Homemade Hawaiian Butter Mochi (Print version)

Chewy, buttery Hawaiian mochi squares made with mochiko, coconut milk, and a golden coconut top.

# Ingredients:

For the pan

01 - 1 tablespoon softened butter or neutral oil, for greasing

For the butter mochi

02 - 1 lb (454 g) mochiko sweet rice flour
03 - 2 cups (400 g) granulated sugar
04 - 2 teaspoons baking powder
05 - 1/2 teaspoon kosher salt
06 - 4 large eggs, room temperature
07 - 1 can (13.5 oz or 400 ml) full-fat coconut milk
08 - 1 can (12 oz or 354 ml) evaporated milk
09 - 1/2 cup (113 g) unsalted butter, melted and cooled slightly
10 - 2 teaspoons vanilla extract
11 - 1 cup (85 g) sweetened shredded coconut, divided

# Instructions:

01 - Heat the oven to 350°F. Grease a 9x13-inch metal baking pan with softened butter or neutral oil, coating the corners well.
02 - In a large bowl, whisk the mochiko, sugar, baking powder, and salt until evenly mixed and free of large lumps.
03 - In a separate bowl, whisk the eggs, coconut milk, evaporated milk, melted butter, and vanilla until smooth.
04 - Pour the wet mixture into the dry ingredients. Whisk until the batter is smooth and glossy, then stir in 1/2 cup of the shredded coconut.
05 - Pour the batter into the prepared pan. Tap the pan on the counter a few times to release large bubbles, then sprinkle the remaining 1/2 cup shredded coconut evenly over the top.
06 - Bake for 60-70 minutes, until the top is golden brown, the edges are browned, and the center feels set. Tent loosely with foil near the end if the coconut browns too quickly.
07 - Cool completely on a wire rack for at least 1 hour. Cut into 24 squares with a lightly greased plastic knife, wiping the knife as needed.

# Good to know:

01 - Texture is best after cooling fully and even better after resting several hours.
02 - Use mochiko sweet rice flour, not regular rice flour.
03 - Store airtight at room temperature for about 2 days or refrigerate for longer storage.
