Peanut Butter powder powers up the flavor and nutrition of oatmeal with more protein. Yet, it doesn't add a lot of fat and calories.
The powder is easier to mix than regular peanut butter and is simple to find in most grocery stores. Once you try it, you’ll find yourself adding it to smoothies, muffins, marinades, and dressings…the sky’s the limit!

Here you’ll find the basic formula for a single serving of breakfast (or snack) oats plus favorite variations. The recipe/formula is easy to double or triple as long as you remember that the ratio of oats to liquid is one-to-one.
Ready, get set, and meal prep for an easy, breezy morning!

What is powdered peanut butter?
It’s made by roasting peanuts, pressing out the majority of their oil, and grinding them. The yummy peanutty flavor remains while most of the fat is gone. As in many regular peanut butters, a small amount of sugar and salt are added for taste.
Clearly, it’s a processed food. However, it has nutritional value as in protein with less fat and calories than regular peanut butter. Additionally, it offers fiber, and minerals, such as potassium, iron, and calcium.
Please do a quick check of the label for sugar and salt because some brands add more than others. Available brands include PB2, Peanut Butter & Co., PBfit, Naked PB, and Walmart’s Great Value house brand.
Here’s a recent comparison of some of these from Barbend, a great blog for weight lifters and other strongman athletes.
Necessary Ingredients
- Rolled oats
- Milk
- Peanut butter powder
- Vanilla extract
- Salt (optional)
🌾Rolled oats: Please use rolled oats and not instant, quick-cooking oats or steel-cut. Sometimes the carton will also say “old-fashioned.” If you have celiac disease or a sensitivity to gluten, check the label for the words “gluten-free.”
🥛 Milk: Use your favorite! I love ultra-filtered milk from Fairlife or Mootopia (H-E-B), which has no lactose, fewer carbs, and more protein than regular milk. However, plant-based milks work just fine and taste good.
Here’s a comparison of the amount of protein in plant-based milks from my dietitian colleagues, the Practical Dietitians!
🥜 Peanut butter powder: Any of them will be fine in these oats, but for flavor’s sake, stay away from the chocolate-peanut butter powder combos. These will not taste right!
Vanilla: (Affiliate link) Madagascar vanilla has terrific flavor, but any will work. Use whatever you have on hand.
🧂 Salt: A dash heightens the sweetness of the grains and nuts, but is not really necessary, especially if you plan to add toppings like fruits, yogurt, or chopped nuts!
🥄How to make
If ever there was a no-recipe recipe, Overnight Oats with Powdered Peanut Butter is it!
Keep in mind that you can add more milk for a creamier bowl of oats and more peanut butter to amp the flavor!
Wash your hands, lathering with soap and rinsing with running water for 20 seconds, before starting.
1️⃣ Pour the oats into a jar or small to medium bowl. To avoid off flavors, use glass or ceramic vessels.
2️⃣Mix the milk with all flavorings: powdered peanut butter, maple syrup, vanilla, and salt (optional).
Whisk until milk is uniform in color, however, it's okay if a few lumps of peanut butter powder remain.
3️⃣Pour the flavored milk over the oats and mix well.
4️⃣ If using a jar, you can put the lid on and shake everything up.
5️⃣Place in the refrigerator for at least four hours and up to three days.
5️⃣ Enjoy with toppings like berries, craisins, raisins, chopped nuts, and a dollop of yogurt. 🫐
Tips and storage
Be sure and give the oats a good stir before digging in because the oats at the bottom of the jar or bowl absorb more liquid and are softer than those on the top. Also, some of the peanut butter powder settles on the bottom and needs redistributing.
❄️Storage: Overnight oats are best when eaten within four days and may be stored in the refrigerator for that amount of time.
You can meal prep and refrigerate them in (affiliate link) individual jars, or mix up a batch of three or four servings in a large bowl. After stirring it up, scoop out what you will eat in the morning.
Favorite Variations
🍎 Apple-cinnamon peanut butter oats: Omit the vanilla (or not), and add a fourth cup of chopped, unpeeled apples and half a teaspoon of cinnamon. Just as delicious with pears.
🍌 Banana-chia peanut butter oats: Mash half a sliced, ripe banana in your jar or bowl. Top with oats and a teaspoon of (affiliate link) chia seeds. Pour flavored milk in and mix carefully. Note: This variation may require a slightly larger jar.
PB&J: Add a teaspoon (or two) of your favorite jam as a topping!
Add-ins, toppings
This is a completely customizable bowl of oats. With dairy milk, it’s vegetarian. With plant-based milk it’s vegan.
Here are some ideas for extras to stir in or top your oatmeal.
- Berries: blueberries, sliced strawberries, raspberries
- Nuts: chopped peanuts, slivered almonds
- Yogurt: Plain or vanilla flavor, regular or Greek yogurt (adds protein and calcium)
- Dried fruit: Craisins, raisins, currants, blueberries, apricots, apples, pears
How healthy are overnight oats with peanut butter?
Most sources describe oats as heart-healthy since they are proven to lower cholesterol, help with weight management, and benefit gut health.
🌟Fiber: It may be the soluble fiber in oats, prebiotic beta-glucan, that promotes the release of peptide YY, which helps with appetite control. The fiber may also slow glycemic response, supporting steadier blood sugar for diabetes.
Oats also contain vitamins, minerals, and polyphenols like avenanthramides, that are anti-inflammatory and antioxidant, and fight processes in the body that promote aging and disease.
Oats have slightly more protein than many other cereal options, which is a reason they are beloved by body builders.
Peanut Butter Powder: This ups the protein, making the overnight oats a good breakfast choice to get you through the morning, fueling your muscles and bones.
Milk: Any type, plant-based or dairy, will have calcium for your bones, and many milks have additional vitamins and minerals that help with calcium absorption and have other health-giving benefits.
FAQ❓❓❓
So many questions about overnight oats with peanut butter powder!
Water is perfect for anyone who is trying to lose weight because, of course, it does not add any calories. Milk has some calories, but it also has more protein, carbohydrates, and, of course, calcium, as well as other minerals.
Milk has the advantage when it comes to building muscle and bone.
Yes. Cover your bowl and place it in the microwave for 30 to 60 seconds. You may want to add a little extra liquid if heating causes the oats to absorb it all.
It has fewer calories, dramatically less fat, and slightly less protein and fat-soluble vitamins than regular peanut butter. It often has, however, some added sugar and salt.
In other words, it's a toss-up, depending on your goals. For weight management, the powder is a good choice, while for a peanut butter and jelly sandwich, regular peanut butter works best.
The powder is also easy to add to smoothies, marinades, frosting, and much more!
Instant oats are cut finer than rolled oats, so they dissolve, creating mush when soaked overnight.
