Preheat your oven to 350°F (175°C) and grease your donut pan.
In a large bowl, whisk together the dry ingredients until no lumps remain.
In a separate bowl, mix the wet ingredients until well combined.
Pour the wet mixture into the dry ingredients and stir until just combined.
Fill each donut mold about two-thirds full with the batter.
Bake for 10 to 12 minutes, checking for doneness with a toothpick.
Let the donuts cool for about 5 minutes before transferring to a wire rack.
Optional: Glaze with powdered sugar mixed with milk.
