Add all ingredients, stir, cover and cook on LOW for 7 hours. (If you double the recipe, add an hour of cooking time.)

It is helpful to coat the inside of the slow cooker with organic cooking spray or wipe down with a little oil or butter to keep the oats from sticking at the bottom. Also opening the lid once or twice during cooking to stir helps, making sure to reincorporate any oats from the bottom of the slow cooker -- the benefit is letting the smell of warm apples and cinnamon waft out of the slow cooker!

Store any leftovers in the refrigerator. To reheat, spoon a serving of oatmeal into a microwave safe bowl. Add 1/3 cup of milk and heat on HIGH for 1 minute. Stir and heat for another minute or until hot.
