Why we love this protein bar recipe
When my kids were younger, they played a lot of sports. That means that we were often on the run, so they ate a lot of protein bars.
And of course, each kid had his or her own favorite variety of bar. But all those packaged protein bars have one thing in common: they're crazy expensive.
This recipe for homemade protein bars started out as just a healthy snack that I was just making for my family, and that was that. After much hesitation, I had finally purchased some Vega Essentials protein powder.
I mean, they even sell protein powder at CVS now! I could use a coupon! I was just playing around with it. That's the kind of experimenting I rarely get to do anymore, where I just throw a bit of this and a bit of that into a recipe.
My kids couldn't get enough of these bars. They had even gotten good enough that my husband mentioned them out of the blue one day. I mean, they have the soft texture of a brownie, and they're not too sweet.
“You know, those protein bars were really good.” That's high praise for him. My kids had started asking, “Are those bars hard to make?” That's code for “please make them again.”
I also get “are these bars good for you?” That's also code for “can I eat them all day every day and be healthy?”
They always felt good about these bars because they have the soft texture of a brownie, taste rich and always satisfying. I always felt good about them because they don't have any added sugar, have lots of whole grains, and 13 grams of protein in one small bar.
Plus, I can customize the flavors to suit each individual child's tastes. Now, I mostly make them for my son since he discovered going to the gym and loves the way that makes him look and feel.
Recipe ingredients
There are two main versions of these bars: with dates, and with peanut butter. Most of the ingredients in these bars are the same in both variations, but some are only in one, some only in the other.
In both variations
- Oats: We grind old fashioned oats into oat flour at the start of the process in a large food processor. They add lots of whole grain nutrients and form the backbone of the bars. If you'd rather, you can start with oat flour in the same amount, by weight. For 250 grams of oat flour, if you're measuring by volume, you'd need 2 cups + 1 heaping tablespoon of oat flour.
- Protein powder: This adds a ton of protein to these bars, and adds some flavor if you use a flavored protein powder. If you use a chocolate protein powder, it adds more richness to the bars. If you use whey protein isolate, it has no flavor and adds the most protein by volume.
- Salt: Brightens the flavor of the bars and balances the gentle sweetness.
- Milk: Adds richness and moisture to the bars and helps hold the ingredients together. Add milk slowly because if you add too much, the bars won't set up properly.
- Maple syrup: Adds depth of flavor, sweetness, and helps hold the bars together. You can use another liquid sweetener like honey, but you'll probably need a bit less of it and it will change the flavor.
- Chocolate: Adds flavor, richness, and is largely responsible for helping the bars hold their shape once they set. By using unsweetened chocolate in the bars, they don't add any sugar. First, we melt it, and then it becomes solid again as it cools. If you add the optional chocolate coating to the bars, it adds more flavor and helps hold them together, too. Be sure to use chocolate for coating that has some sugar, or the coating will taste flat and unpleasant.
In only the dates version
- Dates: They hold this version together really well with their stickiness. I prefer Medjool dates because they're stickier and have more of a rich caramel flavor. Deglet Noor dates are smaller, a bit drier, and less sweet.
- Vanilla: Adds more depth of flavor to this version, which has less strong flavors than the nut butter variety.
In only the peanut butter version
- Peanut butter: Always use a “no-stir” type of peanut butter, which is more solid at room temperature than the super drippy natural kind that usually only has the single ingredient (peanuts). You want something that has had some sort of solidifying oil blended into it that will help hold the bars together and keep them from being oily. There are peanut butters like this (I like Skippy brand best), and Barney Butter makes a great no stir gluten free almond butter. I bet Wow Butter would work for a nut-free version.
- Cocoa powder: Adds richness and deep chocolate flavor to the peanut butter bars, and helps mix with the nut butter to provide stability. I prefer Dutch-processed cocoa powder, since it is richer and deeper, but natural cocoa powder works well, too.
How to make homemade protein bars
Process oats, protein powder & add wet ingredients
- Place oats in the bowl of a food processor, and grind them into a powder. If you'd prefer, you can begin with oat flour instead and you won't have to process it.
- Add protein powder, and maple syrup, melted unsweetened chocolate, and milk.
