Ingredients

Scale
  • Butter or vegetable oil, for greasing the pan

  • 1 stick (8 tablespoons) unsalted butter

  • 1 pound mochiko flour (sweet rice flour)

  • 2 cups granulated sugar

  • 2 teaspoons baking powder

  • 1/2 teaspoon kosher salt

  • 2 cups milk (any fat percentage)

  • 4 large eggs

  • 2 teaspoons vanilla extract

  • 1 can (13.5 oz) unsweetened coconut milk

  • 1/2 cup unsweetened shredded coconut

  • A few pinches of flaky salt (optional)

Instructions

Step 1:
Preheat your oven to 350°F and arrange a rack in the center. Grease a 9×13-inch baking dish with butter or oil.

Step 2:
Melt the butter in the microwave or on the stovetop, then set aside to cool slightly.

Step 3:
In a large bowl, whisk together the mochiko flour, sugar, baking powder, and salt.

Step 4:
In another bowl, whisk together the milk, eggs, and vanilla extract.

Step 5:
Pour the wet ingredients into the dry ingredients. Stir with a wooden spoon until well combined and smooth.

Step 6:
Add the melted butter and coconut milk to the batter. Stir until fully incorporated and silky.

Step 7:
Pour the batter into the greased baking dish. Tap the pan gently on the counter to release any air bubbles.

Step 8:
Sprinkle the shredded coconut evenly on top. Add a few pinches of flaky salt if using.

Step 9:
Bake for 60–70 minutes, or until the top is golden brown and the center is set.

Step 10:
Remove from the oven and cool completely on a wire rack (about 1 hour).

Step 11:
Cut into 20 squares using a plastic or greased knife to prevent sticking. Serve and enjoy!

Notes

  • Storage: Store in an airtight container at room temperature for up to 3 days.

  • Tip: If the knife sticks when slicing, rub it with a little butter or neutral oil.
