Two-Ingredient Watermelon Ice Cream (No-Churn!)
This light, refreshing two-ingredient watermelon ice cream is the easiest summer dessert you’ll ever make—just frozen watermelon and coconut milk blended into creamy, naturally sweet perfection.
I stumbled onto this recipe last summer when I had way too much watermelon taking up fridge space and not enough freezer room for a proper ice cream churn situation. Turns out, frozen watermelon transforms into the most incredible soft-serve texture when you blend it up with just a splash of something creamy. It’s become my go-to when it’s too hot to think about turning on the oven.
The best part? You probably already have everything you need, and the actual work takes about five minutes. The hardest part is just waiting for the watermelon to freeze.

Why You’ll Love This Two-Ingredient Watermelon Ice Cream
This isn’t just another fruit-based frozen dessert that tastes like flavored ice chips. When you blend frozen watermelon properly, it actually gets smooth and creamy—kind of like the texture you’d get from a fancy soft-serve machine.
It’s naturally sweet enough that you don’t need added sugar, which is rare for homemade ice cream. The watermelon does all the heavy lifting flavor-wise, and you just need something creamy to smooth everything out and give it that real ice cream mouthfeel.
I love that it’s flexible too. You can use coconut milk for a dairy-free version, yogurt if you want extra protein and tang, or sweetened condensed milk when you’re feeling indulgent. All three work beautifully, just with slightly different results.
And if you’re into quick frozen treats, you might also enjoy my protein ice cream recipe or the viral butter-dipped ice cream everyone’s been making.

Instructions
- Freeze the watermelon cuber in a single layer on a piece parchment paper or foil for at least 3-4 hours.
- When ready to make, add half the watermelon to the food processor and blend until smooth. Scrape down the sides and add the yogurt, coconut milk, or condensed milk. Add the remaining watermelon and blend until smooth and creamy.
- Eat immediately or freeze for 2-3 hours for a firmer texture. If frozen longer, leave it out for 30 minutes before eating so it can soften up and become creamy.
Ingredients You’ll Need for Two Ingredient Watermelon Ice Cream
This is genuinely one of those recipes where the ingredient list is almost shorter than the instructions. You need watermelon—seedless makes life easier but you can pick out seeds if needed—and your choice of creamy ingredient.
| Ingredient | Amount | Notes |
|---|---|---|
| Watermelon | 3 cups, cubed | Seedless variety works best, cut into 1-inch chunks |
| Lite canned coconut milk | 1/2 cup | Or substitute plain yogurt or sweetened condensed milk |
Choosing Your Watermelon
You want ripe, sweet watermelon for this. When you’re at the store, look for one that feels heavy for its size and has a creamy yellow spot on one side where it sat on the ground. That yellow patch should be buttery colored, not white or green.
If your watermelon isn’t super sweet, the ice cream will taste bland. I learned this the hard way with an early-season melon that looked gorgeous but tasted like crunchy water. The recipe can’t fix flavorless fruit, so taste a piece before you commit to freezing three cups of it.
About the Creamy Component
I usually reach for lite canned coconut milk because it’s what I keep in the pantry anyway. The full-fat version works too but can taste a bit heavy and almost overpower the delicate watermelon flavor. Lite gives you just enough creaminess without taking over.
Plain yogurt—Greek or regular—adds a nice tangy contrast and extra protein. It makes the ice cream taste almost like froyo, which I actually love on really hot days.
Sweetened condensed milk turns this into a richer, sweeter treat that’s closer to traditional ice cream. Use this option when you want something that feels more indulgent or if you’re serving kids who might wrinkle their noses at anything too “healthy” tasting.
Step-by-Step Instructions for Making Watermelon Ice Cream
The process is almost embarrassingly simple. You’re basically just freezing fruit and blending it with something creamy. But there are a few little tricks that make the difference between icy chunks and smooth, scoopable ice cream.
- Freeze the watermelon: Cut your watermelon into roughly 1-inch cubes and spread them in a single layer on a baking sheet lined with parchment paper or foil. Make sure they’re not touching each other or they’ll freeze into one big clump. Pop the whole thing in the freezer for at least 3-4 hours, though overnight works great too.
- Start blending: When you’re ready to make your two ingredient watermelon ice cream, pull out your food processor and add half of the frozen watermelon cubes. Pulse a few times to break them up, then blend continuously until the pieces turn into a fine, snow-like texture. This takes about 30-45 seconds depending on how powerful your food processor is.
- Add the creamy ingredient: Scrape down the sides of the bowl with a spatula, then pour in your coconut milk, yogurt, or sweetened condensed milk. Add the remaining frozen watermelon on top.
- Blend until smooth: Process everything together until it’s completely smooth and creamy, stopping to scrape down the sides once or twice. You’ll see it transform from chunky to silky in about a minute. The mixture should look like soft-serve and have a pale pink color.
- Serve or freeze: At this point, you can eat it immediately as soft-serve style ice cream—which is honestly my favorite way because the texture is perfect. Or transfer it to a freezer-safe container and freeze for 2-3 hours if you want something you can scoop like traditional ice cream. If you freeze it longer than that, let it sit on the counter for about 30 minutes before serving so it softens back up and gets creamy again.
Expert Tips for the Creamiest Results
Make sure your watermelon is frozen completely solid before blending. If it’s only partially frozen, you’ll end up with more of a slushy texture instead of ice cream. I usually freeze mine overnight just to be sure.
