It is the end of July. You bought a massive 15-pound watermelon for a weekend BBQ, your family ate half of it, and now the rest is sitting in a giant Tupperware taking up half your refrigerator. Sound familiar?
Before that leftover fruit gets soft and mushy, it is time to turn it into the ultimate summer dessert: 2-Ingredient Watermelon Ice Cream.
If you are endlessly searching for fresh watermelon recipes to beat the heat, this is your new holy grail. You don’t need an expensive ice cream maker, you don’t need to cook a custard base, and you don’t even need heavy whipping cream.
With just frozen watermelon cubes, a splash of sweetened condensed milk, and a food processor, you can create a perfectly creamy, soft-serve watermelon ice cream in exactly 3 minutes. It is the easiest, most refreshing summer hack you will ever try!

- Only 2 Ingredients: It truly does not get any easier than this.
- No Ice Cream Maker Required: If you have a blender or a food processor, you are ready to go.
- The “Creamy” Secret: Watermelon is 92% water, which normally freezes into hard ice. Sweetened condensed milk prevents those ice crystals from forming!

- Zero Waste: The absolute best way to use up a giant watermelon before it goes bad.
🛒 Ingredients & The “Dairy-Free” Guide
- 4 cups Seedless Watermelon: (Cut into 1-inch cubes and completely frozen. See my flash-freezing hack below!).
- ½ cup Sweetened Condensed Milk: (This is the magical binder! It adds the perfect amount of milky creaminess and sugary sweetness, neutralizing the icy texture of the frozen fruit).
Want to make it Vegan / Dairy-Free? 🌱
Simply swap the traditional condensed milk for Sweetened Condensed Coconut Milk or Cream of Coconut (like Coco López). It gives the ice cream an incredibly delicious tropical Piña Colada vibe!
🍳 Step-by-Step Masterclass Instructions
Step 1: The “Parchment Paper” Freeze (Crucial!) ❄️
If you just throw your chopped watermelon into a Ziploc bag, it will freeze into a giant, solid red brick that will break your blender!
Instead, line a large baking sheet with parchment paper. Arrange your 4 cups of cubed watermelon in a single layer so the pieces are not touching. Place the tray flat in the freezer for 3 to 4 hours until the cubes are rock-hard.
(Once frozen, you can transfer them to a bag for long-term storage!)
Step 2: The 3-Minute Blend 🌪️
Place your frozen watermelon cubes directly into a high-powered food processor or a heavy-duty blender (like a Vitamix or Ninja). Pulse a few times to break the large cubes down into smaller icy chunks.
Step 3: Pour the Magic Binder
While the machine is running on low, slowly pour the ½ cup of sweetened condensed milk through the top opening.
Step 4: Scrape and Whip
Turn the speed up to high. The mixture will look crumbly and icy at first—don’t panic! Stop the machine once or twice to scrape down the sides with a rubber spatula. After about 2 to 3 minutes of blending, the mixture will magically transform into a smooth, thick, creamy, bright pink soft-serve ice cream!
Step 5: Serve or Freeze 🍦
- For Soft Serve: Scoop it directly from the blender into bowls and eat it immediately! It will have the texture of a creamy, thick smoothie bowl or Dole Whip.
- For Scoopable Ice Cream: Transfer the mixture into a metal loaf pan. Press a piece of plastic wrap directly against the surface of the ice cream and freeze for 2 to 3 hours. It will firm up beautifully so you can serve it in crispy waffle cones!
🍋 2 Flavor-Boosting Variations
While this is amazing with just two ingredients, you can easily elevate it!
- Watermelon Limeade Ice Cream: Add 1 tablespoon of fresh lime juice and 1 teaspoon of lime zest to the blender. The tart citrus makes the watermelon flavor pop!
- Strawberry Watermelon: Swap 1 cup of the frozen watermelon for 1 cup of frozen strawberries for a mixed-berry delight.
🔒 Storage Instructions
- Freezer: Store any leftover ice cream in an airtight, freezer-safe container for up to 1 month.
- Serving Tip: Because homemade ice cream does not contain commercial chemical stabilizers, it will freeze quite hard overnight. Simply let it sit on the kitchen counter for 10 minutes before scooping!
