Butter Mochi – A Hawaiian Treat with Chewy, Coconutty Bliss
Hawaii is not just known for its beaches, luaus, and breathtaking sunsets — it’s also a hub of unique and unforgettable desserts. Among them, Butter Mochi stands out as a truly special treat. Soft, chewy, and bursting with coconut flavor, butter mochi is a beloved Hawaiian dessert that bridges the gap between traditional Japanese mochi and Western-style cakes.
This article dives into the history of butter mochi, what makes it so irresistible, tips for making it perfectly at home, and why this dessert deserves a spot in your baking repertoire.
The Origin of Butter Mochi
Butter Mochi is a Hawaiian creation that reflects the islands’ multicultural culinary traditions. While Japanese mochi (made from glutinous rice pounded into a chewy dough) is its cultural cousin, butter mochi adapts the idea into a baked dessert. Instead of pounding rice, it uses glutinous rice flour (mochiko) mixed with butter, sugar, eggs, and coconut milk. The result? A dense, chewy, cake-like square that’s rich but not overly sweet.
It’s the perfect potluck dessert in Hawaii, found at family gatherings, bake sales, and even school fundraisers.

Notes
Why Butter Mochi is So Loved
There’s something addictive about butter mochi’s texture. It’s soft, chewy, and just a little bouncy — similar to a rice cake but with more richness. The coconut milk infuses it with tropical flavor, while the butter makes it indulgent and comforting.
Other reasons it’s adored:
- Gluten-Free Friendly: Made with mochiko flour, it naturally avoids wheat.
- Easy to Make: Everything mixes in one bowl and bakes in a single pan.
- Great for Sharing: Perfectly portioned into squares for potlucks or parties.
- Customizable: Add chocolate chips, ube flavoring, or even a dusting of shredded coconut on top.

Ingredients You’ll Need
The beauty of butter mochi lies in its simple ingredient list. Most recipes call for:
- Mochiko flour (sweet rice flour)
- Coconut milk
- Butter
- Eggs
- Sugar
- Baking powder
- Vanilla extract
Some bakers add evaporated milk for extra richness, while others keep it light with just coconut milk.

Tips for the Perfect Butter Mochi
- Use Mochiko Flour Only – Regular rice flour won’t give you the chewy texture you need.
- Grease Your Pan Generously – Butter mochi loves to stick; parchment paper can help.
- Cool Before Cutting – It needs at least 30 minutes to set before slicing into squares.
- Store Properly – Keep at room temperature for a day or refrigerate up to 3 days. Reheat slightly for the best texture.
Step-by-Step Cooking Method
