• Peel and chop the apple into ¼-inch dice. You want about 1 heaped cup of chopped apples.
• Preheat the air fryer to 350°F for 7 minutes. While it preheats, prepare the fritter batter.

  👉 Letting the air fryer run empty helps jump-start the cooking process and gives the fritters a better rise and crispier top.
• Whisk the flour, sugar, cinnamon, baking powder, baking soda and salt in a small bowl.
• In a large bowl, whisk together the egg white (or yolk), yogurt (or sour cream or buttermilk), and melted butter until well combined.
• Gently stir in the flour mixture until just combined, then fold in the chopped apples until evenly distributed.
• Open the air fryer — it’s okay if the 7-minute preheat hasn’t finished. Generously grease the air fryer basket with cooking spray. Using two spoons, drop about ¼ cup of batter per fritter into the basket, spacing them evenly apart.
• Gently flatten the tops with the back of a spoon to shape them into fritters.

  👉 For a crispier crust, lightly spray the tops with non-stick cooking spray.
• Air fry at 340°F for 10 to 12 minutes, or until the tops are deep golden brown. Let the fritters cool for at least a minute before gently removing them from the basket.

Glaze

• In a small bowl, whisk together all glaze ingredients until smooth. Adjust the water as needed — the glaze should be pourable but slightly thick.
• Place the fritters on a wire rack set over a plate or baking sheet. Using a spoon, evenly drizzle the glaze over the tops of the fritters. Let it sit for a few minutes for the glaze to set.
