Ingredients for watermelon mint popsicles
- 4 cups watermelon juice
- 1/2 cup sugar
- 2 tablespoons fresh mint leaves
- 1 tablespoon lemon juice
- 1 teaspoon agar-agar powder
- 1 cup coconut milk
- 1/4 teaspoon salt
- 1 teaspoon vanilla powder
- 1 tablespoon honey
- 1/2 cup water
- 1 teaspoon lime zest
Fresh watermelon juice makes all the difference in these watermelon mint popsicles. I use a blender to puree fresh watermelon, then strain it through cheesecloth (yes, I know it’s an extra step, but it keeps them smooth and gorgeous).
Can’t find agar-agar? Gelatin works fine as a substitute, though the texture will be slightly different. Skip the coconut milk if you’re not a fan—these work great with just the watermelon and mint base alone.
Step-by-step instructions
1. Pour your 4 cups of watermelon juice into a blender with fresh mint leaves and blend on high for 30 seconds. Strain through a fine mesh sieve into a large bowl, pressing gently on the mint. You’ll have a beautiful pink juice that smells amazing. Don’t skip the straining—it keeps the texture silky.
2. Combine the 1/2 cup sugar, agar-agar powder, and 1/2 cup water in a small saucepan over medium heat. Stir constantly until it reaches 160°F on your thermometer, about 3 minutes. This activates the agar-agar so your popsicles freeze solid. Remove from heat and let it cool for 2 minutes.
3. Pour the agar mixture into your strained watermelon juice and whisk together until completely smooth. Add 1 tablespoon lemon juice, lime zest, and salt. Taste it—honestly, I always taste mine to make sure the tartness is right. Add a splash more lemon if you want it tangier.
4. In a separate bowl, whisk together the coconut milk, 1 teaspoon vanilla powder, and honey. This creamy layer makes them extra special. Pour this mixture very slowly into your watermelon base while whisking gently—don’t go crazy or you’ll get all mixed together.
5. Let the mixture cool to room temperature, about 15 minutes. Pour into your popsicle molds, filling each one about 3/4 of the way full. Leave a little headroom because they expand slightly as they freeze. Insert sticks gently and place on a level shelf in your freezer.
6. Freeze for at least 4 hours before removing from molds. I usually make mine in the morning and they’re ready by dinner. If they stick in the molds, run warm water over the outside for 30 seconds and they’ll slide right out.
7. Store your frozen watermelon mint popsicles in a freezer bag for up to 2 weeks. They’re perfect for grabbing on hot days or tossing into a cooler for outdoor adventures. Mine never last that long though—they’re gone in days.

Pro tips for perfect watermelon mint popsicles
Storage tips
– Keep extras in a freezer bag with parchment between each one so they don’t stick together – They last up to 2 weeks frozen but honestly taste best within 10 days – Don’t store near strong-smelling foods—they absorb flavorsMake-ahead instructions
– Blend and strain the watermelon base the day before, cover and refrigerate – Prepare the agar mixture in the morning, let cool completely before pouring into molds – Assemble and freeze the night before your party for zero-stress entertainingVariations
– Swap mint for basil for a totally different vibe—sounds weird but tastes incredible – Add 1/4 cup crushed strawberries to half the batch for a pink ombré effect – Mix in tajín seasoning for a spicy-sweet kick that guests always loveTroubleshooting
– If they’re too icy and hard, thaw for 2 minutes at room temperature before eating – Didn’t freeze solid? Your molds might not have sealed properly or your freezer’s too warm – Texture grainy? You skipped straining—it happens, just blend smoother next timeFrequently asked questions
How long do watermelon mint popsicles last in the freezer?
They’ll keep for up to 2 weeks in an airtight container, though I’ve found they taste best within 10 days. After that, ice crystals start forming and the texture gets a little grainy. Store them in a freezer bag with parchment between each one so they don’t stick together and get damaged when you pull them out.
Can I use frozen watermelon instead of fresh?
Yes, frozen watermelon works great—just thaw it completely and strain out excess liquid before blending. The flavor will be just as good, and honestly it’s more convenient for busy people. I’ve made these with frozen watermelon from Costco and nobody could tell the difference.
What if I don’t have agar-agar powder?
Regular gelatin works fine as a 1-to-1 swap, though the texture will be slightly softer. You’ll follow the same dissolving steps and end result is nearly identical. Some people prefer gelatin because it’s easier to find at regular grocery stores.
Are these popsicles actually lower in calories than store-bought?
These run about 95 calories each because we’re using real fruit juice and minimal added sugar. Store-bought popsicles often have high fructose corn syrup and artificial colors, so these are way better for you. The coconut milk adds healthy fats that keep you fuller longer too.
