This butter mochi muffin recipe transforms the beloved Hawaiian dessert into convenient, handheld treats. The combination of glutinous rice flour with rich coconut milk creates that signature chewy texture while maintaining a delicate sweetness that makes these utterly irresistible.
The first time I made these muffins for a neighborhood potluck, they disappeared faster than any other dessert. Now I keep a box of Mochiko flour in my pantry at all times because my family requests these weekly.
Ingredients
- Unsalted butter: Provides richness and helps create a tender crumb
- Granulated sugar: Balances the flavors without overwhelming sweetness
- Large eggs: At room temperature incorporate better for proper structure
- Vanilla extract: Adds depth and warmth to complement the coconut
- Mochiko flour: This glutinous rice flour creates that signature chewy texture
- Baking powder: Gives just enough lift while maintaining density
- Evaporated milk: Adds creamy richness without thinning the batter
- Coconut milk: Provides that tropical flavor that makes mochi special
Step-by-Step Instructions
- Prepare Your Workspace:
- Preheat your oven to 350°F and prepare your muffin tins with paper liners or a thorough coating of butter. I find silicone baking cups work exceptionally well for this recipe as they release the mochi muffins perfectly without sticking.
- Create Your Base:
- In a large mixing bowl, combine the melted butter and sugar, stirring until fully incorporated. The mixture should look smooth but not overly fluffy. This is different from traditional cake method as we want density rather than air incorporation.
- Build The Structure:
- Add eggs one at a time, ensuring each is fully incorporated before adding the next. This gradual addition prevents the batter from breaking and helps create the proper texture. The mixture will become smoother and more pale with each egg addition.
- Enhance The Flavor:
- Stir in the vanilla extract thoroughly. While it may seem like a small addition, this aromatic ingredient ties together the dairy and coconut notes beautifully, creating a more complex flavor profile.
- Develop The Texture:
- Add the Mochiko flour and baking powder, stirring until about 80-90% combined. Avoid overmixing at this stage to prevent developing too much gluten which would make the muffins tough rather than chewy.
- Complete The Batter:
- Pour in both the evaporated milk and coconut milk, stirring until the mixture becomes completely smooth. Take your time with this step, ensuring there are absolutely no lumps in your batter which could affect the final texture.
- Bake To Perfection:
- Fill each muffin cavity about 3/4 full and bake for 45 minutes. The muffins are done when a tester comes out with minimal dry crumbs. The tops should be golden brown with a slight dome and may have a crackly appearance.
- Cool With Patience:
- Allow the muffins to cool in the pan for about 10 minutes before transferring to a wire rack. Complete cooling is important as the texture continues to develop as they cool.

The coconut milk is truly the secret weapon in this recipe. I discovered its importance when I once tried substituting regular milk in a pinch. While still tasty, they lacked that distinctive tropical aroma and depth that makes butter mochi truly special.
Storage Solutions
These butter mochi muffins actually improve with time as the flavors meld together. Store them in an airtight container at room temperature for up to three days. The texture will remain perfectly chewy without drying out. For longer storage, refrigerate for up to a week, bringing to room temperature before serving. You can also freeze them for up to three months by wrapping individually in plastic wrap and placing in a freezer bag.
Flavor Variations
The base butter mochi recipe is wonderfully adaptable. Try adding 1/2 cup shredded coconut for extra texture, or fold in 1 cup of fresh blueberries for a fruity version. For chocolate lovers, mix in 1/3 cup mini chocolate chips or 2 tablespoons of matcha powder for a Japanese-inspired twist. During fall, I love adding 1 teaspoon of cinnamon and 1/4 teaspoon of nutmeg for a warming spice profile.
Cultural Context
Butter mochi originated in Hawaii as a fusion dessert that combines Japanese mochi traditions with Western baking techniques. The dessert represents Hawaii's multicultural heritage, particularly the influence of Japanese immigrants who arrived to work on sugar plantations. Traditional mochi in Japan is pounded rice cake, but this baked version became popular in Hawaiian homes as an easier preparation method that maintained the beloved chewy texture while incorporating local ingredients like coconut.

The result is buttery, chewy, and irresistible muffins that honor the Hawaiian spirit while remaining easy enough for anyone to master.
Frequently Asked Questions
- → What is Mochiko flour and can I substitute it?
Mochiko flour is a brand of glutinous rice flour, which gives these muffins their distinctive chewy texture. You can substitute with any brand of glutinous rice flour (sometimes labeled sweet rice flour). Regular rice flour won't work as it lacks the sticky properties needed for authentic mochi texture.
- → Why are my mochi muffins too dense?
Dense mochi muffins usually result from overmixing the batter or inaccurate measurements. Ensure you're using the correct ratio of wet to dry ingredients and mix just until the batter is smooth. Also, check that your baking powder is fresh, as expired leavening agents won't provide proper rise.
- → How should I store butter mochi muffins?
Store cooled mochi muffins in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week. They can also be frozen for up to 3 months. Warm slightly before serving for the best texture.
- → Can I add other flavors to these muffins?
Absolutely! Butter mochi muffins are versatile. Try adding matcha powder, black sesame paste, cocoa powder, or citrus zest. You can also top with shredded coconut, a sprinkle of kinako (roasted soybean flour), or a light dusting of powdered sugar for variation.
- → Why did my mochi muffins sink in the middle?
Sinking can occur if the muffins are underbaked or if the oven temperature is too high. Ensure you're baking at the correct temperature and check for doneness with a toothpick. Another common cause is opening the oven door too early during baking, which causes a sudden temperature drop.
- → What's the difference between butter mochi muffins and traditional mochi?
Traditional mochi is made by pounding steamed glutinous rice into a sticky paste, while butter mochi muffins are baked using glutinous rice flour combined with butter, sugar, eggs, and milk. The muffins have a cake-like quality while maintaining the chewy texture characteristic of mochi.
