Peanut butter overnight oats are a meal prepper’s dream. They are so good, can keep for a few days in the fridge, and take less than 5 minutes to throw together.

Even better, they’re filling and it tastes like you’re eating brownie batter for breakfast. And your kids can make their own! Win. Freaking. Win.

So What’s In This Recipe?

We have oats (duh), vanilla extract (try homemade), no-sugar-added peanut butter/almond butter, milk, dark cocoa powder, chia seeds, and maple syrup.

The oats I use are old-fashioned. You can use quick-cooking oats if that is what you have on hand, but the texture may be a little mushier than old-fashioned oats.

As for the milk, use whatever you prefer/have lying around. Cow’s milk or any non-dairy milk is delicious in this. I’ve used regular milk, coconut milk, cashew milk, and almond milk and the results are always tasty.

When I say maple syrup, I mean the good stuff. The pure syrup that came from a tree, and NOT the pancake fake syrup. Don’t do it!

Can You Make Overnight Oats With Just Milk?

Yes, of course, you can but it is just going to taste like plain ol’ oatmeal. But maybe that is your thing and how you love it. More power to you.

How Long Can You Leave Overnight Oats in the Fridge?

I’ve experimented with this and it seems like 6-7 days is about the max time the overnight oats can chill in the fridge. That being said, that is a long time for a make-ahead breakfast and that makes this a meal prep dream!

When making peanut butter overnight oats I mix everything in a pint wide-mouth canning jar. It makes two servings and it is ready to go in its own carrying case. If you need to split this up amongst multiple people, mix in a bowl and then transfer to two 8 oz jam jars.

Can You Put Overnight Oats in the Microwave?

Yes! Some people want to take the chill off of the oats and popping them in the microwave for 30-60 seconds will accomplish that.


  • Mix in a smashed ripe banana and an additional 1/4 cup of milk for chocolate peanut butter banana overnight oats!
  • Add 2 tbsp of Greek yogurt for the ultimate in creamy oats.
  • Top with or mix in unsweetened coconut for an Almond Joy style overnight oat.
  • Walk on the wild side and add 1/2 tsp of mini chocolate chips for some fun and crunch.

  1. Love this I added a smashed up banana. Soooo good!5 stars

  2. These are so simple but sooo good! I haven’t found a chocolate overnight oats recipe I liked until this one and I think it’s because it uses less cocoa powder than most so it’s more balanced. The ingredient ratios are perfect!5 stars

  3. Eating mine right now. Tastes like a low sugar no bake cookie. Love it! 4 stars

  4. I’m making these again – perfect for “not quite in the routine of getting out soooo early for school” mornings!5 stars

  5. So easy and delicious — able to use PB2 to save a few calories and still got great flavor.5 stars

  6. I made mine with almond butter and subbed honey for the maple. It tasted great! My favorite fridge oats flavor so far.

  7. I LOVE LOVE LOVE overnight oats but have since found out thru an elimination diet that’s oats & my digestive system are not friends, even GF oats are no bueno. So I made this tonight for the hubs breakfast tomorrow. I will report back how much he loved it!

    • Our friend who did a Whole30 also found that oats were one of her issues. I’m sorry to hear that is the case for you too.

      Can’t wait to hear his thoughts on them!

      • So my hubs loved this! He said it tasted like chocolate peanut butter pudding. It’s a keeper. Oh & tell your friend. I made myself an overnight oat recipe using buckwheat groats & while it certainly isn’t the same, it wasn’t terrible. She might want to give it a try.5 stars

      • Who-hoo!!! Glad it was a hit with the hubs, and I love the idea of using groats.

  8. I love my overnight oats. Went thru a chocolate PB phase. Then frozen blueberries. Now I’m stuck on mochachino version that is mostly healthy. Add frozen strawberries at night and a little dark Hershey’s syrup in the am. Oh. Mylanta. I make sure I make faces so everyone thinks it’s gross, lol. 
    I use every muffin tin I have and set them in a row. Then I put Walmart’s square snack bag in each muffin hole. I start with the oats and put all my ingredients in each bag. As soon as I finish my breakfast I clean my jar, make tomorrows batch and throw in fridge. I store my little used baggies (looks like a druggie bag, lol) and reuse the next batch. Beats getting out all my dry ingredients every week. 
    Now my nieces know where the oat bags are and try to steal them. 
    You will have to experiment and give us more ideas. I love flax seed in mine also w the chia 

  9. Making some as soon as I get out of this chair! I’ve been tempted to try overnight oats, but I was too lazy to Google it. I think I even have all the ingredients.
    Have you tried any other flavors?

    • You can do it Tina! I haven’t tried other flavors. Yet. Simply because this one is so yummy and I can’t get enough.

      • Took a couple of days, but I finally have a jar in the fridge!
        I’m thinking your cooked apples would be good in oatmeal (Apple cinnamon oatmeal has always been my favorite).

      • Ohhh that’s a great idea Tina! Can’t wait to hear tomorrow what you think of them.
