In a large bowl, whisk flour, sugar, baking powder, salt, and cinnamon. In another bowl, whisk milk, melted butter, egg, and vanilla.
Add wet to dry, stirring until just combined. Gently fold in diced apples (and raisins or walnuts if using).
Shape the Fritters:
Scoop ¼-cup mounds of batter onto a parchment-lined air fryer basket, spacing them out (they’ll spread a bit).
Air Fry:
Air fry at 375°F for 8–10 minutes, flipping halfway, until golden and cooked through.
Make the Glaze:
Whisk together powdered sugar, milk, and vanilla until smooth.
Finish:
Dip warm fritters in the glaze or drizzle it over the top. Let the glaze set for a few minutes, then enjoy.
Notes
Tips & Notes:Swap apples for pears if you want a twist.Fritters are best the day they’re made, but can be reheated in the air fryer for 1–2 minutes.Add a sprinkle of cinnamon sugar on top for even more bakery energy.
