Ingredients You’ll Need
Getting the ingredients right is key to nailing both the texture and vibrant flavor in this Watermelon Mochi Recipe. Each component is simple but essential, contributing to the perfect chewy consistency and refreshing taste.
- 1 cup glutinous rice flour (mochiko): This is the foundation of your mochi, giving it that iconic chewy texture you’ll adore.
- 1/4 cup granulated sugar: Sweetness that balances the tart watermelon perfectly without overpowering it.
- 2/3 cup watermelon juice: Freshly blended and strained, this juice brings in natural flavor and gorgeous pink color.
- 1/4 teaspoon vanilla extract (optional): Adds a subtle depth to the flavor profile, complementing the fruitiness.
- 1–2 drops pink or red food coloring (optional): For a vibrant hue that makes your watermelon mochi visually pop.
- Cornstarch or potato starch (for dusting): Keeps the sticky mochi easy to handle and prevents clumping.
- 1/3 cup mini chocolate chips (optional): These mimic watermelon seeds and add little bursts of chocolatey goodness.
How to Make Watermelon Mochi Recipe
Step 1: Mix the Mochi Dough
First, take a microwave-safe bowl and whisk together the glutinous rice flour, sugar, and freshly strained watermelon juice until everything is perfectly smooth. If you want, stir in a little vanilla extract for extra flavor and a couple of drops of pink or red food coloring to bring out that inviting watermelon shade.
Step 2: Microwave the Mixture
Cover the bowl loosely with plastic wrap or a microwave-safe plate to keep moisture in, then microwave on high for 2 minutes. Take it out and give it a good stir — you’ll start noticing the mixture thickening up beautifully. Pop it back in for 1 to 2 more minutes until it turns thick, sticky, and just a little bit translucent.
Step 3: Prepare the Mochi for Shaping
Dust a clean surface generously with cornstarch or potato starch. Carefully transfer your hot mochi dough onto this surface — be mindful, it will still be warm but manageable after a minute or two of cooling. Dust your hands with starch to prevent sticking and gently flatten the dough out.
Step 4: Add the Chocolate “Seeds”
Sprinkle mini chocolate chips across the top of the flattened mochi dough. Using gentle kneading or pressing motions, incorporate them slightly so they stick to the surface but don’t get lost within the dough. This adds not only a fun visual pop but also a subtle surprise of chocolate flavor.
Step 5: Shape and Finish the Mochi
Cut or shape the mochi into small squares or roll it into bite-sized balls — whatever you prefer! To keep your mochi pieces from sticking to each other or your fingers, coat them lightly in starch. Serve immediately for that soft, fresh chew, or chill them for 15 to 30 minutes if you like a firmer texture.
How to Serve Watermelon Mochi Recipe
Garnishes
A sprinkle of toasted coconut flakes or a few extra chocolate chips on top can add texture and a bit of flair. For a refreshing twist, a small mint leaf on each piece delivers a bright contrast that wakes up your taste buds.
Side Dishes
Watermelon mochi pairs wonderfully with light, fresh accompaniments like a fruit salad or a scoop of sorbet. This keeps your dessert plate feeling balanced and cool, especially on a warm day when you want something sweet but not heavy.
Creative Ways to Present
Try wrapping the mochi around a small scoop of vanilla or fruit sorbet and serving it immediately for a fun frozen treat. You can also arrange the mochi balls on skewers for an adorable party snack or present them in cute cupcake liners to make each piece feel special.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, make sure to store your watermelon mochi in an airtight container at room temperature for the best texture. Refrigeration tends to dry them out or makes them hard, so keep it cool but not chilled unless you prefer a firmer bite.
Freezing
You can freeze watermelon mochi, but because of its delicate soft texture, it’s best to consume within a week. Wrap each piece individually in plastic wrap and place them in a freezer-safe container. Thaw at room temperature before serving, although they may be a bit chewier afterward.
Reheating
To bring your mochi back to life, lightly steam the pieces or microwave them for 10 to 15 seconds to soften again. Be careful not to overheat, as this can make them too sticky or change their texture.
FAQs
Can I use watermelon chunks instead of juice for this Watermelon Mochi Recipe?
The mochi requires a smooth, liquid form of watermelon flavor, so blending and straining the juice is best for an even texture. Using chunks wouldn’t mix properly into the dough.
Is this recipe vegan and gluten-free?
Absolutely! The Watermelon Mochi Recipe uses glutinous rice flour, which is gluten-free, and if you skip the chocolate chips or use dairy-free chocolate, it remains vegan-friendly.
What’s the best way to make the mochi less sticky?
Using plenty of cornstarch or potato starch for dusting is key to preventing sticking. Also, dust your hands before handling the dough and coat the finished mochi pieces well.
Can I make watermelon mochi without a microwave?
Yes, you can steam the mochi dough for about 15 minutes instead of microwaving. Just remember to stir the mixture occasionally for even cooking.
How long does watermelon mochi last?
For the best flavor and texture, enjoy your watermelon mochi the same day you make it. If stored properly, it can last up to 1 day at room temperature or up to a week frozen.

- Combine Ingredients: In a microwave-safe bowl, whisk together glutinous rice flour, granulated sugar, and freshly strained watermelon juice until the mixture is smooth and free of lumps. Add vanilla extract and food coloring if desired for enhanced flavor and a vibrant appearance.
- Microwave the Mochi Dough: Cover the bowl loosely with plastic wrap or a microwave-safe plate to prevent splattering.
