Dry ingredients: Add the oats, chia seeds, hemp seeds (if using), and a pinch of salt to a jar.
Wet ingredients: Pour in the milk, vanilla extract (if using), and maple syrup (if using). Stir in the yogurt. Close the jar with a lid and place it in the fridge to set overnight or at least 4 hours.
In the morning, add the toppings of your choice.
Notes
Storage: overnight oats will last 4-5 days in the fridge for up to 5 days, which is ideal for meal prepping. The nutritional information is for overnight oats without hemp seeds or any sweetener.
