two glasses of peanut butter banana overnight oats with banana slices and peanut butter on top and gold spoons in them.

Creamy peanut butter banana overnight oats are the perfect healthy make-ahead breakfast to grab and go on busy mornings. Naturally high in protein and made with no added sugar, this oatmeal will keep you fueled for hours! (gluten-free)


  • 1 medium very ripe banana
  • 1/2 cup plain Greek yogurt
  • 1 1/4 cups milk
  • 2 tbsp natural peanut butter
  • 1 cup rolled oats
  • 1 tbsp chia seeds
  • 1/2 tsp ground cinnamon


  1. In a large jar or other container with a lid (I use a quart size jar), mash the banana.
  2. Stir in yogurt, milk and peanut butter until smooth. 
  3. Stir in oats, chia seeds and cinnamon. 
  4. Cover and refrigerate overnight, or for at least 6 hours. If you'd like, you can portion your oatmeal out into 2 or 3 jars before refrigerating.
  5. In the morning, give it all a stir and enjoy!
  6. If you'd like to warm it up, heat individual portions for 30-60 seconds in a microwave-safe dish.


  • For vegan, use your favorite non-dairy milk and yogurt. Look for high-protein versions to keep the protein content in the overall recipe high.
  • You can also use other nut butters, such as almond butter or mixed nut butter.
  • If you want the oatmeal to be sweeter, you can use vanilla yogurt, or add about 1 tbsp of honey or maple syrup with the yogurt and milk.
  • If you don't like the texture of chia seeds, you can sub in ground flaxseed or just leave them out.
  • Feel free to add any mix-ins, like chocolate chips or walnuts.
