Preheat oven to 350 °F.
In a medium bowl, combine sweet rice flour, brown sugar, baking powder, and salt.
In a large bowl, whisk coconut oil, egg, coconut milk, and vanilla extract together.
Pour the wet ingredients into the dry ingredients and whisk until the batter is smooth.
Lightly grease a donut pan with oil spray and pour the batter in each cavity to ¾ full.
Bake the donuts at 350 °F for 30-35 min.
Once baked, remove the donuts from the pan and place them on a cooling rack.
To make each glaze, whisk together the ingredients. Once the donuts are cooled, dip the donuts in each glaze, decorate the donuts, and allow the glaze to harden while the donuts are on a cooling rack. Enjoy the donuts once the glaze has hardened.
