These Homemade Mini Powdered Donuts are light and fluffy inside with a sweet coating of powdered sugar on the outside. They're made in about 30 minutes with just 12 simple ingredients!
Preheat oven to 350 degrees F. Spray 2 mini donut pans (for 24 donuts total) with nonstick spray.
In a large bowl, add egg, sour cream, milk, vegetable oil, and vanilla extract. Whisk to combine.
Add flour, sugar, baking powder, cinnamon, nutmeg, and salt. Use a rubber spatula to fold the dry ingredients into the wet ingredients until fully combined.
Spoon mixture into a zip top bag or piping bag. Cut off the corner of the bag. Use the bag to pipe the batter into the donut cavities of the pan.
Bake for about 10 to 12 minutes, or until the donuts spring back when touched.
Add powdered sugar to a bowl. Working with one donut at a time, add a donut to the powdered sugar and lightly toss it around to coat on all sides. Repeat with remaining donuts.
Notes
If you're not planning on eating the donuts right away, don't coat them all in the powdered sugar. Because of the moisture in the donuts, the powdered sugar gets absorbed if left to sit on the donuts too long.Instead, coat the donuts in the powdered sugar just before serving and leave any remaining donuts uncoated until ready to eat.
Don't overfill the donut pans! You want to just fill them ¾ of the way up so they still resemble donuts after they rise.
