Is there a more classic sweet combination than chocolate and peanut butter? I think not. And what’s better than getting the flavor of your favorite candy (hellllooo Reese’s cups!) in the form of a healthy, easy, and nourishing breakfast? Not much! Welcome to the magic that is overnight oats!

Making up a batch of these oats is a great way to feel like you are getting a decadent dessert without actually eating a decadent dessert. These chocolate peanut butter oats are one of my favorite overnight oats recipes because there is an awesome chemical reaction that happens with the cocoa powder and the yogurt that makes chocolate overnight oats super fluffy and doubly amazing (it happens with our Coconut Chocolate Overnight oats, too).

What are overnight oats?

Overnight oats are a no-cook method of making oatmeal. Instead of cooking your oats with liquid on the stove or in the microwave, you mix rolled oats with the liquid and other mix-ins, and let it rest in the fridge for at least two hours, or preferably overnight (hence the name!). In the morning, you have a pudding-like porridge that is perfect for easy grab-and-go breakfasts. If you’re new to making overnight oatmeal and want a full primer (plus lots of other easy to make recipes), check out our Overnight Oats 101 post.

What makes overnight oatmeal so great?

There are a lot of benefits to mixing up a batch of overnight oats. Here is why they have been part of my breakfast scene for years:

  • They are the perfect make-ahead breakfast. Overnight oats take just a few minutes to mix up in the evening—we’re talking “you could make these during a commercial break during your favorite show” fast!
  • Overnight oatmeal tastes amazing. If you’ve never had cold oatmeal before, you might be off-put by the idea of eating oats this way, but trust me! This porridge is thick, hearty, creamy, and like eating pudding for breakfast! (But you can also heat up your overnight oats if you prefer, more on that in a sec.)
  • They are completely customizable. Want to make vegan overnight oats? What about gluten-free? What about mixing in your favorite fruit? All doable, because overnight oats are completely customizable. We’re covering Chocolate Peanut Butter Overnight Oats in this post (which is a great simple recipe to start with), but once you get the idea of overnight oats down, you can go wild making your own creations!
  • They can be a healthy and hearty way to start the day. Since you are in control of your overnight oats, you can make them into a super nourishing, nutrient-dense breakfast! Mix in collagen or protein powder. Add more super seeds (like chia, flax, and hemp). Reduce the added sweeteners or remove them completely. These oats can be your breakfast superfood!
  • Overnight oats are easy to make in bulk. They are a staple of many meal prep menus for good reason—you can mix up an entire week’s worth of breakfast in just a few minutes.

What do I need to make these chocolate peanut butter overnight oats?

For most overnight oatmeal recipes, you need the same base ingredients: milk, old-fashioned oats, Greek yogurt, chia seeds or ground flaxmeal, vanilla extract, salt, and some sort of sweetener (we tend to use honey or maple syrup). After that, it depends on the recipe! For this chocolate peanut butter flavor, you’ll need unsweetened cocoa powder and creamy peanut butter.

To make overnight oats, just stir together all the ingredients, spoon the oat mixture into a mason jar, and stash them in the refrigerator overnight. In the morning, your breakfast will be ready to grab and go!

Wholefully Protip

We often get asked if you can use steel-cut oats in place of the old-fashioned oats. You can if you’re okay with a chewier final texture! We recommend increasing the liquid by 1/4 cup.

Can you warm up overnight oats?

If cold oatmeal isn’t your thing (or it’s just too chilly outside to eat it), you can absolutely warm up these chocolate peanut butter oats. Just heat them in the microwave for 30-60 seconds, stirring frequently, or in a small saucepan on the stove until heated to your liking.

You can easily make these overnight oats vegan, gluten-free, or low- or no-sugar. You can swap out the milk for water, nix the chia or flax seeds, and choose different (or no) yogurt. We cover all the substitutions you can make in our in-depth overnight oats post. Here are some specific swap ideas for these chocolate peanut butter overnight oats:

  • Make it vegan or dairy-free: Use plant-based milk, plant-based yogurt, and maple syrup for sweetener.
  • Make it sugar-free: Drop the sweetener, make sure to use unsweetened peanut butter, and add 1/2 mashed ripe banana. Or use stevia or monk fruit sweetener in place of the maple syrup or honey, if you prefer.
  • Make it gluten-free: Make sure to use certified gluten-free oats.

    1. Hi Lisa! That’s the best part about overnight oats—they customize really well! Feel free to make whatever adjustments you need to get your perfect batch. Try making it with just one tablespoon of cocoa powder instead of two and see if that works better for you!

