This chewy, buttery, slightly sweet dessert is a cross between cake and mochi, and it’s bound to win your heart with its irresistible texture and flavor.
In this article, we’ll dive deep into the history of butter mochi, its cultural significance in Hawaii, step-by-step instructions for making it at home, and tips for customizing it to your taste.

What is Butter Mochi?
Butter Mochi is a baked dessert made primarily from glutinous rice flour (mochiko), sugar, eggs, butter, and coconut milk. Unlike Japanese mochi, which is chewy and stretchy from pounding steamed rice, Hawaiian butter mochi is baked like a cake yet retains that chewy, dense texture mochi is famous for.
The addition of butter and coconut milk is what makes this dessert distinctly Hawaiian, reflecting the islands’ rich mix of culinary influences from Japan, the Philippines, Portugal, and beyond.
A Bite of Hawaiian History
Butter mochi’s origins trace back to Japanese immigrants who brought mochiko (sweet rice flour) to Hawaii. Over time, locals began experimenting, adding ingredients like butter and coconut milk that were readily available on the islands. The result was a uniquely Hawaiian fusion dessert: rich, chewy, and utterly addictive.
Today, butter mochi is a staple at potlucks, school bake sales, family gatherings, and local bakeries. It’s a dish that represents community, culture, and comfort food in its truest form.
Ingredients You’ll Need
One of the best parts about butter mochi is its simplicity. With just a few pantry staples and Hawaiian-inspired touches, you can whip it up in no time.
- 1 (16 oz) box mochiko flour (sweet rice flour)
- 2 cups sugar
- 2 teaspoons baking powder
- ½ teaspoon salt
- 4 large eggs
- 1 stick (½ cup) unsalted butter, melted
- 1 (13.5 oz) can coconut milk
- 1 (12 oz) can evaporated milk (or whole milk)
- 2 teaspoons vanilla extract
Step-by-Step Instructions
- Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper.
- Mix the dry ingredients. In a large mixing bowl, whisk together the mochiko flour, sugar, baking powder, and salt until well combined.
- Combine the wet ingredients. In another bowl, whisk together the eggs, melted butter, coconut milk, evaporated milk, and vanilla extract until smooth.
- Bring it all together. Slowly pour the wet mixture into the dry mixture, stirring until a smooth batter forms. The batter will be slightly runny.
- Bake. Pour the batter into the prepared pan and bake for 55–65 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
- Cool and cut. Allow the butter mochi to cool completely in the pan before cutting it into squares. Serve at room temperature.

Notes
Tips for the Perfect Butter Mochi
- Don’t overbake. The key to chewy mochi is not letting it dry out. Remove it from the oven as soon as it’s set and golden.
- Grease well. Butter mochi has a tendency to stick. Use parchment paper or grease generously for easy removal.
- Texture preference. For a denser, chewier bite, use more coconut milk. For a lighter cake-like texture, use a bit more regular milk.

- Chocolate Butter Mochi: Add ½ cup cocoa powder to the batter for a chocolaty twist.
