And since the sky was gray and brooding and since my boys and I had seen Star Wars for the ump-teenth time in a week (I’m starting to speak Chewbaccan) and since I had attempted several new dinner recipes that tasted disgusting and looked ugly…I was in a desperate state, as you can well imagine! It’s one thing to look like Chewbacca (have I mentioned that I have really unruly hair? It’s true. Don’t hold it against me, okay?) but when a girl starts to speak like him, well then there is nothing to do but throw your hairy hands in the air and bake a cheerful cake. Nothing at all, but that. 

And so my boys and I, we baked this cake. And I thought you  might like to see how to make it all happen.  Just in case you are planning to have a birthday this year. 🙂 And if not, maybe you KNOW someone who will be having a birthday this year. And if that person likes cheerful cakes, well then you will be all set, won’t you. 

Bright and Cheerful Rainbow Cake
Time: 90 minutes
Yield: 12-15 servings
Recipe from Jamie Cooks It Up!
1 white cake mix + listed ingredients needed to bake the cake
Americolor Food Coloring Gel Paste
Wax Paper or Parchment Paper
1 batch Buttercream Frosting (recipe found here)
1 (14 ounce) bag of skittles
1. Mix the cake according to package directions. Pour equal parts of the batter into four bowls. 
 This food coloring gel paste can be found at Hobby Lobby and most craft stores, 
or baking supply stores.
2. Pour a little food coloring into each bowl and stir it in with a spoon. 
3. Lay the bottom of your round cake pan on top of two sheets of wax paper or plastic wrap. Draw a line around the pan with a pencil. Cut two circles out of the wax paper. 
4. Spray each pan with cooking spray (cooking spray with flour works the best). Lay a piece of wax paper into the bottom of each pan and spray it with cooking spray.
5. Take the blue batter and plop three or four dollops into each pan. 
Then repeat with the other colors, making sure to distribute the batter randomly. 
6. Bake the cake at 350 degrees for 25-35 minutes, or until a toothpick inserted into the center comes out clean. 
7. Remove the cakes from the oven and let them rest in the pans for 10 minutes. Take them out of the pans and let them cool completely on a wire rack. 
8. Make yourself some lovely buttercream frosting. Click here for recipe and tutorial
9. When your cakes have cooled spread about 3 tablespoons of frosting into the center of a cake plate or pedestal. 
10. Carefully place one of the cake layers into the center of the plate. Slide a few sheets of wax paper underneath the cake. This is to help keep your cake plate nice and pretty. After you are done frosting the cake you will remove the wax paper and all will be lovely. 
11. Spread some of the frosting over the top of the bottom layer. 
12. Place the second cake layer over the first and frost it lightly all around. Don’t be worried if there are a lot of colorful crumbs. Can you see the colorful crumbs on my cake? There are there trust me. This is called a “crumb layer”.  After you have lightly frosted the cake like this, pop it into the fridge for about 20 minutes. This will cause the crumb layer to harden a bit and make it easier for you to frost the cake with a clean crumb free layer of frosting.
13. Take the cake out of the fridge and frost it so that none of the cake (or its crumbs!) are showing. 
14. Get yourself some skittles
and press them all over the cake. You’ll want to be sure to work quickly. Once the frosting has set up it won’t hold the skittles very well.

    I'm going to have to try this. I was anticipating something alot more difficult with the rainbows of colors and was pleasantly surprised that it was this easy. So far I'm loving the Red Velvet Brownies and Grandma's Choc. Chip Cookies (ranked #1 here).

    Hi! I just found your blog thru another blog yesterday as I was looking for an easy bread to go with spaghetti. I made your easy breadsticks lastnight and they are really easy and delicious, Thanks! Can't wait to try your other recipes…the rainbow cake looks so appealing…will try it maybe one of these days…just a tip I want to share with parchment paper on round pans, instead of drawing a line around the pan with a pencil…Tear off a square of parchment paper big enough to cover your cake pan. Fold in half, then fold in half again. Next, fold the square into a triangle. Hold the triangle to the center at the back of the pan. Mark where the paper meets the pan. Using a pair of scissors, cut the triangle along the marks you made in the previous step. Unfold and place the circle in a greased cake pan.

    I might make this for my younger son's birthday next month. He's having friends over for a day of XBOX and wings (his favorite food!) and this cake would be a mighty fine ending to a great, fun day with friends! We'll use M&Ms to decorate teh top instead of skittles I think but I LOVE this idea! SO EASY!!!

    Could I use a cupcake mix of white cake (instead of a full blown cake) and make just one layer??

      Hi Jenn,
      I'm not familiar with “Cupcake Mix”, but if you follow the instructions on the package and then just add the food coloring I think it would turn out great for you as a one layer cake. Good luck!

    That is really interesting! I am sure my grandsons will love this one and helping to bake it. I love the M and M's on top, and it doesn't use the whole big package, so then I could eat the rest! Talk about getting cheered up….that would do it. Thanks for the recipe. A truly Fun Cake!

    Oh Jamie, Jamie, Jamie, you have such fun and good recipes. I might look at this blog a little too much for the good of my health. Everyone compliments me that I make the best desserts…thanks to you. I love reading your blog and the personal aspect of it. I feel like I have already met you and you are a fun long-time friend. Thanks for letting all of us into your life. You always make me laugh with your posts. Can I tell you a little secret? I now feel like I can't make anything if it isn't from your blog. That is saying something because it used to be if my mom didn't make it then I didn't make it. In the recipe area I now look to your blog more then my mom's recipes or my mom. You are fabulous and have done a fabulous job with this blog and your recipes. I LOVE IT!!! Thank you so much!!

      Yes, using a 9×13 pan would work just as well. Good luck! Hope you love it!

    Thanks for the decorating tips (wax paper on the plate, crumb coating and refrigerating). I might actually have some success at making it look appetizing.

    No WONDER you looked so cheerful when I ran into you today! This is gorgeous… so fun! Even if I didn't indulge, it would cheer me up just basking in all those colors as I made it. Great post!

    This looks soooooooo good! I am definitely going to try this one out! On an unrelated note, I wanted to let you know that your ads recently have made it difficult to read the content of your blog. I understand that you get revenue from these ads and I'm in no way saying you should get rid of them, but when I have to click in two separate areas of an ad to get rid of it in addition to clicking away other ads in order to read your posts, it makes me frustrated. I'm not installing an ad blocker yet because I want to support you, but if the obnoxious ads continue, I will install the ad blocker and your will lose revenue. But, please keep posting your super yummy recipes! Thanks!
