Ingredients

There are only 5 ingredients in this easy peanut butter overnight oats recipe, which come together for a fast, healthy, satisfying breakfast:

OATS:

  • 2 cups unsweetened almond milk, coconut milk, oat milk, or any milk of choice
  • 4 Tbsps chia seeds
  • 2 cups gluten-free old-fashioned oats

TOPPINGS:

  • fresh fruit, strawberries, or raspberries
  • chopped peanuts
  • peanut butter to drizzle on top if desired

See the recipe card for full information on all ingredients and instructions.

Variations And Substitutions

Use any milk: My personal favorite types of milk for these is unsweetened almond milk or cashew milk, but use any kind of milk you prefer.

Favorite Toppings:  No strawberries available? Substitute with banana slices, apples, mango, or even pineapple!  I also love adding a sprinkle of cinnamon.

Add chocolate:  If you are as big of a chocolate fan as I am, then these also are great with chocolate added. You can either break off some chips of your high quality dark chocolate bar or add some mini semi sweet chocolate chips! YUM!

Add different protein: While the peanut butter, chia seed, and oats combination offers a large amount of protein in these overnight oats already, I often add protein powder or collagen powder to my overnight oats to change them up. If you choose to do this, then your oats may need an extra splash of milk.  Other great sources of protein are Greek yogurt and cottage cheese.

Nut Butter Variation: Substituted with any nut butter you prefer or even Sunbutter.

Swap Sweeteners:  Maple syrup or honey are my go-to natural sweeteners, but if you have a preferred sweetener you like, then use that instead.

Tips for the best result

➡️Rachel’s notes:

  • Use unsweetened milk to keep the sugar down in these overnight oats.
  • Once they’re ready, stir your oatmeal really well, this will make it creamier.
  • If you set it in the fridge overnight in a large bowl, or batch, divide equally into small mason jars, bowls, or cups and top with toppings.

Storage Instructions

These oatmeal cups are perfect for meal prep because they will last 2-3 days in the refrigerator. So when you’re ready for one, just grab it and eat it!

Why are oats so good for you?

There are many benefits to eating oats such as being a healthy source of carbohydrates, fiber, and protein.  Studies have shown oats to be good at lowering bad cholesterol and balancing blood sugar.  Due to many of the nutrients like fiber and protein, oats can also help you feel fuller longer which helps keep you from overeating throughout the day. 

Is it okay to eat uncooked oats?

It is okay to eat uncooked oats however, soaking the oats, as is done in overnight oats, is important.  Overnight as they soak, the starches break down which improves digestibility and the natural phytic acid (which all plants contain) is greatly reduced that makes them more easily absorbed by your body!

Recipe FAQs

Is peanut butter good in overnight oats?

Peanut butter is delicious in overnight oats if you love it as much as I do! If not, use a different nut butter that you love instead.

Can peanut butter be mixed with oats?

Absolutely! And if you ask me, it is a great combination!

Do you eat overnight oats cold?

Yes. These oats are meant to be eaten cold like pudding, but you can heat them up in the microwave so they are more like hot oatmeal if you’d like.

Can you eat overnight oats right away?

I don’t suggest eating overnight oats right away. Leaving the oats to soak in the liquid overnight makes them more easily digestible, and more palatable, giving them a creamy delicious texture.

    These are really good and so convenient for making ahead of time! I used PB Fit (I know, not 100% clean but I prefer for PB), and topped with fresh strawberries.
