No-Bake Peanut Butter Protein Bars

Although I’m a huge fan of baking, especially during the holidays, preheating the oven to 350 degrees Fahrenheit doesn’t always sound appealing.  Baking usually involves multiple bowls, countless measuring cups, and too many ingredients; don’t even get me started on the clean-up process.  One thing that always sounds appealing?  These peanut butter protein bars.

I found Blonde Ponytail’s original recipe on Pinterest a while back, and when Sunday midmorning rolled around, I walked into the kitchen, checked the cabinets, and celebrated because I had every component in stock.

Perfect to refuel post-workout, these bars contain two of my favorite things:  peanut butter and protein powder.

In order for your batch to turn out tasty, you must love your protein powder.  Plain and simple.  Chalky, tasteless powder will yield subpar bars.

I used Jay Robb egg white protein powder, and I would really, really appreciate it if you tried chocolate protein powder.  Chocolate and peanut butter?  Done and done.  In the meantime, though, these will more than suffice.

No-Bake Peanut Butter Protein Bars


1-3/4 cup creamy natural peanut butter
1 cup organic honey
2 cups protein powder
1/2 cup old-fashioned oats
1/4 cup chia seeds


1.  In a microwave-safe bowl, combine peanut butter and honey.  Microwave for 90 seconds.

2.  Add protein powder and mix well; incorporate oats and chia seeds.  Mix well.

3.  Scoop mixture into pan and refrigerate. (I waited 1.5 hours.)

4.  Cut up and store refrigerated.

Makes about 24 bars.

  1. these are pretty awesome, what a great way to make your own!

  2. Holy shizz those are so easy to make! I could even do it and I have all the ingredients on hand. 🙂

  3. These look awesome. I gave up protein powder a while back, and now try to live mainly grain-free. Do you think these would turn out without the oats? If not I’ll have to try to find some sort of paleo-friendly way of making these because I don’t want to miss out.

    • Shane, I actually considered making these bars without oats; the original recipe called for 1 cup I believe, which I reduced to 1/2, but I really wanted to leave out the oats. More PB goodness, right? 😉 Texture-wise, they held up pretty well, and I didn’t miss the extra oats at all. I bet making bars sans oats would work; I’m planning to try that next time. 🙂

      • More PB goodness is never a bad thing! 🙂 If you try before I do, let me know. This all sounds too good to miss out on haha.

  4. I love making my own protein bars… you know what I bet would make these even more amazing though? Melting some dark cholocate on top… woohoo antioxidant rich deliciousness 🙂

  5. Yep, have all these ingredients on hand as well. These are getting made, and I’ll try a chocolate protein powder for you. It’s a tough job, but someone’s gotta do it 🙂

  6. Yum! I’ve made no bake energy balls before too, and I have used protein powder. I need to make these soon!

  7. These bars look great — I am going to email a link to this page to my wife — I hope she will take the hint and make some this weekend. In theory, I could make these myself. In practice, I am a lousy cook.

    • Ha! I wouldn’t even call this cooking; it’s mixing a bunch of ingredients together and sticking them in the fridge. Let me know how they turn out!

  9. these look delicious!how long do they keep do you think?
    i think im going to make this on the weekend, although i am not sure if they would go down well with my diet 🙁

    • Let’s see … I made them Sunday, so it’s been three days, and they still taste great. I think as long as they’re refrigerated they should keep for a bit. I bet you could even freeze them, too.

  10. Those held up so well! Just out of curiosity – what brand of protein powder did you use and do you think that the quality of the powder affects the bar’s taste? I usually buy the cheapest, most generic whey.

    • I used Jay Robb egg white protein powder, which is my all-time favorite. (The original recipe called for whey, but I only use egg white.) I really like the taste of Jay Robb, so I’m sure that’s why I fell in love with the bars. Even though it’s not typical baking, you should use high-quality ingredients because they’re yield high-quality results. I think as long as you like the taste of your protein powder you’re good to go. 🙂
