1.Preheat oven to 350 degrees, spray a nonstick donut pan with cooking or baking spray and set aside.
2.In a large mixing bowl, combine all dry batter ingredients. Use a whisk to break up any clumps and to combine well. In a small mixing bowl, combine wet batter ingredients.
3.Pour the wet ingredients into the dry and with a rubber spatula mix gently to combine. Be sure to dig deep to incorporate all the dry into the wet but try not to over mix the batter.
4.Spoon batter into prepared pan. Bake for about 8 to 10 minutes. Turn pan around after 5 minutes.
5.Take out and let cool on wire rack for about 10 minutes. While the muffins are cooling, melt butter. Mix the cinnamon and sugar in a small cereal bowl. Invert the donuts and let cool a few minutes. When cool enough to handle, dip or brush each donut with melted butter then dip into cinnamon sugar mixture. Let set up on serving plate for just a few minutes. Enjoy!
