This recipe for low-carb peanut butter chocolate chip bars is fuss-free, so you can enjoy them quickly. They are packed with flavor yet manage 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.

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 it 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 a little more 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.

The best part is that these cookie bars clock in at only 3.1 g net carbs per serving!

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 bar cookies 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.

Thankfully, making this cookie bar recipe is pretty straightforward.

Begin by preheating the oven to 350 degrees and lightly greasing a 9×13 baking pan with butter or coconut oil.

Then, I use an electric mixer to beat together the butter, cream cheese, creamy peanut butter, vanilla extract, and sugar substitute in a large bowl.

After that, I add the eggs, one at a time, to the peanut butter mixture and combine well to ensure they are fully incorporated into the batter.

Next, I fold the almond flour, coconut flour, baking powder, and salt into the cookie dough, mixing gently with a spatula.

I then stir in 3/4 cup of sugar-free chocolate chips and spread the batter evenly onto the baking pan.

I dot teaspoonfuls of the reserved 1/2 cup of peanut butter evenly on top of the batter and lightly swirl it with a toothpick.

After that, I add dry roasted peanuts, the reserved 1/4 cup of sugar-free chocolate chips, and 1 oz of chopped sugar-free chocolate bar pieces to the top of the bars. I like using a combination of chocolate for these keto chocolate peanut butter bars because it is sure to silence your sweet tooth.

Finally, I sprinkle the bars with sea salt flakes and bake for 35–40 minutes or until they are golden brown.

Once they are done, I allow the cookie bars to cool completely before slicing, and any leftovers can be stored in the refrigerator in an airtight container for up to 5 days or frozen for up to 3 weeks.

Peanut Butter Substitutions

This recipe uses unsweetened, natural, no-stir peanut butter. Regular peanut butter is loaded with sugar, and that’s why it’s so high in carbs, but when you use a natural one that has no added sugar, 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 must ensure 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 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, and 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. That’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.

I don’t advise using Splenda Bake because it’s a 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 to use a granulated sugar substitute to keep things easier, but swapping 1/2 of the sweetener for a brown sugar substitute is doable.
