Ingredients for Hawaiian Butter Mochi

You’ll need:

1 box mochiko sweet rice flour, 16 ounces
2 cups sugar
2 teaspoons baking powder
1/2 teaspoon salt
4 large eggs
2 cups whole milk
1 can coconut milk, 13.5 ounces
1/2 cup melted butter
2 teaspoons vanilla extract

Optional toppings:

Shredded coconut
Powdered sugar
Sesame seeds
Extra melted butter for brushing

Mochiko flour is the most important ingredient in this recipe. Do not replace it with regular rice flour or all purpose flour, because the texture will not be the same. Sweet rice flour gives butter mochi its classic chewy texture.

What Makes Butter Mochi Special?

Butter mochi is special because it has a texture that is somewhere between cake, custard, and chewy mochi. The edges become slightly golden and firm, while the inside stays soft, smooth, and stretchy.

The coconut milk gives it a gentle tropical flavour, while the butter makes it rich and comforting. It is simple enough for everyday baking but special enough for parties and gatherings.

Unlike many cakes, butter mochi does not need frosting or filling. The flavour and texture are already delicious on their own.

Step by Step Hawaiian Butter Mochi Recipe

Step 1: Prepare the Baking Pan

Preheat your oven to 350°F. Grease a 9×13 inch baking pan with butter or nonstick spray.

You can also line the pan with parchment paper if you want to lift the mochi out easily after baking. This helps when cutting neat squares.

Step 2: Mix the Dry Ingredients

In a large mixing bowl, add mochiko flour, sugar, baking powder, and salt.

Stir everything together until the dry ingredients are evenly combined. This helps the baking powder spread properly through the batter and gives the mochi an even texture.

Step 3: Mix the Wet Ingredients

In another bowl, whisk the eggs until smooth. Add whole milk, coconut milk, melted butter, and vanilla extract.

Mix well until the wet ingredients are fully combined. Make sure the melted butter is not too hot when adding it, because hot butter can cook the eggs.

Step 4: Combine Wet and Dry Ingredients

Slowly pour the wet mixture into the dry ingredients. Stir gently until the batter becomes smooth.

The batter will be thinner than regular cake batter, and that is normal. Keep mixing until there are no large lumps of flour.

If needed, use a whisk to make the batter smoother, but do not overmix too much.

Step 5: Pour into the Pan

Pour the batter into the prepared baking pan. Tap the pan gently on the counter to remove air bubbles.

If you want to add shredded coconut on top, sprinkle it evenly over the batter before baking. This gives the top a slightly toasted flavour and a pretty finish.

Step 6: Bake Until Golden

Bake the butter mochi for 55 to 65 minutes, or until the top is golden and the centre is set.

The edges should look lightly browned, and the top should have a smooth, slightly crackly surface. A toothpick inserted into the centre should come out mostly clean.

Do not worry if the mochi looks a little soft while hot. It will firm up as it cools.

Step 7: Cool Before Slicing

Let the butter mochi cool completely in the pan before cutting. This step is important because the texture needs time to set.

If you cut it too early, it may be too sticky or soft. Once cooled, slice it into squares using a sharp knife.

For cleaner cuts, lightly grease the knife or wipe it between slices.

Tips for the Best Hawaiian Butter Mochi

Use mochiko sweet rice flour for the right chewy texture.

Do not use regular flour, because it will make the recipe more like cake and less like mochi.

Let the mochi cool completely before slicing so the squares hold their shape.

Use full fat coconut milk for a richer flavour and better texture.

Do not overbake it too much, or the mochi can become dry around the edges.

Grease the pan well because mochi can stick easily.

For extra flavour, sprinkle shredded coconut on top before baking.

Easy Butter Mochi Variations

This classic Hawaiian butter mochi recipe is delicious on its own, but you can also change the flavour in simple ways.

For coconut butter mochi, add shredded coconut into the batter and sprinkle more on top.

For chocolate butter mochi, add cocoa powder or chocolate chips to the batter.

For matcha butter mochi, add a small amount of matcha powder for a green tea flavour.

For ube butter mochi, add ube extract or ube halaya for a sweet purple yam version.

For a slightly less sweet version, reduce the sugar a little, but do not remove too much because sugar also helps with texture.

What to Serve with Butter Mochi

Butter mochi tastes great on its own, but you can also serve it with simple drinks or toppings.

It pairs beautifully with coffee, tea, cold milk, iced latte, coconut milk, or hot chocolate.

For dessert tables, serve it with fresh fruit like strawberries, mango, pineapple, or berries. The fresh fruit balances the rich chewy texture of the mochi.

You can also dust a little powdered sugar on top before serving for a simple finish.

How to Store Hawaiian Butter Mochi

Store butter mochi in an airtight container at room temperature for up to 2 days.

For longer storage, keep it in the refrigerator for up to 5 days. The texture will become a little firmer when chilled, but it will still taste delicious.

To soften chilled butter mochi, let it sit at room temperature for a few minutes before serving. You can also warm it briefly in the microwave for a softer texture.

Can You Freeze Butter Mochi?

Yes, butter mochi can be frozen. Cut it into squares, wrap each piece tightly, and place them in a freezer safe bag or container.

Freeze for up to 2 months. When ready to eat, thaw at room temperature or warm gently in the microwave.

Freezing works well if you want to make a large batch and save some for later.