- Add either pitted medjool dates for one variety, or or cocoa powder & nut butter for another.
Process the mixture, & press into a pan
- Process the wet ingredients with the dry just until the mixture holds together.
- Add more milk a little at a time if needed.
- Press everything into a pan, and chill.
Slice the bars, drizzle with chocolate, & serve!
- Once the bars are chilled, slice them into bars with a sharp knife.
- Drizzle with some melted chocolate for extra flavor.
Two recipes, endless options
Have you ever noticed that most of the recipes out there for homemade protein bars are so specific? I am a fan of baking recipes being specific, since baking is chemistry. But these are no-bake.
Those other recipes either rely on one specific type of protein powder, call for a million different funky ingredients I've never heard of, or they are one flavor and one flavor only. So frustrating!
Medjool date version (protein bars without peanut butter)
So I've included two basic recipe formulas for homemade protein bars below. One is made with super soft, packed-with-fiber, deliciously sticky Medjool dates to hold the bars together and sweeten them, of course.
I buy those dates by the pound at Trader Joe's, and I can even find them sold already pitted. Since they're so high in natural sugar, they actually stay for quite a while in the refrigerator. If they seem dried out, just soak them in hot water for about 10 minutes, squeeze out the water, and use the as usual.
You can include unsweetened melted chocolate in the mixture, or not. It really helps the bars hold their shape and gives them a richer flavor.
If you prefer a more neutral-tasting bar, use a vanilla or unflavored protein powder, and leave out the melted chocolate. If you leave out the melted unsweetened chocolate, you will have to add more milk, and the bars will not hold together as firmly when shaped, but the recipe still works.
Nut butter version
But I realize that you may not know where to buy Medjool dates. Or you may think they're too sweet. So I've also formulated another recipe with nut butter and no dates.
I like this version best made with cocoa powder and melted chocolate. I do still include plenty of options for making it more neutral-tasting (including making it with cashew butter).
I've tried these bars with every single variation I recommend. They each work just as well as the other.
Our favorite protein bar variation
My favorite way to make these bars is the “date version.” I always include the melted unsweetened chocolate—and with just a drizzle of melted chocolate on top, at most. You can also add mini chocolate chips to the mixture after you have finished processing it and before you press it into the pan.
Without the full chocolate coating, the bars are much easier to handle and transport. Including the melted chocolate in the bar itself makes the bar richer in taste and more firm for easy handling.
You can use any flavor protein powder you like in the date version and leave out the melted chocolate, and you'll change the flavor profile to suit your tastes. If you have another favorite protein powder, use that!
Recipe tips & tricks
Don't just leave out an ingredient
There are lots of ways to customize these protein bars to your family's tastes and nutritional needs. There's no chemical reaction happening, since these bars are no-bake, so the mixture must have a certain texture right out of the food processor.
We want the bars to hold together well, so you'll need ingredients that provide structure, and ingredients that bind the bars together. Plus, you need a protein powder, since these are protein bars after all!
Don't rush the firming time
These bars will take at least an hour in the refrigerator to become firm enough to slice, and to hold together properly. So don't wait until the moment you need them to make these protein bars! Make a double batch, and stock up, so you and your family are never without this healthy, grab-and-go snack.
Don't add more liquid than the recipe calls for
If you add more maple syrup, or increase the melted chocolate, the protein bar mixture will be overly soft and won't set up.
Popular ingredient substitution suggestions
Dairy free
As written and as long as you use dairy free milk and chocolate, this recipe makes dairy free protein bars.
If you prefer a dairy-containing protein powder, try whey protein. At first I was certain that you did need to include the oats…
Oat-free
I have finally successfully replaced the oats in this recipe, and every other oat-filled recipe on this blog (and in my cookbooks!). You can read all about a potential substitute for oats in baking, and finally make this grain-free!
The TL;DR version for this recipe is that you use wide, flat coconut chips. Since this recipe is no bake, the coconut chips take up a similar amount of space as the oats.
If you're looking for a bite-sized version, try my no-bake protein balls. They don't have protein powder at all, and there's no food processor involved.
You do have to roll all those little bites, but there's a grain free variety in that recipe that you might really love.
