What Is Butter Mochi?
Butter mochi is Hawaii’s answer to comfort food — part cake, part mochi, and 100% joy. At its core, it’s made from glutinous rice flour, also called mochiko, which gives it that signature chew. The rest is a luscious blend of coconut milk, butter, sugar, eggs, and a pinch of salt for balance.
Unlike traditional Japanese mochi that’s steamed, pounded, and shaped, butter mochi is baked. This Western-style twist transforms the sticky rice batter into a golden slab that’s both crisp-edged and chewy — like a brownie, but made of rice.
The first bite usually surprises people: it’s stretchy, slightly bouncy, and rich with buttery, coconut aroma. The texture sits somewhere between custard and cake — and that’s what makes it so irresistible.
Why This Dessert Matters (and Why It’s Trending)
Butter mochi tells a story of cultures colliding in the sweetest way. When Japanese immigrants came to Hawaii in the early 20th century, they brought mochi-making traditions. Locals added butter, eggs, and coconut milk — pantry staples from Western-style baking — and a new hybrid dessert was born.
Today, butter mochi is having its moment again. Why? Because it fits perfectly into the modern dessert landscape:
- It’s naturally gluten-free.
- It’s easy to make — no kneading or shaping needed.
- It keeps beautifully moist for days.
- And, let’s be honest — that chewy texture is just addictive.
Social media has also played a big role. Videos of its gooey center and glossy tops are pure ASMR bliss. From home bakers in Tokyo to pastry chefs in LA, everyone’s giving butter mochi their own spin — think matcha, ube, and pumpkin spice.
Speaking of color and flavor — my Ube Butter Mochi is a dreamy purple twist that’s soft, nutty, and picture-perfect.
How To Make It: The Basics of Method & Technique
Making butter mochi is one of those recipes that feels like magic — minimal effort, maximum reward.
The Ingredients
Here’s what you’ll need for a classic version:

The Equipment
You don’t need much — just a mixing bowl, whisk, and a baking pan (8×8-inch or 9×13-inch depending on how thick you want your squares).
