Step 1: Preheat the Air Fryer
Preheat your air fryer to 350°F (175°C) for 5 minutes . This ensures even cooking.
Lightly spray the air fryer basket with cooking spray to prevent sticking.
Step 2: Combine Dry Ingredients
In a large mixing bowl, whisk together the flour, baking powder, baking soda, salt, and granulated sugar until well combined.
Step 3: Mix Wet Ingredients
In a separate bowl, whisk together the milk, applesauce (or melted butter), egg, and vanilla extract until smooth.
Step 4: Combine Wet and Dry Ingredients
Add the wet ingredients to the dry ingredients. Stir gently until just combined—do not overmix. The dough will be soft and slightly sticky.
Step 5: Roll Out the Dough
Lightly flour a clean surface and roll out the dough to about ½-inch thickness .
Use a donut cutter (or two differently sized round cookie cutters) to cut out donut shapes. Re-roll the scraps as needed to use up all the dough.
Step 6: Air Fry the Donuts
Place the donuts in the air fryer basket in a single layer, leaving space between each one for proper airflow. Do not overcrowd the basket.
Cook at 350°F (175°C) for 5–6 minutes , flipping halfway through the cooking time. The donuts are done when they are lightly golden and spring back when touched.
Step 7: Prepare the Cinnamon-Sugar Coating
In a small bowl, mix together the granulated sugar and ground cinnamon.
Brush each warm donut lightly with melted butter, then dip or roll it in the cinnamon-sugar mixture to coat evenly.
Step 8: Serve and Enjoy
Serve the donuts warm for the best flavor and texture. Pair with a cup of coffee, tea, or a glass of milk for a delightful treat.
