In a large mixing bowl, combine glutinous rice flour, wheat flour, baking powder, salt, and granulated sugar (for the dough). Whisk these dry ingredients thoroughly to ensure even distribution.

Gradually add hot water to the dry ingredients, mixing with a sturdy spatula or spoon until a shaggy, crumbly dough begins to form.

Add cooking oil (for the dough) to the mixture. Transfer the dough to a clean, lightly oiled surface and knead by hand for about 10-15 minutes until the dough becomes smooth, elastic, and no longer sticky. Cover the kneaded dough with a damp cloth and let it rest for 15 minutes at room temperature.
