Healthy peanut butter overnight oats

Quick to prepare. If you love oatmeal, peanut butter cookies, and make-ahead breakfast recipes that are ready as soon as you wake up in the morning, this is your kind of recipe.

Delicious peanut butter flavor. I’ve been eating overnight oats for over a decade (Quaker should just give me a job at this point), and today’s peanut butter version may be my favorite flavor so far. They are thick, filling, creamy and extra peanut buttery!

Short ingredient list. Chances are high that you already have most of the ingredients in your refrigerator and kitchen pantry to make this recipe. With just six ingredients, the peanut butter oats are so easy to make and so and tasty, you may find yourself whipping up a jar for breakfast, snack, and dessert.

High fiber + other health benefits. Just one serving gives you over 20% of the RDA for both fiber and protein. The prepared oats are also a good source of potassium, protein, healthy fats (low saturated fat), and iron.

Peanut butter oatmeal ingredients

You need the following: rolled oats or quick oats, peanut butter or powdered peanut butter, milk of choice, yogurt or banana, a pinch of salt, and your go-to sweetener.

Optional add-ins or toppings include mini chocolate chips, sliced bananas, fresh strawberries, blueberries, diced mango, or Homemade Nutella.

For vegan peanut butter overnight oats, choose plant based milk, such as almond milk or coconut milk. Use a dairy free yogurt, or go with the banana option.

The great thing about this simple overnight oatmeal recipe is that it can be made with banana or without banana. It is entirely up to you.

For a thicker texture, plus added fiber and nutrition, you can also stir in a tablespoon of chia seeds. These seeds are high in calcium, iron, B vitamins, and protein.

If you are on a low calorie or weight loss diet, many readers have reported using powdered peanut butter successfully in these overnight oats.

High protein peanut butter breakfast

Even if you do not use any protein powder, the recipe can already be a good source of protein, thanks to the milk, yogurt, and peanut butter.

To add even more protein, stir in a tablespoon of your favorite sweetened or unsweetened protein powder and use Greek yogurt or soy yogurt.

I also like to top mine with extra peanut butter, because I believe that one can never have too much peanut butter!

For under 300 calories, each serving provides over 19 grams of protein.

How to make peanut butter overnight oats

1. Start by stirring the oats, peanut butter or peanut powder, milk, yogurt or banana, sweetener, salt, and any add-ins together in a container or mason jar.
2. Press the lid on tightly, and refrigerate overnight.
3. The next morning or when ready to eat, simply open the lid, stir again, and enjoy.
4. If you prefer hot peanut butter oatmeal instead of cold oats, reheat either in a microwave or in a small saucepan on the stovetop before serving.

And yes, you can absolutely double, triple, or even quadruple the single serving overnight oatmeal recipe to feed a family or meal prep for the week.

Leftovers will keep in an airtight covered container in the refrigerator for up to five or six days. I have not tried freezing this recipe so cannot say how that would work.

The recipe was inspired by my Banana Oatmeal and Healthy Oatmeal Muffins.
