The Best 3-Ingredient Watermelon Ice Cream (So Easy!)
Why You’ll Love This Recipe
I first tried making watermelon ice cream on a scorching July afternoon when my fridge was practically empty. The kids were begging for something cold and sweet, but I refused to run to the store. I grabbed a half-eaten watermelon, some heavy cream I had leftover from a baking project, and a can of sweetened condensed milk that had been sitting in my pantry for months. I honestly thought it would be a disaster.
To my absolute shock, it turned out incredibly creamy and perfectly sweet. The texture was nothing like the icy, watery mess I expected. The natural watermelon flavor shone through beautifully. It was so good that my family ate the entire batch in one sitting. Now, this 3-Ingredient Watermelon Ice Cream has become our go-to summer tradition. It solves the problem of what to do with leftover watermelon and gives you a homemade frozen dessert that tastes way better than anything from a box.
Ingredients
- 4 cups cubed seedless watermelon, frozen solid
- 1 cup heavy cream, cold
- 1/2 cup sweetened condensed milk
Step-by-Step Directions
- Start by freezing your watermelon cubes. Spread them out on a parchment-lined baking sheet so they don’t clump together. Let them sit in the freezer for at least 4 hours, or overnight. You want them rock hard.
- When you are ready to make the ice cream, pull your frozen watermelon cubes out of the freezer. Let them sit on the counter for exactly 5 minutes. This softens them just enough so your blender doesn’t struggle.
- Pour the cold heavy cream into your blender or food processor first. Then add the frozen watermelon cubes on top. Finally, drizzle in the sweetened condensed milk.
- Pulse the blender a few times to break up the big chunks. Then blend on high for about 30 seconds. You will hear the sound change from a loud crunching noise to a smooth whir. Stop the blender and scrape down the sides with a spatula.
- Blend again for another 15 to 20 seconds. The mixture should look like a thick, creamy milkshake. It will be soft and scoopable right away, like soft serve.
- For firmer ice cream, pour the mixture into a freezer-safe container. Smooth the top with a spatula, cover it with a lid or plastic wrap, and freeze for at least 2 hours. It will be scoopable after this time.
Pro Tips for Success
Freezing the watermelon on a flat tray is the most important step. If you just toss chunks into a bag, they freeze into one giant block that your blender cannot handle. You want individual cubes.
Do not over-blend the mixture. Once it turns smooth and creamy, stop. If you keep blending, the heat from the motor will melt the watermelon and your ice cream will turn watery.
Always use cold heavy cream straight from the fridge. Warm cream will not whip up properly and your final texture will be thin and icy. Heavy cream with at least 36% milk fat gives the best results.
Servings and Timing
This recipe makes about 4 cups of 3-Ingredient Watermelon Ice Cream, which serves 4 to 6 people. The active prep time is only 5 minutes, but you need to freeze the watermelon for at least 4 hours ahead of time. If you want firm ice cream, add another 2 hours of freezer time after blending.
Variations and Substitutions
If you want a dairy-free version, swap the heavy cream for full-fat coconut cream and use a dairy-free sweetened condensed milk alternative. The coconut flavor pairs beautifully with watermelon.
For a tangy twist, add 2 tablespoons of fresh lime juice and a pinch of salt to the blender. This gives the ice cream a margarita-like vibe that is incredibly refreshing.
You can also fold in some mini chocolate chips or crushed mint leaves after blending for extra texture and flavor. Just stir them in gently before freezing.
What to Serve With This
This light and fruity ice cream is perfect on its own, but it also pairs wonderfully with other summer treats. Try serving it alongside some [LINK: 5 Ingredient Raspberry Shortbread Bars]Raspberry Shortbread Bars[/LINK] for a sweet and buttery contrast. For a boozy adult pairing, whip up a batch of [LINK: Frozen Watermelon Margarita Slush with TajΓn Rim]Watermelon Margarita Slush[/LINK] for the ultimate summer party spread.
Storage and Reheating
Store any leftover 3-Ingredient Watermelon Ice Cream in a tightly sealed freezer container. Press a piece of parchment paper directly onto the surface of the ice cream before sealing the lid. This prevents ice crystals from forming and keeps the texture creamy for up to two weeks.
When you are ready to eat, let the container sit on the counter for 5 to 10 minutes. This softens the ice cream enough to scoop easily without breaking your spoon. Do not microwave it to soften, as that will melt the edges and ruin the texture.
FAQs
Q: Can I use a regular blender or do I need a high-speed one?
A regular blender works fine as long as you let the frozen watermelon cubes sit out for 5 minutes first. If your blender struggles, add one tablespoon of cold milk or water to help things move. Just do not add too much liquid or your ice cream will be icy.
Q: What happens if my watermelon is not sweet enough?
If your watermelon tastes bland, your ice cream will taste bland too. Taste a cube before freezing. If it needs more sweetness, add an extra tablespoon of sweetened condensed milk to the blender. You can also drizzle in a little honey or agave syrup.
Q: Can I use frozen watermelon from the grocery store?
I do not recommend it. Pre-frozen watermelon chunks are usually mushy and watery when thawed. They will give you a slushy texture instead of creamy ice cream. Always freeze fresh watermelon yourself for the best results.
Q: Why did my ice cream turn out icy instead of creamy?
This usually happens when you add too much liquid or over-blend the mixture. The heavy cream and sweetened condensed milk are what give the ice cream its creamy texture. If you add extra milk or water, you dilute that creaminess. Stick to the exact ingredient amounts.
Q: Can I make this without a blender at all?
Technically yes, but it takes a lot of elbow grease. You would need to grate the frozen watermelon on a box grater, then whisk the grated watermelon into the cream and condensed milk. The texture will be chunkier and more like a granita than ice cream.
