Strawberry Matcha Mochi Lava Bites

Yields: 8-10 pieces
Prep time: 40 minutes
Cook time: 5 minutes (plus cooling)

These Strawberry Matcha Mochi Lava Bites are the ultimate fusion dessert. We’ve taken the traditional Japanese sweet and filled it with a bright, tangy strawberry-white chocolate ganache that melts into a luscious “lava” when you bite into it. The chewy, slightly bitter matcha-infused mochi shell perfectly balances the sweet, creamy filling. Each bite is a delightful interplay of textures and flavors, making it a stunning treat for any occasion.

Ingredients

For the Strawberry Lava Filling:

1 cup (170g) high-quality white chocolate chips or chopped white chocolate bar
¼ cup (60ml) heavy whipping cream
¼ cup (60g) fresh strawberry puree (made by blending 4-5 strawberries until smooth)
⅛ teaspoon salt
1 drop pink food coloring (optional, for color enhancement)

For the Matcha Mochi Dough:

1 cup (150g) sweet rice flour (mochiko flour)
¼ cup (50g) granulated sugar
1 tablespoon culinary-grade matcha powder, sifted
¾ cup (180ml) water
1 teaspoon vanilla extract

For Dusting and Assembly:

¼ cup (30g) cornstarch or potato starch (katakuriko), for dusting
½ cup (60g) white chocolate chips, for drizzling
Fresh strawberries, halved, for serving

Instructions

Step 1: Prepare the Strawberry Lava Filling

In a small saucepan over low heat, combine the heavy cream and strawberry puree. Heat until it just begins to simmer (do not let it come to a full boil).
Remove from heat and add the white chocolate chips and salt. Let sit for 2 minutes.
Whisk gently until all the chocolate is completely melted and the mixture is smooth and glossy. Whisk in the food coloring if using.
Pour the mixture into a shallow container and refrigerate for 1-2 hours, or until it is firm enough to handle but still soft in the center.
Once firm, scoop out small, teaspoon-sized portions of the ganache and roll them into small balls. Place the balls on a parchment-lined plate and return them to the refrigerator to keep them firm until you are ready to assemble the mochi.

Step 2: Make the Matcha Mochi Dough

In a microwave-safe bowl, whisk together the sweet rice flour, sugar, and sifted matcha powder until well combined.
Add the water and vanilla extract. Whisk until you have a smooth, uniform batter.
Cover the bowl loosely with plastic wrap and microwave on high for 1 minute.
Remove the plastic wrap (be careful of hot steam) and stir the mixture vigorously with a heat-proof spatula. It will be thick and sticky.
Recover and microwave for another 30 seconds.
Stir again. The mochi should be translucent, very sticky, and elastic. If there are still opaque white spots, microwave for an additional 15 seconds.

Step 3: Assemble the Mochi Bites

Generously dust your work surface and your hands with cornstarch. This is crucial to prevent sticking.
Turn the hot mochi dough out onto the cornstarch-dusted surface. Dust the top of the dough lightly with more cornstarch.
Roll the dough into a log shape and divide it into 8-10 equal pieces.
Working with one piece at a time, flatten the dough into a thin circle, about 3 inches in diameter, ensuring the edges are slightly thinner than the center. (Keep the other pieces covered with plastic wrap to prevent them from drying out).
Place one chilled strawberry ganache ball in the center of the mochi circle.
Gather the edges of the mochi dough up and over the filling, pinching them tightly together to seal completely. Dust off any excess cornstarch.
Place the finished mochi ball on a serving plate, seam side down. Repeat with the remaining mochi dough and filling.

Step 4: Decorate and Chill

Place the remaining ½ cup of white chocolate chips in a small microwave-safe bowl. Microwave in 20-second intervals, stirring in between, until the chocolate is melted and smooth.
Transfer the melted white chocolate to a small piping bag or a Ziploc bag with the tip snipped off.
Drizzle the white chocolate over the top of each mochi bite.
Refrigerate the assembled mochi bites for at least 20 minutes to allow the ganache to firm up slightly and the mochi to set.

Step 5: Serve

For the best “lava” effect, let the mochi bites sit at room temperature for 15-20 minutes before serving.
Serve each mochi bite with a fresh strawberry half on the side. Cut into one immediately to reveal the molten strawberry center.

Tips

Mochi Handling: Mochi dough is extremely sticky. Always keep your hands and work surface generously dusted with cornstarch. If the dough tears during assembly, you can pinch it together to repair it.
Preventing Dry Dough: Keep the divided mochi pieces covered with plastic wrap while you assemble each bite to prevent them from drying out and cracking.
Culinary Matcha: Use high-quality culinary or ceremonial grade matcha for the best vibrant color and flavor. A lower-quality matcha can taste grassy or bitter.
Ganache Consistency: The ganache should be firm enough to roll but soft enough to melt. If it’s too soft, refrigerate it longer. If it’s too hard, let it sit at room temperature for a few minutes.

Storage and Reheating

Storage: These mochi bites are best eaten fresh on the day they are made. However, they can be stored in an airtight container in the refrigerator for up to 2 days. The mochi will become chewier over time.
Reheating: To restore the soft texture of the mochi, you can microwave a chilled mochi bite for 10-15 seconds on low power. Be careful not to overheat it, or the ganache will explode! The ganache inside will become very hot.

Serving Suggestions

Serve these mochi bites on a platter dusted with matcha powder for a beautiful presentation. They pair wonderfully with a warm cup of hojicha or sencha tea. For a more decadent dessert, serve alongside a scoop of vanilla bean ice cream.
