Add all the ingredients into slow cooker and mix well. Cook on low for 6-8 hours. If you have a programmable slow cooker, set it to cook on low for 7 hours and then switch to warm.
After cooking, give the mixture a good stir as the oats will settle to the bottom. Portion into a bowl and serve.
Optional: top with pecans, maple syrup and almond milk.
