How to Make Overnight Oats with Peanut Butter
step by step


With or Without Dairy
Making overnight oats couldn’t be easier. With five pantry ingredients, prep time is kept to a minimum. For this recipe, I’m sharing two delicious variations with easy optional add-ins to keep things interesting and to enjoy seasonal ingredients!
- Peanut Butter Overnight Oats with Yogurt: for a rich and creamy texture, I use plain whole milk yogurt and homemade cashew milk.
- Dairy Free Peanut Butter Overnight Oats (Vegan): enjoy with a combination of dairy free yogurt and milk using the original recipe, or make with or all dairy free milk and chia seeds.


Why Overnight Oats?
SO Flavorful: Oats just taste good! They have an Earthy flavor and help produce a rich creamy texture in this recipe.
Convenient: Overnight oats are simple to whip up and convenient to have in the refrigerator the next morning without having to make breakfast. Especially when you’re flying out the door!
Versatile: Make em’ gluten free overnight oats, with or without yogurt, use milk of choice, top with favorite berries, jam, seeds, diced apples or stewed apples, or bananas and chocolate chips! An overnight oats breakfast bar is fun for a small crowd.
How to Enjoy Overnight Oats
Use small Mason jars or Weck jars for individual portions. Overnight oats taste amazing chilled, however they can be gently warmed if desired. Simply pop em’ in the microwave for about 30-45 seconds. Top with your favorite fruit, nuts and of course, cinnamon (more options below).


What to Top Overnight Oats With
There are SO many options and the sky is the limit! Here are a few ideas to get you started:
- Peanut Butter Banana Overnight Oats: top oats with slice bananas just before enjoying. A sprinkle of cocoa nibs or mini chocolate chips are such a delight!
- PB&J Overnight Oats: Swirl in your favorite jam! Be sure to omit the maple syrup if making PB&J oats.
- Peanut Butter and Apples Overnight Oats: Dice up your favorite apple, top oats up to one day before enjoying. Sprinkle apples with cinnamon and enjoy! Or, give my stewed apples or blueberry compote a try (they’re make ahead ready too!).
- Simply Overnight Oats with Peanut Butter: Enjoy simply or with a sprinkle of your favorite seeds, like chia or hemp hearts.

Traci’s Tips
- Single or Multiple Batch: I make a triple batch for convenience. Simply scale up the number of servings you’d like from the single recipe and portion into individual storage containers.
- Storage Containers: Portion single serves in 8 oz Mason or Weck jars for ultimate convenience!

definitely going to try this … my favorite peanut butter (other than for baking) is also santa cruz … but, the dark roasted variety as it just has, in my opinion, a deeper flavor profile. if you haven’t tried the dark roasted, you just have to. darn … didn’t realize that santa cruz no longer exists as a company with its peanut butter now owned by jm smuckers and their juices owned by some investment firm … what a shame :(
Such an amazing recipe :) Loved and enjoyed this recipe. Definitely, I will try it. Thanks for the recipe.
Hiii Camila! Thank you for your note! So happy to hear!
