INGREDIENTS:
For the donuts: 
- 1 cup flour
- 1/3 cup white sugar
- 1 teaspoon baking powder
- 1/8 teaspoon ground nutmeg
- 1/8 teaspoon ground cinnamon
- 1/2 teaspoon salt
- 1/3 cup buttermilk (or regular milk with a teaspoon of white vinegar added)
- 1 egg, beaten
- 1 teaspoon vanilla
- 1 1/2 teaspoons oil
- 1/2 cup fresh or frozen blueberries
For the glaze:
- 1 1/2 cups powdered sugar
- 1/4 cup milk or water
- 1 teaspoon vanilla
DIRECTIONS:
- Preheat the oven to 325 degrees. Lightly grease a donut pan.
- In a large bowl, whisk together the flour, sugar, baking powder, nutmeg, cinnamon, and salt.
- In a small bowl, stir together the butter milk, egg, vanilla and oil.
- Add the wet ingredients to the dry and stir with a wooden spoon until fully incorporated.
- Fold in the blueberries, trying not to break them up too much.
- Fill the donut pan and bake for 10-12 minutes or until lightly browned and cooked through.
- Remove from the oven and cool in the pan for a few minutes before transferring to a wire rack.
- Sift the powdered sugar (I usually just whisk it really good to break up any clumps) and place in a small bowl.
- Stir in the milk and vanilla until fully combined.
- When the donuts are cool, dunk the tops of the donuts in the glaze.
- Return the donuts to the wire rack for 5 minutes to let the glaze set.
