In a large mixing bowl, sift together the All-purpose wheat flour, Glutinous rice flour, Granulated sugar, Baking powder, and Fine sea salt. Whisk well to combine all dry ingredients evenly.

In a separate bowl, whisk together the Whole milk, Large egg, and melted Unsalted butter until thoroughly combined.

Gradually pour the wet mixture into the dry ingredients, whisking continuously until a smooth, lump-free batter is formed. Do not overmix. Cover the bowl and let the batter rest at room temperature for 15 minutes.
