My Mom is a really creative woman. I didn’t realize it until I grew up and became a mother myself. Now that I look back on the birthday parties she threw and the incredible cakes she created, I’m really amazed at the things she came up with back in the day when you couldn’t run to Target or Walmart and basically buy a party in a bag. Halloween costumes were no exception. We never, ever had store-bought costumes growing up. My Mom was a great seamstress and her creativity had no boundaries. I look at old family pictures and I love how she took simple ideas and turned them into something fun. Take me for example, around age 5:

That my friends, is a rainbow. And I thought it was the coolest costume ever. I was obsessed with this chick, and if you look at every picture I ever created out of any sort of art media between the ages of 3 and 9, it undoubtedly included 3 things: hearts, flowers, and rainbows. To this day, I still get a little bit giddy inside when I see all of those colors together. Something about rainbows just makes me happy.
So it’s no wonder these cupcakes make me smile. Every time 🙂
Gel food colors work especially well for this. Gel color adds a ton of color with a small amount of dye. You can find gel colors at craft stores like Michaels and Roberts, and in the cake decorating isle of Walmart. If using red, make sure to get the one that says “No Taste”
Divide your batter and tint each one
Then layer it by color into the cupcake papers. (See my tips in the recipe for easy layering). Sometimes I do red on top and sometimes I do the reverse so blue is on top.
Bake them up
And cool them on a rack before frosting.
Then you can frost and decorate to your heart’s desire!
The best part comes when you peel off that paper. Use white liners to show off the colors, or foil or dark liners to make it a surprise!
Even better is taking the first bite and seeing the inside:
Try them with the color of your favorite sports team, or your kids’ school colors. They’re sure to be a hit!
Colorburst Cupcakes
1 white cake mix
2 eggs
1 C yogurt (any smooth textured fruit flavor is fine!) or sour cream
1/2 C milk
1/3 C vegetable oil
Combine all ingredients until incorporated (about 30 seconds). Scrape sides of bowl and then beat on med-high speed for 2 minutes.
Divide batter according to how many colors you are using. I used 5 colors and it worked out to a little over 1 cup for each color, but each cake brand will be slightly different.
Use food coloring to color batter to desired intensity.
To get a layered stripe like I used, you’ll want to put a spoonful of each color in the cupcake one at a time. The batter is thick, so it won’t spread on it’s own. A great tip is to set out a little bowl of water where you’re working. Dip your finger in the water and then gently spread the batter out. The water will make it so the batter doesn’t stick to your fingers.
Another tip is to use a measuring spoon and some water to measure out how many teaspoons/tablespoons are going to fit in your cupcake. Then divide that by how many colors you have so you know how much of each color to use for each cupcake. For my 5 colors, it worked out perfectly with 2 t of each color in each cupcake. So I put in 2 t of blue in the bottom of each cupcake and spread it out with my finger. Then I put in 2 t of green on top of that, then yellow, etc.
Bake them according to the package directions, until a toothpick comes out dry.
I topped mine with this frosting.

I am SO glad I found these cupcakes! My daughter will love this. I am going to try it with one large cupcake cake pan for her birthday in May!! Thank you for sharing!
We made these today to celebrate St. Patty's day. These represented the pot o' gold at the end of the rainbow 🙂 Thanks for sharing.
Gorgeous cupcakes! I saw this on family fun too, but I think I will try your cupcake recipe instead of just a regular box mix. The swirls you put on top look great! Thanks for sharing this!
I made these but with neon food dye… they turned out amazingly epic! I ended up bringing these around to a couple bars and people LOVED them! Best birthday cupcakes ever!
I love this idea. This is so simple but SO impressive!
Cupcakes are my thing!! Love these! Might be just what I do for for littest ones first b-day later this month!
Oh wow…Thank you so much! You've really helped me out!
Nik, you can bake and frost them tonight, just store at room temp and you should be good to go!
Hi There!
I have been so excited to make these for my sons first birthday. I have been waiting about a month and now the day is here and I am a little nervous. I am not really the baking or cooking type but since my son has been eating table foods I have developed a real love for it actually. Anyway, that being said I need some advice. I would like to make these tonight for his party tomorrow. Yeah, I'm a little late on the nervousness…probably should have figured this out a while ago. : ) I am going to make the recipe as it is on the box and I am making both regular size and minis using the Wilton Gel Color. Probably 12 regular and then however many left in minis. My questions are, what is the best way to do these in advance? Is there a best way to store them? Should I make the frosting the night before? Should I frost the night before? 😀
Sorry for all the questions….I just really want it to turn out well. Any advice would be so appreciated.
Also I have to say, I love this site. I have found so many fun things I would like to try!
Thanks so much in advance!
Oh, and I am going to use the frosting you put on them too. I've been looking for a light frosting that is like my local cupcake bakery without having to spend a fortune. 😀
ever thought of putting a mini marshmallow into the cupcake and baking it? ..just wondering if anyone has ever tried it!
