Butter Mochi Recipe Hawaii: Chewy Coconut Sweetness with Island Flavor

This Hawaiian-inspired treat delivers a unique texture that’s both chewy and tender, with rich coconut and butter flavors in every bite.

I’ve perfected this method to ensure a golden crust outside while keeping the inside soft and moist, using simple ingredients that come together beautifully.

The Mochiko flour is non-negotiable—it’s what gives this its signature chewy texture. You’ll find it in the Asian aisle of Walmart or H-Mart, or order online if your local store doesn’t stock it. Use the full-fat coconut milk (like Thai Kitchen or Native Forest); the lite version just won’t cut it. Butter should be melted but not hot when you mix it in—cool it for 5 minutes first (worth the extra minute).

No Mochiko? Don’t bother—regular rice flour won’t work here. Swap the shredded coconut for macadamia nuts if you want a crunchier texture. The almond extract is optional, but it really boosts the island flavor. If you’re out of vanilla, coconut extract at half the amount works in a pinch, but the vanilla adds depth. Eggs must be room temp—cold ones can make the batter clumpy.

Store leftovers in an airtight container at room temp for 3 days, or freeze for up to 3 months. These actually taste better the next day once the flavors meld. Reheat briefly in the microwave to soften—just 10-15 seconds (don’t skip this part).

Step-by-Step Instructions for Butter Mochi

This traditional Hawaiian treat comes together with simple mixing and a single bake.

Step 1: Prepare the Wet Ingredients

In a large mixing bowl, whisk together the 0.5 cup Unsalted Butter (melted and cooled slightly) with the 1.5 cups Granulated Sugar until smooth and fully combined. The mixture should have a slightly grainy texture from the sugar, which is normal at this stage.

Add the 4 whole Large Eggs one at a time, whisking well after each addition until the mixture is pale and slightly thickened. Then stir in the 1 can Coconut Milk, 2 tsp Vanilla Extract, and 0.25 tsp Almond Extract. The coconut milk adds richness, while the extracts enhance the tropical flavor profile.

Step 2: Combine Dry Ingredients

In a separate bowl, sift together the 1 lb Mochiko Sweet Rice Flour, 1 tsp Baking Powder, and 0.25 tsp Salt. Sifting the flour ensures a smooth batter without lumps, which is crucial for the signature chewy texture of this dish.

Gradually add the dry ingredients to the wet mixture, stirring just until combined. Avoid overmixing, as this can make the final product dense. The batter will be thick but pourable, similar to pancake batter.

Step 3: Fold in Shredded Coconut

Gently fold in the 1 cup Shredded Coconut using a spatula, ensuring it is evenly distributed throughout the batter. The coconut adds texture and reinforces the island-inspired flavor. If using sweetened shredded coconut, you may notice a slightly sweeter taste in the finished product.

Let the batter rest for 5 minutes to allow the flour to hydrate fully. During this time, preheat your oven to 350°F to ensure it reaches the proper temperature before baking.

Step 4: Bake Until Golden and Set

Pour the batter into a greased 9×13-inch baking pan, spreading it evenly with the spatula. Bake in the preheated oven for 50-60 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean or with a few moist crumbs.

The edges will pull away slightly from the pan when done. If the top browns too quickly, tent the pan loosely with aluminum foil to prevent over-browning while the center finishes cooking.

Step 5: Cool and Serve

Remove the pan from the oven and let the mochi cool in the pan for 10 minutes. Then, transfer it to a wire rack to cool completely. This cooling step is essential to allow the texture to set properly.

Once fully cooled, cut into squares and serve. The mochi will have a slightly crisp top with a dense, chewy interior. Store leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for up to 1 week.

Essential Equipment for This Dish

Essential Baking Pan

A 9×13-inch baking pan is non-negotiable for this recipe—it provides the perfect thickness for that signature chewy texture. I prefer light-colored metal pans for even baking. Glass works too but may require 5-10 extra minutes of baking time. 💡

Mixing Bowls

Use two medium bowls: one for wet ingredients and one for dry. I recommend stainless steel for durability and easy cleaning. A whisk is essential for smoothing out the sugar-butter mixture before adding eggs.

Spatula Matters

A silicone spatula ensures you scrape every bit of precious batter into your pan. I like the OXO Good Grips brand—it’s heat-resistant and flexible enough to fold in the coconut without overmixing.

Toothpick Test

Don’t skip the toothpick test at 50 minutes—it’s the only reliable way to check doneness. The center should come out clean or with a few moist crumbs. If it’s wet, give it another 5-10 minutes.

Cooling Rack

Transferring to a wire cooling rack after 10 minutes prevents soggy bottoms. This step is crucial for achieving that perfect balance of crisp edges and chewy center. I learned this the hard way after my first few batches stuck. 🌟

Optional Parchment

For easy removal, line your pan with parchment paper before greasing. It’s not traditional, but I’ve found it prevents sticking, especially with glass pans. Just leave an overhang on two sides for simple lifting.
