Chewy Japanese mochi meets rich chocolate truffle filling in this amazing fusion dessert. The mix of textures and tastes creates a treat that'll wow everyone who tries it.
I've tried tons of different ways to make this, and this method gives you the best mix of chewy mochi and creamy chocolate filling. You won't forget how good each bite tastes.
Key Ingredients
- Shiratamako or Mochiko (sweet rice flour): This gives you that chewy bounce we all love. Go with Shiratamako for a smoother feel
- Good cocoa powder: Try Dutch-processed for a much darker chocolate kick
- Semi-sweet chocolate bars: Actual bars work better than chips since they melt into a smoother filling
- Heavy cream: You need the fat in this to make your center super truffle-like
- Cornstarch: Keeps everything from turning into a sticky mess and helps the texture
How To Make It
- Get Your Filling Ready:
- Cut up chocolate into tiny bits so it melts evenly. Warm the heavy cream till you see tiny bubbles at the edges, but don't let it boil. Pour it over the chocolate and wait 5 minutes before you stir it all smooth. Put it in the fridge for about 2 hours until it's firm enough to scoop.
- Mix Up Your Mochi:
- Mix the sweet rice flour, cocoa, and sugar through a strainer to get the lumps out. Slowly add warm milk while you stir until you've got a smooth mix. Cover it with plastic wrap but poke some little holes so steam can get out.
- Cook Your Dough:
- Steam the mix for 20 minutes, giving it a stir halfway. You'll know it's done when it looks shiny and a bit see-through. Touch it to check. It should feel sticky but not raw.
- Put It All Together:
- Sprinkle lots of cornstarch on your counter. Split the mochi into even chunks. Flatten each piece, drop some ganache in the middle, and seal up the edges carefully.
- Finish It Off:
- Roll your finished mochi balls in cocoa powder. Let them sit for 10 minutes before you eat them. If you want, put some fresh berries around them on the plate.

Getting chocolate mochi just right means paying attention to all the little things, from how warm your ingredients are to how you shape each piece. Every step matters for the best taste and feel.
Fixing Common Problems
Easy fixes when things go wrong:
- Too sticky to work with: Change how much flour and liquid you use based on how humid your kitchen is
- Filling melts during shaping: Make sure your ganache is cold enough and work fast with cool hands
Seasonal Twists

Switch things up throughout the year:
- Summer: Add a bit of mint to the chocolate filling to make it more refreshing
- Autumn: Mix in some cinnamon and nutmeg for a warm fall flavor
- Holiday: Try white chocolate inside with some crushed candy canes on top
Keeping It Fresh
Make sure they stay tasty:
- Wrap each mochi separately in plastic before putting in the fridge so they don't dry out
- Make your filling up to two days before to save time on cooking day
- Wrap them tight and freeze for up to a month. Just let them warm up before eating
Fun Changes To Try

Take your mochi to the next level:
- Fill with white chocolate mixed with green tea powder for cool color contrast
- Mix dried raspberry bits into your cocoa coating for a tangy kick
- Put some black sesame paste in your chocolate filling for a nutty flavor
Great Combos
Serve your chocolate mochi with:
- A cup of roasted green tea that brings out the chocolate taste
- A tiny scoop of vanilla ice cream for an awesome hot-cold mix
Chocolate mochi isn't just tasty. It brings together different food traditions in one amazing bite. The mix of chewy outer layer and velvety chocolate center makes it something really special that you'll want to make again and again.
Frequently Asked Questions
- → Can I make these in advance?

- → Why is the dough so sticky?
- Sticky dough is normal! Handle it easily by using oil or cornstarch on your hands.
- → Can these go in the freezer?
- Freezing isn’t great since it messes up the mochi texture!
- → What chocolate should I use?
- Semi-sweet is your best bet, but dark chocolate works if you like bold flavors.
- → My ganache didn’t thicken—why?
- It might need more chilling time or better chocolate-to-cream proportions—1-2 hours should be just right.