Sugar free
The nut butter homemade protein bar variation can be made without added sugars if you replace the maple syrup with Lankato brand maple syrup substitute. You may need a bit less, though, since it's quite sweet. Be sure your nut butter is made without added sugars, too.
Flavor variations
A more neutral-tasting bar
Try using cashew butter as the nut butter for a more neutral flavor that really lets the chocolate flavor shine.
A fruity version
Try replacing the cocoa powder with a freeze-dried fruit powder. You can either buy it as a powder, or buy freeze dried fruit by the bag and grind it into a powder.
If you have a dehydrator, you can make any fruit into a powder. You can also dehydrate fruit on a baking sheet in a 200°F oven for hours. I do not have that sort of patience.
A no-added flavor protein powder version
Instead of protein powder, try using collagen powder for a huge nutritional boost with no added flavor at all. You can use whey protein isolate, like in our gluten free bread flour.
I also really like Vital Proteins Collagen Peptides. That's an affiliate link, feel free to shop around for the best price.
I've also started experimenting with Perfect Hydrolyzed Collagen Peptides (affiliate link), and it's less expensive. I've used that brand in my protein granola, and I might just like it better. Plus, it’s less expensive.
Storage instructions
Refrigerating
I like to keep these bars, usually wrapped individually, in the refrigerator. They're easy to eat chilled without having to let them warm to room temperature.
Freezing
You can freeze these bars for longer storage, but don't try to eat them right out of the freezer! They're too hard to bite after they're fully frozen. Just let them sit for a bit first.
Frequently asked questions
The most time-consuming part of making your own protein bars is washing the food processor! Otherwise, making this recipe is as easy as assembling the simple ingredients, measuring them out, and processing them, which takes about 10 minutes.
Yes! Nature Valley brand makes protein bars that they say are safely gluten free. Be mindful that any of their products with oats may not be made using purity protocol gluten free oats, so whether or not to eat them is a personal decision.
CLIF Kid Z Bars don't appear to contain gluten free ingredients, but their oats are not purity protocol gluten free oats, so I avoid them for my family.
Many Power Bars appear not to contain gluten-containing ingredients, but they seem to be made on shared manufacturing equipment with gluten-containing ingredients.
Yes! If you make the “medjool date” variety homemade protein bar in the recipe below, you won't need any peanut butter at all. If you want to make the nut butter version, use another nut butter like cashew or almond butter, and avoid peanut butter completely.
Did you add any additional liquid? Maybe you added more milk than was strictly necessary. If they aren't setting up, try processing some more oats into a powder, and mixing that with the too-soft protein bar mixture to firm it up.
Interested in getting extra protein?
It seems like anything with the word “protein” in the name is going to cost you top dollar at the store. That's why I love this recipe for homemade protein bars so much: you can make it the way you like it best, and save money in the process!

Hi, I’m Nicole. I create gluten free recipes that really work and taste as good as you remember. No more making separate meals when someone is GF, or buying packaged foods that aren’t good enough to justify the price. At Gluten Free on a Shoestring, “good, for gluten free” just isn’t good enough! Come visit my bio!
Donato Pezzuto says
Been following you and receiving your emails for several months. Thank you for your hard work.
Nicole Hunn says
Thank you so much for the kind words, Donato. I sincerely appreciate it!
Susan says
My granddaughter can’t have oats. What would the best replacement be for these bars?
Nicole Hunn says
Please see the text of the post under the heading “Oat-free, gluten free protein bars”
Tracey Simic says
I just made them using hemp seed instead of pats. Very good. I made the nut version
Emily Olsen says
Thank you! Thank you!
Kathryn Tumbula says
I can’t eat oats. What can I substitute for oats?
Nicole Hunn says
Please see the section of the post titled “Oat-free, gluten free protein bars”
Kate says
Can I use a blender instead of a food processor?
Nicole Hunn says
You can try, Kate, but a blender tends to process too much, too quickly, and tends to create a mixture that’s too soft and too close to liquid.
Jaimy says
I’ve made this several times now and used the blender solely for the oats. Then mixed it in with the dry in a bowl. Then I find mixing the wet ingredients separately, then all of wet and dry together using a hand mixer works really well.
