What Is Butter Mochi?

“Bata Mochi,” also known as Butter Mochi, is a naturally gluten free Hawaiian local treat. You may be surprised how easy this butter mochi recipe is to make. Hawaiian mochi cake is naturally gluten-free; our kids love it as a snack or dessert.

A lot of people have never heard of butter mochi. Think of it like a baked custard made with sweet rice flour. Butter mochi is a soft cake made with coconut (or regular) milk, sweet rice flour, sugar, and eggs.

When Chef Nagano of Skool restaurant in San Francisco shared her amazing gluten free Black Sesame Banana Bread recipe with me, she also shared her Auntie Ellen’s family mochi recipe. I knew this was special and asked if I could write up this recipe for the blog.

If you haven’t tried mochi, this super easy butter mochi recipe is worth trying. Soft and creamy, this butter mochi melts in your mouth. If you love this matcha recipe, wait until you try my matcha mochi recipe.

Why You Need To Try Mochi:

  1. This mochi recipe is seriously good! It is made with very few ingredients, and it tastes delicious!
  2. This is the best Mochiko flour recipe.
  3. The creamy texture and flavor can’t be beaten! My mochi recipe is lightly sweet and has a subtle coconut flavor.
  4. This mochi tastes like you are on a tropical vacation in Hawaii! Every time I make it, I fondly remember our Hawaiian vacation.

Ingredient Notes:

  • Sweet rice flour – Also called Mochiko. Mochiko is the ingredient that gives this Hawaiian butter mochi its creamy texture. DO NOT substitute this with regular rice flour or brown rice flour, or your mochi will not turn out. Trust me on this. You can find sweet rice flour at many grocery stores. I prefer this brand by Koda Farms.
  • Milk – I prefer to use coconut milk because it adds a little sweetness and flavor. You can use regular milk if you prefer, but the flavor will not have the famous light creamy coconut taste.
  • Butter – Use unsalted butter. For dairy-free, use vegan butter!
  • Eggs – Size Large.
  • Baking powder – Be sure to use aluminum-free baking powder!

How to Make Hawaiian Butter Mochi:

The mochi dry ingredients.

Step 1: Set the oven rack to the middle and preheat the oven to 325º F. Add the sweet rice flour (Mochiko), cane sugar, and other dry ingredients to a large bowl or standing mixer.

The mochi wet and dry ingredients.

Step 2: Add your coconut milk, eggs, and melted butter to a small mixing bowl. Pour the wet ingredients into the dry ingredients and mix.

If you are using a standing mixer, add the wet ingredients to the dry ingredients in the bowl. Be sure to use the paddle attachment.

Step 3: Use a spoon to mix the wet and dry ingredients in the mixing bowl.

Step 4: You can either grease an 8×8 pan or line the pan with parchment paper. This butter mochi is easier to remove from the pan using parchment paper.

Carefully pour the mochi batter into a greased 8×8 baking pan. Bake the mochi cake for 25 minutes. Remove the mochi from the oven.

TIP: Allow cooling before cutting the mochi cake! Due to the texture, it will stick to the knife if you slice the mochi while it is warm.

Mochi Tips and Recipe FAQ:

Is mochi gluten free?

Most mochi should be gluten free, but you will want to check the ingredients label every time!! Note the mochi at Whole Foods is not gluten free, at least in the Whole Foods near our store.

Does butter mochi need to be refrigerated?

Some people say bata mochi should be refrigerated, while others don’t. Refrigerating the gluten free butter mochi is fine, but it will dry it out a little bit. Please reheat it before serving or eating. I like to microwave it for a few seconds to warm it up.

How do you store Hawaiian mochi?

You can store your Hawaiian mochi on the countertop, but I really recommend storing it in the refrigerator. It will last for a few days. You will know when the mochi goes bad because it will seem dry, hard, and potentially have mold.

Can you freeze mochi?

Yes, you can freeze Hawaiian butter mochi. It’s best to wrap the gluten free butter mochi in individual-sized pieces with plastic wrap. Then, place it in a freezer bag or other airtight container. It will last around 1 month in the freezer. Toss it in the microwave for a few seconds when you are ready to serve.

Can you make mochi in a cupcake pan?

Yes, you can make butter mochi in a cupcake pan. This is ideal if you are serving a crowd and want individual portions. Just follow the instructions as directed.

They don’t take as long to cook when they are in cupcake tins unless you fill each section full. A muffin tin filled no more than 1/2 way should take about 30 minutes but up to 45 minutes if filled higher.

Does shredded coconut taste good in butter mochi?

If you love coconut, you should try adding some shredded coconut. Put up to 1 cup of shredded coconut into the batter. You can go a little bit less if you want a subtle coconut texture. Another option is to toast some coconut and put it on top. Either way, it’s really.

What does mochi taste like?

Mochi is sweet and chewy. Hawaiian butter mochi has a sweet, buttery flavor.

What is the difference between Japanese mochi and Hawaiian Butter Mochi?

Japanese mochi is typically filled with a sweetened mung bean or other fillings, while Hawaiian mochi is baked cake style without a filling.

Mochiko Substitute:

As much as I wish there were a good Mochiko substitute, there really isn’t. Some recipe sites will say to use potato or cornstarch, but I tested those replacements, which tasted like garbage. (Sorry, just the truth.) Mochiko is special, and it really can’t be replaced.

The good news is you can find Mochiko at many grocery stores and online.

  1. I made both the Matcha mochi and the Hawaiian mochi. They both tasted delicious but they didn’t look like yours. Mine were much thinner and flat. I thought of using baking soda to lift them the second go round but didn’t have any. What happened. Any ideas? I did use Lite coconut milk and Swerve natural sweetener in place of the sugar.

    1. Hi Catherine, I have not tested Swerve in any of my recipes, I do not use it, so I do not know how it behaves in baking compared to sugar. I recommend checking to see if your baking powder is expired, that is often a big reason for things not rising.

  2. My grandparents pounded fresh mochi every New Year. One of my favorite desserts at my grandmother’s was Zenzai Sweet Red Bean Soup with Mochi. Every New Year morning we had fried mochi with a slather of butter and a sprinkle of sugar or kinako.

    Living in the Inland Northwest, fresh mochi is not available. This year, my mochi-loving 11-year-old granddaughter and I used your Butter Mochi recipe- it was a big hit with the family. She asked for the recipe so she can make it for her family!
