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.

    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. Danielle @Wholefully

      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 =)

  2. Jessica S.

    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. Danielle @Wholefully

      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 =)

  3. Lezlie

    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. Danielle @Wholefully

      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! =)

    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

  5. Brie

    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. Danielle @Wholefully

      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!

  6. Aliesha

    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. Danielle @Wholefully

      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! =)

  7. Stephanie

    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. Danielle @Wholefully

      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!

  8. Karina

    This tastes like dessert, it is SO good and rich and just so thankful to have this recipe around for mornings when I’m craving something sweet.
    I’ve tried this peanut butter chocolate recipe and the blueberry overnight oats one too and they’re both out of this world delicious!

    I substituted PB2 powdered peanut butter in this and instead of maple syrup I added about 1-2 tbsp monk fruit sweetener.

    Thank you for these great recipes!

  9. Amy Wills

    Okay. So first of all, I love this blog and the recipes in it, and one recipe that I disliked doesn’t mean I don’t like this baking blog (actually, I like it very much). Just, I hope no one takes this personally (:

    The flavour in this recipe was so intense, it made me feel sick. It felt like I was eating an oversized tub of extremely sweet chocolate icing. It was just wayy too rich for my liking- almost inedible- I couldn’t finish it.

    Sorry, and I hope to find more recipes that I do like, on this blog.

    1. Danielle @Wholefully

      Hi, Amy! Thanks so much for your feedback. We really appreciate it!

      If you find the oats are too rich for you, always feel free to adjust the recipe to suit your tastes! You could try using 1 tablespoon each of peanut butter and cocoa powder instead of 2, for example. Or increasing the liquid to thin it out a bit. Or both! With a bit of experimenting we know you’ll find something that’s just right for you. If you give any of these suggestions a go, let us know how it turns out for you!

      1. Danielle @Wholefully

        Hi, Teresa! Yes, you can! The texture will be a bit chewier and you’ll likely need to increase the liquid by about 1/4 cup, but it should work out just fine. In fact, lots of folks prefer the chewy texture of steel cut oats to the more pudding-like texture you get with rolled oats. If you give it a go, let us know how you like it!

  10. Mya

    Since this makes 2 servings if I’m meal prepping for the week should I be doubling the recipe? Just want to double-check before I get started!

    1. Danielle @Wholefully

      Hi, Mya! You definitely can double this recipe! I usually make the whole recipe as written in one jar—so if I’m prepping a a few jars for the week I’ll add 1/2 cup of rolled oats to each jar, 1 tablespoon of chia seeds to each jar, etc., all the way down the ingredient list. You could also double the recipe and mix it all up in a big bowl then divide it among your jars/containers of choice.

      It really depends on how hungry you are in the mornings—this truly could be one or two servings. Some mornings I only eat half of the jar, but sometimes I eat the whole jar! Once you start making them, you’ll figure out what works best for you. Happy meal prepping!

  11. Toni Ober

    I’m confused about the serving size and the calories listed. Is the 345 calories for the whole thing, everything you mix up? If I eat all of it, is it 345 x 2?

  12. JD

    Are the nutrition facts inclusive of 1 Tbsp of maple syrup as in your base recipe? I understand numbers aren’t everything, but a calorie deficit is required for weight loss.

    1. Julie Grice

      The numbers are automatically calculated, so I’m not sure what amount of maple syrup they pulled for their calculations.

  13. Michelle

    This has been my go to breakfast! Almost feel guilty eating it because it tastes too good to be nutritious LOL.
