Step‑by‑Step Instructions for Watermelon Mochi
Step 1: Make Watermelon Juice
Begin by cutting a ripe watermelon into chunks and placing the pieces into a high-powered blender. Blend until smooth, then strain the mixture through a fine mesh sieve into a bowl. You will need about ¾ cup of fresh watermelon juice for the Watermelon Mochi, ensuring it captures that vibrant, sweet flavor.
Step 2: Prepare the Mochi Mixture
In a large mixing bowl, whisk together glutinous rice flour, maple sugar, and tapioca starch until well combined. Create a well in the center of the mixture, then pour in the freshly made watermelon juice and 1 tablespoon of avocado oil. Stir the ingredients together until you achieve a smooth, thick batter that should be slightly sticky.
Step 3: Cook the Mochi
Preheat a non-stick skillet over low to medium heat, adding the remaining tablespoon of avocado oil to coat the surface. Pour the mochi mixture into the skillet, stirring continuously for about 3-4 minutes. Continue cooking until the batter thickens significantly and changes to a slightly darker hue, resembling a thick paste, which indicates it’s ready to be shaped.
Step 4: Shape the Mochi
Remove the cooked mochi mixture from the skillet and let it cool for a minute. Using oiled hands, form the mixture into a ball, then flatten it slightly to create a square shape on a piece of parchment paper. Wrap the mochi in the parchment paper and refrigerate for 1-2 hours until it firms up, making it easier to cut.
Step 5: Dust and Cut
Once chilled, dust the solidified Watermelon Mochi with glutinous rice flour to prevent sticking. Use a sharp knife to cut the chilled square into cubes or strips, ensuring each piece is generously coated in the flour to maintain the soft texture. Serve these delightful treats immediately for a refreshing dessert experience, perfect for summer gatherings.

Make Ahead Options
These Watermelon Mochi are fantastic for meal prep enthusiasts who want to enjoy a refreshing treat without the last-minute hassle! You can prepare the mochi mixture up to 24 hours in advance. Simply follow all steps through shaping the mochi, then wrap it tightly in parchment paper and refrigerate. For optimal quality, remember to dust the flattened dough with glutinous rice flour to prevent sticking. When it’s time to serve, simply pull it from the fridge, dust it again, and cut it into cubes or strips. You’ll have delightful Watermelon Mochi ready to impress your family and friends with minimal effort!

Watermelon Mochi Recipe FAQs
How do I choose a ripe watermelon for making mochi?
Absolutely! When selecting a watermelon, look for a symmetric shape with a firm, even rind. A ripe watermelon should feel heavy for its size and have a yellow field spot where it rested on the ground. Give it a tap; a deep, hollow sound indicates juiciness, perfect for extracting fresh juice for your Watermelon Mochi.
What’s the best way to store leftover Watermelon Mochi?
You can keep any leftover Watermelon Mochi in an airtight container in the refrigerator for up to 5 days. This helps maintain its delightful chewiness. When ready to enjoy, let it sit at room temperature for a few minutes to revive its texture, as it can become slightly firmer while stored.
Can I freeze Watermelon Mochi for later use?
Absolutely! For longer storage, you can freeze your Watermelon Mochi for up to 3 months. Simply wrap each piece tightly in plastic wrap and store them in a freezer-safe bag or container. This prevents freezer burn and preserves the treat’s delightful flavor. When ready to enjoy, let them thaw in the fridge overnight or at room temperature for about 30 minutes.
What if my mochi mixture is too sticky?
If your mochi mixture is too sticky, it could be due to not adding enough tapioca starch or if the watermelon juice was too runny. Simply sprinkle in a little more tapioca starch, mixing thoroughly, until you achieve the desired thick consistency. When cooking, ensure you’re stirring continuously to prevent any sticking to the skillet.
Is Watermelon Mochi safe for those with allergies?
Yes! Watermelon Mochi is a gluten-free and vegan treat, making it suitable for many dietary preferences. However, be cautious with any additional ingredients, such as toppings, as some might contain allergens. Always check labels and choose options that fit your dietary needs, especially if serving to friends or family with allergies.
