Easy Keto Peanut Butter Bars

low carb Keto Peanut Butter Bars

My recipe for Keto Peanut Butter Bars is full of peanut butter goodness. It’s a recipe inspired by the one I would make often for my family before I made keto a lifestyle. The recipe is easy and delicious making it a fuss-free option.

I have always enjoyed the flavor of peanut butter and if it was slipped inside a cookie or bar then even more so. This recipe for keto peanut butter bars makes a healthy low carb option that you’ll find yourself turning to often.

What’s more this recipe for low carb peanut butter bars is so good that even those not on a keto diet will enjoy. Don’t you just love giving your family healthy treats that they will actually ask for?

Keto Peanut Butter Bars

To make these keto peanut butter bars you’ll need a few basic keto baking ingredients. My recipe includes creamy peanut butter, eggs, butter, almond flour, and a little whey protein.

Don’t have any whey protein available? No problem you can make substitute it for more almond flour. I told you these were simple.

I have a recipe for Keto peanut butter cookies that my family and friends also enjoy but the convenience of cookie bars can’t be beaten. I also have a complete list of Keto Cookies that any cookie lover doing keto would enjoy exploring. 

Don’t get me wrong I love me some keto cookies, but it’s so easy to just mix up a batch of keto cookie dough and bake in a  pan and then cut into squares.

Back when I used to create regular peanut butter bars, I used to do so with my eyes closed. Well, that’s what this low carb peanut butter bar recipe offers.

You can, of course, substitute the peanut butter for your favorite nut butter and still have an amazing keto treat. See there I just gave you more options!

Have you ever found yourself craving for a season to already get here? Well, that’s what birthed these keto peanut butter bars.

It’s September and the weather should be pointing to the fall season. Well, here in South Florida, we ain’t about that. We’ve been experiencing 90 degree days, with the humidity feeling like 1000 percent.

The fall season seems like a fantasy in my neck of the woods.

I’m not completely sure why fall is my favorite season, especially since it’s really non-existent here. And here is where I’ve lived most of my life.

Despite this, I still love everything about what the fall season represents. You know the start of a new school year, pumpkin latte, coming up with a keto peanut butter bar recipe and even the cheesy fake fall leaves in the department stores.

I did warn you that I LOVED everything about this season.

For some reason, I associate peanut butter also with the fall season. Again, maybe it’s about all those peanut butter and jelly sandwiches I had as a kid at school.

All I know is that my craving for peanut butter is what brought this recipe to light.

New Beginnings

Perhaps, it’s the idea of fresh starts that grabs at my heart?  You see in the Jewish calendar, September marks the beginning of a New Year. As a Christian, I guess in some ways I am drawn to this instinctively after all my Lord is a Jew.

Recently, I realized that I do what most people call “spring cleaning” during the month of September.  It’s something I’ve been doing for years. Sure I also do the traditional spring cleaning but for some reason, I feel this urgent pull to do the same in the month of September.

Am I the only one who goes through this?

Making Room For Blessings

For the past few weeks, I have been getting rid of a lot of unnecessary things, organizing what I want to keep. And doing a lot of redecorating.

I must admit I am enjoying every second of the process. My family? Probably not so much, since I tend to disrupt the peace with my desire to get everything just right.

During this month I also tend to do a lot of soul-searching, making sure that my heart is in the right place. I re-evaluate the goals I set in January and determine if any changes need to be made.

Fall is a season I look forward to for all these reasons and more, even if I don’t get to see the turning of leaves or cool breezes.

So how do I celebrate fall in South Florida? Well, it usually involves baking something that brings the scent of the season into my home.

Does it mean I will probably be doing so with my air-conditioner on blast? That’s a given, but it will not deter me from celebrating fall in Miami.

I have several low carb keto recipes that are considered fall recipes. I thought I would share just a few to assure you that my love of everything fall is genuine.

How about you? What’s your favorite season of the year? Why do you think you’re drawn to it?

  1. Does it matter which type of whey protein - isolate, concentrate, casein or a combination of someall? I find ones containing casein tend to be less dry. Nice recipe!
  2. leonie hansen
    Thanks for some yummy recipees i am going to try and share with my friends. Keep up the great work God Bless
  3. Hi Joy, I've updated the recipe and added the pan size.Thanks for stopping by and making be aware.
  4. Can I use Splenda for the sweetener?
  5. I didn't see where the sour cream was put in the recipe, does it go in and when?
  6. Hi, when do you add the sour cream?
  7. Hi how much vanilla extract and when?
  8. Hi, thank you. I made this and the resulting volume wouldn't fit in an 8 X 8 pan. I got it in a 9 X 12 pan and it barely fit, took a really long time to back and turned out like cake....a very yummy cake but cake nonetheless. Yhoughts? Suggestions?
    • Hi Marnie, Not sure why it turned out more like a cake darling but I went ahead an updated the recipe to use a 12x12 pan. Perhaps the pictured pan I used was a little bigger since it was a disposable pan. The recipe is a couple of years old and although I wrote that pan size I may have been mistaken. Thanks
  9. Jejejej your’e too cute Jenny. Enjoy in good health Darling.
  10. Well, Im back. I just had to make another because my non-keto hubby gobbled it all up! I used a 13x9 pan this time, perfect size, and this is still a nice big cake/bar with a fabulous non-crumbly soft texture. It is the best Keto baked good I have made in a year. Love this recipe so much.
  11. At the top of the recipe under the title you give a baking time of 35 minutes and In #8 of Instructions you say bake for about 1 hour. So I can set my timer which one is correct?
  12. I tried these and like them very much. I was wondering if anyone tried making them without peanut butter for variety? Plain vanilla or maybe with cocoa and nuts. I’d love to hear how they turned out.
