These homemade protein bars are no-bake, endlessly customizable energy bars. Just like Luna and Power bars, and made with your favorite protein powder.
This recipe is not like those other fussy, confusing recipes out there!
How homemade, gluten free protein bars came to be
My kids play a lot of sports. That means that we're often on the run, so they eat a lot of protein bars.
And of course, each kid has 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 something 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. Very few notes, even fewer apologies.
These gluten free protein bars were better than packaged protein bars
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.
“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.”
They have the soft texture of a brownie, and they're not too sweet. For something more cookie-like, give my classic protein cookies or my peanut butter protein cookies a try. :)
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?” I also get the same sort of questions when I make my protein pancakes!
Why these gluten free protein bars are the best (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
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 they're essential for recipes like my healthy Paleo fudge. 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.
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 one another.
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.
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!
Tips for making the best homemade high protein bars
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.
Gluten free protein bars: substitutions
Dairy free protein bars
As written and as long as you use dairy free chocolate, this recipe makes dairy free protein bars.
If you prefer a dairy protein powder, try whey protein. For now, yes, you do need to include the oats. There's no substitute!
Oat-free, gluten free protein bars
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 how to substitute oats in the gluten free 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 peanut butter energy bites. They don't have protein powder at all, and there's no food processor involved.
You do have to roll all those little bites, though. :) There's a grain-free version, too!
Sugar free, gluten free protein bars
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.
DIY protein bars: flavor variations
A more neutral flavor
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 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.
Storing your gluten free, high protein bars
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.
FAQs
How long does it take to make your own protein bars?
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.
Are Nature Valley protein bars gluten free?
Yes! Nature Valley brand makes protein bars that they say are safely gluten free. I would avoid any of their products with oats, though, as it doesn't appear that they use purity protocol gluten free oats.
Are Z Bars gluten free?
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.
Are Power Bars gluten free?
Many Power Bars appear not to contain gluten-containing ingredients, but they seem to be made on shared manufacturing equipment with gluten-containing ingredients.
Can I make homemade protein bars without peanut butter?
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.

Kim Key says
How many calories and how much protein per bar?
Nicole Hunn says
I don’t have that information, Kim, but you can feel free to plug your ingredients into an online nutrition calculator!
Thomas says
These bars are perfect. The recipe is so simple compared to others out there, but flexible enough to allow for different flavor options. I love the nut butter version (with the cocoa powder & melted chocolate). Dates aren’t a staple in our pantry, but I might have to get some just for these bars… and maybe some of that Paleo fudge too. :) Thanks!
Nicole Hunn says
So glad you’re enjoying the bars, and the flexibility of the recipe, Thomas!
Ruth says
Looks good but wonder what the nutritional breakdown is? Calories?
Nicole Hunn says
I don’t generally provide nutrition information, Ruth. Feel free to plug the ingredients into an online nutrition calculator for the same approximate type of information I’d be able to provide you.
Carol Groat says
My goodness these are delicious, Made the date free recipe! I make a lot of your recipes but rarely comment! The texture is perfect. I’m excited for the whole family to try them out!
Nicole Hunn says
I’m glad you were moved to comment, Carol! So glad you are enjoying this simple, versatile recipe. I hope your whole family loves them, but not too much that you don’t get any. :)
Debbie T. says
LAST question: can I use 3 oz. of melted 70% dark chocolate instead of unsweetened chocolate in the bars?
Nicole Hunn says
Sure, Debbie, you can use dark chocolate in place of unsweetened chocolate. The result will just be sweeter. The reverse is rarely true (that you can use unsweetened in place of dark), but you can almost always use 70% dark in place of unsweetened. Enjoy the bars!
Debbie T. says
Hi Nicole,
I only have a 4-cup food processor. If I use oat flour instead of oatmeal I would simply weigh out 250g of flour, correct? Can’t wait to try this!
Nicole Hunn says
Hi, Debbie, yes you can use oat flour in place of whole oats, by weight, just as you say. :)
Ioannis says
Hello , do you have the nutritional value table for this one ?
Nicole Hunn says
I don’t, no, Ioannis. Feel free to plug the ingredients into an online nutritional calculator, though. Just be sure to include only those ingredients that you choose to use.
Amanda says
Do you think I could swap honey for the maple syrup? I don’t like the flavor of it. I know… I’m weird. Haha
Nicole Hunn says
Hi, Amanda, honey is thicker than maple syrup, so you’ll need more of it to moisten everything. I know that honey and maple syrup are often thought of as interchangeable, but they’re really not exactly the same in viscosity. Hope that helps!
Felicia says
Can I use organic oat flour instead of grounding the rolled oats? If I use the oat flour do I need to bake it.
Thanks!
