Good morning! Let’s kick off the week with a protein-packed and seriously delicious breakfast recipe!

Ever since I discovered the awesomeness of PB2 (side note: I actually resisted buying it forever, thinking WHY would anyone want powdered peanut butter when the real stuff is so amazing?), I find myself adding it to everything, including these super satisfying Overnight Peanut Butter Protein Oats.

With the hot, humid weather just around the corner, I see myself enjoying this breakfast a whole heck of a lot. It’s perfect for steamy summer mornings and all you need to do is grab a spoon and dig in. Easy as that! (Tip: Try these oats as a snack– just divide the recipe in half– so good!)

  1. What would the amount be for actual peanut butter? And what’s the like benefits of using powdered?

    1. @Aleisha: It is fat free and is very easy to add to just about anything. To turn it back into peanut butter for a sandwich, just add water or a combination of water and vegetable oil. Great stuff.

  2. I had the same thought about powdered peanut butter, but it’s kind of it’s own thing. I like how easy it is to work with and combine into mixes, batters and smoothies.

  3. yum!! Love breakfasts I can make the night before! I used to use powdered peanut butter a lot more, but these days, I prefer the real thing!

  4. PB2 has sugar in it. Why not just go for an all-natural nut butter instead? Both Macademia and Cashew have very low omega-6 profiles versus peanut and almond. I know it’s not the same taste but we can’t have everything we want.

    1. I haven’t had much success with nut butters in overnight oats (they end up all clumpy), but definitely give it a try! Sounds delicious!

  5. 2 questions:
    1. Eating it cold? I’m loving this idea… like sort of a peanut butter pudding type consistency?

    2. When you do Macros, does that mean 30g protein, 37g carb, 6g fat? I’m just trying to “zone” it… so this would be a 4-block zone meal?

    Thanks 🙂

  6. Peanut butter and banana concoctions make the absolute BEST breakfasts! I think it’s the sweet and salty combination that leaves me feeling so satisfied. I make a version of this with regular peanut butter but maybe now it’s time to give PB2 a try!

  7. If you ever get a chance, try the “Just Great Stuff” brand PB powder. It has so much more flavor than the PB2 (in my opinion) and I’m always able to find it at Wegmans.

  8. Looks amazing, can’t wait to try it! Do you recommend any adjustments to the amount of the other ingredients if we don’t include protein powder, please?
