Making and sharing this dessert feels like creating a piece of edible art that’s rooted in the most comforting and joyful flavors of summer.

Homemade Focus (Unique Preparation & No-Churn Ice Cream)

This recipe for No-Churn Watermelon Ice Cream Slices is a fantastic celebration of creative, homemade dessert-making, showcasing a unique preparation method and a simple, from-scratch no-churn ice cream base.

I love recipes that teach a clever new skill, and the technique of hollowing out the watermelon using an immersion blender is certainly that! You’re not just using watermelon juice; you’re transforming the fruit itself into the serving vessel. This process – pureeing the flesh inside the rind, pouring out the juice, and then scraping the rind clean – is a truly unique homemade endeavor.

Crafting the no-churn ice cream is another key homemade element. Instead of a complicated custard, you’re simply whisking together the reserved fresh watermelon juice with sweetened condensed milk and a pinch of salt. This flavorful base is then gently folded into freshly whipped cream to create an airy, creamy ice cream that freezes beautifully without an ice cream maker.

From ingeniously preparing the watermelon shell to whipping up the simple no-churn base and assembling the final showpiece, every step emphasizes the fun and impressive results of dedicated, creative homemade preparation.

Flavor Goal

The primary flavor goal of these No-Churn Watermelon Ice Cream Slices is a light, refreshing, and authentically sweet watermelon flavor delivered in a rich, smooth, and creamy ice cream texture, all presented in a stunning visual format.

The ice cream itself should be creamy and smooth, thanks to the classic no-churn base of sweetened condensed milk and whipped heavy cream. The flavor should be dominated by the fresh, sweet, and slightly grassy taste of real watermelon juice, with the sweetened condensed milk providing a rich sweetness and the salt enhancing the fruit’s flavor.

The presentation is a key part of the experience. When sliced, the pinkish ice cream inside the green rind should look just like a real slice of watermelon, perhaps with mini chocolate chips folded in to mimic seeds (a common variation not in this specific recipe, but a good tip!).

The overall effect is a delightful and surprising dessert that is light, refreshing, creamy, sweet, and bursting with the pure, authentic taste of summer watermelon.

Ingredient Insights

Let’s explore the simple yet crucial ingredients for this spectacular dessert:

• Mini seedless watermelon (4- to 5-pounds): The star ingredient, acting as both the flavor source and the serving vessel! A small, round, seedless watermelon is easiest to work with.
• Sweetened condensed milk: The magic ingredient for easy no-churn ice cream. Its high sugar content and thick, milky texture help create a smooth, creamy ice cream that resists forming large ice crystals.
• Fine salt: A tiny pinch is essential for balancing the sweetness and enhancing the natural flavor of the watermelon.
• Heavy cream, chilled: Whipped to firm peaks, it incorporates air into the base, making the no-churn ice cream light and creamy rather than just a dense, frozen block. It must be very cold to whip properly.

Incredibly simple ingredients that, combined with the watermelon rind itself, create a true showstopper!

Essential Equipment

This unique recipe requires a few specific tools, especially for preparing the watermelon shell:

• An Immersion Blender (stick blender): As noted, this is special equipment for this recipe. It’s used to puree the watermelon flesh while it’s still inside the rind.
• A Large bowl: To stand the watermelon upright in while working on it, which helps keep it stable.
• Freezer space: Ample, level freezer space is absolutely critical to fit the entire hollowed-out watermelon shell for multiple, lengthy freezing stages.
• Electric mixer (stand mixer or handheld): Essential for whipping the heavy cream to firm peaks.
• Large bowl (for ice cream base) and Whisk.
• A Spoon: For scraping out the remaining watermelon flesh.
• Paper towels: For drying the inside of the watermelon rind.
• Plastic wrap: For covering the ice cream cake during freezing.
• A Long chef’s knife: For slicing the finished frozen watermelon.
• Serving platter.
• Measuring cups and spoons.

An immersion blender and sufficient freezer space are the most important requirements.

