In this recipe, I used rolled oats and almond milk as my base, and then added in peanut butter + chocolate for flavor. You can add in any of your favorite toppings!

Substitutions for this peanut butter overnight oats recipe:
Rolled Oats: I have not tried this recipe with quick cook oats. I think it would work but they might get soggier quicker. I wouldn’t recommend it. Irish/Steel Cut Oats will not work in this recipe. If you need a Steel Cut Oats recipe, this is the one we love!
Greek Yogurt: You can substitute greek yogurt with non-dairy yogurt if you’d like.
Milk: You can sub almond milk for any kind of milk (dairy, Walnut Milk, oat, rice, etc). Any kind will work!
Peanut Butter– You can sub almond butter or cashew butter for the peanut butter.
Vegan: If you want to make this recipe vegan you can leave out the yogurt.
Chia Seeds: If you don’t have chia seeds you can omit them.
Chocolate Chips: You can omit chocolate chips from this recipe.
Baked Peanut Butter Oatmeal: If you prefer warm oatmeal, check out this recipe.
Other Add-ins: This recipe would be great with other add-ins like banana or coconut. Check out this Chunky Monkey Overnight Oats Recipe or Strawberry Overnight Oats.
How long do overnight oats with chia seeds last?
Refrigerator: We recommend prepping/storing these overnight oats for no more than 4 days in the fridge.
As the days go on, the oats will get softer. For best results, prep 24 hours in advance!
Freezing: We don’t recommend freezing overnight oats. They unfortunately don’t freeze well. If you need a freezer friendly recipe, you can try our Baked Oatmeal which freezes great!

What kind of oats should I use for overnight oats?
For the recipe, you’ll need to use old fashioned rolled oats. These are the only oats that will work for making overnight oats!
Why not use quick oats for overnight oats?
You can’t use quick cook or steel cut oats to make overnight oats. With quick cook oats, they can get too mushy when soaking overnight. With steel cut oats, they can’t soak up the moisture overnight. They need to be cooked with heat to make them edible. If you need a Steel Cut Oats recipe, this is the one we love!

Overnight Oats Peanut Butter Toppings and Additions:
These overnight oats are perfect as is, but you can add a lot of yummy toppings to them! Here are some of our favorite things to top overnight oats with:
- fresh fruit – berries, mango, and pineapple all go great in oats. We have a delicious berry overnight oats recipe!
- nuts/seeds – chopped peanuts, walnuts, sunflower seeds
- nut butter – a drizzle of peanut or almond butter is yummy
Do you eat Peanut Butter Chocolate Overnight Oats cold or warm?
You can eat overnight oats cold or warm! It’s up to you and your taste. I prefer to pop my overnight oats in the microwave for 20-30 seconds before eating, but if you enjoy them cold you can eat them cold!

This looks delicious! If I was going to add some bananas to the oatmeal, would you recommend adding them before or after you soak the oats overnight?

I would probably add them after they soak – I think they might get a little brown/mushy otherwise!

Another fantastic recipe that will DEFINITELY be rotation!!
