If you’re planning a rainbow or unicorn birthday party, or an upcoming holiday party, don’t miss this easy tutorial to make your own Rainbow Cake Topper! Any kid or adult would love to have it at their next party!
With St. Patrick’s Day coming up, for today’s National Craft Week post, I decided to make a Rainbow Cake Topper that you can recreate for your own cakes! It’s perfect for little leprechauns (just like this leprechaun trap cake topper) or even for rainbow or unicorn birthday parties!

This DIY cake topper is SO easy, and it only takes a few supplies. Although I love a good balloon garland, you don’t need any experience to make this rainbow!
Supplies you Need for a Rainbow Cake Topper DIY
The amount of supplies you’ll need will depend on the size of cake, but the basic supplies are:
How to Make a DIY Balloon Rainbow Cake Topper
Start by gathering your balloons and selecting the colors you’ll be using for your topper. I purchased a huge set of water balloons from Amazon, so I had a TON of extras that my kids will be using this summer.
Why water balloons? Because they are small and blow up easily to small sizes without looking strange. For this 8″ cake, I used 2 of each color – 14 balloons in all. Blow them up in varying sizes.
You’ll also need 2 skewers, 1-2 paper straws (to cover the skewers), and a piece of floral wire. I used precut floral wire because it’s what I had on hand. If you have a larger cake, you may want to go with wire that you can cut as long as you want.
Attach one end of the floral wire to the top of a skewer by twisting it around the end.
This is the really easy part – I didn’t want to risk popping the balloons by twisting the wire around the ends, so I just threaded the wire through the tails of the balloons.
I started with pink and then continued with the rest of the colors, pushing them together as I went.
You can move them around, and since you’re not twisting the wire, they move really easily and you can play with the groupings of balloons.
When you’ve secured all of the balloons, twist the end of floral wire to the other skewer.
Using floral wire that was relatively thick allowed me to manipulate the mini rainbow balloon garland a little bit to look like a curved rainbow.
Measure how much straw you’ll need to cover your skewer in the cake (leaving room for the tip of the skewer to be inserted into the cake) and trim the straws as necessary. Slide the straws over the skewers.
Insert skewers into the cake. You can then decorate the cake however you wish! I decided to add some marshmallow “clouds” and rainbow candy.
Will your rainbow-loving kid (or adult) love this cake topper? Mine certainly will! I think I’ll use it for St. Patrick’s Day and then do a twist on it for my youngest daughter’s birthday party. It is so easy!
