Layered Rainbow Birthday Cake


Our kids will probably never know what it’s like to have a fancy store bought cake.  I just can’t bring myself to dish out the money to buy one, especially since I stay at home and have the time to make one.  It would most likely be a different story if I was working, because then it probably wouldn’t be worth my time.  Plus, my husband has a fond memory of his mom making all his cakes and so, thus far, we’ve opted for homemade as a way to save money and to offer to our kids as a labor of love.easy to make rainbow cake

Usually Jeff and I make the cakes together, but because of time constraints, that didn’t happen this year and I honestly think it suffered a bit, but hey, the kids didn’t notice and if the birthday girl loves it, then I’ve done my job!

I fell in love with this cake the first time I saw it because it’s just flat out fun!  I knew at some point, one of our kids would have to have a rainbow party.  Emden had a rainbow shirt that fit her this year, and so, a rainbow birthday party was decided on.  She has been looking forward to it this entire year, but I left the cake a surprise to her.

This cake ended up being easier than I anticipated because Wal-Mart had prepackaged color cake mixes I snatched up.  I gotta be honest, I hesitated pulling them off the shelf because I felt like I was cheating or something, then I came to my senses and figured why wouldn’t I want to save myself a step.


  • identical round  cake pans
  • colored cake mixes (or divide your own cake batter and color with food coloring)
  • white icing
  • skittles
  • rainbow sprinkles
  • miniature marshmallows
  • Airhead Rainbow Strips

Game Plan:

1.  Make the individual cakes. 

I didn’t have identical sizes of cake pans, so I had to do one at a time.  It didn’t take as long as I thought because after I stuck one in the oven, I started making the next cake batter so it would be ready to go.  I made all the cake layers a couple days ahead and froze the cakes to save me some time later.  I didn’t want really thick layers of cake because I didn’t want it to be a gigantically tall cake so I had cupcake liners ready to go and poured a small bit of batter into each of the 12 cupcakes.

2.  On party day, I pulled out the cakes around 10AM and the party was at 2:30.  Lay down one layer, ice on top of it, then place on the next layer, then ice on top of it, and repeat until you’re done with all of your layers.  Make sure to put the top layer of cake so that it is upside down because it will make for a smoother cake top.

3.  Cover the entire cake with white icing and smooth the icing.

I actually didn’t have time to do this step this time!

4.  Cover the top with rainbow sprinkles.

5.  Place Skittles around the bottom of the cake to create a nice border.

6.  Make a rainbow using Airhead Rainbow Strips and miniature marshmallows for clouds.

I made a triple rainbow since she was turning three.

7.  Pipe on a name or message.

8.  Take lots of pictures of everyone enjoying the cake at the party!  The real surprise is when you cut into it!
