These no-bake peanut butter chocolate protein bars taste delicious and each bar has 9 grams of protein. Plus, they’re so easy to make.

As both a personal trainer and a health coach, I have studied about the importance of fueling up after workouts. Within an hour of working out, it’s important to get a mix of protein and carbohydrates into your body — protein to help rebuild muscles and carbohydrates help to rebuild energy stores.

I went through a major phase, constantly packing RXBARs for a post-workout snack. I was buying them by the case because they were (and still are!) that good.

It didn’t take long for me to realize how much money I was spending on RXBARs and I figured I should probably reign it in. These copycat protein bars are a product of that realization, and you guys…they’re amazing. Treat yourself to a protein bar for a fraction of the price! I can’t wait to experiment with more flavors. Maple sea salt, I’m looking at you!

Why I Love These Homemade Protein Bars

  • High in protein! Just like my regular easy protein bar recipe, these bars are packed with protein – about 9 grams per bar.
  • E-A-S-Y. Seriously, I can throw these together in 15 minutes or less!
  • Gluten-free and paleo-friendly, with a vegan option.
  • Chocolate. ’Nough said.

Ingredients in Peanut Butter Chocolate Protein Bars

  • medjool dates – you can buy medjool dates that are already pitted or pit them yourself (it’s super easy). Two brands that I like are Natural Delights and Joolies. You can find Natural Delights in the produce section of most grocery stores (near the bananas) and Joolies are offered on Amazon and Thrive Market.
  • peanuts – helps to pack a solid protein punch in these bars.
  • egg white protein powder – collagen and vegan protein powders work too. My favorite vegan brand is Nuzest which is plant-based and has a minimal, clean ingredient list. You can use my code eatingbirdfood for 15% off your order.
  • cocoa powder or cacao powder – either option will work.
  • sea salt – if peanuts are salted, leave this out.
  • dark chocolate chunks or chips – I like to use Lily’s dark chocolate chips to keep this recipe low in sugar and dairy-free.

Notes & Substitutions

Nuts – Allergic to peanuts or prefer a different nut switch up the added nuts and add walnuts, pecans or almonds (or any other type of nut!) to the bars.
Mix-ins – Feel free to get creative with your mix-ins! Coconut would be a great addition.
Balls – if you’re more of a ball type of person, you can absolutely roll them into protein balls – or better yet, try my protein ball recipes!

Benefits of Medjool Dates

Medjool dates are healthy! They contain natural sugar, but they have a low/medium glycemic index score because they also contain a good amount of fiber, which slows the release of the carbohydrates and gives you sustained energy rather than spiking your blood sugar crazy high. They’re also low in fat and packed with nutrients like potassium (50% more potassium by weight than a banana), copper, magnesium, vitamin B6, niacin, calcium, iron and vitamin K.

Peanut Butter Chocolate Protein Bars

These no bake peanut butter chocolate protein bars taste delicious and each bar has 9 grams of protein. Plus, they're so easy to make.
Prep Time: 10 minutes
Resting Time: 30 minutes
Total Time: 40 minutes
Servings: 5


  • 10 pitted medjool dates
  • ½ cup peanuts
  • ½ cup egg white protein powder, collagen and vegan protein powders work too
  • 2 Tablespoons cocoa powder
  • ¼ teaspoon sea salt, if peanuts are salted, leave this out
  • 1-3 Tablespoons of water, if needed
  • 2 Tablespoons dark chocolate chunks or chips


  • Line a loaf pan with parchment paper.
  • Add dates, peanuts, protein powder, cocoa powder and sea salt into the base of your food processor. Process until everything is combined and peanuts are broken down into tiny bits.
  • At this point the mixture might be sticking together well and forming a ball of dough. If so, great! If not, it may be dry and not really sticking together (it will depend on how moist your dates were). If this is the case you’ll want to add a little water. Add 1 Tablespoon, run the food processor and see if the mixture starts holding together. If not, add another tablespoon and blend again. You'll likely only need to add 1-3 Tablespoons of water.
  • Once the mixture is holding together, transfer into the loaf pan lined with parchment. Fold the parchment over top and press the mixture evenly into the pan.
  • Once even, add chocolate chunks and press those into the top of the mixture as well.
  • Place the mixture in the fridge to harden up (about 30 mins to 1 hour) before removing from pan and cutting into 5 bars.
  • Store bars in fridge for up to 1 week. Enjoy cold or at room temperature.



  • Nuts – allergic to peanuts or prefer a different nut? Switch up the added nuts and add walnuts, pecans or almonds (or any other type of nut!) to the bars.
  • Mix-ins – feel free to get creative with your mix-ins! Coconut would be a great addition.
  • Balls – if you prefer balls, you can absolutely roll them into protein balls — or better yet, try my protein balls!

  1. I’ve been on the collagen train lately (I’m not sure if I’m noticing a difference yet, but, like you said, it can’t hurt and it gives me a protein boost so why not), so I was about to comment and ask if collagen powder would work in this recipe when I saw that you had already addressed my question. Like you, I’ve been trying to make more of my own snacks and bars for pre- and post-workout and these look fantastic. I can’t wait to try them!

    1. Yes, one thing to note with using collagen protein powder is to make sure your dates are fresh and not dry because it’s better if you don’t need to add water. If you do add water, the mixture gets super duper sticky.

    1. I haven’t tried it with powdered peanut butter so I’m not sure how much you’d need to use or if it would make it too try. If you experiment with it, let me know!! 🙂

  2. Happy birthday! I have made at home versions of the Chocolate Coconut and the Blueberry RX Bars before but not this variety, looks great!

    1. Would you please share your recipe for the blueberry bars? These are my husbands and they are so hard to find in the town i I’ve in

    1. Hi Elena. I haven’t tried using oats instead of the protein powder, but it should work! Let me know if you try it. 🙂

  3. 5 stars
    I didn’t have peanuts in my cupboard so I replaced these with almonds. It worked and tasted delicious as well.

    1. Hey Karen, To ensure the freshness of these bars I recommend one week in the fridge. If you want them to last longer, you can freeze them and pull them out to the fridge as needed. 🙂

  4. 4 stars
    How much of collagen and protein powder equivalents to 1/2 cup egg white protein powder (collagen and vegan protein powders work too)?

  5. Can I use peanut butter powder in place of the protein powder?
    Also, I have used dried plums (prunes) in place of dates in several similar recipes and the texture was perfect. Do you think the flavor combo would work with these?

    1. Hey Doreen – I haven’t tried dried prunes or peanut butter powder, so I’m not 100% sure how the recipe would turn out. I would imagine it’d be fine, but you’ll have to let me know if you try it and how they turn out!

  6. 5 stars
    Thank you for responding to my question about subbing dried plumbs for dates and peanut butter powder in place of protein powder.
    The bars were great!!
    So glad I made a double batch.
    The texture was perfect, even out of the fridge.
    The bars weren’t too sweet as I used craisins rather than chocolate chips on top(think peanut butter and jelly).
    Next batch I want to use dark chocolate chips.
    Can’t wait!

    1. Yay!! So glad these bars were a hit, Doreen! Thanks for making them and coming back to leave a review. I really appreciate it!
