The Breakfast Idea You’ve Been Looking For: Perfect Peanut Butter Overnight Oats!

Whenever I’m stuck in a breakfast rut (aka nearly every week), I pull out my favorite easy make-ahead breakfast recipe: peanut butter overnight oats! It’s simple, it’s sweet, and it packs in all the filling, nutrient-rich yumminess you need for a bright morning. Think: the nutty, gooey goodness of creamy peanut butter, thick ‘n satisfying fiber-rich oats and the perfect balance of sweet freshness with bright red strawberries (or your favorite fruit).

Everything You Need To Make This Peanut Butter Overnight Oats Recipe

  • Peanut Butter: Ah peanut butter, the star of this peanut butter overnight oats recipe! I like to use unsalted, natural creamy peanut butter. You can use a salted one if you’d like a salty breakfast treat, or you can use a nut or seed butter of your choice!
  • Rolled Oats
  • Chia Seeds
  • Coconut Cream or Yogurt: Coconut cream lends a much creamier texture to your overnight oats, but yogurt is so much easier to scoop! The yogurt-style peanut butter overnight oats are still just as good, so don’t worry too much about missing out. Be sure to use your favorite yogurt, as the flavor will be super noticeable in your oatmeal.
  • Vanilla Extract
  • Pure Maple Syrup
  • Milk: use your favorite milk to make these peanut butter overnight oats. I like using unsweetened vanilla almond milk, but you could be more keen on regular oatmilk. You can try the drinking coconut milk (located in the milk aisle), soy milk and so much more.
  • Fresh Fruit: One of my favorite components of making overnight oatmeal. The fresh, naturally sweet flavor of fruit helps to even out the rich creaminess of overnight oats. And, well, if you use strawberries, blueberries or even raspberries, I think that fruit flavor pairs so well with the peanut butter overnight oats. Think: PB&J. 🙂

How to Make Peanut Butter Overnight Oats

You’re gonna love learning how to make overnight oats with peanut butter—not only because you can easily swap the peanut butter out for another nut or seed butter of your choice, but also because it’s downright easy! 

Get Ready

The first thing I like to do when making anything in the kitchen is get ready! For this overnight oatmeal recipe, I start with washing and drying my favorite overnight oats jars. I’ll then set them aside, but at the ready for filling!

Mix it Up

Now, we’re ready to start adding all the ingredients to a medium-sized mixing bowl. Some folks like to add their ingredients straight into a jar or jars, but I find that kinda annoying and hard to stir. So, add in all of these yummy ingredients and start stirring. You’ll want to whisk everything together until it’s all very well mixed and no clumps of chia seeds, yogurt or coconut cream remain. Now, pour your overnight oatmeal mixture into your jars.

Top & Seal

You can top those overnight oats with any kind of dry topping you feel will keep nicely all night long (or even days long) atop this moist overnight oatmeal mixture. I usually skip this step and, instead, place my topping on my oatmeal the day of enjoying. Go ahead and seal your jars.

Store & Enjoy

Place sealed jars in the refrigerator for 3-5 days. Your oatmeal will only need a few hours before they’re deliciously creamy + thick and ready to eat, but you can wait ’til morning if that’s how you roll. 😉

Keepin’ It Fresh: How Long Can I Store These PB Overnight Oats?

The best thing about overnight oats is that you can make a single, double, or triple batch in advance and have a few jars on hand for the next 3-5 days’ breakfast! But first, how long can you really keep these peanut butter overnight oats?

  • Made with store-bought milk: Feel free to keep your overnight oats for up to 5 days. The fresher all of your ingredients are, the closer to 5 days your overnight oats will keep. Any longer than this time period may result in spoiled oatmeal.
  • Made with homemade milk: A few readers have let me know that, when making overnight oats with homemade milk, the overnight oats will have a shorter storage life. Since homemade milk can usually only keep for 3-4 days, that’s how long your overnight oats will last. Make sure to take into account the fact that the overnight oats will usually sit overnight before you even try them, so that minuses about a half day to a day.
  • Use the freshest ingredients: I know, I know, it’s gonna be hard to resist that half-eaten container of yogurt in your fridge. But how much longer will that yogurt last? If it’s got just 1/2 day left in it, don’t use it to make peanut butter overnight oats! It will totally spoil. So use the freshest ingredients, and you’ll get the longest lasting overnight oats!

Gooey peanut butter, thick ‘n creamy oats, layered with fresh-cut strawberries for the best peanut butter overnight oats. A gorgeous breakfast that’ll make every morning bright!



Peanut Butter Overnight Oats

  • 1 cup rolled oats
  • 2 teaspoons chia seeds
  • ¼ cup peanut butter
  • ¼ cup + 2 tablespoons coconut cream or vanilla yogurt
  • 1 teaspoon pure vanilla extract
  • 2 teaspoons to 2 tablespoons pure maple syrup
  • 1 cup milk of choice


  • Fresh strawberries or your favorite fruit
  • peanut butter for layers or topping


  1. Set aside 2-3 resealable jars. Here are the overnight oats jars that I use – if using these, set aside 3 jars. You can also use mason jars.
  2. Add all peanut butter overnight oats ingredients to a mixing bowl for easier stirring. Stir until well mixed. If using coconut cream, make sure no coconut cream clumps remain after stirring.
  3. Pour overnight oatmeal mixture into jars and seal.
  4. Store overnight in the refrigerator for 3-5 days, depending on freshness of ingredients. Right before serving, top with fresh fruit and other desired toppings.


Overnight oats will become thicker as each day passes. If desired, add non-dairy milk and mix well to thin it out. Enjoy cold, or heat in the microwave in 20-second increments until warm.