Everything is easy to clean too!
Blue Gantz says
I made them last night. Thanks for the recipe, I think I will make them again to get more dates in since I am in my third trimester and for some reason don’t like dates as much as I usually do. However, I will not put maple syrup in them bc they are tasty but so so sweet.
Deb says
I don’t have a food processor. Do you think I would be able to make this recipe using oat flour instead of rolled oats? Thanks.
Nicole Hunn says
For sure, Deb. Yes.
Rowan says
I’ve started making these every two weeks for most of my breakfasts to get a decent protein boost and I’m not kidding, they’re so much better than off the shelf protein/oat bars/flapjacks. Easy to make (but a bit sticky!) and I only have a small chopper that helps me cut up the dates and blitz the oats. Absolutely awesome.
Nicole Hunn says
I’m so glad to hear that, Rowan. Thank you for letting me know!
Alex says
Can you use dates AND peanut butter?
Nicole Hunn says
I haven’t tried that, Alex, as the proportions of the ingredients in each version are different. You could try, but you’d have to experiment, and I’m afraid i can’t promise results. So sorry!
Angela Smith says
Hi Alex i do dates and peanut butter in my bars. Just experiement:)
Paige says
Hi! I made these for the first time the other day and they turned out delicious! But I’d love if they had some more crunch/texture in them (thoughts about chia/nuts?)… in addition I’d love to find a way to make them be able to sit out for at least 24 hours so I can tuck them in my locker at work for the day.
Any ideas?
Nicole Hunn says
I’d be afraid that adding mix-ins that are crunchy to these bars would make them fragile, Paige. And you can wrap them tightly (I really like Glad Press n Seal wrap) and they’ll be fine to sit out for a bit.
Bill Chee says
What can be substituted for the milk to make it non-dairy.
Nicole Hunn says
Please see the section of the blog post entitled “substitutions” which talks specifically about dairy free protein bars.
Emma says
Are both the date and nut butter bars 288 cals? I see that in the nutrition facts but I was just wondering if it was the same for both bars. Thanks!
Nicole Hunn says
As the notes indicate, Emma, the nutrition information is only for the nut butter bars. If you’d like the info for the other version, you’ll have to use a nutrition calculator.
Barb says
Hi there! Any suggestions on what I could substitute for oats? They are never ok for my body. Thanks!
Nicole Hunn says
Please see the Substitutions information in the text of the post, Barb. All the information is there already.
Nancy H says
Just made the date version, minus the last optional chocolate dip (I did incorporate the 3oz melted chocolate). The bars are amazing. I would highly recommend. Clean-up wasn’t too bad (got a new food processor in the last few months). Question: I love using dates, but I also love PB. Any advice on a combo of the 2 versions? Also tips for extra add-ins like hemp/chia/flax? I don’t want to get too crazy but I have so many things at home to use up. Thank you for sharing this recipe.
Nicole Hunn says
Hi, Nancy, I’m afraid I don’t recommend adding whatever else you have on hand, no. These are quite flexible, but I never recommend using ingredients just to use them up. I do have a recipe for chocolate chia pudding that you might like, and I use chia seeds in my overnight oats to help thicken them. To make a PB/date version, you could try replacing some of the ground oats with PB2, but I’ve never tried that so I can’t promise results.
David B says
I am having trouble finding dairy-free chocolate, so I am wondering, could I use either carob chips or carob power in this recipe? If so, if I use the chips would I use 1:1?…what if I used powder? I would assume I would need to add additional liquid?
Thank you
Nicole Hunn says
I’m afraid I can’t advise you on how to use carob, since I don’t have any experience with it at all. Much of Scharffen Berger chocolate is dairy free, as is some Baker’s brand chocolate. I’d stick with dairy free chocolate, not carob.
C4 says
I made the peanut butter version using Teddy peanut butter and unsweetened vanilla almond milk and they turned out great. You are definitely on point with the food processor cleanup. That was brutal but totally worth it.
Nicole Hunn says
Hahaha it’s the little crevices in the blade of the food processor that get me every time! I just looked up Teddie peanut butter, and now I wonder why I’ve never seen it before. It looks good, so thanks for the tip, C4!
