Healthy frozen watermelon lime popsicles are a cinch to make and are a refreshing, naturally hydrating summer frozen treat. These watermelon popsicles are also a great way to use up leftover or overripe watermelon.
The watermelon popsicles (or watermelon ice cubes) can be made with just watermelon and lime juice - adding coconut water is optional. You can also leave the lime juice out if you want; plain watermelon popsicles are still fruity and delicious!

Blended watermelon is a refreshing treat that only takes a few minute to make, plus 2 hours or so to freeze.

Tools Needed to Make Popsicles or Ice Cubes
- Blender
- Silicon ice-cube tray or popsicles molds
Silicon ice-cube trays make it easier to release the ice cubes when they're frozen. Also, kids love making ice cubes in fun shapes! Just Google, "silicone ice cube tray shapes" and you'll find lots of options.
You can also make popsicles instead of ice cubes. Just pour the watermelon juice into popsicle holders.
Step-by-Step Instructions
For detailed instructions & ingredient amounts see the recipe card at bottom of post.
Step 1: Cut watermelon into squares. Start with about 3 cups of cubed watermelon. Puree the watermelon in a blender for less than 1 minute, until it looks like juice. Adding lime juice (¼ cup) and/or coconut water (½ cup) is optional.
Step 2: Pour the watermelon juice into popsicle molds. Freeze for 2 to 3 hours, until solid. There is no need to strain the juice unless there are seeds.
Step 3: Instead of popsicle molds, you could also freeze the watermelon juice in silicone ice cube trays.
Step 4: Enjoy!
Recipe Tips
- Seeds: If the watermelon has black seeds, you'll need to blend slowly on a low speed to avoid chopping up the seeds. You can then strain the seeds out by pouring the juice through a mesh strainer or a colander.
- Easy to Pour: Use a container with a small spout (like a glass measuring cup) to pour the watermelon juice into the ice cube trays.
- Make juice, too! Blend a little bit of extra watermelon juice so you can drink it while you wait for the popsicles to freeze!
- Ice cube trays: If you're making watermelon ice cubes, then silicone ice cube trays work best. It's easier to release the ice cubes from silicon trays and they come in all sorts of fun shapes.
