Why You'll Love Peanut Butter Overnight Oats
Who doesn't love a nutritious breakfast with a 5-minute prep? This recipe keeps things simple yet creates a craveable meal. Rolled oats soften as they chill overnight, giving them a thick, creamy consistency. Mashed banana helps everything blend smoothly and adds natural sweetness, so the added sweetener in this recipe is minimal.
Peanut butter and banana are a classic combination that most people already love, which works especially well in overnight oats. Chia seeds help thicken the mixture as the oats soak overnight, adding fiber and protein to this creamy, dreamy meal-prep breakfast.
Ingredients You’ll Need
- Banana – Ripe or overripe bananas add natural sweetness and help create a smooth, creamy texture when mashed.
- Peanut butter – Brings richness and classic peanut butter and banana flavor to overnight oats.
- Rolled oats – Old-fashioned rolled oats soften as they soak yet hold their shape for a sturdy, spoonable texture.
- Chia seeds – These add core nutrients and also absorb liquid as the oats soak overnight, helping thicken the mixture.
- Vanilla, cinnamon, and salt – These bring all the flavors together and provide depth and balance.
- Milk – Any milk or plant-based milk can be used. It helps control how creamy the oats turn out.

How To Make Overnight Oats With Peanut Butter And Banana
Mash the banana with the peanut butter, rolled oats, chia seeds, vanilla, cinnamon, maple syrup or honey, and salt until smooth and creamy. Add the milk and stir until fully combined. Keep the mixture in the bowl or portion it into jars or containers. Refrigerate overnight until the oats are set. By morning, they’ll be thick, creamy, and ready to eat with your favorite toppings.

Recipe Tips
- Use ripe or overripe bananas. A ripe banana works well, but an overripe banana adds even more natural sweetness and mashes easily into the oats.
- Peanut butter type. I prefer natural, creamy peanut butter, but if you’re using a sweetened variety, consider skipping the maple syrup so your oats aren’t too sweet.
- Use any milk you like. I love soy milk when keeping this plant-based, but dairy or non-dairy milk at any fat level works well in this recipe.
- Sweetness is intentionally mild. This recipe relies on the combination of natural banana sweetness and maple syrup (or your sweetener of choice), so taste and adjust after chilling if needed.
- Toppings and add-ins are flexible. Shredded coconut, fresh or frozen berries, or chocolate chips can be stirred in before chilling or added on top just before serving. Add a scoop of nonfat yogurt for a protein boost.
- Expect a thicker texture after chilling. These oats set up creamy, but they also could use a quick stir before serving to distribute the ingredients, if needed. Add a splash of milk if you want them looser.
Toppings & Serving
Toppings are optional and best added right before serving. A dollop of peanut butter, banana slices, and a sprinkle of dark chocolate chips are a favorite combo. Feel free to add homemade granola and a handful of shredded coconut! When serving, give the oats a quick stir before eating, and add a splash of milk to thin them out if needed. You can heat them in the microwave on a gentle setting if you prefer them warm.

Make-Ahead & Storage
These peanut butter overnight oats are ideal for meal prep and grab-and-go for busy mornings. Once mixed, they can be refrigerated overnight for up to 5 days. Store them in glass jars or any containers of choice with fitted lids.

I am a big fan of having oatmeal for breakfast... and you've just made regular morning oats EASIER and BETTER! I love that this can come together in just 5 minutes and the no cook part is also quite nice! 🙂 Thank you for sharing this breakfast gem!
Traci says
That makes me so happy to hear! Easy, no-cook breakfasts are exactly what I was going for. Thanks for taking the time to leave a comment 🙂
JB says
Made these last night. Loving them this morning! Perfect amount of peanut butter and banana. Thank you for always making my life easier.
Rosalee says
Will this recipe be possible without bananas?
They send my blood sugar into a dump shortly after eating them
I suffer HYPOglycemia so I am careful about what fruit I eat and
bananas are on top of the list (grapes comes next)
Thank you
Traci says
Sure, you can absolutely make this without banana. One of the nice things about this oats recipe is how flexible they are. If you leave the banana out, you may want to slightly reduce the milk to keep the oats thick and creamy. Thanks for sharing your experience, and I’m glad you’re paying attention to what works best for you. Enjoy!
