Support my blog by sharing!

This Protein Peanut Butter Overnight Oats recipe is the perfect meal prep to ensure that you have a quick and easy breakfast that will keep you full until lunch! It is full of creamy peanut butter for healthy fats and packed with 40 grams of protein per serving! 

Making overnight oats is one of my favorite ways to prepare a healthy breakfast for busy mornings. However, in order to have a balanced breakfast, it is important to ensure you are getting enough protein. Overnight oats on their own are usually carb-heavy and do not have enough protein to keep you full and prevent a blood sugar spike. Adding in extra protein by using protein powder is a great way to make overnight oats a high-protein breakfast!

This Peanut Butter Overnights Oats recipe is made with simple ingredients and is low in added sugar. If you are a peanut butter lover, this recipe is a must-try! I also have a really yummy recipe for Pumpkin Spice Overnight Oats which is another recipe high in protein! 

Breakfast really is the most important meal of the day!

As a Holistic Nutritionist, one of the first things I do when working with a client is taking a deep dive into their breakfast habits. It is so common in our society to skip breakfast, or just grab a muffin on the go, but unfortunately, this is not setting us up well for the day! It is important to start the day with a healthy breakfast that is nutrient and protein-rich, and this recipe is one that I recommend! It is quick and easy and also tastes delicious. It’s a win-win!

Oats to use for overnight oats

For overnight oats, you will want to use old-fashioned oats for best results. Quick oats or instant oats are thinner and they tend to yield a more mushy result. One of my favorite oats to use for overnight oats is the Rolled Oats and Ancient Grains from Trader Joe’s! It contains oats, amaranth, quinoa, chia seeds, and flax seeds for a hearty dose of healthy whole grains, fiber, and omega-3 fatty acids. Paired with the protein from the peanut butter, milk, and protein powder, you get a very filling and easy breakfast option! This recipe is written to use the Trader Joe’s Oats, but feel free to sub for regular old fashioned oats for a 1:1 swap. 

You also do not want to use steel-cut oats for this recipe! While there are some recipes out there that use steel cut oats for overnight oats, the instructions are different. 

Recommended Protein Powder

The flavor of the protein powder will greatly impact the flavor of the oats, so it is important to use a type of protein powder you actually like! I used vanilla for this recipe, but feel free to swap it out for a chocolate protein powder, or any other flavor you like! 

The brand of powder I recommend is FlavCity. Not only is this protein powder full of healthy ingredients, but it also actually tastes good!! Not like the chalky protein powder you can barely get down. (I know you know exactly what I mean…) 

I recommend using the FlavCity Vanilla Cream flavor for this recipe. 

Is this recipe non-dairy?

This recipe uses milk and a whey protein powder but you can easily sub to make this recipe plant-based! Use your favorite non-dairy milk such as coconut milk or unsweetened almond milk. You’ll also want to swap to a plant-based protein powder. 

If you would like this recipe to be vegan-friendly, swap out the honey for maple syrup! 

Are overnight oats gluten-free?

Yes! Oats are naturally gluten-free but if you are sensitive to gluten I recommend purchasing certified gluten-free oats to ensure there is no cross-contamination. Also, be sure that the protein powder you are using is gluten-free. (The recommended FlavCity protein powder is gluten-free!)

Ingredients for High Protein Overnight Oats

This recipe has 40 grams of protein per serving! Keep in mind that if you make any adjustments or use a different protein powder the protein content can vary. 

• Milk – I use whole milk because it adds some creaminess but you can sub for whichever type of milk you have on hand. 
• Old Fashion Oats- I use Trader Joe’s Rolled Oats with Ancient Grains, but you can easily sub for regular old fashion oats.
• Peanut butter – Adds a nutty richness that is so delicious! You could also sub for a nut butter such as almond butter. 
• Honey- This is optional, it depends on how sweet you like the oats to be. I like to add one tablespoon to enhance the sweetness of the peanut butter and the sweetness in the protein powder. 
• Vanilla protein powder – 4 servings. I used FlavCity Vanilla Cream Protein Powder

How to make Peanut Butter Overnight Oats

First, add milk, peanut butter, protein powder, and honey to a blender and blend until smooth. This is an easy way to get the smoothest consistency and help the peanut butter blend all the way into the liquid. If needed, you could also whisk them together to combine, but be sure to get all clumps out.

Then pour into a mixing bowl and then add in the oats and stir to combine.

Pour mixture into 4 small airtight containers and seal with lid. I love using a half-pint mason jar with a reusable plastic lid. This recipe will perfectly fill up 4 jars! 

 Leave overnight and enjoy the next morning!

How long are overnight oats good for?

If stored properly in an airtight container, overnight oats will stay good in the fridge for 4-5 days, making this a great option for meal prep!
