Ingredients Equipment Method Notes

Ingredients
  

  • 1 medium apple about 6 ounces (170 g), cored and diced
  • 1 teaspoon lemon juice
  • 2 teaspoons brown sugar divided
  • 1/4 teaspoon ground cinnamon
  • 1 tablespoon old-fashioned rolled oats
  • 1 tablespoon all-purpose flour
  • 1 teaspoon cold unsalted butter cut into small pieces
  • Pinch of salt

Equipment

  • 3-quart or larger air fryer
  • heat-safe 8-ounce ramekin
  • small bowl
  • knife and cutting board
  • measuring spoons
  • oven mitt or heat-safe tongs

Method
 

  1. Wash, core, and dice the apple into roughly 1/2-inch pieces.
  2. Toss the apple in an 8-ounce heat-safe ramekin with lemon juice, 1 teaspoon brown sugar, and cinnamon.
  3. Mix oats, flour, remaining brown sugar, and salt in a small bowl. Rub in cold butter until small crumbs form; scatter over the apple without packing down.
  4. Preheat the air fryer to 325°F (163°C) if recommended by its manufacturer. Place the ramekin flat in the basket with room for airflow.
  5. Air fry at 325°F (163°C) for an estimated 18 to 24 minutes; check after 15 minutes. Cook until the apple is tender, juices bubble, and the topping is dry and golden with no raw-looking flour.
  6. Carefully remove the hot ramekin and rest the crisp for 5 minutes before serving.

Notes

Serves one person. Cooking time and nutrition are estimates, not measurements.
Use only an oven-safe ramekin approved for your air fryer; avoid thermal shock.
Do not taste the raw flour-containing topping. If the topping browns before the apple softens, reduce heat slightly and continue checking.