A food processor works better than a blender for this recipe. Blenders tend to leave chunks near the top while over-blending the bottom. Food processors give you more even control, and the wider bowl makes it easier to scrape down the sides.
Don’t skip the step of blending half the watermelon first before adding the liquid. If you dump everything in at once, the liquid settles to the bottom and the frozen fruit just spins on top without really blending smoothly.
The ice cream tastes best when it’s freshly made or within the first day of freezing. After that, it can get a bit icy as the watermelon’s natural water content starts to separate and crystallize. It’s still totally edible, just not quite as creamy.
If you want a little extra flavor, add a squeeze of lime juice or a tiny pinch of salt before blending. Both help bring out the watermelon’s sweetness in a really nice way.
Creative Variations to Try
Once you’ve nailed the basic recipe, it’s fun to play around with additions. A handful of fresh mint leaves blended in gives you a super refreshing mint-watermelon combo that tastes like summer in a bowl.
You can also mix in a handful of frozen strawberries or raspberries for a more complex fruit flavor. I’ve done half watermelon and half strawberries, and it’s gorgeous—and tastes like the kind of popsicles you’d pay too much for at a farmers market.
For a tropical twist, use full-fat coconut milk and add a splash of pineapple juice. It turns the whole thing into a piña colada-ish situation that’s ridiculously good.
If you’re feeling fancy, swirl in some chocolate chips or crushed cookies right before serving. They add a nice textural contrast, and honestly, chocolate and watermelon is weirdly delicious together.
You can also turn this into popsicles. Just pour the freshly blended mixture into popsicle molds and freeze until solid. Way easier than trying to scoop rock-hard ice cream later.
Troubleshooting Common Issues
If your ice cream comes out icy instead of creamy, your watermelon might have been too watery to begin with, or you didn’t blend it long enough. Keep processing until it’s completely smooth with no visible chunks. The friction from blending actually helps create that creamy texture.
Too thin and slushy? You probably added too much liquid, or your watermelon wasn’t frozen solid. Next time, use a bit less coconut milk or yogurt—you can always add more, but you can’t take it out once it’s in there.
If it’s too hard to scoop after freezing, just leave it on the counter for 20-30 minutes. Homemade ice cream without stabilizers or emulsifiers always freezes harder than store-bought. That’s actually a good sign—it means there’s nothing weird in there.
Grainy texture usually means the watermelon had too many seeds, or there were white parts of the rind mixed in. Make sure you’re only using the red flesh, and blend thoroughly.
If the flavor is too bland, your watermelon wasn’t sweet enough to start with. Try adding a tablespoon of honey or a splash of watermelon juice to boost the flavor.
How to Store Watermelon Ice Cream
This two-ingredient watermelon ice cream keeps in the freezer for about a week, though the texture is definitely best within the first day or two. Store it in an airtight container—I like those shallow rectangular ones because they make scooping easier.
| Storage Method | Duration | Notes |
|---|---|---|
| Refrigerator | Not recommended | Will melt into juice |
| Freezer (airtight container) | Up to 1 week | Best within 1-2 days; thaw 30 minutes before serving |
| Popsicle molds | Up to 2 weeks | Holds texture better in individual portions |
Press a piece of parchment paper directly on the surface before sealing the container. This helps prevent ice crystals from forming on top. It’s the same trick you’d use for any homemade ice cream.
If you know you’re making this for later in the week, consider portioning it into individual servings right away. Smaller portions thaw faster, and you’re not repeatedly opening and closing one big container, which causes freezer burn.
According to the FDA’s guidelines on safe food handling, homemade frozen desserts should be kept at 0°F or below and consumed within a week for best quality and safety.
Two-Ingredient Watermelon Ice Cream FAQs
What are the two ingredients needed for watermelon ice cream?
The two ingredients are fresh watermelon and heavy cream or coconut cream. You simply need cubed and frozen watermelon pieces and cream to blend together until smooth and creamy. Some recipes use sweetened condensed milk as the second ingredient instead of cream.
Do I need an ice cream maker to make two-ingredient watermelon ice cream?
No, you do not need an ice cream maker. This recipe is designed to be simple and equipment-free. You just need a blender or food processor to blend the frozen watermelon with cream until it reaches a smooth, ice cream-like consistency. You can serve it immediately as soft-serve or freeze it for a firmer texture.
How long does homemade watermelon ice cream last in the freezer?
Homemade watermelon ice cream can be stored in an airtight container in the freezer for up to two weeks. For best texture and flavor, it’s recommended to consume it within the first week. When ready to serve, let it sit at room temperature for a few minutes to soften slightly for easier scooping.
Can I make this watermelon ice cream dairy-free?
Yes, you can easily make this ice cream dairy-free by using coconut cream instead of heavy dairy cream. Full-fat canned coconut cream works perfectly and creates a rich, creamy texture similar to traditional ice cream. This makes it suitable for those who are lactose intolerant or following a vegan diet.
Why does my watermelon ice cream become icy or hard after freezing?
Watermelon has high water content, which can cause the ice cream to become icy when frozen solid. To prevent this, make sure to use enough cream to balance the water content, and consider adding a tablespoon of vodka or corn syrup which helps prevent ice crystals. For best results, serve it as soft-serve immediately after blending, or let it thaw slightly before serving if frozen.
