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.



















Questions & Reviews
How much does the flavor of the yogurt impact the flavor of the cupcakes? And what about sour cream vs. yogurt? Just wondering about a preference for my first attempt. THANKS!!! (I am planning on trying more than one option, eventually…)
Honestly, I use all different flavors of yogurt. It doesn’t matter at all. Any fruit flavored yogurt actually tastes really good, and it doesn’t make the cake taste overly fruity at all, it’s just a different level of sweetness with a hint of flavor. Just use one that’s very light colored or it could change the outcome of the cupcake. Sour cream works great too!
I made these red, white and blue for the 4th of July, topped with white frosting and red, white & blue sprinkles. A big hit at the family BBQ!
Wow, I love them!
