timesaving tips to streamline recipes

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 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.


Frosting For Rainbow Cupcakes
¾ cup unsalted butter
¼ cup heavy whipping cream or milk
3-4 cups confectioners’ sugar
1 teaspoon vanilla extract

Hi, I'm Raquel! I am a self-proclaimed foodie and have enjoyed cooking and baking since I was little. I loved baking cookies with my mother and grandma as a child, and later making dinners for my parents to foster my passion while in high school. I also had a passion for organizing and keeping things tidy.
