Butter mochi is one of Hawaiʻi’s most loved local desserts. It combines the chewy texture of Japanese mochi with the rich flavor of butter cake, creating a unique treat that is crispy around the edges and soft in the center. Found at family gatherings, potlucks, bakeries, and local celebrations across the islands, butter mochi has become a comfort food that many visitors end up searching for after returning home.

I. What Is Butter Mochi?

Unlike traditional Japanese mochi made by pounding sticky rice, Hawaiian butter mochi uses sweet rice flour (mochiko flour) as its base ingredient. The addition of butter, coconut milk, eggs, and sugar creates a dessert that sits somewhere between cake and mochi.

Its popularity in Hawaiʻi reflects the islands' blend of cultures, where local foods often combine influences from different traditions into something completely new.

II. Ingredients You’ll Need

Ingredients commonly used in homemade butter mochi.

For a classic homemade butter mochi recipe, gather:

• 1 box (16 oz) mochiko sweet rice flour
• 1 cup melted butter
• 2 cups sugar
• 4 eggs
• 1 can (13.5 oz) coconut milk
• 1 can evaporated milk
• 1 teaspoon vanilla extract
• 2 teaspoons baking powder

These ingredients are commonly available at most grocery stores.

III. Step-by-Step Butter Mochi Recipe

Step 1: Prepare the oven

Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking pan.

Step 2: Mix wet ingredients

In a large bowl, whisk together:

• Melted butter
• Eggs
• Coconut milk
• Evaporated milk
• Vanilla extract

Mix until smooth.

Step 3: Add dry ingredients

Slowly add:

Mochiko flour

Sugar

Baking powder

Whisk until no lumps remain.

Step 4: Bake

Pour the batter into your prepared pan and bake for 50–60 minutes, or until the top turns golden brown and the edges become slightly crispy.

Step 5: Cool before slicing

Allow the butter mochi to cool completely before cutting into squares. This helps the texture become perfectly chewy.

IV. Tips for the Perfect Chewy Texture

A few small adjustments can make a noticeable difference:

• Avoid overbaking, as it can make the dessert dry.
• Let the mochi cool fully before slicing.
• Use full-fat coconut milk for richer flavor.
• Grease the pan well to prevent sticking.

The ideal butter mochi should have a slightly crisp top layer with a soft and stretchy center.

Matcha Butter Mochi
