Equipment

Ingredients

Baked Oat Flour Donuts

  • 1⅓ cups oat flour
  • 2 teaspoons baking powder
  • ¼ teaspoon salt
  • ¼ cup milk
  • 1 large egg
  • ¼ cup white sugar
  • ½ teaspoon pure vanilla extract
  • 1 tablespoons oil (canola or vegetable oil)

Blueberry Glaze

  • ½ cup fresh or frozen blueberries
  • ½ cup water
  • ¾ cup powdered sugar (may need up to 1 cup)
  • 2 tablespoons butter (melted)

Optional Toppings

  • ½ cup fresh blueberries
  • 2 tablespoons chocolate sprinkles
  • 2 tablespoons pastel sprinkles

Instructions

  • Preheat the oven to 350° F. Grease the donut pans with cooking spray or a little oil on a brush. (If using 1 pan you will have to bake them in two batches).
  • Mix the oat flour, salt, and baking powder in a small bowl.
  • In a separate bowl add the milk, eggs, sugar, vanilla, and oil and mix well.
  • Add the dry ingredients to the wet ingredients and mix them together.
  • Carefully spoon in or use a pastry bag to fill the donut pan ¾ full.
  • Bake for 9-10 minutes. You can check with a toothpick to see if the center is done baking.
  • While they are cooling begin making the blueberry icing. Add ½ cup of blueberries to a small saucepan and cook over medium heat until the blueberries are soft and most of the liquid has evaporated.
  • Add the blueberries and any leftover water to a blender and blend them until they are smooth. Add it to a small bowl.
  • Once the blueberry mixture has slightly cooled add the butter and powdered sugar to it and mix well.
  • If the donuts are fully cool you can carefully hold them upside down and dip them into the blueberry glaze. You can also use a spoon to spoon the topping onto the donuts.
  • Add the any optional toppings right away before the icing sets.

Notes

Tips:
  • Add the fresh blueberries and/or sprinkles before the icing hardens on the donut to make sure it sticks well.
  • Let the donut cool completely before adding the icing.
Storage:
  • Storage: The donuts can be stored in an air-tight container for 4 days. However, the color from the sprinkles may start to rub off on the frosting.
