Have you ever had the munchies, opened your pantry to peruse the options, then realized every item on the shelves is either in a shiny wrapper or cardboard box? That’s been me for the last two months. No more! I’m taking back my breakfasts and snacks with these Peanut Butter Protein Bars.

Soft and chewy homemade Peanut Butter Protein Bars with simple ingredients like oatmeal, honey, chocolate chips, and protein powder. No bake, healthy, and way better tasting than store bought!

Made with oatmeal, protein powder, honey, and some chocolate for happy measure, these healthy oatmeal protein bars are no bake, and the only equipment you’ll need is a bowl and a spoon.

With the all-out crazy of the last few months (hi, holidays, travel, and general cookbook mania), I’ve been relying on more store-bought snacks than usual. While they certainly have their place, I’ve missed my homemade healthy snacks.

One of the shiny wrapper foods I’ve been relying on the most these past few months is protein bars.

Yes, a store-bought bar will do in a pinch, and I appreciate the larger selection of healthy, high-protein options that are on the market now, but nothing feels or tastes as wonderful as making your own wholesome snacks from scratch.

I love knowing exactly what is in these homemade chocolate peanut butter protein bars.

Plus, just like these no bake Protein Balls, the ingredients are simple and nourishing, and the cost-per-bar is a fraction of the ones at the store.

Also, SO YUMMY. The texture of these bars is soft and chewy, and they taste like a thick, bakery-style peanut butter cookie.

Peanut Butter Protein Bars. Soft, chewy, and made with wholesome ingredients.

As an even-better bonus, these no bake Peanut Butter Protein Bars can be stored at room temperature, something you usually only see in a baked protein bar recipe.

That means they are travel friendly and easy to keep at your desk, and you can tuck them in your gym bag for a post-workout refuel.

How to Make Peanut Butter Protein Bars

The ingredient list is short, simple, and a slam dunk.

  • Peanut Butter. Healthy fats, protein, and the all-out delicious factor. You can use any kind you like, be it shelf stable or drippy peanut butter.

The consistency of your batter can vary based on the type of peanut butter you use. If your batter is looser than you would like, simply add an extra tablespoon or two of oats until it holds together.

  • Oatmeal. Rolled oats are hearty, rich in fiber, and give the Peanut Butter Protein Bars their structure.
  • Honey. For its natural sweetness and “glue” factor.
  • Protein Powder. Pump ’em up! To make these protein bars with protein powder, stir in 1/2 cup (about 2 generous scoops) of your favorite brand of protein powder. You can use whey- or plant-based protein. I recommend vanilla, though I suspect chocolate would be tasty too.
  • Flaxseed Meal. Omega-3s please.
  • Coconut Oil. To help the bars bind and solidify.
  • Cinnamon and Chocolate Chips. No ho-hum bars here. These Peanut Butter Protein Bars are loaded with the good stuff.
Peanut Butter Protein Bars. An easy, no bake snack the whole family will love.

Once you have the ingredients, it’s as simple as stirring. These healthy oatmeal protein bars are made in one bowl.

Press your bar “batter” into the pan, pop them into the fridge, and they’ll set within an hour.

How to Store and Freeze These Protein Bars

  • To Store. Store the bars at room temperature for up to 1 week. You can also store them in the fridge, though I find they taste best at room temperature.
  • To Freeze. Place bars in an airtight freezer-safe storage container and freeze for up to 3 months. I like to wrap mine individually, then remove them from the freezer as needed.
Chewy Peanut Butter Protein Bars. A protein-packed snack that's gluten free.

Soft and chewy homemade Peanut Butter Protein Bars with oatmeal, honey, chocolate, and protein powder. No bake, healthy, and way better than store bought!

Prep: 15 mins
Cook: 1 hr
Total: 1 hr 15 mins

Servings: 12 bars



  • Line an 8×8- or 9×9-inch baking pan with parchment paper, leaving overhang on two sides like handles.
  • Place the peanut butter, honey, and coconut oil in a medium heatproof bowl. Set the bowl over a saucepan of water and bring the water to a simmer over medium to medium-high heat. (Do not let the water boil, and make sure the water does not touch the bottom of the mixing bowl.) Stir and heat until the mixture is smoothly combined. Remove the bowl from the saucepan and turn off the heat.
  • To the bowl with the peanut butter mixture, add the oats, protein powder, flaxseed, cinnamon, and salt. Stir to combine. The mixture will seem very dry at first but will come together as you stir. It won’t be sticky but should hold together when pressed (see recipe notes for more details). If the mixture is still fairly warm, pop the bowl into the refrigerator for a few minutes to let it cool, then stir in the chocolate chips. (Cooling the mixture will prevent the chocolate from melting. Don’t worry if they do melt a little—the bars will still be delicious!) Press evenly into the prepared pan and refrigerate for 1 hour or until firm.
  • Lift the bars from the pan using the parchment handles and transfer to a cutting board. Slice into bars of desired size and enjoy.


  • *The consistency of the bars will vary based on the brand of peanut butter you use. If they seem too loose, add a tablespoon or two of extra oats. If they seem too dry, add additional peanut butter, honey, or even water, 1 tablespoon at a time, until the bars hold together easily when pressed into the pan.
  • The nutritional information will vary based upon the brand of protein powder you use. If you’d like to calc them with a specific brand, you can do so for free at myfitnesspal.com.
  • Store the bars at room temperature for up to 1 week or freeze for up to 3 months.
  • I like to wrap mine individually, then remove them from the freezer as needed. You can also store them in the fridge, though I find they taste best at room temperature.

  1. This recipe reads lovely and the comments come through. Could you recommend another type of oil? I am highly allergic to coconuts but would love to try these! Thanks!

    1. Hi Nicole, I’ve only tested the recipe as written, but you could probably use any oil that works for you.

  2. I’m wondering why the recipe calls for the addition of coconut oil when natural peanut butter is so oily to begin with. And specifically, coconut oil, although featuring in healthy recipes, is highly saturated and appears to raise cholesterol levels (though some studies point to it lowering LDL).
    Is the additional oil necessary? Thanks!

    1. Hi Nicky! This is how I’ve tested the recipe multiple times and works well for me. If you decide to play around with the recipe to suit your own needs, I’d love to hear how it goes.

    2. Nicky,
      I’ve made these without the coconut oil. The first time subbed some Irish butter for it. Yum! Since then, I didn’t substitute, I just eliminated. It needed a bit more water that I added a bit at a time. Still absolutely delicious.5 stars

  3. This is a great recipe that my teenage son loves. After making it a few times I made a small change to mix it up and used 1C oats and 1 C Rice Crispy’s. It adds a nice crunch to the bars!5 stars

  4. I did try using a lovely museli mix instead of just the oats and it was too wet, although it does taste amazing. It bound together and cut very well, just melts quickly. Next time I will add more plain oats to correct the proportions to be inline with the recipe. Thanks for your efforts in creating healthy options.

  5. These are the best! A true winner when everyone in the family enjoys them. Great for lunchbox snacks.5 stars
