How to Make Watermelon Popsicles

This watermelon popsicle recipe couldn’t be easier to make! You’ll need two simple ingredients:

Fresh watermelon – I call for 6 cups cubed, from about 1 medium melon. Not sure how to chop it? Check out my guide to how to cut a watermelon!
Lime juice – Its bright flavor adds such a nice kick to these popsicles! Use freshly squeezed lime juice for the best taste. Fresh lemon juice works too.

FAQ: How do I choose a good watermelon?

Look for a melon that’s heavy for its size.
Check out the “field spot.” This white or yellow spot is where the watermelon made contact with the ground while it was growing. A darker spot indicates a riper melon. Chose a melon whose spot is yellow or cream-colored, not pale white.
Knock on it! A ripe melon will make a hollow sound.

Place the watermelon and lime juice in a blender and blend until completely smooth.

Pour the watermelon mixture into popsicle molds, leaving 1/2 inch of space for expansion at the top. Cover, and add popsicle sticks if they’re not built into your molds.

Finally, freeze the popsicles until they’re set, 4 hours or overnight.

Yes, it’s that easy to make these homemade watermelon popsicles!

Variations

Our family loves this recipe as written, but by all means, feel free to change it up!

Use a combination of fruits. Part watermelon and part strawberries would be great.
Or use a different fruit. I’m trying mango popsicles next!
Add an herb. Fresh basil or mint leaves would make these ice pops even more refreshing.
Make them creamy. Blend some whole milk Greek yogurt or coconut milk into the watermelon puree.
Sweeten them. To make these homemade popsicles extra-sweet, add your desired sweetener, such as honey, maple syrup, or cane sugar, to taste.

Best Watermelon Popsicles Tips

Recruit the kids. These easy watermelon popsicles aren’t just fun for kids to eat—kids can help make them too! Have them stop and start the blender, or let them add the popsicle sticks to the molds. My son and I love making this recipe together!
Use a seedless watermelon. That way, you can add the watermelon straight to the blender after you chop it. If your watermelon has seeds, do your best to remove them from the melon before pureeing it—they add bitterness to the watermelon mixture.
Leave room for the popsicles to expand. Liquid expands in the freezer, so make sure not to fill your popsicle molds all the way to the top. I leave 1/2 inch at the top of mine to give the watermelon popsicles room to grow.
Eat them within 3 months. If your family is anything like ours, these watermelon popsicles will disappear like lightening. But if you happen to have some hang around, they keep for weeks in the freezer. Aim to polish them off within 3 months for the best flavor.
