Overnight oats are the perfect make-ahead breakfast, which is exactly why I lean on them. I get home from the gym with a full day of work ahead and no time to cook, so I prep a jar the night before, and it's waiting in the fridge when I walk in. I rotate them weekly with my high-protein overnight oats.
I've made this recipe dozens of times, and the biggest thing I learned was how to keep it sweet without adding sugar. I didn't want to use maple syrup or honey as most recipes do, so I leaned on a really ripe, spotty banana instead. It does all the sweetening on its own and makes them taste like my classic oat flour banana bread.
These are in steady rotation, but I switch them up, too. My cinnamon overnight oats are the cozy, warm-spice version, and my banana chia pudding hits the same flavors with a thicker, spoonable texture.

- 5-minute prep: Stir everything in one jar at night, and it's ready by morning. No cooking, no blender.
- Balanced and filling: Around 375 calories with 14g of protein and 11g of fiber to keep you full for hours.
- Meal-prep friendly: Make a few jars at once for grab-and-go breakfasts all week.

Are peanut butter banana overnight oats healthy?
Yes. These are a balanced, filling breakfast with no added sugar, around 375 calories, 14g of protein, and 11g of fiber per serving. Here's what makes them nutritious:
- Oats: Add fiber and complex carbs that help keep you full.
- Chia seeds: Bring fiber and omega-3s.
- Banana: Adds natural sweetness and potassium, so you skip the added sugar.
- Peanut butter: Adds protein and healthy fats.
The toppings and ingredients you choose make a difference, so I use natural peanut butter with no added sugar and unsweetened milk.
⭐️⭐️⭐️⭐️⭐️
Overnight oats are the best "on the go" breakfast. I bring these to work many mornings, and this is my favorite recipe to use! Peanut butter + banana combo is the BEST!

Ingredients You'll Need
You only need five simple ingredients to make these peanut butter banana overnight oats. Here's what each one does:
- Rolled oats: The base. Old-fashioned rolled oats soften perfectly overnight and hold their texture. Skip steel-cut (too chewy) and quick oats (too mushy).
- Banana: A ripe, spotty banana does all the sweetening, so there's no added sugar. It's also what gives them that banana bread flavor.
- Peanut butter: Use natural peanut butter with no added sugar. It adds protein, healthy fats, and that classic PB-and-banana flavor. Creamy or crunchy, both work.
- Milk: Any milk works. I use unsweetened almond milk, but dairy or soy will add more protein.
- Chia seeds: They thicken everything overnight, so the oats turn creamy instead of watery, plus they add fiber. They do the same job in my oat milk chia pudding.

Substitutions & Variations
- Make it dairy-free: Use almond, oat, or cashew milk instead of dairy.
- Make it nut-free: Swap the peanut butter for sunflower seed butter.
- Make it gluten-free: Use certified gluten-free rolled oats.
- Peanut butter swap: Almond butter or cashew butter both work in place of peanut butter.
- Rolled oats: Quick oats work but turn out softer. Don't use steel-cut; they won't soften enough overnight.
- Chia seeds: Swap in ground flax or hemp hearts, or leave them out and use a little less milk so the oats still thicken.
- Chocolate version: Stir in a teaspoon of cocoa powder, a scoop of chocolate protein powder, or a few chocolate chips.
- Higher protein: Add a scoop of protein powder with an extra splash of milk. For a bigger boost, try my high-protein overnight oats.
- Extra toppings: Add some healthy granola, chopped peanuts, or fresh fruit just before eating.
How to Make Peanut Butter Banana Overnight Oats (Step-by-Step)
These come together in three steps and take about five minutes. Here's how I make them:
- Step 1: Mash and mix. Mash the banana in the jar, then whisk in the milk and peanut butter until smooth.
- Step 2: Add the oats and chia. Mix until the oats are fully coated and submerged in the milk.
- Step 3: Chill and stir. Seal the jar and refrigerate at least 4 hours or overnight. Stir before eating and add a splash of milk if it's too thick.
Tips for the creamiest overnight oats
- Stick to a 1:1 oats-to-milk ratio: I use ½ cup rolled oats to ½ cup milk. It's the ratio I landed on after my early jars kept coming out soupy. Too much liquid and they never set up; too little and they turn dense.
- Use rolled oats, not quick or steel-cut: Rolled oats soak up the milk and soften evenly overnight. Steel-cut oats stay chewy because they need heat to break down, and quick oats go mushy since they're already partly cooked.
- Don't skip the chia seeds: One tablespoon is what thickens the oats into a creamy, pudding-like texture. They absorb liquid and gel as they sit, so leave them out, and the oats turn thin.
- Mash the banana fully before adding anything else: A spotty, overripe banana mashes smoothly and folds right in. Under-ripe banana leaves will not sweeten the same way.
- Stir, then stir again after 5 minutes: The chia and oats clump on the first mix. A second stir, a few minutes later, breaks them up so they soak evenly instead of settling at the bottom.
- Add a splash of milk in the morning: Overnight oats thicken as they sit. A spoonful of milk and a quick stir loosens them back to that just-made creamy texture.
How to Store and Meal Prep
- In the fridge: Store in a sealed jar or airtight container for up to 3 to 4 days. They're creamiest in the first 2 days.
- Make a batch: This is what I do every Sunday. Mix a few jars at once so breakfast is ready to grab all week.
- Add toppings fresh: Stir in the oats, banana, and chia ahead, but wait to add sliced banana, granola, or extra peanut butter until you're ready to eat so they don't go soggy.
- Freezing: I don't recommend it. The texture turns watery and grainy once thawed, so these are best made fresh and kept in the fridge.
Peanut Butter Banana Overnight Oats FAQs
Yes. Stir in a couple of tablespoons of Greek yogurt for a thicker, creamier texture and extra protein. This recipe skips it to stay dairy-free, but it's an easy add.
Yes, but they'll be thinner since chia is what thickens them. Use a little less milk, or let them sit longer to firm up.
Usually too much milk. Stick to a 1:1 oats-to-milk ratio and make sure you're using rolled oats, which absorb more liquid than quick oats.
The banana sweetens these and gives the banana bread flavor, so I don't recommend leaving it out. Without it, you'd need to add a sweetener like maple syrup or honey, and lose flavor. Try my cinnamon overnight oats for a banana-free recipe!
Add a scoop of protein powder with an extra splash of milk, or stir in Greek yogurt. For a 40-gram version, try my protein powder overnight oats.
Yes. Crunchy adds texture and creamy makes them smoother, so use whichever you prefer.
