How to Make Rainbow Cupcakes
Step By Step Instructions
- Make cake mix according to instructions in a bow. Beat on medium speed with spoon or electric mixer.

- Add small dollops of each color to the prepared baking cups.
- Bake cupcakes for 13-15 minutes or until a toothpick comes out clean.
- Let cool completely, then frost cupcakes with buttercream frosting once cupcakes have completely cooled.
- Pipe dots (for the clouds) and then add the candy rainbow to each cupcake.
Pro Tips and Timesaver Shortcuts
- You should be able to get 2-3 rainbows from one strip. Scissors work beat to cut candy.
- If your rainbows won’t stand up the strip is too long and needs to be trimmed.
- If the strip is the perfect size you may need to just add a little bit of frosting to the outside of the rainbow to make it stand
Variations, Notes, and Substitutions
- You can add gold sprinkles or a gold wrapped candy at the end of the rainbow.
- You can make Pastel Rainbow Cupcakes by using small amounts of food coloring.Try with a drop or two.
- You can also skip coloring the batter and just add the clouds and rainbow toppers to frosted cupcakes. You can also add rainbow sprinkles to the inside of the batter.
Serving and Storage Suggestions
- Store leftovers in an airtight container.
Freezing Tips
You can freeze unfrosted cupcakes in a ziploc bag in the freezer, once they have cooled.
To defrost, simply place in the oven or microwave until at room temperature.
