Ingredients
  

The Filling: Soft, Spiced Apples

  • 3 cups chopped apples Gala is my go-to
  • 1 tablespoon pure maple syrup natural sweetness with depth
  • 2 teaspoons lemon juice helps brighten the flavor and balance sweetness
  • 1/2 teaspoon cinnamon classic warm spice for fall desserts
  • 1 tablespoon almond flour helps thicken the apple juices slightly

The Topping: Crunchy & Golden

  • 1/3 cup quick oats make sure they’re certified gluten-free
  • 1/4 cup brown sugar adds caramel flavor and crunch
  • 2 tablespoons light butter, melted or use coconut oil or vegan butter
  • 2 tablespoons almond flour adds a nutty, rich base for the crumble

Instructions
 

  • Chop the apples into small 1/2-inch pieces and add them to a mixing bowl. Toss with the maple syrup, lemon juice, almond flour, and cinnamon until the apples are evenly coated.
  • In a separate bowl, stir together the brown sugar, quick oats, and almond flour. Drizzle in the melted butter and mix until the topping looks like slightly damp sand, adding a little extra butter if it seems too dry or a sprinkle of almond flour if it feels wet and sticky.
  • Scoop the apple mixture into a shallow air fryer-safe baking dish, spreading it into an even layer no more than about 1 1/2 to 2 inches deep. Sprinkle the crumble topping evenly over the apples without pressing it down so it can crisp properly.
  • Place the dish in the air fryer and cook at 350°F for about 20 minutes, without preheating, until the topping is golden brown and the edges are bubbling. Check occasionally and tent loosely with foil if the top browns too quickly.
  • Carefully remove the dish from the air fryer and let the crisp cool for at least 5 minutes to allow the filling to thicken and the topping to firm up. Serve warm, optionally topped with non-dairy vanilla ice cream or coconut whipped cream.

Notes

  • Choose the right apples:
    Use sweet, tender varieties like Gala, Honeycrisp, or Fuji — they soften quickly and caramelize beautifully in the shorter air fryer cook time.
  • Avoid tough apples:
    Granny Smith tends to stay too firm unless sliced very thin, so it’s not ideal here.
  • Use almond flour wisely:
    • A small amount in the filling gently thickens the apple juices without gluten or cornstarch.
    • Adding almond flour to the topping creates richness, structure, and a golden crisp without turning cakey.
  • Pick certified gluten-free oats:
    Always choose certified GF oats to avoid cross-contamination; Bob’s Red Mill gluten-free quick oats work great.
  • Keep the peels for extra fiber:
    Leave the apple peels on if you like — just chop the apples into ½-inch pieces so they soften fully in the air fryer.
  • Swap the fruit if you want:
    This recipe also works with:
    • Firm pears
    • Well-drained frozen peaches
      If the fruit is naturally very sweet, slightly reduce the maple syrup and adjust warming spices like nutmeg or cardamom to taste.
  • Add crunch if you love texture:
    Mix a handful of chopped walnuts or pecans into the crumble topping.
  • Serve it just warm:
    Let the crisp cool briefly so the filling thickens and the topping stays crunchy. Serve warm with non-dairy vanilla ice cream or coconut whipped cream for extra yum.
