01 - Preheat the 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 the sweet rice flour, sugar, baking powder, and salt until evenly blended.
03 - In a separate bowl, whisk the coconut milk, whole milk, eggs, melted butter, and vanilla extract until smooth and fully incorporated.
04 - Pour the wet ingredients into the dry ingredients. Stir with a spatula or whisk until fully combined and smooth—avoid overmixing to prevent tough texture.
05 - Pour the batter into the prepared baking pan and gently tap the pan on the counter to release trapped air bubbles.
06 - Sprinkle the shredded coconut evenly over the surface of the batter.
07 - Bake for 55 to 60 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out mostly clean with a few moist crumbs.
08 - Cool completely in the pan on a wire rack before slicing into squares or bars. This allows the cake to set properly for cleaner cuts.
