The fact that these low-carb peanut butter chocolate chip bars are also fuss-free means you can enjoy them quickly. They are packed with flavor yet manage also to be sugar-free, grain-free, gluten-free, and low in carbs.
I’ve always been a fan of the flavor of chocolate and peanut butter together. I don’t know who was the first to pair them, but as far as I am concerned, it was a genius moment.
Being a lover of this combo means that this girl is not about to stop putting them together just because I’m on a ketogenic diet.
You see, I’m on a quest to show the world that the keto lifestyle is not only doable, but can also be a delicious way of eating.
This recipe was inspired by my well-loved keto soft-baked chocolate chip bars, so think of these as my peanut butter version.
You might also want to try my keto peanut butter fat bombs if like me you can’t get enough of this flavor profile. They taste just like Reese’s peanut butter cups and require no baking.
See there, I’m giving you plenty of delicious choices.

Keto Peanut Butter Chocolate Chip Bars
I am a fan of creating baking recipes that are easy. In fact, my keto baking aims to keep things so simple that even a novice baker can duplicate with success.
So if your schedule is anything like mine, you will appreciate that my recipes aren’t overly complicated and use easy-to-come-by ingredients.
The best way I can describe these bars is that they start as keto blondies and then get a generous dose of chocolate and peanut butter.
To ensure that each bite had an abundance of this flavor combo, I added peanut butter to the batter and dotted the top of the bars with 1/2 teaspoons of peanut butter.
And because I can’t leave good enough alone, I also sprinkled dry roasted peanuts across the top before baking and then amplified the chocolate flavor by using both sugar-free chocolate chips and chocolate bar pieces.

How To Make Low Carb Peanut Butter Chocolate Chip Bars
I have a confession to make, you see although I love to bake keto cookies, I am still a little more partial to cookie bar recipes during busy seasons. Why? Because they are so much easier to execute.
To be honest, I would much rather spread and bake a batch of bars than make a bunch of individual cookies when pressed for time. It’s definitely one more reason to make it part of your keto baking rotation.

The following are all the ingredients you’ll need to make these keto peanut butter chocolate chip bars:
Note that the full printable recipe card is at the bottom of this page. But I recommend you stick around to get all the details before attempting this recipe to ensure great results.
- Sugar-free all-natural no-stir peanut butter
- Unsalted butter, room temperature
- Eggs
- Granulated sugar-substitute
- Sugar-free chocolate chips
- Sugar-free chocolate bar pieces
- Salted dry-roasted peanuts
- Baking powder
- Sea salt

Peanut Butter Swaps
This recipe uses unsweetened, natural no-stir peanut butter. Regular peanut butter is loaded with sugar and it’s why it’s so high in carbs but when you use a natural one the carbs stay reasonable.
I went for a stir-free option for ease. But I’m not saying you can’t use the kind you need to stir. However, if you go this route, you will need to make sure it’s well mixed before using it in this recipe.
With that being said, you can easily swap the peanut butter for almond butter, sunflower seed butter, cashew butter, macadamia nut butter.
Sweetener Options
When it comes to choosing which sugar substitute to use for these keto peanut butter chocolate chip bars I have a few options for you to choose from.
My go-to choice is Lakanto Monk Fruit because the texture is spot on since there is barely any aftertaste. It is a monk fruit and erythritol blend.
Lakanto Monk Fruit gets its sweetness from antioxidants called mogrosides, instead of fructose or sucrose. It’s why it’s a great all-natural sugar substitute and has zero calories and zero glycemic indexes.
I’m also partial to Swerve an erythritol blend. Unlike other natural sweeteners like stevia, it has no bitter aftertaste and measures just like sugar.

The Importance Of Choosing Your Sugar-substitute Wisely
It’s also a sugar substitute that browns and caramelizes just like sugar. Swerve is made from ingredients found in select fruits and starchy root vegetables and contains no artificial ingredients, preservatives, or flavors.
Plus, it’s unlike other sugar alcohols because it has a 0 % impact on blood sugar.
You could also use the stevia and erythritol-based brand Pyure for most of my baked goods. But if using Pyure you will want to use 1/2 the amount called for in this recipe since it’s much sweeter.
I wouldn’t attempt to make it with a straight stevia baking sweetener unless you are already familiar with it. Personally. I don’t ever recommend stevia alone in my recipes because, depending on the brand, they may be quite bitter.
Lastly, if you can’t easily find a more natural sugar substitute, you can also use Splenda with great success. In this case, you will want to use the Splenda that has a bulking agent. It’s the one that comes in larger bags.
I don’t advise using Splenda Bake because it’s actually half sugar, half sucralose product and will be too high in carbs to be considered low carb.
This recipe does not call for a brown sugar substitute like Lakanto Gold or Surkin Gold, although it would have also worked. I chose just to use a granulated sugar substitute to keep things easier but swapping 1/2 of the sweetener for a brown sugar substitute is doable.

Why can’t you freeze these longer?

Hi Paula, You certainly freeze longer but I just find the flavor diminishes a bit if frozen too long.

I’d love to give these a shot! They look amazing! I was wondering if you think it would work to leave out the chocolate chips and roasted peanuts as topping? As in just making the base batter without layering anything on top. I’d love to hear your thoughts or opinion. Thanks so much!

Just made these today and they are delicious! Mine did turn out a bit fluffier and thicker than what you show in your pics, but still delicious nonetheless!

Hi Kristine, The differences in oven can sometimes be the reason and or the pan. You might want to bake yours in a larger pan next time. Glad they still tasted yummy for you.
