Preheat oven to 350 degrees F
Heat the milk in a sauce pan for about a minute. Once milk is warm, pour over earl grey tea and let steep for 10 minutes.
In a large bowl, mix together the rice flour, baking powder, and earl grey tea powder. Set aside.
In a separate medium bowl, whisk together the butter, vanilla extract, and sugar. Add in the eggs and whisk until combined. Finally, add in the earl grey milk from step 2 and whisk.
Pour the wet ingredients into the large bowl with the dry ingredients. Use a spatula to combine until you get a thick dough.
Spoon the dough into a pastry bag or use a ziploc bag to pipe the dough into a donut pan. I used a donut pan with donut molds that are 3 inches in diameter.
Grease the donut pan. Pipe your batter into the donut molds.
Bake for about 7-9 minutes.
Make the glaze. Add all the ingredients for the glaze into a small bowl and whisk together.
Once the donuts are out of the oven, cool for 20 minutes.
Dip donuts into the glaze and put them on a cooling rack to dry. It should take about 20 minutes for the glaze to fully dry.
