Rainbow Bright Cupcakes

Rainbow Cupcakes

March is here and this weekend I thought I would work on something cute and sweet for St. Patrick’s Day. Shamrocks, leprechauns, pots of gold, maybe? But then I was bored … none of those things really inspired me for some reason. I just wasn’t feeling green treats so much I guess. Instead I was feeling full of color. So I decided on rainbows … and cupcakes … minus the pots of gold at the end.

Mr. Sprinkles

I was also feeling like rainbow colored sprinkles … in my cupcakes.

I love these delicate jimmies by Mr. Sprinkles. (I love these even better, but the pastel colors aren’t available anymore. I’m still very upset about it. I could use them forever. For everything.)

Oh well, the rainbow sprinkles will work great for this bright little cupcake.

Rainbow Sprinkles

You’ll just need a couple. ; )

Cupcake Batter

Stir them in the batter and bake away.

Taste the rainbow.

Cupcakes … Yum!

Rainbow Cupcakes

And so bright and cheery.

But for this project we need sugar cookies, too… so we can easily cut out rainbows to the right round size and shape.

Cookie Cutouts

Use two different size circle cutters for the cookies. I used a 2 1/4-inch round cutter and the bottom end of a 1M Wilton decorating tip to cut out the center.

But any round sharp-edged shapes you have on hand can work. Try using the cap to your sprinkles containers for instance. More on that below…

Cookie Cutouts

So to make the rainbows, I cut 2 1/4-inch circles, cut out the centers and then just cut off the bottoms so they could stand easily in frosting.

In the pic above, I tried two different center sizes. I liked the larger opening better.

After the cookies are baked and cooled, they can be covered with fondant.


Roll out white fondant and then cut out circles using the same size round cutters used for the cookies. Apply a thin layer of frosting to the top of the cookie and then place the fondant shapes right on top to secure.

Painting Rainbows

Cut off any excess so your fondant shape matches your rainbow cookie shape.

And then it’s time to color. The fun part. For me anyway. I’m much better with a pen than directing icing from a tip in a smooth line, so this is right up my alley. Plus it’s pretty quick and less messy.

I used these Americolor Gourmet Writing Pens that I often use on pops. They work really great on fondant, so I think you’ll have fun with them.


First, make marks for each color so you can get a sense of how thick the lines need to be so each color is equal.

Start with red on the outside and draw even lines with each color until you reach the center.

Pretty cute.

Rainbow Cupcakes

But even cuter in the clouds.

Frosting clouds

To make the frosting look puffy, use a decorating bag fitted with an Ateco 807 tip and pipe large random dots of frosting around the edge of the cupcake. Use a knife to smooth out the sides and push the frosting up slightly so it looks like the clouds are bursting out of the cupcake liner.

Sprinkle a little powdered sugar on top so the frosting looks fluffier … plus it will create a barrier so you can gently shape the clouds. Pat down any peaks with your fingertip and use a toothpick to help define the clouds.

Rainbow Cupcakes

Fluffy and puffy.

Cookie Cutouts

So these are some smaller circles I also made sugar cookies with. I used the bottom of a sprinkles cap because I didn’t have the right size cutter and for the center, I used the top of the Ateco 807 decorating tip.

I originally thought these would be the cupcake rainbow toppers, but they were just too small, so I did something else with them.

Rainbow Cookies

See… too little. They’d be great on mini cupcakes though.

After seeing how cute the puffy clouds on the cupcakes looked, I wanted to use them on the cookies, too.

So, I colored in about 2/3 of the rainbow.

Rainbow Cookies

And added frosting to the rest using the same technique for the cupcakes.

Too cute.

Rainbow Cupcakes

Servings: 24 cupcakes



  • 2 2/3 cups all purpose flour
  • 1 1/2 cups sugar
  • 1 Tbsp baking powder
  • 4 egg whites
  • 1 cup whole milk
  • 1 Tbsp vanilla
  • 2/3 cup salted butter, softened
  • 1/3 cup rainbow sprinkles


  • 1/2 cup butter, softened
  • 1/2 cup shortening
  • 1 tsp vanilla
  • 4 cups powdered sugar
  • 4 teaspoons milk
  • extra powdered sugar for dusting


  1. Preheat oven to 350 degrees and line cupcake tin with baking cups.
  2. Sift flour, sugar and baking powder into a large mixing bowl and then mix together on low.
  3. In another bowl, stir egg whites, milk and vanilla together.
  4. Add butter to the flour mixture and mix together. As it starts to combine, slowly pour the milk mixture in and mix until completely combined. Stir in rainbow sprinkles.
  5. Fill baking cups a little more than halfway. Bake for about 16 minutes or until done. Remove and cool. Makes about 24 cupcakes.
  6. For frosting, beat butter, shortening and vanilla together. Add sugar slowly and beat until combined. Scrape down the sides and add milk. Mix until smooth and creamy. Note: Double the recipe if you will be frosting all 24 cupcakes like the pictures above, because I piled it on.

