Peanut butter overnight oats are a delicious and filling make-ahead breakfast! They’re thick, creamy and full of rich peanut butter flavor.
Peanut Butter Overnight Oats make breakfast easy!
Overnight oats are one of my breakfast staples, and these peanut butter overnight oats are one of my favorite flavor variations. I just love the rich peanut butter flavor and the delicious chewy texture of the soaked oats. The best part is that all I have to do in the morning is grab my jar of oats out of the refrigerator, add sliced banana or fresh berries and enjoy!
Hearty oats made with peanut butter, Greek yogurt, chia seeds and cinnamon make a healthy, filling breakfast to power you through your morning. If you love make-ahead breakfasts you might also enjoy my Chia Seed Pudding, Baked Oatmeal and Breakfast Burrito recipes.
What are Overnight Oats?
Overnight oats are an easy make-ahead breakfast made by soaking old-fashioned rolled oats in milk. As they chill in the refrigerator, the oats soak up some of the milk, softening a bit while also retaining their chewy texture. Overnight oats are usually eaten cold, but you can warm them in the microwave if you prefer.
Ingredients You’ll Need
- Old-Fashioned Rolled Oats: This recipe works best with old-fashioned rolled oats. I do not recommend using quick oats, since the texture would be too mushy. Steel cut oats will produce a much chewier texture and would need to be soaked for at least 24 hours before eating.
- Milk: Use any type of milk, dairy or non-dairy. I like to make this recipe with almond milk.
- Greek Yogurt: Plain Greek yogurt adds protein and makes the oats extra creamy. You could also use vanilla Greek yogurt for more sweetness.
- Peanut Butter: I find that 1 tablespoon of peanut butter gives just enough peanut butter flavor that you know it’s there without it being overpowering. If you’re craving lots of peanut butter flavor, I’d add another tablespoon of peanut butter to your oats.
- Chia Seeds: These help to thicken the oats. The chia seeds also add fiber and protein and omega-3 fatty acids.
- Pure Maple Syrup: Brings a little sweetness. Adjust the amount to your tastes.
- Vanilla Extract: Adding just a tiny splash of vanilla extract to the oats before soaking them adds the most delicious flavor.
- Cinnamon: I love the combination of cinnamon, peanut butter and banana. Sliced banana is my topping of choice for these peanut butter overnight oats. You could also add strawberries, blueberries or another fruit.

How to Make Peanut Butter Overnight Oats
Combine the oats, milk, Greek yogurt, peanut butter, chia seeds, maple syrup, vanilla extract and cinnamon in a bowl or mason jar. Stir until everything is well combined. Then cover with a lid or plastic wrap.
Refrigerate overnight, or up to 4 days.
To serve, stir the oats again and then add your desired toppings. Here I added sliced banana and a drizzle of peanut butter.
Recipe Variations
- Dairy-Free: Use nondairy milk. Either omit the yogurt (the oats will still be creamy and delicious without it) or use a nondairy yogurt.
- Almond Butter: Swap almond butter for the peanut butter. Or try my Almond Butter Overnight Oats recipe!
- Add Peanuts: Chopped peanuts would add delicious crunch! Add them right before serving, to retain their crunchy texture.
- Add Chocolate Chips: It’s hard to beat the peanut butter and chocolate combo!
Meal Prep and Storage Tips
I usually make these peanut butter overnight oats one day ahead, but if you prefer to make a bigger batch you can store them for up to 4 days in the refrigerator. They will soften more the longer you store them. You can prepare individual servings of oats in mason jars for grab and go breakfasts.
Be sure to add any fresh fruit or other toppings right before serving.

I love having breakfast already taken care of the night before! These sound delicious!
Thank you, Kelly!
You can’t go wrong with PB and banana! I can’t eat dairy, but I think I could easily swap in coconut yogurt, or just use extra almond milk.
Yes, I think either of those options would work well! 🙂
Overnight oats have been my favorite breakfast since the spring, and I love that you added peanut butter! I’m going to have to try this version, Kristine! 🙂
If you try these oats, I hope you love them, Marcie!
Hi there, do you use plaine greek yogurt or flavored??
Hi Pam, I use plain Greek yogurt. If you prefer things a little sweeter, you might try vanilla yogurt.
Hi, Can you use Almond milk instead of regular milk?
Yes, almond milk will work great! Enjoy!
HOW MANY CARBS ARE THIS??
Hi how many kcals in the overnight banana and peanut butter recipe thanks
Hello Kristine,
First of all I would like to leave you a compliment. You have a very great and beautiful blog 🙂
Second, I want to thank you from the bottom of my heart for the great recipe. I love peanut butter and have been looking for a suitable recipe for peanut butter and overnight oats for a long time 🙂
Thank you very much! 🙂
I will try it out tonight and go shopping.
But I have a question about it: Can I do the oats for 2-3 days in advance or is it better to prepare them fresh every evening?
Wish you all the best.
I give you five stars 🙂
Best regards,
Nadine
P.S.: My English isn’t the best, but I hope it’s enough 🙂
Hi Nadine, Your kind words made me smile! Thank you so much for your thoughtful comment. The oats will last for 2-3 days in the refrigerator. Keep them in a covered container and stir them before using. Add the banana right before serving. I hope you love them!
