This Overnight Oats with PB2 recipe is a quick, 5-minute meal prep breakfast that peanut butter lovers will adore. It’s gluten-free, vegan, high in protein and fiber, and gives you all the flavor of peanut butter with fewer calories and fat.
Overnight oats have been on my “I need a quick and healthy breakfast” rotation for over a decade. They’re my go-to whenever I want to stay on track with eating healthier or simplify my mornings. Next to my healthy smoothie recipes, they’re the easiest make-ahead breakfast – and despite the bad rap overnight oats sometimes get in weight loss circles, they’ve been a staple in my journey since 2011.
In fact, I even wrote a whole post on using overnight oats for weight loss because they’ve helped me stay consistent, full, and on track.
I’ve made so many versions over the years, vanilla overnight oats, blueberry overnight oats, chocolate cherry overnight oats, and even Almond Joy Overnight Oats, but today’s recipe is all about peanut butter. Specifically, we’re making Overnight Oats with PB2, a lighter take on a classic favorite.
If you’ve never tried it, PB2 is powdered peanut butter made by pressing roasted peanuts to remove most of the oil and fat. What’s left is a peanutty powder that mixes into recipes and gives you all the flavor you love, but with up to 85% less fat and fewer calories. I use it all the time in my smoothies and oats when I want to keep the calories in check without sacrificing flavor.
I have a chocolate peanut butter overnight oats recipe that tastes like Reese’s for breakfast – but that one uses traditional peanut butter, which is delicious, but also adds up fast. Today’s PB2 version is just as satisfying, way lighter, and super budget-friendly.
Ingredients
- Rolled oats – Rolled oats work best for overnight oats. They hold their shape without turning to mush. If you’re gluten-free, look for certified gluten-free oats (Bob’s Red Mill is a great brand). Otherwise, I often grab bulk oats from Aldi or Costco to save money.
- PB2 (powdered peanut butter) – This is where you get that deep peanut butter flavor without the extra fat. PB2 is my favorite, but there are other brands too – even store versions at Aldi or Wegmans. It’s shelf-stable and lasts a long time, so buying a larger container from a wholesale store can save money.
- Chia seeds – I love chia seeds in overnight oats because they create a creamy, pudding-like texture and add fiber, protein, and omega-3s. You can skip them, but the oats will be softer and less thick.
- Unsweetened almond milk. I usually use almond or coconut milk because I always have them on hand for smoothies. But you can use any milk here – dairy or non-dairy. Carton-style almond milk from the grocery store dairy section works great.
- Banana (chopped). Adds natural sweetness to the oats. I use half in this recipe and freeze the rest of the banana for smoothies or another jar of oats.
- Maple syrup. Optional, but I usually add a bit the next morning if the oats need extra sweetness. Start with 1 teaspoon, taste, and adjust.
Shopping Tips
All of these ingredients can be found at grocery stores like Wegmans, Target, Whole Foods, Walmart, Aldi, or your favorite local market. You can also buy in bulk from BJ’s, Costco, or Sam’s Club. If you prefer delivery or want to stock up on pantry staples, Thrive Market is a great online option that often has PB2, chia seeds, and oats at competitive prices.

Troubleshooting & Variations
- Too thick in the morning? Stir in 1–2 tablespoons of milk to loosen it up.
- Want it sweeter? Add more maple syrup – or mash in extra banana.
- Don’t love banana? Try applesauce or skip it altogether and sweeten with syrup only.
- Need more protein? Stir in Greek yogurt, a scoop of protein powder, or even collagen powder.
- No PB2? You can use real peanut butter, but be mindful of portion size as the calories add up quickly.
How to Make Overnight Oats with PB2
Mix the dry ingredients. In a 16-ounce mason jar, add the rolled oats, PB2, and chia seeds. Stir them together first to avoid clumping when you add the liquid.
Add the wet ingredients. Pour in the almond milk and chopped banana. Stir everything together until all the oats are coated and it’s well combined.
Cover and refrigerate. Tightly cover the jar and place it in the fridge overnight (or at least 6 hours). It will thicken up as the oats and chia seeds soak.
Sweeten and serve. In the morning, add 1–2 teaspoons of maple syrup if needed. The PB2 makes it thick, so you may also want to stir in a splash of almond milk to loosen it up. Top with extra banana or chopped salted peanuts for crunch.
Meal Prep Tips
- For the week: Prep 4–5 jars on Sunday in under 10 minutes and store in the fridge. They’ll keep for 4–5 days, making breakfast one less thing to worry about during the week.
- For the freezer: Create freezer “packs” by combining oats, PB2, chia seeds, and banana in a small bag or container. On the night before, dump the dry mix into a jar, add almond milk, stir, and refrigerate. This is a great option if you want to stock up for a month.

I entered in all these ingredients into my “Lose It” app as a recipe, and it’s saying 411 calories per serving…!? The 1/2 cup of oats along are showing up as 280 calories….
Meera says
1/2 cup of old fashioned oats is typically 150 calories.

someone asked about using peanut butter and I never saw a response…….could you??
Tammy Kresge says
You can definitely stir in regular peanut butter. Stir it in when you wake up in the morning because the peanut butter will be easier to stir.
