01 - Preheat oven to 350°F. Lightly grease a 9x13-inch baking pan and line with parchment paper for easy removal.
02 - In a large mixing bowl, whisk together sweet rice flour, granulated sugar, baking powder, and fine salt until evenly distributed.
03 - In a separate bowl, whisk coconut milk, whole milk, eggs, melted butter, and vanilla extract until completely smooth and emulsified.
04 - Pour wet ingredients into dry ingredients. Stir with a spatula or whisk until fully combined and smooth—avoid overmixing to prevent tough texture.
05 - Transfer batter to the prepared baking pan. Gently tap the pan on the counter several times to release trapped air bubbles.
06 - Sprinkle shredded coconut evenly across the entire surface of the batter.
07 - Bake for 55 to 60 minutes, until edges are golden brown and a toothpick inserted in the center comes out mostly clean with moist crumbs.
08 - Cool completely in the pan on a wire rack before slicing into squares or bars. This allows the texture to set properly.
