Rainbow Cupcakes & Whipped Cloud Frosting

We’re giving Rainbow Brite a run for her money with these adorable cupcakes. Just look, they’re so pretty and colorful. We made these cupcakes for a friend’s 20th birthday since they match her bright and bubbly personality. These cupcakes are the perfect complement to any little girl’s (or a big girl who still wants to be young at heart) special day. They also make for a super fun, kid-friendly activity.

Oh and let’s talk about the frosting, which is nothing short of amazing. It’s light and airy and simply delicious. Also, it’s not just for cupcakes. You can use it as a fruit dip, a layer between cakes, or on it’s own with a spoon (which we do often).

Rainbow Cupcakes & Whipped Cloud Frosting


  • 1 box of white cake mix (make sure to read the instructions on the back. The instructions will normally call for additional ingredients such as eggs, oil and water)
  • food coloring
  • 1 box of instant vanilla pudding mix
  • 1 cup of cold milk
  • 1 8 oz. tub of Cool Whip
  • sprinkles for garnish


Make cake mix as directed on the box. Divide the batter evenly between three bowls. Use the chart below, pick out three colors to make your rainbow cakes. Mix each of your bowls until the desired color forms. Always start with a very small amount of color, adding in a little at a time until you achieve the desired color. Remember that the colors will deepen over several hours.

Preheat your oven to as directed on your cake mix box. Decide which order you would like your colors to appear. Start with your bottom color. Spoon about 1 tbsp. of that color into each cup until all 24 cupcake cups have the same amount. Move on to your middle color and follow the same method. Finish with your final top color. Place in the oven and bake as directed on the box. Remove the cupcakes from the oven and allow to cool on a rack for about 2 hours. Frost cupcakes as you wish by using a pastry knife or piping bag. Finish with a dusting of colored sprinkles. No colored sprinkles on hand? You can actually make them yourself by coloring regular sugar with food coloring.

Cloud Frosting: 

To a small prep bowl, add the pudding mix with 1 cup of milk. Whisk until it begins to thicken. Fold in the entire tub of Cool Whip (a couple scoops at a time). Allow to set up and chill for at least 30 minutes. Top cupcakes with frosting and chill until ready to serve.
