I’m going to let you in on one of my biggest insecurities… I am terrible in the kitchen. TERRIBLE. I can manage a few of the classics:  cereal, waffles, and peanut butter sandwiches, but other than that, I have no skills.

My son recently asked if we could make “rainbow cupcakes”. It sounded like fun (and let’s be honest – I can never turn down a cupcake), so I Googled “rainbow cupcakes” and found this decorating idea from Chica and Jo. A recipe that combined baking and art? I knew I was good at one of those things (and only one) so I thought, why not?


  • Cupcakes
  • Vanilla frosting
  • Food coloring
  • Decorating supplies: decorating bags, decorating tip, and a small paint brush.

Note: We used Wilton decorating bags and a Wilton 32 decorating tip.


You can get full directions with step-by-step photos over at Chica and Jo, but here’s the concept in a nutshell:

  1. Bake cupcakes and let cool.
  2. Select the food coloring you want to use and put a small amount of each color onto a plate.
  3. Using a small paint brush, paint long lines of each color inside a decorating bag. Fill the bag with white frosting.
  4. Decorate your cupcakes!

From start to finish it took about one hour. It really was pretty simple (even for a novice like myself) and the cupcakes turned out beautifully!

The kids suggested we hand out some of our masterpieces to our family. So we threw a couple in a box, added one of our Pot of Gold necklaces for a festive touch, and delivered! (Want more St. Patrick’s Day ideas? Click here!)
