01 - Whisk together sweet rice flour, almond flour, baking powder, and salt in a large bowl until thoroughly combined.
02 - In a separate bowl, combine milk, sugar, ube halaya, eggs, melted butter, and vanilla extract. Whisk until mixture is smooth and uniform.
03 - Pour wet ingredients into dry ingredients. Stir continuously until a thick, sticky dough forms and all dry pockets are incorporated.
04 - Lightly dust hands with rice flour. Roll dough into 1.5-inch balls. Arrange 8 balls in a ring pattern on parchment paper squares, pressing gently to seal seams.
05 - Heat oil to 340°F in a deep pot. Carefully lower donuts on parchment into hot oil. Fry for 2-3 minutes per side until puffed and golden. Remove parchment after 30 seconds.
06 - Transfer fried donuts to wire rack lined with paper towels. Allow to drain and cool for 10-15 minutes until glazing temperature.
07 - Whisk powdered sugar, ube halaya, milk, and salt until 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.