List of Ingredients with Measurements

Here’s the complete list of ingredients, with precise measurements:

• One 4- to 5-pound mini seedless watermelon
• One 14-ounce can sweetened condensed milk
• Pinch of fine salt
• 2 cups heavy cream, chilled

These four simple ingredients create a truly spectacular dessert!

Have your watermelon chilled and your heavy cream very cold before you begin.

Step-by-Step Instructions (Building the Watermelon Ice Cream Cake!)

Let’s create this incredible and fun frozen dessert:

1. Prepare the Watermelon Shell:

• Wash and dry the outside of the watermelon.
• Carefully cut a thin slice off the top of the watermelon, just enough to expose the pink flesh inside and create an opening large enough for your immersion blender.
• Stand the watermelon upright (cut-side up) in a large bowl to keep it stable.
• Insert an immersion blender into the cut opening. Begin to puree the watermelon flesh inside the rind, moving the blender around and following the shape of the watermelon’s interior. Be careful not to press too hard or cut through the sides or bottom of the watermelon rind.
• Once the inside is mostly liquefied, pour out the juice into a large measuring cup or bowl. Measure out 1 ½ cups of this fresh watermelon juice and reserve it for the ice cream base. Save any remaining juice for another use (it’s delicious to drink!).
• Using a large spoon, carefully scoop out any remaining red watermelon flesh from inside the rind, so you are left with a smooth, white interior surface.
• Make sure there is no loose juice remaining inside the watermelon shell. Pat the inside dry with a paper towel.
• Place the hollowed-out watermelon rind “bowl” in the freezer while you make the ice cream (at least 30-60 minutes).

2. Make the No-Churn Ice Cream Base:

• In a large bowl, whisk together the 14-ounce can of sweetened condensed milk, the pinch of fine salt, and the reserved 1 ½ cups of fresh watermelon juice until well combined. Set this mixture aside.

3. Whip the Heavy Cream:

• In a separate large bowl (preferably chilled), pour in the 2 cups of cold heavy cream.
• Using an electric mixer on medium-high speed, whip the cream until it holds firm peaks, about 2-3 minutes. Firm peaks hold their shape and the tip of the peak stands up straight when the beaters are lifted.

4. Combine to Make Ice Cream Mixture:

• Gently fold about half of the whipped cream into the condensed milk and watermelon juice mixture using a rubber spatula. This lightens the condensed milk base, making it easier to incorporate without deflating all the air.
• Once that is combined, pour the lightened mixture back into the bowl with the remaining whipped cream.
• Gently fold everything together until just well blended and no streaks remain. Be careful not to overmix and knock out all the air from the whipped cream.

5. Assemble and Freeze:

• Remove the frozen watermelon rind shell from the freezer.
• Pour the prepared watermelon ice cream mixture into the frozen watermelon, filling it all the way to the top.
• Cover the opening tightly with plastic wrap.
• Carefully place the filled watermelon back in the freezer on a level surface. Freeze until completely solid, at least 3 hours, but preferably up to 12 hours or overnight for the firmest set.

6. Thaw and Slice:

• Important: If the watermelon ice cream has been frozen overnight, it will be very hard. Let it thaw in the refrigerator for about 2 hours, or at room temperature for 30-60 minutes, before attempting to slice it.
• Once slightly thawed, place the watermelon cut-side down on a large cutting board.
• Using a long, sharp chef’s knife, carefully halve the watermelon lengthwise. Then, cut each half lengthwise into 3 or 4 wedges, so they look like classic watermelon slices.

7. Serve:

• Serve the No-Churn Watermelon Ice Cream Slices immediately!

The unique presentation is half the fun!

