Simple and Delicious Peanut Butter Overnight Oats: The Best Healthy Breakfast

You know those mornings when you’re rushing home from the gym or out running errands, and making breakfast just feels like another thing you have to do? That’s always when I stock my fridge with a batch of peanut butter overnight oats!

No wondering what to eat or stressing about making breakfast while you’re barely awake. Just mix everything the night before, and as you sleep, the oats absorb the milk and yogurt, softening into a deliciously creamy texture. Grab them as you head out the door, and start the day feeling nourished and energized.

I have many popular overnight oats recipes made with lots of fruity and nutty add-ins, but this peanut butter version is one of my favorites. The rich peanut butter flavor really shines through and adds even extra protein when combined with the yogurt. I promise you won’t be left feeling hangry and jazzed on coffee at 10 am (is there anything worse?!).

It’s a true miracle breakfast that makes your morning feel completely under control. ✅

Key Ingredients for Peanut Butter Overnight Oats

(full recipe ingredients and instructions are included in the recipe card, below)

Old Fashioned Oats: I recommend using whole grain old-fashioned rolled oats (not quick or steel cut) because they give this recipe the best texture – creamy with just enough of a bite. Steel cut oats may still have a bit of crunch, and quick oats will turn to mush! 

Peanut Butter: For the best peanut butter flavor, use an all-natural creamy peanut butter made from just peanuts (no added preservatives or oils). 

Greek Yogurt: Tangy plain Greek Yogurt complements the creamy peanut butter and adds an extra boost of protein, so you stay full. You can also use a vanilla-flavored yogurt for extra sweetness or dairy-free yogurt if you prefer.

Almond Milk: I prefer using a plant-based milk, such as almond milk, for overnight oats, but choose your favorite. Milk adds the necessary moisture to soften the overnight oats.

Chia Seeds: I like adding chia seeds to my overnight oats for an extra dose of healthy fats and fiber. 

Cinnamon: Rich peanut butter and warm cinnamon are a match made in heaven! 

Maple Syrup and Vanilla Extract: Just a touch of sweetness and a hint of vanilla make these peanut butter overnight oats irresistible (without them, they can taste a little bland).

(Optional) Protein Powder: For even more protein, add a scoop of your favorite protein powder. You won’t even taste it!

How to Make Peanut Butter Overnight Oats

(full recipe ingredients and instructions are included in the recipe card, below)

Making peanut butter overnight oats is a simple 2 step process: mix and rest!

After the peanut butter overnight oats have chilled, give them a quick stir. They should be really smooth and creamy, but if they’re too thick for your liking, add an extra splash of almond milk to loosen them up.

Peanut Butter Overnight Oats Topping Ideas

While these peanut butter overnight oats are delicious all on their own, topping them with additional fresh fruit or other toppings is always a good idea. 

I love serving my bowl with fresh raspberries, blueberries, or strawberries (sometimes all 3!), or even bananas or fresh fruit jam. (Kind of like a peanut butter and jelly situation. 😊) For extra texture, add a drizzle of creamy or crunchy peanut butter, sliced nuts, shredded coconut, or bites of chocolate chips.

How Long Do Overnight Oats Last?

These peanut butter overnight oats store well in the fridge for 3-5 days as long as they’re kept in an air-tight container. The longer they sit, the more liquid the oats soak up – so just know they’ll get softer with time. I like to make a batch to enjoy for 2-3 days, then make another mid-week so the texture is always at its freshest.
