- 1 cup all-purpose flour
- ½ cup white sugar
- ¼ cup cold salted butter, cubed
- ½ teaspoon ground cinnamon
- ½ teaspoon baking powder
- ¼ teaspoon ground nutmeg
- cooking spray
- 2 ½ cups peeled, cored, and diced apples
- Preheat an air fryer to 350 degrees F (175 degrees C).
- Step 2Place flour, sugar, and butter in a medium bowl. Use your hands to mix until crumbly. Stir in cinnamon, baking powder, and nutmeg.
- Step 3Spray two 4 1/2-inch ramekins with nonstick cooking spray. Add some crumble to the bottom of ramekins; top with some apples. Repeat 2 more times, ending with mounded crumble on top.
- Step 4Cover the ramekins with large pieces of foil, tucking ends underneath to prevent it from flying off. Air fry until apples are tender, 16 to 20 minutes. Remove foil and air fry until crumble is golden brown, 2 to 4 more minutes.
