How to Make Air Fryer Apple Cinnamon Crumble Bars
- Prepare the crumble mixture
In a bowl, mix flour, granulated sugar, brown sugar, salt, and cinnamon. Cut in cold butter until crumbly. Stir in vanilla. Reserve ¾ cup for topping. - Press the crust
Press remaining crumble mixture firmly into a parchment-lined air fryer-safe pan (7–8 inches). - Make the apple filling
Toss diced apples with brown sugar, cinnamon, cornstarch, and lemon juice. - Assemble
Spread apple mixture evenly over crust. Sprinkle reserved crumble on top. - Air fry
Preheat air fryer to 320°F. Cook for 18–22 minutes until topping is golden and apples are tender. Check at 18 minutes to prevent over-browning. - Cool and slice
Let bars cool completely before slicing for clean cuts. Drizzle with glaze if desired.
