Spray your slow cooker bowl with coconut oil thoroughly. Very important because this oatmeal will stick...bad...if not coated.
Add all ingredients, besides toppings to your slow cooker – oats, coconut milk, water, apples, honey, coconut oil, cinnamon, and sea salt. Stir to combine.
Cook on LOW for 5-7 hours. Some crockpots take longer and some are pretty fast. Mine was done perfectly at 5 hours, so I allow the crockpot to automatically turn off, and cool for quite awhile before breakfast begins.
Try a test run during the day to see how long your slow cooker takes. If you double the recipe, as I often do...cook time will increase a bit. If desired, add toppings of your choice.
