Preheat the oven to 400 F and prepare a donut pan or silcone donut mold with non-stick spray (be generous if using a pan).
Place all the dry ingredients into a mixing bowl and stir until combined. Add in all of the wet ingredients and stir just until the batter comes together. It will be thick! Transfer the batter to a piping bag or plastic zip bag and cut the corner to create your own piping bag and fill 3 donut molds. Bake the donuts for 9-10 minutes. Let cool.
Stir together the glaze, add more almond milk if needed. Dip each donut in the glaze and top with sprinkles!
These donuts are best if kept lightly covered at room temperature for 2 days or in the refrigerator for 4 days.
