Gluten Free Baked Donut

I found this recipe on Pinterest and thought it would be an easy recipe to make GF. It tastes more like a vanilla muffin not so much like a donut, but sure is tasty none the less. 

3/4 cup sugar
1 egg
1/4 cup vegetable oil
3/4 cup milk (made one batch with rice milk to good results)
1 teaspoon vanilla
1 1/2 cups gluten free flour (1 1/4 cup brown rice, 1/4 cup sorghum flour)
2 teaspoons baking powder
1/4 teaspoon salt
1/2 teaspoon xanthum gum
Coating
2 tablespoons butter, melted (optional)
1/2 cup superfine sugar (can pulse regular sugar in food processor to make), or powdered sugar

• Lightly grease a muffin tin with vegetable oil or spray.
• In a large bowl, beat together sugar and egg until light in color. Add vegetable oil, milk, and vanilla to sugar mixute and combine.
• In a seperate bowl, combine flour, baking powder, salt, and nutmeg. Then pour into liquid mixture and stir to combine.
• Fill muffin cups 3/4 full, and bake in a 350 degree preheated oven for 18-20 minutes, or until a tester inserted in the middle comes out clean.
