Key Ingredients

Just a few pantry staples make the creamiest make-ahead breakfast. Here is what each one brings.
- Rolled Oats: Old fashioned rolled oats soak up the liquid overnight and turn soft, creamy, and spoonable by morning.
- Peanut Butter: The star of the bowl, adding rich, nutty flavor and a boost of protein and staying power.
- Milk: Any milk works, from dairy to almond or oat, to soften the oats into that signature creamy texture.
- Maple Syrup: A touch of natural sweetness that balances the salty peanut butter without refined sugar.
- Banana and Chocolate Syrup: Sliced banana and an optional drizzle of chocolate make every jar taste like a treat.

Variations and Substitutions
These Peanut Butter Overnight Oats are easy to make your own. Here are a few favorite twists.
- Use any milk you like, from dairy to almond, oat, soy, or coconut.
- Swap the peanut butter for almond butter, cashew butter, or sunflower seed butter for a nut-free version.
- Stir in chia seeds or a scoop of protein powder for extra staying power.
- Top with fresh berries, sliced banana, granola, or a drizzle of honey the way we do with our banana nut muffins.
How to Make Peanut Butter Overnight Oats

- Add the milk, peanut butter, maple syrup, and a pinch of sea salt to a mason jar or sealable container. Stir to combine, and do not worry if the peanut butter is not fully incorporated.

- Add the rolled oats to the jar.

- Stir to combine, then press the oats down so they are fully covered in the liquid.

- Seal the jar and refrigerate overnight, or until the oats are softened. When ready to serve, top with more peanut butter, banana slices, and a drizzle of chocolate syrup.
Recipe Tips & Tricks
- Use rolled oats. Old fashioned rolled oats give the best creamy texture; quick oats turn mushy and steel cut stay too firm.
- Press the oats down. Make sure every oat is submerged so they soften evenly overnight.
- Chill at least 4 hours. Overnight is ideal, but a few hours in the fridge will soften them in a pinch.
- Adjust the thickness. Add a splash more milk in the morning if you like your oats looser.
- Add toppings fresh. Stir the oats together, then add banana and chocolate just before eating so they stay fresh.
- Batch it. Make several jars at once for a full week of grab-and-go breakfasts.
Serving Ideas and Suggestions
These Peanut Butter Overnight Oats are a complete breakfast on their own, but they are even better topped with fresh banana, berries, granola, or a sprinkle of mini chocolate chips.
For a bigger spread or a brunch, serve a few jars alongside our French toast or a warm overnight breakfast casserole so everyone has a sweet and savory option.
Since they keep for days, make a batch on Sunday and grab a jar each morning, or pack one for an easy breakfast at work or school.

Peanut Butter Overnight Oats FAQs
Old fashioned rolled oats are the best choice. They soak up the liquid and turn creamy without going mushy. Quick oats break down too much, and steel cut oats stay too chewy unless soaked much longer.
Stored in a sealed jar in the fridge, they keep for up to 4 to 5 days, which makes them perfect for meal prep. Add fresh toppings like banana just before eating so they stay fresh.
Yes. Although they are designed to be eaten cold straight from the fridge, you can microwave them for 30 to 60 seconds if you prefer a warm bowl. Add a splash of milk first to loosen them.
Absolutely. The banana is a topping, not a requirement. Leave it off or swap in berries, apple, diced peaches, or just extra peanut butter and chocolate.
Use a lighter milk, reduce the peanut butter to one tablespoon, cut back on the maple syrup, and skip the chocolate drizzle. Powdered peanut butter is also a great lower-fat swap that keeps the flavor.
No. The whole point of overnight oats is that the oats soften in the fridge with no cooking. Just stir, seal, and chill, and they will be creamy and ready to eat by morning.

Yes, it makes one large serving, but I believe it would make 2 sensible servings so you could cut that in half. This is definitely NOT a low calorie recipe.
