Tart apples are spiced to perfection with the right amount of sweetness and topped with a delicious oat crumble topping. These individual apple crumbles come together quickly, and are ready in under 30 minutes!
Make the filling: Add the diced apples to a mixing bowl. Immediately after, squeeze the lemon juice over the apples to prevent the apples from oxidizing. Season the apples with all purpose flour, sugar, cinnamon and nutmeg.
