To make the filling: Peel, core and slice your apples.
In a medium bowl, combine apples, cinnamon and lemon juice. Stir together until apples are coated evenly.
To make topping: in a separate bowl, whisk together almond flour, oats, salt, cinnamon, chopped pecans and coconut sugar.
Use a fork or fingers to mix butter until topping has a crumbly consistency.
Arrange apples into a 9-inch pie dish or baking dish. Cover with crumble topping.
Bake for 30 to 35 minutes, or until top is golden brown. Remove from oven and cool for 5 to 10 minutes. Apple crisp is best served immediately. Store leftovers covered in refrigerator up to 4 days.
