Butter mochi sits at the core of Hawaii's favorite comfort sweets, giving you that amazing mix of chewiness, sweetness, and coconut flavor in each bite. You'll find this treat at every local get-together across the islands, hitting that sweet spot between vanilla yumminess and tropical coconut vibes, all wrapped up in a texture that'll make you smile with every mouthful.

This recipe has been in my family for ages. I can still picture myself next to my grandma as she showed me her trick of knocking the pan to get that smooth, bubble-free finish. Whenever I whip this up now, the smell of vanilla and coconut instantly takes me back to those special times in her kitchen.

Key Recipe Elements

  • Mochiko sweet rice flour: Makes that one-of-a-kind chewy feel that butter mochi is famous for, try to grab the package with the blue star for the real deal
  • Full fat coconut milk: Brings creaminess and real island taste, go for ones without extra stuff for the cleanest flavor
  • Quality unsalted butter: Gives that wonderful melt-in-your-mouth sensation, make sure it's soft before you use it
  • Large fresh eggs: Add body and richness, let them sit out a bit first
  • Pure vanilla extract: Makes everything taste better, don't use the fake stuff
  • Granulated sugar: Cuts through the richness and helps form that tasty crust
  • Unsweetened shredded coconut: Throws in a nice texture difference

Making Your Butter Mochi

Getting Ready:
Set your oven to 350°F (175°C), with the rack right in the middle. Rub butter all over a 9x13 inch metal baking pan, making sure you don't miss any spots.
Mix Dry Stuff:
Stir together mochiko flour, sugar, and baking powder in a big bowl until they're totally mixed.
Fix Up Wet Stuff:
Beat room temperature eggs, vanilla, and milk together until they look smooth.
Put It All Together:
Add the wet stuff to your dry mix, stirring until it's all combined. Pour in melted butter and coconut milk, mixing till it looks silky. Pour into your pan, tap it a few times to get rid of bubbles, and sprinkle coconut evenly on top.
Oven Time:
Bake until you see golden edges and the middle feels firm when you touch it gently. Let it cool all the way before cutting into squares.

In my home, butter mochi has become our go-to celebration treat. My kids especially love helping stir the mixture, and seeing them smile when they taste it makes every batch worth making. This simple dessert has brought so much happiness to our family get-togethers.

Tasty Serving Suggestions

Make your butter mochi even better by eating it with fresh tropical fruits like mango or pineapple. Try it with some Hawaiian coffee for a real island morning treat. For parties, you might want to make a platter with different flavors so your guests can try a bit of everything.

Ways To Switch It Up

Try adding matcha powder for a Japanese-inspired twist with earthy notes. Switch vanilla for coconut extract if you want an extra tropical kick. Mix in some purple sweet potato paste for a stunning ube version that keeps that awesome chewy texture while adding beautiful color and new flavors.

How To Keep It Fresh

Your butter mochi will stay tasty in an airtight container at room temp for about three days. Don't put it in the fridge as this can mess up its chewiness. If you want to save it longer, wrap each piece in plastic and freeze for up to a month, then just let them sit out when you're ready to eat them.

I first learned about butter mochi in my grandma's kitchen, where she taught me that taking your time and paying attention to the little things creates the perfect texture. I still use her old wooden spoon for mixing, since I believe it carries years of love that makes each batch extra special. This isn't just a dessert. It's about Hawaiian friendliness, family traditions, and the joy of sharing something truly wonderful with people you care about.

02 8 tablespoons (1 stick) unsalted butter, melted
03 16 ounces (1 pound) mochiko (sweet rice flour)
04 2 cups white sugar
05 2 teaspoons baking powder
06 1/2 teaspoon salt (kosher is best)
07 2 cups of any milk (whole, low-fat, or skim)

10 1 can (13.5 oz) coconut milk, unsweetened

→ On Top

11 1/2 cup shredded coconut (unsweetened)
12 Optional: flaky sea salt to finish

Instructions

Step 01

Move the oven rack to the center position and heat the oven to 350°F. Coat a 9x13-inch pan generously with oil or butter. Melt the butter and leave it aside.

Step 02

In a big bowl, stir together the mochiko flour, sugar, salt, and baking powder until it’s one mixture.

Step 03

Use a medium bowl to whisk together eggs, milk, and vanilla until it’s smooth and all mixed up.

Step 04

Add the wet mix to the dry ingredients and stir with a wooden spoon until well blended. Pour in the melted butter and coconut milk, mixing until the batter is smooth and even.

Step 05

Transfer the batter to your greased pan. Gently tap the pan against the counter to let out air bubbles.

Step 06

Scatter the shredded coconut evenly across the batter in small handfuls. Sprinkle a bit of flaky salt on top, if you'd like.

Step 07

Pop it into the oven and bake for 60-70 minutes. It’s ready when the top turns golden and the center is firm.

Step 08

Let the pan cool completely on a wire rack for an hour. Use a greased plastic knife to cut into 20 rectangles, about 2 1/4 by 2 1/2 inches each.
