Watermelon Popsicles

There’s nothing better than kicking back on a lazy summer afternoon with a homemade popsicle in hand. While I’m a fan of all kinds, these watermelon popsicles are my absolute favorite for beating the heat. Don’t get me wrong – I won’t say no to a chocolate popsicle, but these fruity treats are just so light and fresh.

What I love most is how simple they are to make — just three ingredients and about five minutes of prep time. Plus, you can easily jazz them up with a splash of liquor for grown-up summer fun, or keep them alcohol-free for the kids.

When the temperature climbs, these Watermelon Popsicles are exactly the snack you want on hand. Made with just three easy ingredients, a blender, and about 10 minutes of active work, you’ll end up with around 8 popsicles that are cool, light, and not overly sweet – perfect for kids and poolside chilling alike.

Keep scrolling for the full printable recipe card with exact measurements, but here’s a sneak peek: you blend, pour, and freeze. After about an hour, add your sticks, then freeze for a few more hours until they’re ready to enjoy. I also included tips for keeping them kid-friendly by swapping out lemon-lime soda, or tips for turning them into boozy treats for adults.

• Ingredients: seedless watermelon, lemon-lime soda (plus easy swaps), and a touch of sugar or honey — see the recipe card for exact amounts.
• Equipment: just a blender and popsicle molds (or paper cups and a baking sheet if you don’t have molds).
• Time needed: about 10 minutes of prep, then 4 hours freezing.
• Storage & make-ahead: freeze in molds or transfer popsicles to freezer bags or containers to keep for weeks.
• Helpful tip: always taste the blended mixture before freezing – watermelon can vary in sweetness, so you might want to add a little extra sugar or honey.

Stick around for step-by-step instructions, flavor twists, and troubleshooting tips so your watermelon popsicles turn out perfect every time.

These Watermelon Popsicles are a summer must-have for lots of reasons:

• Light, refreshing, and not too sweet — a healthy way to cool down without feeling heavy.

What You’ll Need

• 5 cups seedless watermelon, cut into 1-inch chunks
• 1 cup lemon-lime soda
• 2 tablespoons sugar or honey

How to Make Them

1. Cut the seedless watermelon into 1-inch cubes.
2. Add the watermelon cubes, lemon-lime soda, and sugar or honey to a blender.
3. Blend on high until completely smooth, about 1 minute.
4. Taste the blended mixture and add more sugar or honey if needed.
5. Pour the mixture evenly into popsicle molds and put lids on if your molds have them.
6. If you don’t have popsicle molds, pour the mixture into small paper cups set on a flat baking sheet to keep steady.
7. Freeze the molds or cups for 1 hour.
8. Insert popsicle sticks into the partially frozen molds or cups.
9. Return the popsicles to the freezer and freeze for 3 to 4 hours until fully set.

10. If popsicles are stuck in the molds, dip the molds in warm (not hot) water for 10–20 seconds to loosen them.

    

11. Pop the popsicles out of the molds or peel off the paper cups.

Pro Tips for Perfect Popsicles

If this is your first time making homemade popsicles, these tips will help them come out just right. For a tested base ratio and another watermelon popsicle variation, see our Juicy Watermelon Bliss Popsicles recipe.

• Start with less sugar and add more if you want. Watermelon sweetness is all over the place, so begin with a smaller amount of sugar (or honey), taste after blending, and add more as you like. It’s the best way to get a perfect balance.
• Pick the right popsicle mold for you. Popsicle molds come in all shapes and sizes — some have built-in sticks, others need you to add them later. Read reviews and pick what works best for your family. My photos show the type I use. Just keep in mind, mold size affects how many popsicles you’ll get.
• No mold? No problem. Grab small paper cups and pour the mixture in on a flat baking sheet to keep steady. Freeze them for an hour, then add sticks as usual. Once frozen solid, you just peel off the paper cups!

Ways to Mix It Up

This simple watermelon popsicle base is so flexible! Here are some of my favorite ways to mix things up:

• Kid popsicles. Swap lemon-lime soda for sweet white grape juice to keep these low fuss and kid-friendly.
• Boozy popsicles. For an adult twist, replace lemon-lime soda with 3/4 cup vodka (regular or watermelon flavored) plus 1/4 cup club soda. Prefer tequila? Take citrusy balance cues from this frozen margarita recipe.
• Mojito popsicles. Mix lemon-lime soda out for 1/2 cup white rum and 1/4 cup club soda, then stir in 3 tablespoons fresh lime juice and 1/4 teaspoon mint extract for a bright, refreshing Mojito flavor.

Freezing and Storage Tips

You can keep your homemade watermelon popsicles in the molds for a few days if you’re snacking regularly. For longer storage, take them out and transfer to reusable freezer bags or containers. If you stack them up, pop parchment paper between layers so they don’t stick together. Stored this way, they’ll stay fresh and tasty in the freezer for up to a few weeks.

If your popsicles are a bit stuck in the molds, dip the molds in warm (not hot) water for about 15 seconds. That loosens them right up without melting your treat.

Common Questions Answered

• Q: Can I use watermelon with seeds?

  A: Absolutely! Just trim off the rind and remove as many seeds as possible before blending. If you want a totally smooth texture, you can pass the puree through a fine sieve to catch any seeds.

• Q: What can I substitute for lemon-lime soda?

  A: White grape juice is a great substitute for the kids. For grown-ups, vodka or watermelon vodka with a splash of club soda works well, or try rum and club soda for a mojito vibe.

• Q: How much sugar or honey should I add?

  A: Start with the amount called for in the recipe, then taste your blended mixture. Add a little more sugar or honey only if you feel it needs a touch more sweetness.

• Q: Does alcohol keep the popsicles from freezing well?

  A: Since alcohol lowers the freezing point, it can make popsicles softer. That’s why I suggest keeping the amount moderate — like 3/4 cup vodka with 1/4 cup club soda — so they freeze properly but still have a boozy kick.

• Q: How long do they need to freeze?

  A: Freeze the mixture in molds for 1 hour first, then add sticks and freeze for another 3 to 4 hours, so about 4 hours total.

• Q: How do I get popsicles out of the mold easily?

  A: If they’re stubborn, dunk the mold in warm (not hot) water for 10 to 20 seconds to loosen the edges, then gently pull them out.

• Q: Can I make these without a popsicle mold?

  A: Totally! Just pour into small paper cups on a flat baking sheet, freeze an hour, add sticks, then freeze until fully set. When ready, peel away the cups carefully.

• Q: How long do popsicles keep in the freezer?

  A: When stored in a freezer-safe bag or container (with parchment paper if stacking), they keep well for a few weeks.

• Q: Can I use frozen watermelon?

  A: Yes, you can! Just thaw it enough so your blender can puree it smoothly. Don’t forget to taste and add sweetness if needed since frozen fruit can sometimes be less sweet.
