    Protein overnight oats with old fashioned oatmeal, Greek yogurt, creamy peanut butter, and chocolate protein powder are a protein punch.

    Overnight oats are a no-cook method for making your morning oatmeal. You combined all of your ingredients in a bowl or mason jar and soak them overnight in the refrigerator. The oats become soft overnight as all of the flavors come together.

    After refrigerating, give the oats a good stir before adding your favorite toppings. You can enjoy the oats cold or you can warm them in the microwave.

    Recipe highlights

    • High protein: This single serving recipe has an estimated 17 grams of protein.
    • Make-ahead breakfast: Overnight oats are perfect for meal prep, great for busy mornings.
    • Great base recipe: Customize this with your favorite toppings.

    For more healthy overnight oats recipes, you have to try these classic peanut butter overnight oats, vanilla overnight oats, or Nutella overnight oats (okay, so maybe that one isn't exactly "healthy").

    Ingredients

    This overnight oats with protein powder recipe calls for a few ingredients you may already have in your pantry.

    Protein Powder Overnight Oats ingredients: oatmeal, chocolate protein powder, almond milk, Greek yogurt, creamy peanut butter, maple syrup, chia seeds, vanilla extract, salt, and cinnamon.
    • old-fashioned oats
    • chocolate protein powder (I use Orgain Creamy Chocolate Fudge)
    • almond milk
    • plain Greek yogurt
    • creamy peanut butter
    • maple syrup
    • chia seeds
    • vanilla extract
    • salt
    • cinnamon

    See the recipe card for quantities.

    Instructions

    Add all of the ingredients to a 12 oz jar or 16 oz jar or bowl and stir to combine until the peanut butter is completely incorporated.

    The jar in my photos is a 12 oz jar, but 16 oz will give you more room to stir.

    Mix in the protein powder thoroughly! No clumps. Here you can see all of the ingredients mixed together. You can see the comparison of a 12 oz jar versus a 16 oz jar.

    Cover and refrigerate overnight for a minimum of four hours.

    Remove from the fridge, stir the oatmeal, and serve. Enjoy your easy breakfast the next morning!

    Topping ideas: For a nice crunch, top with peanuts (chopped or whole), slivered or sliced almonds, toasted coconut flakes, or granola. Fresh strawberries, banana, and blueberries would also be tasty toppings.

    Make It Your Own!

    Here are a few ways to personalize your peanut butter overnight oats to make them your own.

    • Oats - Try protein oats for extra protein.
    • Protein powder - I use chocolate protein powder, but you can use any type of protein powder like vanilla or mocha.
    • Milk - Use any type of milk for this recipe. I wrote the recipe using unsweetened vanilla almond milk because it's low-carb, and that's what I keep on hand. Dairy and non-dairy milk will both work.
    • Sweetener - Instead of maple syrup, you can use brown sugar or honey.
    • Nut butter - Any kind of nut butter (almond butter, sunflower butter, you name it!) will work for this recipe. You could even punch up the protein with a high-protein peanut butter.
    • Maple syrup - I use maple syrup but you can also use honey (the same amount).

    What Is the Best Container for Overnight Oats?

    With all of the ingredients combined, the volume in my mason jar measures around 10-12 ounces. I use a 12 oz jar in my photos, but you'll have more room to stir if you use a 16 oz wide-mouth mason jar for overnight oats. See my side-by-side comparison photos above.

    I recommend a wide-mouth jar because it's easier to mix the ingredients with a wide opening. The mason jar also makes it easy to take my breakfast on-the-go.

    There are also BPA-free plastic options, but the glass jars seem more environmentally friendly over the long run.

    If you're dining at home or don't want to purchase a special container for your oats, you can also use a bowl and cover it with cling wrap or reusable food wraps.

    Storage

    Store leftovers in the fridge in an airtight container. Good for up to 4 days.

    FAQ

    Can I use quick oats for overnight oats?

    Old fashioned oats are the best choice for overnight oats, but quick oats will work in a pinch.
