High-Protein Peanut Butter Overnight Oats are a simple, tasty way to start your day with a boost of energy. They combine creamy peanut butter with hearty oats and a good load of protein to keep you feeling full and ready to go. The oats soak overnight, making them soft and flavorful without any morning fuss.
I love making these oats when I know I’m in a rush but still want something healthy and satisfying. Mixing in a scoop of protein powder with the peanut butter makes all the difference for keeping hunger away until lunch. Plus, they taste great with a sprinkle of cinnamon or a few fresh berries on top.
One of my favorite things about this recipe is how easy it is to customize. You can swap peanut butter for almond or cashew butter, add a drizzle of honey if you like it sweeter, or toss in some chia seeds for extra texture. I usually prepare a few jars on Sunday evening, so I have a quick and nourishing breakfast ready all week long.
Key Ingredients & Substitutions
Rolled Oats: These give your oats a nice chewy texture after soaking overnight. Quick oats can work too but may turn mushy. I like rolled oats for that perfect bite.
Greek Yogurt: This boosts protein and adds creaminess. If you’re dairy-free, coconut yogurt is a good swap but skip sweetened versions to keep flavors balanced.
Peanut Butter: Creamy or crunchy both work, depending on your texture preference. Almond or cashew butter are tasty alternatives if you want to change things up or avoid peanuts.
Protein Powder: Vanilla or chocolate flavors complement the peanut butter well. If you don’t have protein powder, adding extra Greek yogurt or a spoonful of cottage cheese can add protein too.
Milk: Use any kind—dairy, almond, oat, or soy. I prefer unsweetened versions to control sugar, but feel free to use what you like or have on hand.
How Can I Make Overnight Oats Creamy and Delicious?
The secret to creamy, tasty overnight oats is the right soaked consistency and good mixing:
- Add Greek yogurt and milk to oats—this combo helps create creaminess as oats absorb liquid.
- Mix protein powder well to avoid clumps before refrigerating.
- Cover and chill for at least 4 hours or overnight; this softens oats and blends flavors.
- In the morning, stir oats to evenly distribute moisture and adjust thickness with a little milk if needed.
- Adding peanut butter right before serving keeps its flavor fresh and the oats rich.
With these steps, your oats will be smooth, creamy, and packed with flavor every time!
Equipment You’ll Need
- Measuring cups and spoons – I like these for accuracy and easy portioning.
- Mixing bowl or mason jar – perfect for stirring or storing the oats overnight.
- Spoon or spatula – helps mix everything well so ingredients are evenly distributed.
- Refrigerator – essential for chilling and softening the oats overnight.
Flavor Variations & Add-Ins
- Swap peanut butter for almond or cashew butter for a different nutty flavor.
- Add a spoonful of cocoa powder or dark chocolate chips for a chocolate twist.
- Mix in berries, chopped nuts, or sliced fruit for extra texture and freshness.
- Sprinkle cinnamon or a dash of vanilla extract to boost flavor without added sugar.

Ingredients You’ll Need:
Main Ingredients:
- ½ cup rolled oats
- ½ cup milk (dairy or plant-based like almond, oat, or soy)
- ½ cup Greek yogurt (plain or vanilla)
- 2 tablespoons peanut butter (creamy or crunchy)
- 1 scoop vanilla or chocolate protein powder
- 1 teaspoon honey or maple syrup (optional, for sweetness)
- ½ teaspoon vanilla extract
- Pinch of salt
Toppings:
- 1 small banana, sliced
- Sprinkle of granola or chopped nuts
- Optional: cacao nibs or dark chocolate chunks
Time Needed:
This recipe requires about 5 to 10 minutes for preparation. Then, you’ll need to let it chill in the refrigerator for at least 4 hours, preferably overnight, to allow the oats to soften and flavors to blend perfectly.
Step-by-Step Instructions:
1. Mix the Base Ingredients:
In a medium-sized mixing bowl or mason jar, add the rolled oats, protein powder, Greek yogurt, milk, vanilla extract, honey or maple syrup (if using), and a pinch of salt. Stir everything together well until fully combined and smooth.
2. Chill and Soften:
Cover the bowl or seal the jar with a lid and place it in the refrigerator. Let it chill for at least 4 hours or overnight to achieve the perfect creamy texture and let the flavors meld.
3. Add Peanut Butter and Toppings:
In the morning, take the oats out of the fridge and give them a good stir. If you find them too thick, add a little milk to loosen the texture. Next, gently spread the peanut butter on top, layer the banana slices, and sprinkle granola or chopped nuts. Finish with cacao nibs or chocolate chunks if you like a little extra crunch and sweetness.
