Creamy, nutty, and naturally sweet—these Banana Peanut Butter Overnight Oats are everything you love about comfort food, packed into a wholesome, make-ahead breakfast. With only a few pantry staples and five minutes of prep, you’ve got a protein-rich morning meal that feels like a treat!
A Perfect Pair for Your Morning Routine
Banana and peanut butter are one of those iconic duos that just work—like cozy socks and rainy mornings or a good book and a quiet corner. When you pair them with hearty oats and let everything soak overnight, magic happens.
These Banana Peanut Butter Overnight Oats are not only delicious, but also nourishing and filling. They’re packed with fiber, protein, and healthy fats to keep you full for hours.
The banana adds natural sweetness (so no refined sugar needed), and the peanut butter gives it that rich, nutty creaminess we all love.
I’ve been making these on repeat for years, especially when mornings are busy. They’re perfect for grab-and-go breakfasts, school lunch boxes, or even post-workout fuel.
Plus, you can customize them endlessly—add a scoop of protein powder, swirl in a little cocoa powder for a chocolatey twist, or top with granola and fresh fruit. It’s the kind of breakfast that makes you excited to get out of bed.
What You’ll Need
- 1/2 cup rolled oats
- 1/2 cup unsweetened almond milk (or milk of choice)
- 1/2 ripe banana, mashed
- 1 tablespoon peanut butter (natural, creamy or chunky)
- 1/2 teaspoon cinnamon
- 1 teaspoon maple syrup (optional, depending on your banana’s ripeness)
- 1 tablespoon chia seeds (optional, for added thickness and fiber)
- 1/4 teaspoon vanilla extract
- Pinch of sea salt
Optional Toppings:
- Sliced banana
- Drizzle of peanut butter
- Chopped peanuts or granola
- A few mini chocolate chips or cacao nibs
- Greek yogurt or coconut yogurt
Pro Tips
- Use a very ripe banana – The riper the banana, the sweeter your oats will be, and the less added sweetener you’ll need.
- Mix peanut butter thoroughly – Stir it in well to distribute the nutty flavor evenly throughout the oats.
- Make it thicker or thinner – For thicker oats, use less milk or add chia seeds. For a looser texture, stir in more milk before serving.
- Add protein – Mix in a scoop of vanilla or peanut butter protein powder to keep you full longer.
- Don’t skip the salt – A tiny pinch enhances the peanut butter flavor and balances sweetness.
Tools You’ll Need
- Mason jar or airtight container
- Measuring spoons and cups
- Small bowl and fork (for mashing banana)
- Mixing spoon or spatula
- Refrigerator space for overnight chilling
Substitutions and Variations
- No peanut butter? Use almond butter, sunflower seed butter, or tahini.
- Dairy-free? Stick with almond, oat, soy, or coconut milk.
- No banana? Use unsweetened applesauce or mashed cooked sweet potato.
- Want more texture? Add chopped peanuts, flax seeds, or shredded coconut.
- Make it chocolatey: Stir in 1 teaspoon cocoa powder or top with chocolate chips.
Make-Ahead Tips
These overnight oats are made for meal prep. Make a few jars at a time and store in the fridge for up to 5 days.
For best texture, stir the mixture after the first hour of chilling to help distribute the chia seeds and prevent clumps. Store toppings separately and add them just before eating to keep everything fresh and crisp.
How to Make Banana Peanut Butter Overnight Oats
1. Mash the Banana
In a small bowl, mash half of a ripe banana with a fork until mostly smooth.
2. Combine All Ingredients
Add mashed banana, oats, almond milk, peanut butter, cinnamon, maple syrup (if using), chia seeds, vanilla, and salt to a mason jar or container. Stir well until completely mixed.
3. Chill Overnight
Seal the jar with a lid and place in the refrigerator for at least 4 hours or overnight.
4. Stir and Top
In the morning, give the oats a good stir. Add sliced banana, a drizzle of peanut butter, and any other toppings you love.
Leftovers and Storage
Store your overnight oats in a sealed jar in the fridge for up to 5 days. They’ll continue to thicken over time, so just stir in a splash of milk before serving if needed.
Add toppings like fruit, granola, or nuts just before eating to keep them fresh and crunchy
