In a jar or bowl, combine the oats, milk, yogurt, maple syrup, chia seeds, vanilla cinnamon, and sea salt.
Stir well to make sure all the ingredients are combined. Cover with a lid and place in the refrigerator overnight.
In the morning, remove from the refrigerator and stir. If they are too thick, you can add a splash of milk. Top with desired toppings and mix-ins (see the post for ideas). Eat and enjoy!
