I can never get enough peanut butter. I eat it daily in some form, and it doesn’t matter to me if it’s in a savory recipe like my Thai pasta, or a sweet recipe like my flourless peanut butter cookies.

Of course it’s wonderful spread on toast or waffles, and one day I stirred it into my blueberry overnight oats and had an a-ha moment.

That led me to create these Peanut Butter Overnight Oats, and it turned into one of my favorite breakfasts.

Peanut butter makes these creamy oats so much more satisfying with the addition of healthy fat and protein, and they couldn’t be easier to make.

The fun part is choosing how to top them off. Bananas, blueberries, chocolate chips….there are so many tasty options. 🙂

Peanut butter overnight oats ingredients

Ingredient notes

  • Old fashioned rolled oats.  Rolled oats add a nice, hearty texture, and I don’t recommend substituting them with quick oats. See my overnight steel cut oats recipe if you prefer to use steel cut oats.
  • Peanut butter. Sub the peanut butter with your favorite nut butter or sun butter.
  • Chia seeds.  Chia seeds help thicken overnight oats, but if you don’t have any on hand, you may omit them and reduce the quantity of milk by 1/2 cup.
  • Unsweetened almond milk. Sub with your favorite dairy or non-dairy milk.
  • Maple syrup. Sub with your favorite sweetener. 
  • Optional ingredients: Banana and chocolate chips are optional ingredients, and can be omitted with your favorite toppings or add-ins.
