Dice the apple into small bite sized pieces.
Heat coconut oil over medium high heat in a skillet
Add apples, water, 2 teaspoon cinnamon, 1 tablespoon of maple syrup, a dash of sea salt and vanilla.
Stir constantly to coat and heat apples until soft.
Remove from heat and set aside.
In a medium bowl, combine oats, milk, chia seeds, flax, 1 teaspoon cinnamon, walnuts and 1 tablespoon of maple syrup, and a dash of sea salt.
Stir to combine.
Add in apples and stir. (you can add ⅔ of the apples and use the rest as individual topping as well!)
Divide into three individual mason jars or into one large container that can be sealed shut.
Let chill in the refrigerator for at least 6 hours to overnight.
After taking them out of the fridge give your overnight oats one final stir to ensure all that chewy, crunchy, mushy goodness is well-combined and you’ve got all those great textures in each bite.
Add a bit more milk before serving if the oats seem a bit dry.
Top with reserved cooked apples.
Eat hot or cold.
