What You’ll Need
- ½ cup rolled oats
- ½ cup unsweetened almond milk (or milk of choice)
- ¼ cup plain Greek yogurt (or plant-based yogurt)
- 1 tablespoon peanut butter
- 1 tablespoon chia seeds
- ½ banana, mashed

- Pinch of sea salt
Optional Toppings:

Pro Tips
- Use ripe bananas – The riper the banana, the sweeter and more flavorful your oats will be.
- Smooth vs. crunchy peanut butter? Use what you love. Crunchy adds texture, smooth gives you a silky consistency.
- Stir well twice – Mix once when assembling and again after 10–15 minutes to prevent clumping.
- Customize sweetness – If your banana is super ripe, you might not need any extra sweetener.
- Want it warm? Just microwave for 30–60 seconds in the morning.
Tools You’ll Need
- Mason jar or airtight container
- Measuring cups and spoons
- Spoon or spatula
- Small bowl for mashing
- Refrigerator
Substitutions and Variations
- Nut-free? Use sunflower seed or oat butter instead of peanut butter.
- Dairy-free? Swap Greek yogurt with coconut or almond-based yogurt.
- Add more protein? Add a scoop of vanilla or peanut butter protein powder.
- No chia seeds? Use ground flaxseeds or skip for a thinner texture.
- Want a chocolatey version? Add 1 tsp cocoa powder or dark chocolate chips.
Make-Ahead Tips
This recipe is perfect for meal prep. You can make up to 4 jars at once and store them in the fridge for up to 5 days. Keep your toppings (like banana slices, nuts, or granola) separate until serving to preserve their texture.
To freeze: store the oat base without toppings in freezer-safe containers. Thaw overnight in the fridge and stir well before enjoying.
How to Make High‑Protein Peanut Butter Banana Overnight Oats
1. Mash the Banana
In a small bowl, mash half a ripe banana with a fork until mostly smooth.

In a mason jar, combine almond milk, Greek yogurt, peanut butter, vanilla, and maple syrup. Stir until smooth and creamy.
3. Add Dry Ingredients

Seal the jar with a lid and refrigerate overnight (or for at least 4 hours) until thickened.

In the morning, stir the oats. Top with banana slices, peanut butter drizzle, granola, or chopped nuts.
Leftovers and Storage
Store in an airtight container in the fridge for up to 5 days. Stir well before eating, and add a splash of milk if the texture is too thick. Add bananas and crunchy toppings just before serving.
Freezer tip: Freeze the oat base (without toppings) for up to 1 month. Thaw overnight in the fridge and stir before serving.
Recipe FAQ
1. Can I use quick oats instead of rolled oats?
Yes, quick oats will work and result in a softer texture. Avoid steel-cut oats unless you cook them first.
2. Can I leave out the yogurt?
Yes, you can use an extra 2–3 tablespoons of milk to maintain the right consistency without yogurt.
3. Is this recipe good for kids?
Absolutely! It’s sweet, creamy, and peanut butter is always a hit. Just slice the banana fresh before serving.
4. How do I keep the banana from turning brown?
Mash the banana into the oats for best results. Add sliced banana topping only right before eating.
5. Can I add protein powder?
Yes! A scoop of vanilla or peanut butter protein powder works great—just add a splash more milk to adjust the texture.
