If you’re looking to add a rainbow of colors to a St. Patrick’s Day party, baby shower, unicorn party, wedding shower, Easter gathering, or another magical event, this is a fun way to display and serve popcorn.

Unicorn popcorn is another colorful option to consider for your next happy event. If you don’t need all the colors and sparkles, give this sweet and salty popcorn recipe a try for your snacking needs.

Sweet and Salty Rainbow Popcorn

A Stir Crazy popcorn popper was used to pop the popcorn for this recipe. Of course, you can pop the popcorn how you normally do.

A dash of salt on the plain popcorn before mixing it with the sweet candy melts make this snack mix a wonderful blend of salty and sweet.

Notes and Tips

Exact colors of the candy melts used were Bright Pink, Orange, Yellow, Vibrant Green, and Blue.

Keep some plain popcorn out if you plan to make clouds.

I weighed out 5 ounces of each candy melt on a scale, but this isn’t necessary.

You can simply use half of the bag, the coverage on the popcorn just might be more or less than pictured.

To avoid getting several baking sheets dirty, use one mega sheet and create layers.

Prep Time 30 minutes
Total Time 30 minutes


  • 25-30 cups of popped popcorn (you need 5-6 cups per color. If making a rainbow, you'll need a separate few cups for the white "clouds")
  • 5 oz bright pink candy melts
  • 5 oz orange candy melts
  • 5 oz yellow candy melts
  • 5 oz vibrant green candy melts
  • 5 oz blue candy melts
  • pastel Sixlets (optional)


  1. Place each candy melt color in a separate microwave-safe bowl. Microwave for 60 seconds on 50% power. Mix well. Return to microwave, in 30-second increments at 50% power and mix well. If necessary, return to the microwave for an additional 30 seconds at 50% power and mix until smooth.
  2. Pour over popcorn and mix well. Continue to mix well to evenly distribute the color. You'll need to really mix this for the color to distribute well.
  3. Pour onto prepared baking sheet. Let set until candy melts are hard, and continue on to repeat with the additional colors.
  4. To make a rainbow, lay colors in rainbow order on a serving platter or large cutting board. Add plain popcorn for the clouds.
  5. To make a unicorn mix, add popcorn to a large bowl and mix well. Sprinkle with candies and serve.


I used a Stir Crazy popcorn popper to pop the popcorn. You can pop it however you normally make popcorn.

If you use a large baking sheet, you should be able to fit two colors in a row. Add a sheet of waxed paper to create another layer. This is to avoid dirtying several baking sheets!
