Why We Love These Watermelon Mint Popsicles

Honestly, it’s hard not to love these. They’re:

🌱 Naturally sweet – thanks to ripe watermelon, there’s no need for added sugar.
💸 Budget-friendly – a single watermelon goes a long way, and mint is easy to grow or snag for cheap.
⏱️ Quick to make – 10 minutes of prep and your freezer does the rest.
🍋 Bright and zesty – lemon juice adds the perfect contrast to the sweet watermelon.
❄️ Freezer-friendly – make a batch ahead of time for guests, or just to treat yourself.

If you’re trying to eat a little cleaner this summer or want a fun project to do with kids, these are perfect. You can even pour the mixture into ice cube trays to make watermelon-mint ice cubes for your cocktails or mocktails!

Ingredients

Here’s what you’ll need to make 1 litre of popsicle liquid (enough for about 8–10 standard popsicle molds depending on size):

Watermelon – enough to yield 1 litre of juice after blending (roughly 4–5 cups of cubed watermelon, about 1.5 kg or 3–4 lbs)
Juice of 1 lemon – for brightness and balance
A handful of fresh mint leaves – about 10–15 leaves, depending on how strong you like it

📝 Optional: If your watermelon isn’t super sweet, you can add 1–2 tbsp of honey or maple syrup, but we usually skip it!

Freezer space!

Let’s Talk Texture

Here’s the deal: once everything is blended, you’ll end up with about 1 litre of watermelon-mint-lemon goodness. You get to choose your popsicle texture:

Rustic: Keep all the pulp and bits of mint for a bold, vibrant popsicle. It’s slightly slushier and very “homemade” in the best way.
Smooth: Strain the mixture using a fine mesh sieve or cheesecloth to remove pulp and mint bits. The result? A smooth, almost sorbet-like popsicle with a more subtle flavor.

📌 Either way, make sure your final liquid (after blending and optional straining) equals 1 litre to fill your molds properly.

How to Make Watermelon and Mint Popsicles

Step 1: Cube and Blend the Watermelon

Remove the rind and cube your watermelon. Add it to a blender with your mint leaves and blend until totally smooth. Add half the lemon juice and blend again for 5–10 seconds.

🍉 TIP: If your blender has trouble with a thick blend, add a splash of water to get things moving.

Step 2: Taste Test & Adjust

Before you strain, give your mixture a taste. Want it sweeter? Add a touch of honey or maple syrup. Need more brightness? Add more of the lemon.

Step 3: Strain (or Don’t!)

If you prefer a smooth popsicle, pour the mixture through a fine mesh strainer into a large measuring cup until you reach 1 litre of liquid. If you love pulp and don’t mind mint flecks, skip this step and measure your unstrained liquid to ensure you have 1 litre.

✅ NOTE: If you end up with less than 1 litre after straining, you can top it off with a bit of water, more blended watermelon, or even a splash of fruit juice (like coconut water or limeade!).

Step 4: Pour and Freeze

Pour the mixture into your popsicle molds. Don’t fill them completely to the top—leave a little room for expansion as they freeze. Insert sticks and place in the freezer for at least 5–6 hours, ideally overnight.

Step 5: Unmold and Enjoy!

To easily remove the popsicles, run the outside of the mold under warm water for 10–20 seconds. Gently wiggle the sticks to release.

Now grab a towel, head to the patio, and enjoy your homemade summer on a stick. 🍧

Variations and Add-Ins

Feeling creative? Here are a few ways to remix this recipe:

Basil instead of mint – for an herbaceous twist
Add coconut milk – swap ¼ cup of watermelon with full-fat canned coconut milk for a creamy treat
Add berries – drop a few blueberries or raspberries into each mold before freezing
Spike them – for adult popsicles, add 1–2 tbsp of vodka or white rum (just be aware this may slightly affect how well they freeze)

How to Store Homemade Popsicles

Store your popsicles in the molds or transfer them to an airtight container with parchment between layers once frozen. If you’re using the molds like the ones we linked above, be sure to always replace the top cover when putting it in the freezer to keep the bottoms of your popsicles from getting freezer burnt. They’re best within 2–3 weeks for peak flavor, but still safe for longer.
