Mermaid Popcorn for an Under the Sea Party

With our unicorn party mix and galaxy popcorn being so popular, it was clear we needed a mermaid popcorn option. Party popcorn is an easy treat that adds a lot of fun to an event. Add it to a dessert table, to goody bags, or leave it around in bowls for snacking. Whichever way you choose to display it, mermaid snack mix adds pops of color and fun all around.

As I said in the mermaid bark candy post, these treats are also great for movie nights. The new Little Mermaid movie that’s coming out soon, and the recently released, Avatar: The Way of Water are both great movies worthy of a special snack. Or, break out some of my childhood favorites like Splash! Snack away while you relive the childhood wonder.

How to Make Mermaid Party Popcorn

Line 2 baking sheets with parchment paper and set aside.

Take 5 cups of popcorn and transfer them to a mixing bowl. A Stir Crazy popcorn maker was used for this recipe, but you make popcorn however you like, or buy a bag. Use salted popcorn if you love that salty sweet flavor, or leave it unsalted if you prefer.

If you choose to use a Stir Crazy popcorn popper, 2/3 cup of unpopped popcorn with 2T oil was perfect for this recipe. There was only a little bit left over.

In a separate, microwave-safe bowl, add one cup of one of the candy melt colors and place it in the microwave on 100% power for one minute.

Stir the candy melts until they are completely melted. If needed, put it back in the microwave for 10 seconds and stir until smooth.

What Else to Serve at a Mermaid Party

Here are some more mermaid recipes to consider if you are throwing an under the sea themed event. These also work for pool parties in general.

Baked goods: Swirly mermaid cupcakes, tide pool cookies, and mermaid cookie pizzas are all tasty additions to a dessert table.

Drinks: An icy mermaid slushy is a refreshing summer treat, or choose mermaid hot cocoa melts for the cooler months.

Candy: Mermaid fudge and mermaid bark candy are both easy and fun to make.

Ice cream: This green, purple, and blue ice cream is no-churn and a super sweet treat.

No-bake: Mermaid donut holes and clam cookies are both treats to make without the oven.

Recipe Substitutions and Variations

  • Popcorn: As stated above, you can use your choice of popcorn. Pop your own in a popcorn maker, use microwave popcorn, or buy a popped bag. Choose plain unsalted or salted popcorn.

How to Store Leftovers

Store the mermaid popcorn in an airtight container at room temperature for up to a week. It’s important to keep the popcorn in a cool, dry place, away from direct sunlight, to prevent it from becoming stale or melting.

Recipe Notes and FAQ

Can I make this recipe with less popcorn?

Yes, if you don’t need such a large batch of popcorn, feel free to use less and adjust the amount of candy melts and other ingredients accordingly.

Do I have to microwave the candy melts?

No, you can also melt candy melts using a double boiler. Wilton also makes a special pot just for melting their candy melts.

Can I use leftover popcorn?

You can use whatever kind of popcorn you like; just make sure it’s fresh. Stale popcorn will not coat well with melted candy. Plus, it just won’t taste as good!
