Peanut Butter Overnight Oats: Ingredient Substitutions
- Milk Any non-dairy or regular dairy milk works great: whole milk, almond milk, coconut milk, etc.
- Honey. maple syrup is a great substitute for honey.
- Peanut Butter. both creamy and crunchy work great. Or use your favorite nut or seed butter (almond butter, sunflower seed butter, etc.)
- Old fashioned oats. Quick-cooking oats, rolled oats and steel cut oats can all be used to make this recipe.
How to Make Peanut Butter Overnight Oats
There are two ways to make this peanut butter overnight oats recipe – either in a blender or by hand. I will show you both.
Blender Method
Begin by blending the ingredients (except for the oats) together. Blending the chia seeds results in a smooth and creamy base mixture that doesn’t get stuck in your teeth!
Even though I like to blend the chia seeds, the texture is the best when the oatmeal retains its hearty, chewy texture and is not blended into the other ingredients.
So add the oats last and pulse once to combine.
Mix By Hand
Whisk or stir all the ingredients together in a large bowl. Then, let the mixture sit before transferring glass jars.
Then transfer to glass jars with lids and store overnight to enjoy in the morning.
If desired, you can add the toppings of your choice to the peanut butter overnight oats before refrigerating. Here are some suggestions:
- Fresh fruits (bananas, berries, apples, citrus fruits, etc.)
- Nut Butters (like this vanilla almond butter or this homemade peanut butter)
- Chia Seeds
- Candied almonds
- Cinnamon Sugar pecans
- Honey or Maple Syrup
- Strawberry Sauce
- Chocolate chips or cocoa nibs
- Nuts (almonds, cashews, peanuts, etc.)
- Dried Fruits (cranberries, apricots, rasins, etc.)
Serve
I suggest serving the peanut butter overnight oats chilled. If you prefer to eat oatmeal warm, you can heat them up (or try this stovetop peanut butter oatmeal recipe).
Store
Store in a glass jar with a lid for up to 5 days in the refrigerator or in the freezer for up to 2 months. Thaw slowly in the refrigerator.
Peanut Butter Overnight Oats Recipe FAQs
If stored in an airtight container, like a glass jar with a lid, overnight oats can be stored in the fridge for up to 5 days (although they never last that long in my house).
Yes. You can use quick-cooking oats in place of old-fashioned oats. The benefit of making this choice is that it doesn’t need to soak as long! These peanut butter overnight oats only need to “soak” for one hour if quick oats are used. However, they can still be enjoyed the next day (and a few days after that)!
Protein. One serving of these peanut butter overnight oats recipe has 11.4 g of protein.
Fiber. Another nutrient we never get enough of, but that’s abundant in chia seeds!
Iron. Chia seeds are rich in iron, and are a great superfood to add to your diet if you’re looking to increase your iron intake.
Thickener. Chia seeds absorb the milk and thicken the mixutre.

Once these are made, how long can they last in the fridge? Like if I make them on Sunday for my weekly meal prep will they still be good Friday?

I am obsessed with these overnight oats! Best recipe I’ve tried! Thank you

Hi
I was wondering if the nutritional information is per jar or for the whole recipe?
Thanks these were yummy!
Are you using squeezable peanut butter in this? The aesthetics are amazing! (Also, I just discovered this recipe and I’m making it right now) 🙂
What size mason jars did you use?
Hey PJ! I believe I used 8 oz (half pint) mason jars!
I’m not sure why I’ve been so scared to try overnight oats but boy and I glad I did! They are so easy and so yummy! I even take them to have for lunch. The peanut butter makes it over the top amazing. Thank you!!!
LOL I totally understand! It took me a while to hop on the overnight oats train! I’m glad you like them!
Not sure how I feel about eating cold oatmeal. I guess it’s a mental thing – I mean I eat cold cereal. Hmmm…thoughts on microwaving it a bit???
I’ve made overnight oats many times before, but never with blended chia seeds. I’m with you on hating them getting stuck in your teeth, and I love my oats thick too! Can’t wait to try this version 🙂
Lol those chia seeds can be so pesky! You will love this version!
Great taste, but the texture not so much….I have a ninja blender and I thought I would be ok, but my chia seeds didn’t grind up. Next time I think I will pre-grind in my coffee grinder, because, let me tell you, whole chia seeds versus ground is a whole new world….not in a good way.
I know you say to use a vitamix, however I think I would mention maybe pre-grinding your chia seeds if you don’t have one. Other than that, great recipe!
