Homemade keto protein bars that taste like pecan pie! You simply can’t go wrong with a healthy no-bake energy bar, filled with healthy fats and collagen protein. They are so easy to make and have less than 2g net carbs per serving.
I used to be a real sucker for protein bars. Back when I worked in higher education administration, I usually had a drawer full of Luna Bars. And the pecan pie flavor was one of my favourites. Because if you know anything about me, you know I love me some pecan pie.
Now, of course, I favor keto pecan pie recipes, such as my classic Keto Pecan Pie, and my beloved Keto Chocolate Pecan Pie Muffins. But back in the day, I loved the pecan pie Luna Bars.
I thought I was doing something good for my body back then. It kind of blows my mind to think about it now. I shudder to think what was in them. Oats, sugar, soy, brown rice syrup. Things I wouldn’t dream of eating anymore.
And now I look at the exploding keto protein bar industry, which is surely in the many millions of dollars. I do understand the appeal of these easy keto snacks, for times when you’re on the go or just too busy to make something yourself. And there are some very tasty ones out there. But it’s quite a racket, when you think about it.
They are all wildly expensive, most of them costing at least $30 for a pack of 12. And a number of them contain rather questionable ingredients – no one is regulating the use of the term “keto” and there are quite a few that really aren’t keto-friendly. So be forewarned!
Why not make your own Keto Protein Bars?
I do keep some Perfect Keto bars on hand for travel or snack emergencies, but on the whole, I just don’t recommend making them a daily habit. The cost is just too prohibitive. And making your own protein bars means you know exactly how keto friendly they are.
It’s a lot easier than you think! Check out my video to see how quickly you can make these bars at home.
I created these Pecan Pie Energy Bars for my Easy Keto Breakfasts book. They honestly take about 15 minutes to make, although you do need to chill them for a while before you can dig in.
But the price is right, my friends. The recipe makes 10 bars, and each has only 4.5g TOTAL carbs. And more than half of that is fiber, so the net carbs are less than 2g.
Also if you account for the fact that all of your ingredients will last you much longer than this one recipe, the total price for 10 bars comes out to about $12. That’s a far sight better than $30 for 12!
There is also nothing in them that will go bad very quickly so they are shelf stable for at least a week, if not two. Now, I do admit that they are a bit fragile at room temperature. But if you pop them into a rigid container, you can take them on the go with you just about anywhere.
Best of all? I swear the flavor beats the pants off any purchased keto bars I’ve tried.
Tips for Making Keto Pecan Pie Energy Bars
These are so simple to make, you won’t even believe it. Here are my best tricks for making these easy keto energy snacks:
Toast your pecans first: Toasting brings out the natural sweetness and intensity of the nuts. I like to toast mine in the oven at 350F for about 10 minutes. You can also toast them in a skillet over medium heat. No matter which way you do it, stay nearby and watch them carefully. Pecans can burn quickly when you’re not paying attention.
Grind the pecan finely: A food processor works best for this and you really want to take it to the point that they resemble crumbs. If they aren’t finely ground, your bars won’t stick together that well.
Use a powdered sweetener: Because these aren’t baked at all, you don’t want to use a granular sweetener – they will be far too gritty. I used Swerve Confectioners for mine.
Add collagen peptides: Collagen is a great source of protein and is said to be very good for our hair and joints, especially as we age. But I add it to these energy bars in part because it helps them stick together better. Since they require no baking, you need a little extra “glue” to hold them together.
I used unflavored collagen from Primal Kitchen but it just occurred to me that the Salted Caramel collagen from Perfect Keto would be DREAMY in these bars.
Work the melted butter in well: Once your dry ingredients are whisked together, you simply add melted butter and the extract. But you really need to work it into the dry ingredients until they begin to stick together. I find this works best with a silicone spatula, so I can really mix it hard against the bowl.
Use caramel flavor: If you can find it, use a caramel extract or flavoring for a more pecan pie-like flavor. Vanilla works well too, though. As you can see in the video, I ran out of caramel extract so I used maple. Because maple and pecans are great together too!
Line the pan with parchment: This allows for easy removal and cutting, once the bars are chilled. You can simply lift the whole thing out of the pan and cut with a sharp knife.
Press the bars in firmly: Don’t be afraid to use a little force here. You really want to press them in as firmly as you can, so that they stick together well.
See how easy it is to make your own keto protein bars? It really takes almost no time at all and you know EXACTLY what’s in them and just how keto-friendly they are!

Can different nuts be substituted for the protein bars? Many thanks
I would think so. I haven’t made this recipe in a while and it does need some updating but fee free to experiment!
I love these. but not a fan of swerve and erythritol. Will the Monk allulose powdered work the same?
These were really good, very nice salty/sweet combo. I didn’t have almond flour so I used flaxseed meal as a 1:1 replacement which worked well. I love Carolyn’s high protein recipes because I don’t even taste the collagen!
Can Isopure protein powder be used as a replacement for collagen?
Sure, but it won’t help them hold together as well.
Would Pecan flour work instead of pecan crumbs?
It’s a lot more dry so I am not sure it will hold together well.
These are wonderful! A perfect snack.
Thanks for this. I’ve been looking for protein bar recipes and this one intrigues me but I am allergic to pecans, walnuts, hazelnuts and the like. Not all nuts, just specific ones (sesame too – I know it’s not a nut). An odd collection of allergies. Is this doable with almonds?
Yes, I think it would be. Just really make sure those almonds are well ground and then add more almond flour.
Thank you for the quick response! I’ll let you know how they turn out.
Cheers!
Delicious! I used vanilla extract and drizzled some sugar-free maple syrup into the mix to give a little caramel flavor. I ran out of almond flour, so just whizzed some almonds in my food processor to make some. Wow! Fit perfectly in the little pan that came with my toaster.
I’m struggling to get in enough protein each day. I literally have no appetite. I saw these and thought they might be the answer!
I looked through the recipe twice and didn’t see (very possible I missed it) how many grams of protein per bar?
Oh goodness! I just found it! 8.8. Sorry!
