This powdered donut recipe is for a baked donut covered in confectioners' sugar.
Preheat oven to 425 degrees F.
Coat a donut pan with non-stick cooking spray.
In a large mixing bowl, sift together the flour, sugar, baking powder, nutmeg and salt. Whisk in the buttermilk, eggs and butter until combined.
Fill each donut cup about 2/3 the way full.
Bake for about 8 minutes or until the donuts are springy. Cool in the pan for about 5 minutes before removing.
Once cooled, place the confectioners' sugar in a resealable plastic bag along with the donuts and shake to coat.
