Preheat oven to 375F. Peel and chop the apple into mini pieces. Add sugar and cinnamon to the apples. Firmly press down the apples to the bottom of the ramekin. Bake the crumble by combining the flour, oats, sugar and melted butter (the recipe states 'oil' but 'melted butter' is listed as an ingredient). Place the crumble on top of the apples. Bake for 15 min. Top with vanilla ice cream or yogurt. Enjoy!
