Watermelon Popsicles

Watermelon Popsicles are the perfect way to cool down on a hot summer day. Give this no sugar added frozen treat a try next time you’re looking for some refreshment.

Nothing says summer quite like watermelon, and it’s the perfect time of year to enjoy this gem when it’s in season. These watermelon popsicles combine naturally sweet fruit and tangy lime with a hint of salt – to balance the flavor and for electrolytes – and a collagen protein boost.

How to Pick a Watermelon at the Grocery Store

Everyone seems to have their own method for picking the perfect watermelon at the grocery store. Here’s what to look for…

A heavy melon. For its size, the watermelon should feel heavy. That means the watermelon is juicy! A light watermelon is usually drier or mealy on the inside.

Knock on it. Give the watermelon a good solid knock on the bottom. It should sound hollow.

How to Make Watermelon Popsicles

These watermelon popsicles couldn’t be much easier to make. The only hard part is waiting for them to freeze! Here’s how to make them.

  • Cut the rind off the seedless watermelon and chop the fruit up into chunks.
  • Add the watermelon chunks to a blender along with the lime, salt, and Vital Proteins Collagen Peptides.
  • Blend on high for 15 to 20 seconds until the mixture is smooth.
  • Pour the mixture into a popsicle mold and freeze for 4 to 6 hours or overnight.
  • Run the molds under warm water for several seconds until the watermelon popsicles slide out.

I use a 10-popsicle mold (this is the one I have) to make these watermelon popsicles. If you don’t have a mold, you can use Dixie cups with popsicle sticks inserted after a couple hours of freezing time.

Adding a Collagen Boost

I love adding a collagen protein boost to these watermelon popsicles with Vital Proteins Collagen Peptides.

Vital Proteins Collagen has no flavor and it dissolves easily in cold liquids. It contains 20 grams of collagen per serving and is a rich source of the amino acids glycine, proline, and hydroxyproline.

Also, Vital Proteins Collagen is an easily digestible protein that’s naturally dairy-free. It’s also gluten-free.

If you’re looking for something with added flavor, feel free to swap in the Tropical Hibiscus or Strawberry Lemon Beauty Collagen. Those work perfectly with these watermelon popsicles.

Watermelon Popsicles Variations

This recipe is so simple, and you can easily modify it. Try one of these tasty variations on this watermelon popsicles recipe. The sweetness of your watermelon may vary. Be sure to taste the mixture and if it needs a little more sweetness, add a drizzle of raw honey or maple syrup.

Watermelon Mojito. Add six mint leaves to the blender when you puree the mixture.

Strawberry Watermelon. Use half strawberries and half watermelon. Leave out the lime juice.

Watermelon Lemonade. Instead of lime juice, swap in lemon juice. Add a touch of honey if the mixture isn’t sweet enough.

Recipe Notes

When making this recipe, I selected a small seedless watermelon that weighed about 5 pounds. To get 4 heaping cups of watermelon, I used approximately 3/4 of the melon. Please note that individual watermelons vary in terms of juiciness so you may end up with slightly more or less of the mixture. If you have more, add ice cubes and drink!
