If you crave a nourishing breakfast but mornings never seem long enough, these overnight oats with banana and peanut butter are your answer. With just a few simple ingredients and no stove required, you wake up to a creamy and satisfying meal already made and ready to go.
My first batch of these oats was a happy accident before an early hike and they kept me energized for hours. Now I make them almost every week during busy seasons.
Ingredients
- Rolled oats: Choose traditional old-fashioned oats for a creamy texture, avoid quick oats as they get mushy
- Milk of choice: Use dairy or plant-based milk based on preference for flavor and creaminess, soy or oat milk adds an extra smooth finish
- Peanut butter: Go for natural peanut butter with a single ingredient for full flavor and balanced nutrition, crunchy or smooth both work well
- Banana: Choose ripe bananas with lots of brown spots for the best sweetness and natural creaminess
- A touch of honey or maple syrup: If you want extra sweetness, pick pure syrup for a clean taste
- Pinch of salt: Brings out the nutty flavor and balances the sweetness
Instructions
- Combine the Dry and Wet Ingredients:
- Add rolled oats and milk to a sturdy jar or container. Stir well so oats are evenly soaked and not clumped together. Let them sit for a minute to start absorbing the liquid.
- Mix in Banana and Peanut Butter:
- Mash half a banana until very smooth and stir it into the oat mixture along with the peanut butter. Add a small drizzle of honey or maple syrup if you like it sweeter.
- Balance and Taste:
- Sprinkle in a small pinch of salt and stir again to fully incorporate. Taste the mixture so you can adjust sweetness or add more banana if desired.
- Seal and Refrigerate:
- Tightly close the jar or container and refrigerate overnight or at least eight hours. During this time the oats soften and absorb all the flavors.
- Morning Toppings:
- In the morning, slice the remaining banana and gently fold in or layer on top. Add a spoonful of peanut butter or a drizzle of extra milk if you prefer it a bit thinner. Finish with a sprinkle of nuts, seeds or a dusting of cinnamon if you like.

My favorite part of this recipe is how the banana almost melts into the oats by morning making every bite naturally sweet and creamy. Every time I prepare it the kitchen smells like comfort and childhood summers.
Storage Tips
Store each serving in its own jar with a tight lid so you can grab and go in the morning. Overnight oats keep their best texture for up to four days so feel free to prep a batch on Sunday night for several quick breakfasts. If the oats seem too thick after a night in the fridge just stir in an extra splash of milk or plant-based drink.
Ingredient Substitutions
Swap almond butter or cashew butter if you have a peanut allergy or want a different flavor profile. For dairy free try oat milk or almond milk which both blend well with the oats. Chopped dried fruit or coconut flakes can take the place of fresh banana if needed.
Serving Suggestions
Top your oats with a sprinkle of chopped roasted nuts or seeds for a little crunch. Sliced strawberries or blueberries add a nice tart contrast to the sweetness of banana. For a fun twist swirl in a spoonful of cocoa powder to make them taste like a peanut butter cup treat.
Cultural Roots
Overnight oats are inspired by bircher muesli a Swiss breakfast favorite from the early 1900s. In France this version with peanut butter and banana puts a modern spin on an old world idea creating a breakfast that feels both classic and contemporary.
Seasonal Adaptations
Add fresh raspberries or strawberries in spring for a burst of tartness. Top with sliced peaches or nectarines for a summer twist. Sprinkle with pumpkin seeds and cinnamon in fall for extra warmth.
Success Stories
Many friends who swore they did not like oatmeal changed their minds after trying this recipe. I have watched kids and adults alike dig in and ask for seconds after the first taste. This one never disappoints anyone who tries it.
Freezer Meal Conversion
If you need to batch prep even further make and portion your oats without the banana then freeze. Thaw overnight in the fridge and add fresh banana and toppings in the morning for the best flavor and texture.

Wake up to a breakfast that's ready when you are, creamy, and utterly satisfying. Let these peanut butter banana oats reinvent your mornings with ease.
