Rainbow Cupcakes

These are so easy to make since I just used a box mix. And they’re sooo pretty! 😍 Now, I know that using a box mix is technically cheating… But I don’t really care. It saved me time and the rainbow cupcakes still tasted amazing. Especially since I only used egg whites in my batter. Not including the egg yolks made my cupcakes insanely fluffy and a super pristine white- which made it really easy to dye the batter any color I wanted.

And I wanted a lot of colors.

Even using a box mix shortcut, these cupcakes still took a while to make. Which, frankly, surprised me. I don’t know why, but I wasn’t expecting it to be quite so time consuming to make each individual layer- but it was totally worth the effort. I mean, just look at that cupcake! It’s so happy to be alive! And that happiness is contagious. Seriously, how can you look at these cupcakes and not smile?

So, if you want something to smile about, just whip up a batch of rainbow cupcakes. They’re sure to chase any rain clouds away and leave your day a little bit brighter. And a lot more colorful. 🌈

Wanna see how I did it?

First I made the cake batter according to the directions on the back of the box. Then, I divided the batter between six different bowls. I actually used a 2/3 measuring cup to evenly divide the batter between the bowls.

Of course, I then had a little batter leftover, so my method wasn’t quite perfect. But being precise helped me portion out almost all of the batter. And then I knew I had the same amount of each color.

After my batter was divided into bowls, it was time to add the food coloring. I added food dye a drop at a time until I was happy with the color. This took a lot of guessing and a lot of stirring to see whether it was the shade I wanted or not. And when it wasn’t quite bold enough, I added another few drops, again and again, until it was bold enough.

Once I had six bowls all vibrantly dyed, it was time to make my individual cupcakes.

Unfortunately, I wasn’t as precise with my batter distribution as I should have been with this step. And, as a result, my layers are not quite as even as I would have liked. Even though I tried to use just under a tablespoon of batter for each layer, I eyeballed the amount and you can definitely tell.

But beyond the measuring, I found that spreading the batter was actually quite tricky too.

Since I didn’t want to smear any extra batter on the cupcake liner- in order to get pristine rainbow lines from the side profile- maneuvering a spoon handle proved beyond my abilities. So instead, I used a toothpick to push the batter around. And the toothpick tactic made my life a whole lot easier. Without the unwieldly handle, I had much better control over the batter. (Hooray!)

Now, as far as the order of the layers, you want to start with purple and work your way backwards through ROY G BIV.

You remember ROY G BIV from school, right? It’s the acronym that helps you remember the order of the colors in the rainbow. (Although I think they killed Indigo. But, for right now, let’s stick with all the colors, the way I learned it way back when.)

So by backwards, I mean you add the colors in this order: Violet, Blue, Green, Yellow, Orange, and lastly Red. This way, when your cupcake comes out of the oven, the red is on top. The way a rainbow is supposed to be.

Next, bake your prepared cupcakes in the oven according to the directions on the back of your box mix.

Once they’ve cooled, you get to frost them. I made sure my frosting was extra white by using clear vanilla. And, if desired, you can add rainbow sprinkles on top of the frosting. You know. Just in case anyone missed the fact that these cupcakes are full on rainbows and they need an extra hint.

Remember how I said that I did a bad job dividing my dyed batter between my cupcakes?

Well, I used up all the purple batter and still had batter leftover in other colors. So, I made some colorfully marbled cupcakes with the extra batter. They almost give off circus vibes they’re so bright. But they’re just so happy looking that I don’t really care! πŸŽͺ

Stunning Rainbow Cupcakes You Have To Try


  • Author: Mackie
  • Prep Time: 1 hour
  • Cook Time: 15 minutes
  • Total Time: 1 hour 15 minutes
  • Yield: 18 cupcakes 1x

Ingredients

Scale
  • 1 box white cake mix
  • Red, yellow, green, and blue food dyes

Instructions

  1. Make the cake mix according to the directions on the back of the box.
  2. Divide the cupcake batter into 6 separate bowls. (I used a 2/3 measuring cup to divide the batter. But this left me with a little leftover batter, so I eyeballed divvying it between the bowls.)
  3. Add food coloring to each individual bowl. You want a red, orange, yellow, green, blue, and a purple. Then arrange the bowls in that specific order on your countertop.
  4. Then start working your way backwards through the ROY G BIV set up. Start with the purple batter and pour less than one tablespoon of purple batter into a cupcake liner. Spread it evenly and try not to get any batter on the edges of the cupcake liner. I used a toothpick to help spread my batter.
  5. Repeat with the remaining colors, still working backwards through the rainbow. Continue to add as little batter as possible with each layer to keep your cupcakes from exploding in the oven. Also try to keep the colors from mixing too much or you’ll have marbled cupcakes instead of layered cupcakes.
  6. Bake according to the directions on the back of the box
  7. Remove from heat when a toothpick inserted into the center of a cupcake comes out clean. Allow to cool on a cooling rack completely before topping with frosting. If desired, garnish with rainbow sprinkles.
