Mix 1/4 cup tapioca starch, 3/4 cup glutinous rice flour, and 1/4 cup cheese powder in a bowl. Add 2 tsp melted unsalted butter and mix well. Then add 1 beaten egg and mix thoroughly. Gradually add 1/4 to 1/3 cup milk until the dough comes together (adjust the milk amount based on the dough's consistency). Add 1/4 cup grated Parmesan cheese.

Shape the dough into balls and bake in a preheated oven at 400°F (200°C) for 15 minutes. Done.
