The Mochiko flour is non-negotiable—look for the blue box at Asian markets or the international aisle of Walmart. Most brands are interchangeable, but Koda Farms is the gold standard. The coconut milk should be full-fat for that rich, authentic flavor. Canned works better than carton for this application. Don’t substitute regular rice flour; the texture won’t be the same.

No coconut milk? Coconut cream thinned with water (1:1 ratio) works in a pinch. For a lighter version, half the butter can be replaced with coconut oil, but the flavor will shift slightly. The eggs are essential for structure, but if you must, flax eggs (4 tbsp ground flax + 10 tbsp water) can be used—though texture will differ. Always use a metal pan for even baking.

This keeps beautifully at room temperature for 3 days in an airtight container. For longer storage, refrigerate for up to 1 week or freeze for 3 months. Slice before freezing for easy single servings. Reheat briefly in the microwave for that just-baked warmth.

Step-by-Step Instructions for Butter Mochi

Master the technique for this Hawaiian favorite with these precise, tested steps.

Step 1: Prepare the Wet Ingredients

Begin by melting the 0.5 cup Unsalted Butter in a microwave-safe bowl, then allow it to cool slightly. In a large mixing bowl, whisk together the melted butter, 1.5 cups Granulated Sugar, and the 4 whole Large Eggs until fully combined and smooth.

Add the 1 can Coconut Milk and 2 tsp Vanilla Extract, whisking again until the mixture is uniform. The coconut milk should be at room temperature to prevent the butter from solidifying. This wet base ensures a rich, moist texture in the final product.

Step 2: Combine the Dry Ingredients

In a separate medium bowl, sift together the 1 lb Mochiko Sweet Rice Flour, 1 tsp Baking Powder, 0.5 tsp Salt, and 2 tbsp Cornstarch. Sifting removes lumps and aerates the flour for a lighter consistency.

Add the 0.5 cup Shredded Coconut to the dry mixture and stir to distribute evenly. This step ensures the coconut is well incorporated throughout the batter, providing bursts of texture and flavor in every bite. The cornstarch enhances the chewy texture characteristic of authentic mochi.

Step 3: Mix and Prepare the Batter

Gradually add the dry ingredient mixture to the wet ingredients, whisking gently after each addition until no lumps remain. Avoid overmixing—just combine until the batter is smooth and uniform. The batter will be thick but pourable, similar to a cake batter.

Let the batter rest for 5 minutes to allow the Mochiko Sweet Rice Flour to fully hydrate. This resting period is crucial for achieving the signature chewy texture. You’ll notice the batter thickens slightly as it sits.

Step 4: Bake to Golden Perfection

Preheat your oven to 350°F and grease a 9×13-inch baking dish with a thin layer of oil or nonstick spray. Pour the batter into the prepared dish, spreading it evenly with a spatula. The top should be smooth and level.

Bake on the middle rack for 50-60 minutes, or until the edges pull away from the pan and the top is golden brown. A toothpick inserted into the center should come out clean or with a few moist crumbs. The surface will develop a slightly crisp crust, while the interior remains soft and chewy.

Step 5: Cool and Serve

Remove the mochi from the oven and let it cool in the pan for 10 minutes. This brief cooling period allows the structure to set, making it easier to slice. The texture will firm up slightly as it cools but will remain delightfully chewy.

Cut into squares while still warm, as the mochi is easiest to slice at this stage. Serve warm or at room temperature. For best results, store leftovers in an airtight container at room temperature for up to 3 days, though it’s so delicious it rarely lasts that long.

Perfect Pairings for This Dish
