In a large mixing bowl, whisk together the all-purpose flour, packed brown sugar, ground ginger, ground cinnamon, ground nutmeg, baking soda, baking powder, and salt until well combined.
In a separate bowl, mix the unsweetened applesauce, beaten egg, molasses, and vanilla extract until smooth and well-blended.
Gradually pour the wet mixture into the dry ingredients, gently stirring with a spatula until just combined, being careful not to overmix.
Preheat your air fryer to 350°F (175°C) for about 5 minutes.
Lightly spray your donut mold with cooking spray to ensure easy release after cooking.
Carefully spoon the gingerbread batter into the donut mold, filling each cavity about two-thirds full.
Place the filled donut mold into the air fryer basket and cook for 5-7 minutes, or until golden brown and a toothpick inserted into the center comes out clean.
Allow the donuts to cool in the mold for a few minutes before transferring them to a wire rack to cool completely.
Once cooled, dust with powdered sugar or dip in a simple glaze made from powdered sugar mixed with a splash of water for extra sweetness.
Notes
Serve the donuts on a festive platter, garnished with a sprinkle of cinnamon or festive sprinkles.
