There are a couple of cakes that I make that the kids go crazy over. This rainbow cake it one of them!
I made it for the first time when Nick and Luke turned 4. Um, they just celebrated their 12th birthday recently and THIS cake is one they ask for often.
The only thing is, it is tedious and timely to make. And honestly, it is kind of messy. So last week when I made it as a surprise, everyone’s eyes lit up. They know, when I start breaking out the Skittles, multiple cake pans and TONS of icing, they know what’s coming.
Let me show you how we make this. I don’t want to discourage you when I say it is messy and time-consuming, but I just want, to be honest. Nonetheless, it is an amazing time to make memories together and it is a great opportunity for homeschooling because there are some math and life skills that go into this cake. Plus, who does not love a rainbow!

Here is the year they turned 4 and we made this cake. I know it’s not a large picture and it is not one you will likely see on Pinterest, but it is our memory. My sweet babies are not babies anymore.
Ingredients:
- 2 boxes of white cake mix
- ingredients on the back of the box for the cake mix
- 1 box of multi-color icing dye (you will use ROYGBV)
- 1 batch of homemade buttercream icing (or you can buy this)
- 3 round cake pans (6 if you want to buy that many) just make sure they are all the same size
- 1 pkg of cake wooden dowels
- 1 bag of small marshmallows
- 1 large bag of Skittles
- 1 roll of Bounty paper towels (trust me, you will need them)
In a standing mixer, mix up the two boxes of white cake mix following the instructions on the back of the box using the listed ingredients (water, oil and egg, usually).
Once the cake mix is mixed well, divide the mixture up into six smaller bowls. We did about 1 and 3/4 cup of cake mix per bowl.




Once I have iced it I like to use a wet Bounty paper towel and wipe the edge of the cake plate to make it clean and pretty.

Next, separate out your Skittles by color.
Then add them in the shape of a rainbow on top and use small marshmallows to make the shape of clouds underneath.

Is this not the most adorable and fun cake ever?!?!

Here is the one I made on their 4th birthday. I added Skittles around the top and bottom as well.

It’s the cake that brings a smile to everyone’s face!!

Here is the one I made way back in 2010. This one goes from red to purple instead od purple to red when you cut into. Honestly, the kids don’t care either way!
Enjoy… then prepare yourself for an adult sugar coma and stomach ache as your children rage in hyperactivity and bounce off the walls.
Totally the best birthday cake EVER! (But I already said that.)
