1-Preheat oven to 350°F (175°C) and lightly grease an 8×8-inch baking dish.

2-In a large bowl, combine all filling ingredients 5 medium-sized apples (peeled, cored, and thinly sliced), 3 tablespoons apple juice or apple cider, 2 tablespoons pure maple syrup, 1 tablespoon cornstarch, ½ teaspoon ground cinnamon, and ½ teaspoon pure vanilla extract mixing well, then transfer to the prepared dish.

3-In a separate bowl, whisk together ⅓ cup almond flour, 1 cup old fashioned oats, ¼ cup finely chopped pecans or walnuts, ¼ teaspoon ground cinnamon, and a pinch of salt.

4-In another bowl, blend 4 tablespoons melted unsalted butter and ¼ cup pure maple syrup, then pour into the dry ingredients and stir until crumbly.

5-Spread the topping evenly over the apple mixture in the dish.

6-Cover with foil (lightly coated with nonstick spray) and bake for 25 minutes. Remove foil and bake for an additional 25 35 minutes, until apples are tender and the topping is golden brown.

7-Once done, cool slightly before serving warm, optionally with yogurt or ice cream.
