4 medium apples, peeled, cored, and sliced
0.5 cup gluten-free oats Shop
0.5 cup gluten-free all-purpose flour blend Shop
0.5 cup packed brown sugar or coconut sugar Shop
0.5 cup cold butter or vegan butter, cut into cubes
1 tsp ground cinnamon Shop
0.25 tsp ground nutmeg Shop
1 tbsp lemon juice

Instructions

1 Preheat your oven to 375°F (190°C) and lightly grease an 8x8 inch baking dish. In a large bowl, toss the sliced apples with lemon juice, ground cinnamon, and ground nutmeg until evenly coated, ensuring each slice is fragrant with spice. Set aside.
2 In a separate medium bowl, combine the gluten-free oats, gluten-free all-purpose flour blend, and packed brown sugar. Whisk these dry ingredients together until well incorporated, creating a base for your crisp topping.
3 Add the cold butter cubes to the oat mixture. Using your fingertips or a pastry blender, cut the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized pieces. This should take about 3-5 minutes, and the texture should feel slightly damp and crumbly.
4 Arrange the spiced apple slices evenly in the prepared baking dish. Sprinkle the prepared oat topping generously and evenly over the apples, ensuring complete coverage for a delightful crunch. This step should take about 1-2 minutes.
5 Bake for 30-35 minutes, or until the topping is golden brown and crisp, and the apples are tender and bubbling around the edges. The aroma of baked apples and cinnamon will fill your kitchen. Let the crisp cool for at least 10-15 minutes before serving to allow it to set properly.

Tips & Notes

For the streusel, buy oats with a gluten-free label, ideally certified. Unlabeled oats are commonly cross-contacted with other grains before they reach the store.
Firm apples such as Granny Smith, Honeycrisp or Braeburn hold their shape. Softer apples like McIntosh collapse into sauce during a 30-minute bake.
Chill the finished topping for 10 minutes before you sprinkle it on. Cold butter makes larger, crisper clumps.
