If you love peanut butter, you’re going to love these peanut butter protein overnight oats! Make them in advance so you have a quick, no-cook breakfast or protein-packed snack during the day.

Disclaimer: I’m thrilled to partner with Pure Choice Whey, a Wisconsin based whey protein company, for this post. I developed this peanut butter protein oats recipe using their peanut better flavored whey protein isolate. They turned out so good! I can’t wait for you to try them.

Last month, I tried the best peanut butter flavored whey protein I’d ever had. The second I opened the container, I knew I would love it. The smell of fresh roasted peanuts exploded from the bag – just like when you open a new jar of peanut butter. My first thought was how great it would taste mixed into overnight oats. I couldn’t wait to try it!

I set up a call with Tony, the owner of Pure Choice Whey. I wanted to thank him for the samples and let him know how much I loved the protein flavors. We chatted for a while and he shared the story of how he got into the whey protein business. I was so impressed with his commitment to support local dairy farmers and his passionate for health and fitness. We had a lot in common. By the end of the conversation, I wanted to fly to Wisconsin, visit his family’s cheese farm and meet the dairy cows responsible for producing his whey. It’s not every day you find a whey protein company that cares so much about supporting local, family farms. I was more excited than ever to make the overnight oats.

Well, last week, I did. They turned out amazing! After one bite, I knew this recipe was going on my blog!

Peanut Butter Protein Overnight Oats

Overnight oats are a busy person’s dream come true. Before you head to bed, you just mix the ingredients together, cover, and let them sit in the refrigerator. When you wake up in the morning, breakfast is ready.

These overnight oats have a rich peanut butter flavor but are also packed with fiber, protein and loads of vitamins and minerals.

Ingredients Used In These Peanut Butter Protein Overnight Oats

There are endless ways make overnight oats. But, it’s using the right combination of ingredients that makes them both nutritious and delicious. Here’s what you need to make these peanut butter protein oats.

Raw Oats

For best results, I suggest using old fashioned oats. You can use quick oats, but they will be softer, and may become mushy. Steel cut oats will require more liquid and more time to soak. And, even then, may not get soft enough.

Pure Choice Peanut Better Whey Protein Isolate

Adding protein powder boosts the protein content of the oats to the 20-30 grams per meal amount I typically recommend. But, the brand and flavor of protein powder matters – a lot! If the protein tastes bad, your overnight oats will taste bad.

When choosing a protein powder, consider both the flavor and the quality. The peanut better flavored Pure Choice Whey has a rich peanut butter flavor and tastes delicious on its own, so I knew it would taste great mixed into the oats. It’s a cold-filtered whey protein isolate, so it dissolves better than some other types of protein and is lower in lactose (more on that later.) You can order the peanut better flavored protein online at Pure Choice Whey.

Skim Milk

I used skim milk for this recipe, because that’s what we drink at my house. You can use 2% or whole milk, or choose a lactose free variety, if you prefer. You can also substitute a plant-based milk like almond or oat milk. The nutritionals provided below are based on using skim milk.

Plain, Nonfat, Greek Yogurt

I first made these oats without the yogurt, but I wasn’t happy with the texture. Adding some Greek yogurt gives them a creamy texture. I used a nonfat variety because, again, that’s what we eat in my house. But, you can substitute full-fat plain Greek yogurt. I do recommend sticking to plain. Using a flavored yogurt variety would likely throw the flavor of the oats way off.

Sea Salt

Salt helps to enhance the flavors of your oats. I used sea salt, but you can also use regular table or kosher salt.

Roasted Peanuts

I refer to these oats as the best peanut butter protein oats for a reason – the peanut butter taste is real! In addition to the roasted peanuts used to make the peanut butter flavored Pure Choice whey protein, I also crush roasted peanuts and sprinkle them on the top. To maintain the crunchy texture, make sure to wait until right before you eat your oats to add the peanuts.

Peanut Butter

I considered calling these oats triple, peanut butter protein overnight oats, but it just didn’t sound right. That is what they are, though! They get topped with a drizzle of melted peanut butter.

How To Make Peanut Butter Protein Overnight Oats

Overnight oats can be made in bulk, or one serving at a time. I like to make a few servings at a time and keep them in the refrigerator. This recipe makes 4 servings.

To make them, put the oats, sea salt, peanut butter protein powder, milk and Greek yogurt in a large bowl, then stir until well combined. Cover, then store in the refrigerator for at least 8 hours.

Once the oats have thickened, pour them into four individual containers or glass jars. Right before eating, melt a teaspoon of peanut butter in the microwave until it’s runny. Top oats with crushed nuts then drizzle with the peanut butter. Enjoy!

Calories And Other Nutrient Information in Overnight Oats

This recipe makes 3 cups of oats, or four, ¾ cup servings. Each serving contains 360 calories, 39 grams of carbohydrates, 5 grams of fiber, 8 grams of sugars, 29 grams of protein, 11 grams of fat, 1.5 grams of saturated fat and 330 milligrams of sodium. It also provides 6% of the daily value for vitamin D, 10% of the daily value for iron, daily iron, 15% of the daily value for calcium and 9% of the daily value for potassium.

Enjoying Protein-Packed Overnight Oats If You Have Lactose Intolerance

If you have lactose intolerance, the thought of eating these dairy and whey protein filled overnight oats might seem impossible. Well, it’s not.

Whey Protein – The Pure Choice whey protein used in this recipe is whey protein isolate, which contains less than 1% lactose. That means, even people with known lactose sensitivity or lactose intolerance may tolerate it.

Greek Yogurt – like whey protein isolate, Greek yogurt is thought to be lactose-intolerant friendly. The straining process that gives Greek yogurt its thick and creamy consistency also removes the majority of the lactose. And, Greek yogurt contains probiotics, which can help with the digestion of any lactose that might be left. If you have a high sensitivity to lactose, you can substitute a lactose free Greek yogurt.

Milk – If you have lactose intolerance, you will want to substitute a different milk for the cow’s milk. Try using a lactose free milk or a plant-based milk, like almond, oat or hemp. Just be sure to use plain,, so that it doesn’t change the flavor of the peanut butter protein overnight oats.