To decorate, you’ll also need:

  • 24 sugar cookies – You can use the recipe from this post. 1/2 of the dough will make about two dozen cookies and you can freeze the rest for another time. Note: You can also make and decorate the cookies ahead of time.
  • 2 1/4 inch cutter and Wilton 1M icing tip or similar size round cutters
  • Fondant
  • Americolor Gourmet Writing Pens
  • Ateco 807 or Wilton 1M Tip with decorator bag and coupler to pipe the frosting
  • Toothpicks

Rainbow Cupcakes

And just so you can get a little more of a St. Patrick’s Day feel with these… look how just changing the background makes a difference. Sprinkle a few Rolos candies or gold wrapped chocolate coins on the tabletop and you’ll be set for the seventeenth.

Enjoy! I hope you brighten someone’s day with these.

P.S. What’s your favorite St. Patrick’s Day sweet? Mine is probably these simple and addictive little truffles. As a matter of fact, I may need to go make some right now.

Update: I found these awesome gold wrapped chocolate coins at the Fresh Market this weekend. They’d look great with these cupcakes.

Hey Cindy – I know. I so wish they would make their original colors again.

Mannie Tam – Thanks – I might even like them best. They were a last minute decoration and came out pretty cute.

OMG! these are adorable!! I love them!! I just ordered some americolor food coloring today because i keep hearing how amazing it is!! cant wait!
I had a question though.. when using milk in frosting.. do u need to refridgerate the frosting?? or is it fine to leave out?? I have never known what to do so i either leave the milk out of the recipe or refridgerate.. just to be safe.. what would u recommend??

These are sooooo cute :). My only thing is fondant never works for me – maybe I’ll try royal icing.

For St. Patrick’s Day – it may be the time of year but I like anything chocolate mint! Like the Andes mints you get at restaurants or Thin Mint Girl Scout cookies. We even did chocolate cake, cake pops and dipped them in dark chocoalte mint candy melts – to die for lol.

Lantana said...

i LOVE these! Call me crazy, but my favorite St. Patty’s Day treat is those fluffy sugar cookies with super sweet frosting. Every one else I know thinks that they are too sweet, but I love them! I also love green-tinted bagels from my local bagel place. BUT….my new favorite treat might just be these cupcakes!

Seanna Lea said...

I love that you call them jimmies. My husband hates that term. To him Jimmy is a person always. So, of course, I bought him Just Jimmies ice cream and he had to mod the container to say sprinkles.

I love irish potatoes as a sweet. They are made from cinnamon, coconut and sweetened condensed milk and are pretty tasty. I get mine at the local chocolate shop right around this time of year.

Oh, these are so adorable! For some reason, these reminded me of Rainbow Brite.

Looks amazing!

Do you think I’d need to double the recipe to make 2 8″ layers of cake?

March 5, 2013 01:49 PM
Jennifer said...

I say this every time, but you have outdone yourself! Those are magnificent and I like the idea of scattering gold colored Rolos around them. I also wonder if seven minute frosting would work for the clouds since it has a marshmallowy type consistency. I don’t really have a favorite St. Patrick’s Day sweet, I usually make soda bread, but last year we made a cake with a rainbow baked inside. Check it out here: link to milkandcherries.blogspot.com

Love these but have a few tips on the icing.. I use 3/4 cup unsalted butter and only a 1/4 cup of shortening. I also use 10% cream instead of milk ane use a sprinkle of fine sea salt. I also use 1/2 tsp of each vanilla and butter flavoring. It is so yummy. Some times I leave out the vanilla and it makes for a creamy flavour icing.

Bakerella said...

Thanks everyone!!!

Decadent Diva – Giant YAY! So glad they enjoyed the toy.

Linsey – I leave it out of the fridge.

icakepops & Winnie – love how the p. sugar makes them look softer. Sometimes the frosting can be shiny.

Marica – Thanks

Jo and Sue – Sounds great!

Thanks Bridge!

Lantana – not crazy

Brenda – I was a professional colorer.

Seanna Lea – Bridget from Bakeat350 just made some of those.

The vanilla bean – I don’t think so

Rachel – it does sound yummy.

These are absolutely adorable. I’ve been trying to think of ways to make rainbow cupcakes – finding rainbow colored strip candy and such, but making them out of cookies is so much better!

Marie M.C. said...

So cute. Love your creative streak. Question: I have a recipe for frosting that calls for 4 cups of powdered sugar which I assumed was equivalent to 1 pound. Just to make sure I googled and guess what — all kinds of different answers. (The explanation on the box confused me even more. Sounds like it would be 1/4 cup less then 4 cups.) What do you use. Same problem with AP flour. I’m always concerned when I make a cake that the flour is measured correctly. The given weight is all over the map too. 4 oz. in one cup? 5 oz.? Help! p.s. I bought a scale when something I made tasted off and I thought maybe I’d measured wrong. In Europe recipes are in weight rather than volume and it sounds like a more accurate system. How do you measure flour? sugar? Thanks!