Troubleshooting

This unique dessert has a few potential challenges:

• Problem: I punctured the watermelon rind while blending!
  • Solution: Be very gentle and try to feel the resistance of the rind with the immersion blender. If a small puncture occurs near the top, it might still be usable. If it’s a large hole near the bottom, unfortunately, you’ll need to transfer the ice cream mixture to a standard loaf pan or other freezer-safe container to freeze.
• Problem: My ice cream is icy, not creamy.
  • Solution: This can happen with no-churn ice cream if it’s not folded gently or if the ratios are off. Ensure you whipped the cream to firm peaks. Gently folding is key to keeping the air incorporated, which prevents iciness. Using full-fat sweetened condensed milk and heavy cream is also crucial.
• Problem: The frozen watermelon is impossible to slice.
  • Solution: It absolutely needs time to thaw slightly before slicing, as the instructions note (2 hours in the fridge or about 30-60 mins at room temp). Do not skip this step! Use a very large, sharp chef’s knife.
• Problem: My immersion blender is struggling.
  • Solution: A powerful immersion blender helps. You can also start by scooping out some of the watermelon flesh with a spoon to create more room for the blender head to work, then puree the rest.

Patience with thawing before slicing is key!

Tips and Variations

Let’s get creative with this incredible watermelon dessert:

• Tip: Choose a mini seedless watermelon that has a flat bottom so it can stand upright stably in the bowl while you work and in the freezer.
• Variation: For a “seeded” watermelon look, gently fold about ½ cup of mini vegan chocolate chips into the ice cream mixture after it’s been folded together, just before pouring it into the watermelon shell.
• Tip: For the best flavor, use a sweet, ripe watermelon. Taste the juice before making the ice cream base; if it’s not very sweet, you could consider adding a tablespoon of light corn syrup or agave to the condensed milk mixture to help with texture and sweetness.
• Variation: Add other flavorings to the ice cream base, such as 2-3 tablespoons of fresh lime juice for a watermelon-limeade flavor, or some finely chopped fresh mint.
• Tip: When unmolding and slicing, ensure you have a large, sturdy cutting board and a very sharp, long knife. This makes a big difference.
• Variation: If the watermelon shell method seems too daunting, you can simply pour the prepared watermelon ice cream mixture into a standard 9×5 inch loaf pan lined with plastic wrap and freeze it that way. You’ll still get delicious watermelon ice cream!
• Variation: Swirl in a layer of raspberry or strawberry sorbet (from previous user recipes) for a colorful, multi-flavored version.

The presentation is the star, but the ice cream is delicious in any container!

Recipe Summary and Q&A

Let’s conclude with a summary and common questions:

Recipe Summary:

No-Churn Watermelon Ice Cream Slices are made by first hollowing out a mini seedless watermelon using an immersion blender to puree the flesh and create a natural serving bowl from the rind. A no-churn ice cream base is made by combining reserved fresh watermelon juice with sweetened condensed milk and salt, then folding this into freshly whipped heavy cream. This mixture is poured into the frozen watermelon shell, frozen solid overnight, and then thawed slightly before being cut into wedges that resemble real watermelon slices.

Q&A:

Q: Do I have to use an immersion blender? A: The immersion blender is the specified tool for the unique technique of pureeing the fruit inside the rind. If you don’t have one, you could try scooping out all the watermelon flesh with a spoon, pureeing it in a regular blender, and then pouring the ice cream mixture back into the scraped-out, dried rind.

Q&A: Can I make this ahead of time? A: Yes, this dessert must be made ahead to allow for the significant freezing time required. You can make it completely up to a week in advance and keep it well-wrapped in the freezer.

Q&A: How do I store leftovers? A: Carefully re-wrap any leftover portion (or individual slices) tightly in plastic wrap and then foil to prevent freezer burn. Store in the freezer for up to 1-2 weeks for best quality.

Q&A: My ice cream mixture seems very liquidy. Will it really freeze into ice cream? A: Yes! The no-churn method relies on the specific properties of sweetened condensed milk and the air incorporated from the whipped cream. It will seem very liquidy at first, but it will freeze into a surprisingly creamy and scoopable (once slightly thawed) ice cream.

Q&A: Can I add alcohol to this? A: Adding alcohol will make the ice cream much softer and may prevent it from freezing solid enough to slice neatly. If you were to try, use a very small amount (e.g., 1-2 tablespoons of a light rum or vodka) and be prepared for a softer final product.