  1. I’ll try this as it looks delicious and super-healthy but the nutritional information seems off. I input the ingredients and numbers are way different.

    1. The nutritional information is automatically calculated in our system and sometimes the way ingredients are input can throw it off. We always recommend folks use their favorite online nutrition calculator to get the most accurate information. That way you can input the exact amounts and ingredients you’re using! Hope this helps =)

  2. I made this using oat milk and one tablespoon of honey, plus based on some other reviews, used only one tablespoon each of cocoa powder and peanut butter.

    What an amazing recipe! I have never had overnight oats so didn’t really know what to expect, but it was SO GOOD. I can’t wait to try some of the other variations.

    1. YAY! That’s great to hear, Sarah—we’re so glad you loved it! Thanks so much for coming back to tell us what adjustments you made and how it turned out =)

  3. Came across your recipe for the first time, and looking forward to enjoying it! I noticed your recipe called for 0-2 tbsp of honey/maple syrup. Wanted to confirm that the 0 is correct. Thanks!

    1. Hi Jessica! Yes—the sweetener is flexible. You can use as little or as much as you need to! Depending on your cocoa powder and peanut butter choices, you’ll likely need at least one tablespoon. But if you’d prefer no added sweetener, we have suggestions for how to make that work in the post! All of our overnight oats recipes are very flexible. Please feel free to adjust the amounts to suit your tastes! We hope you love them =)

  4. I added the ingredients to a food calculator because there’s no way 46 grams of fiber is correct or our guts would be exploding 😉 The calculator I used came up with around 16.5 grams of fiber for the large serving and that was using chia seeds and subtract 2 grams if using the flax. Just thought I’d share in case anyone else is interested 🙂

    1. Hi Lezlie! The 46g is actually for the Carbohydrates! All the nutritional info is listed “Item: Amount.” It can be easy to misread when the numbers are so close to the next item in the list, though! The fiber that’s calculated in our system is the 6g you see after “Fiber:”

      But we always recommend folks add their exact ingredients to a nutritional calculator for the most accurate tracking. Sometimes these automatic systems are off, especially when the recipes list alternatives for the ingredients.

      Thanks for taking the time to come back and help other people who might be interested—we really appreciate it! =)

  5. I found the recipe too intense so I tweaked it a little and now it’s close to perfection! I reduced cocoa powder to 2 teaspoons, substituted 2 tablespoons of peanut butter with only 2 teaspoons of peanut butter powder (PB2) to lower the calories, used 2 teaspoons of sugar free maple syrup and half a cup of oats, almond milk and fat free greek yoghurt. Topped it with banana slices. Was sooooo good. #addictedtoovernightoats

    1. Thanks for sharing, Rachel! We love hearing when folks make our recipes their own! So glad you love it =)

  6. Would you be able to switch out the oats to Kodiak Cakes Classic 100% Whole Grain Rolled Oats?? Trying to get more protein with it. I had WLS and a little trouble getting all my protein in.

    1. Hi Brie! We haven’t tried that so we can’t say for sure. If you want to try it out, we recommend making one and seeing how it turns out before you mix up a whole batch, just in case. The thing to watch out for is how absorbent those rolled oats are. You may need to adjust the liquid in the recipe to get it to the right consistency. Let us know how it turns out if you give it a go!

  7. Hey there! I was wondering how you calculated calories in this one? I love this recipe so much and it’s sooo tasty but when I added up all the ingredients I got around 530. Are the calories for the whole or for 2 servings? Thank you! 🙂

    1. Hi Aliesha! I’m so glad you like the recipe—it’s a favorite in my house, too! The nutritional info is per serving for the two smaller servings. It’s automatically calculated in our system, though, so if you have a favorite online nutrition calculator, we recommend going with that! That way you can input the exact ingredients and amounts you use, and get nutritional info better tailored to what you made. I hope this helps! =)

  8. Love this recipe! The only thing I will say is that the chocolate flavor was very intense for my liking, and I didn’t put enough honey the first time I made it. So the second time I only put 1 tablespoon of the unsweetened cocoa power and I made sure to put the full 2 tablespoons of honey. Delicious! I also already had crunchy peanut butter at home so I used that and it added a nice extra texture to it!

    1. Thanks so much for coming back and sharing your experience, Stephanie! We’re so glad you like them, and we love hearing about how you adjusted the recipe to suit your tastes. These oats are so flexible, and you really can make the recipe yours! Yay!
