01 - Whisk together sweet rice flour, almond flour, baking powder, and salt in a large mixing bowl until thoroughly blended.
02 - In a separate bowl, whisk milk, sugar, ube halaya, eggs, melted butter, and vanilla extract until completely smooth and uniform.
03 - Pour wet ingredients into dry ingredients. Stir continuously until a thick, sticky dough develops and no dry streaks remain.
04 - Lightly coat hands with rice flour. Roll dough into 1.5-inch balls. For traditional ring shape, arrange 8 balls in a circle on parchment squares, pressing gently to secure.
05 - Heat oil in deep pot to 340°F. Lower donuts on parchment into hot oil. Fry 2–3 minutes per side until puffed and golden. Remove parchment after 30 seconds.
06 - Transfer donuts to wire rack lined with paper towels. Allow to cool for 10–15 minutes until glaze can be applied without melting.
07 - Whisk powdered sugar, ube halaya, milk, and salt until completely smooth and pourable. Adjust consistency with additional milk if needed.
08 - Dip tops of cooled donuts into glaze, allowing excess to drip off. Place on wire rack and let set for 10–15 minutes before serving.
