These chocolate peanut butter overnight oats are the latest addition to our overnight oats series! So far, we’ve brought you a maple pecan version and an apple cinnamon version, and these chocolate peanut butter oats are sure to be another favorite. When it comes to meal prepping breakfast, it can be easy to get bored. You may find yourself routinely making the same egg bake, overnight oats, or smoothies. The key to keeping your breakfast interesting is to keep on trying new flavor combos – which is where these overnight oats come in! They’re rich and chocolatey, but not overly sweet, making them a fantastic way to get excited about your breakfast again.

How to Make Chocolate Peanut Butter Overnight Oats

One of the reasons we love overnight oats is because they are so easy to make! Just follow the steps below to make your oats:

  1. Portion out the oats. Line up 4, 8-ounce mason jars and pour 1/2 cup overnight oats into each one.
  2. Blend the remaining ingredients. Next, you’ll blend or whisk together the peanut butter, milk, cocoa powder, and maple syrup until smooth.
  3. Pour the milk mixture over the oats. Finally, you’ll pour about 2/3 cup of the milk mixture over the oats, then seal the jar and refrigerate overnight.

Q How long do overnight oats keep?

These oats will keep for up to 5 days in the refrigerator, so they are great for making ahead for the week!

Q What’s the best milk to use for overnight oats?

We’ve found that whole, grass-fed milk, almond milk, and cashew milk make great options for overnight oats. If you’d like to use coconut milk, we recommend using a boxed coconut milk beverage or trying light coconut milk, as full-fat coconut milk results in overnight oats that are a bit too thick.

Q Can I substitute anything for the peanut butter?

Absolutely! If you can’t tolerate peanut butter, you can substitute almond butter or sunbutter in its place.

Q Do I have to make these in individual mason jars?

Nope! If you’d prefer not to make individual portions, simply mix all of the ingredients together in a large container – then spoon out your desired portion when you’re ready to eat.

    Sounds really good. What is an “overnight ” oat?

    What do we do with the rest of the milk mixture (1/3) that we have leftover?

    YuM!! I may have added a bit more cocoa than I should have so I topped with chopped peanuts and it was so delicious!

    I don’t normally leave comments, but these were AMAZING. I’m usually a savory over sweet person and like to start my day with eggs, but I’ve been trying to get more fiber into my diet and these are an easy and delicious way I can do that regularly. Thank you for all your wonderful recipes and hard work!

    Do you stir the jar after pouring the milk mixture over the oats, before sealing? (The instructions above do not indicate to but the “How to Make Overnight Oats” guide says to stir first.)

    These were good! Going to use only 1 T cocoa powder next batch, as the chocolate overpowered the peanut butter (mine are much darker than pictured, used the same portion and brand of cocoa powder as above).

    Do you think you could leave out the maple syrup? Or any healthy substitutions?

      Sure, you can definitely leave out the maple syrup, or add any other natural sweetener you like (stevia, honey, etc).
