Milk. To get creamy overnight oats you’ll want to use milk. Please don’t use water! Cows milk, almond milk, oat milk, or any diary free milk of choice will work nicely in this recipe.

Peanut butter. You can use creamy or crunchy peanut butter. Make sure you use an all natural kind as processed nut butters have added chemicals and sugars. Give your natural peanut butter a good stir as it may have a layer of oil on top.

Salted peanuts. Feel free to omit the peanuts for another type of nut or seed. Cashews and almonds also work well in this recipe.

Maple syrup. Pure maple syrup works best in this recipe but you can also use honey! Or omit the natural sweeteners all together.
