Preheat oven to 350° Fahrenheit.
Add the chopped apples, coconut sugar, and cinnamon to a small ramekin and stir until the apples are evenly coated in sugar. Set that aside then make the crumble.
Mix together the rolled oats, almond flour, coconut sugar, and melted butter or coconut oil in a small bowl until a crumby mixture forms. Sprinkle the crumble evenly over the top of the apples.
Bake the apple crumble for 25-30 minutes, or until the apples are very soft. Let the apple crumble cool slightly before topping with ice cream, yogurt, or whipped cream.