Nicole Hunn says
Hi, Felicia, sure, you can definitely use oat flour instead. And no, you don’t need to bake the bars at all, either way. If you’d like to deepen the flavor of the oat flour, you can try ‘toasting’ it in a 250°F oven in a thin layer on a baking sheet for a few minutes, or until just becoming fragrant. I hope that helps!
Felicia says
I love this recipe. I made the nut butter version (almond butter) and used organic oat flour. Also because I am trying to cut out sugar so I used dates and food processed it with water to form a paste. Taste so good.
Nicole Hunn says
The best part about this recipe is how much you really can make it your own, Felicia!
Stephanie says
Hi, do you know if it would be possible to use prunes, or raisins, instead of the dates?
Thanks!
Nicole Hunn says
Hi, Stephanie, Prunes have more moisture than dates, so your bars would likely be considerably less firm. You could try using less maple syrup and/or adding more oats/oat flour to compensate. Worth a try!
Richard Whyte says
make sure you have a quality food processor, I attempted to use my ninja blender and it turned into a big mess and a nightmare. My mistake
Maria says
Me too. I can’t tolerant oats. Would rice flakes or buckwheat flakes work?
Nicole Hunn says
I’m afraid I don’t know, Maria. Feel free to experiment!
Terry Lamoureux says
Have you considered trying this recipe with quinoa flakes? They are similar in texture and taste to oats and I have used them to replace oats in my oatmeal cookie recipe. (I have a problem with oats, gluten free or not).
Terry
Nicole Hunn says
I haven’t Terry, but I have baked with quinoa flakes. They might work in this recipe, but I’m afraid I’m not very optimistic unless you make other modifications, basically turning it into a new recipe. Quinoa flakes are very soft, and not chewy. Oats are much more substantial and chewy.
Erin says
Hi! Do you gave nutritional information, depending on each bar size? Thanks!!
Nicole Hunn says
I don’t provide nutritional information, Erin, but feel free to plug the ingredients into an online recipe calculator. That’s all I would do anyway!
Rensing says
Greetings from Singapore! Juz made this n they r super yummo. Kids tested n approved!! Thanks much!
Nicole Hunn says
So glad, Rensing! Thanks for letting me know. :)
Julie Cataline says
Can I use deglet dates in place of the medjool?
Nicole Hunn says
Hi, Julie,
Definitely. They’re slightly less sweet and a little less sticky, so just watch for the proper consistency as described in the recipe. :)
Deb says
Sounds wonderful! Have you tried to add cranberries or coconut flakes?
Nicole Hunn says
I haven’t, Deb. You might be able to add some coconut flakes in place of some of the oats, and some dried cranberries in place of some of the dates. Since these aren’t baked, it’s all about the consistency so it holds together properly.
Jennifer S. says
Oh boy – can’t wait to make these babies!!
loussin says
Just made the nut protein bar, its delicious. is there any was we can have the nutrition value ?
Nicole Hunn says
I’m afraid I don’t provide nutrition information loussin, but feel free to use one of the online calculators. That’s all I’d do!
Kathi Robards says
Are the Trader Joe’s Medjool Dates really gluten free? I haven’t been able to confirm that.
Nicole Hunn says
Since they’re a single ingredient, Kathi, and there is no allergen warning on the label, I use them. If you’re at all concerned, definitely submit a question through their website. I’ve done that before and they always provide good information in response.
Jennie says
Yes, me too. I don’t think we have gluten-free oats available in Australia.
josie says
yes we do hard to find but specialty health food stores do sell them
Josie says
if your from Sydney MR VITEMINS @ chatswood
Victoria Donaldson says
They can be found in some chemist warehouses or on chemist warehouse online. A little ex’y but worth it if you want to try stuff like this.
Laura E says
I, too, would like to see a version without oats – they do not sit well with me at all.
Nicole Hunn says
Working on it, Laura!
Angela Gallant says
I would love to see grain free. I wonder if buckwheat would work as well as oats. I am allergic to all grass grains…which includes oats. Usually, that means GF will work for me. But even GF oats is a no go.
K Yankovich says
Are any major brands of oats (in normal grocery stores) gluten-free?
Faith says
I find Bob’s Red Mill certified gluten free oats in most major grocery stores now. The come in both quick oats or rolled oats. Depending on the store, it may be in a separate gluten free section or with the organic section. The other brands you usually see, like Quaker, etc. are not g.f.
Laurie says
BTW, Quaker recently released GF oats and I’ve found them in my local grocery stores in Southern California. Trader Joe’s GF oats is still the one I purchase the most.
Anita Guns says
Unfortunately oats contain AVENIN – a gluten like protein that some can tolerate – others like me cannot. It cannot be processed or cooked out. It is disappointing so many recipes call for oats – I try the quinoa substitution but it does not always work!
Mare Masterson says
Looking forward to the grain free versions!
