Method

  1. 1

    Preheat your oven to 375°F (190°C) and lightly grease an 8-inch square ceramic baking dish.

  2. 2

    In a mixing bowl, toss the sliced gala apples with ground cinnamon, ground nutmeg, and 1 tablespoon of maple syrup.

  3. 3

    Gently fold the frozen blueberries into the spiced apples, then transfer the fruit mixture into the prepared baking dish, leveling the top.

  4. 4

    In a separate bowl, stir together the gluten-free rolled oats, almond flour, and fine salt.

  5. 5

    Pour the melted unsalted butter and the remaining 1 tablespoon of maple syrup over the dry ingredients, stirring thoroughly until clumps of streusel form.

  6. 6

    Scatter the oat streusel evenly over the fruit layer, making sure the edges and center are well covered.

  7. 7

    Bake at 375°F for 26 to 28 minutes until the blueberry and apple juices are bubbling vigorously around the sides and the oat topping turns fragrant and deep golden brown.

  8. 8

    Remove from the oven and allow to rest for 5 minutes before scooping into bowls.

Tip

Slice the apples thinly to ensure they turn tender during the fast baking time. Leftovers keep well covered in the refrigerator for up to 4 days and re-crisp nicely in a 350°F toaster oven.
