Peanut Butter Banana High Protein Overnight Oats - A Creamy, Satisfying Make-Ahead Breakfast
Ingredients
Method
- Mash or slice the banana. For a smoother, sweeter base, mash it. For more texture, slice half and save the rest for topping.
- Mix the wet ingredients. In a jar or bowl, whisk milk, Greek yogurt, peanut butter, vanilla, and sweetener until smooth. If using protein powder, whisk it in now.
- Add dry ingredients. Stir in oats, chia seeds (if using), and a pinch of salt. Fold in the banana.
- Adjust consistency. The mixture should be slightly loose. Add a splash more milk if it feels too thick; the oats and chia will absorb moisture overnight.
- Cover and chill. Seal the jar or bowl and refrigerate for at least 4 hours, preferably overnight.
- Stir and serve. In the morning, give it a good stir. Add a little milk if you want it looser.
- Top it off. Finish with sliced banana, a drizzle of peanut butter, and a sprinkle of cinnamon or chopped peanuts for crunch.
Why This Recipe Works

This combo hits all the right notes: creamy oats, nutty peanut butter, and sweet banana in every bite. The protein boost keeps you full longer, while the fiber from oats helps steady your energy.
It’s also completely customizable—swap the milk, adjust the sweetness, or add toppings you love. Best of all, the texture turns luxuriously thick overnight, so it eats like a pudding-meets-parfait with zero effort in the morning.
What You’ll Need
- Old-fashioned rolled oats (1/2 cup) – for hearty texture and slow-release energy
- Milk of choice (2/3 to 3/4 cup) – dairy or unsweetened almond, soy, or oat milk
- Greek yogurt (1/3 cup) – boosts protein and creaminess
- Protein powder (1 scoop, vanilla or unflavored) – whey or plant-based
- Peanut butter (1–2 tablespoons) – creamy or natural for classic flavor
- Banana (1 small to medium, mashed or sliced) – natural sweetness and potassium
- Chia seeds (1 teaspoon, optional) – thickens and adds omega-3s
- Maple syrup or honey (1–2 teaspoons, optional) – for extra sweetness if needed
- Vanilla extract (1/4 teaspoon, optional) – rounds out flavor
- Pinch of salt – brightens everything
- Toppings (optional) – sliced banana, chopped peanuts, cacao nibs, cinnamon, or a drizzle of peanut butter

How to Store
Keep the oats covered in the fridge for up to 3 days.

Benefits of This Recipe
- High protein: Between Greek yogurt, protein powder, and peanut butter, you get a solid protein boost to keep you satisfied.
- Balanced nutrition: Carbs from oats and banana, healthy fats from peanut butter, and fiber from oats and chia create steady energy.
- Meal-prep friendly: Make once, enjoy for days.
Perfect for busy mornings or post-workout fuel.
- Budget-friendly: Simple pantry staples, no fancy ingredients required.
- Customizable: Easy to tailor for dietary needs—gluten-free oats, dairy-free yogurt, or plant-based protein.
Pitfalls to Watch Out For
- Too thick or too thin: Protein powder and chia can over-thicken. Start slightly loose and adjust with milk in the morning.
- Gritty texture: Some protein powders stay grainy. Whisk thoroughly or blend the wet ingredients first for a smoother result.
- Overly sweet: Bananas vary in sweetness.
Taste before adding maple or honey, especially if using sweetened protein powder.
- Soggy toppings: Add nuts, cacao nibs, or extra banana right before serving to keep them crisp and fresh.
- Using quick oats: They can turn mushy. Rolled oats offer the best texture for overnight oats.
Recipe Variations
- Chocolate Peanut Butter Banana: Add 1 tablespoon cocoa powder or use chocolate protein powder; top with cacao nibs.
- Crunchy PB Swirl: Use crunchy peanut butter and add roasted peanuts or granola just before eating.
- Dairy-Free: Use almond or soy milk and a coconut or almond milk yogurt; choose a plant-based protein powder.
- Salted Caramel Twist: Stir in a pinch of flaky salt and a teaspoon of date syrup; top with sliced banana.
- PB&J: Layer with a spoonful of chia jam or your favorite fruit spread before chilling.
- Extra-Fiber Boost: Add 1 tablespoon ground flaxseed and an extra splash of milk to balance thickness.
- Nut-Free: Swap peanut butter for sunflower seed butter or tahini; add a touch more maple if using tahini.
FAQ
Can I make this without protein powder?
Yes. Increase Greek yogurt to 1/2 cup and reduce milk slightly to keep the texture creamy. You’ll still get plenty of protein.
What kind of oats work best?
Old-fashioned rolled oats give the best bite.
Steel-cut oats won’t fully soften overnight, and quick oats can turn mushy.
How do I prevent clumps from the protein powder?
Whisk protein powder into the milk and yogurt first, or shake everything in a jar. If it’s still clumpy, blend the wet ingredients before adding oats.
Can I heat overnight oats?
Absolutely. Warm them gently on the stove or in the microwave with a splash of milk, stirring often.
Add fresh toppings after heating.
How ripe should the banana be?
Use a spotty, ripe banana for natural sweetness and better mashability. Greener bananas will taste starchier and less sweet.
Is this recipe gluten-free?
It can be. Use certified gluten-free oats and check your protein powder and yogurt labels to be sure.
How much protein does this have?
It varies by brands, but expect roughly 25–35 grams of protein per serving with Greek yogurt and a standard scoop of protein powder.
Can I prep multiple servings?
Yes.
Multiply the ingredients and portion into separate jars. They’ll keep well for up to 3 days; add fresh fruit the day you eat it.
What’s the best peanut butter to use?
Natural creamy peanut butter works well for flavor and mixability. If yours is very thick, warm it slightly so it blends smoothly.
How do I reduce calories without losing flavor?
Use powdered peanut butter for part of the peanut butter, choose nonfat Greek yogurt, and go with unsweetened almond milk.
Add cinnamon and vanilla for extra flavor without added sugar.
