Ingredients
  

For the apple layer

  • 6 medium apples (Honeycrisp, Pink Lady, or Granny Smith), peeled, cored, and sliced thin
  • 2 tablespoons lemon juice
  • 1-2 tablespoons granulated monk fruit erythritol blend (or allulose), to taste
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon nutmeg
  • 1 teaspoon vanilla extract
  • 1 tablespoon arrowroot or cornstarch (optional, for thicker juices)
  • 1 pinch of salt

For the crumble topping

  • 1 cup old-fashioned rolled oats (certified gluten-free if needed)
  • 1/2 cup almond flour (or fine-ground almond meal)
  • 1/4 cup chopped walnuts or pecans (optional but recommended)
  • 1/4 cup unsweetened shredded coconut (optional for texture)
  • 1/3 cup granulated or brown-style monk fruit/erythritol sweetener (or allulose)
  • 1 teaspoon ground cinnamon
  • 1/8 teaspoon salt
  • 5 tablespoons cold unsalted butter, diced (or coconut oil for dairy-free)

To finish (optional)

  • Plain Greek yogurt, sugar-free vanilla yogurt, or a dollop of unsweetened whipped cream

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C) and lightly grease an 8x8-inch or 9x9-inch baking dish.
  • Slice apples evenly, aiming for thin, uniform slices (about 1/4 inch).
  • In a large bowl, toss apples with lemon juice, sweetener, cinnamon, nutmeg, vanilla, starch (if using), and salt. Spread evenly in the baking dish.

Crumble Topping

  • In another bowl, combine oats, almond flour, nuts, coconut, sweetener, cinnamon, and salt.
  • Add cold butter and cut it in with a pastry cutter or your fingertips until sandy with pea-sized bits.

Assembly and Baking

  • Sprinkle the crumble evenly over the apple mixture. Don’t pack it down.
  • Bake for 35-45 minutes until the topping is golden and the apple juices bubble at the edges.
  • If the top browns too fast, tent loosely with foil.

Serving

  • Let it cool for 10-15 minutes to set the juices.
  • Serve warm, optionally with Greek yogurt or sugar-free whipped cream.

Notes

Cool completely before refrigerating. Store for up to 4 days. For best results, keep the topping uncovered until fully cool. Can be frozen for up to 2 months.
