Preheat oven to 350 degrees F. Spray a donut pan with an all-natural cooking spray, even if it's a nonstick pan.Mix all of the dry donut ingredients in a large mixing bowl. Mix all of the wet donut ingredients in a medium mixing bowl. Add the wet ingredients to the dry and stir to combine. Do not overmix.Spoon batter evenly into donut pan or transfer batter to a baggie with one corner cut off, to allow for squeezing the batter out of the baggie and into the shape of a donut on the donut pan. You will have enough batter for 7 donuts.Bake for 20 minutes.While donuts are baking, prepare ingredients for glaze. Wait to warm the glaze, though, until after donuts have baked and cooled.For the glaze, whisk ingredients in a shallow bowl and heat in the microwave in 30 second increments. Whisk each time you check the ingredients, until they are completely melted.When donuts have cooled for approximately 10 minutes, transfer them to wire cooling rack. Dip each donut into the heated glaze. Decorate with sprinkles if you like and enjoy!
