Although I’ve seen plenty of low-carb keto peanut butter cookie recipes that use only three basic ingredients, you know the flourless peanut butter cookies, I must tell you I’m not a fan.

Yes, those are easy cookies but the flavor and texture just didn’t measure up for me.

Remember, I was after a true peanut butter cookie experience.

Please understand that when this girl gets a craving it’s vital I come up with a recipe alternative that works because cheating is just not an option.

Not unless I’m willing to pay for the days of inflammation I’m bound to experience afterward. Trust me when I tell you that the battle to be pain-free is challenging enough when I eat according to plan.

So I don’t need to make matters worse by intentionally eating off course. I say all that to say that, a substitute needs to be spot on to avoid a setback for this girl.

The problem I had with these cookies is that they just did not have enough structure and crumbled too easily. And that’s not what I was craving.

I wanted a keto peanut butter cookie that I could sink my teeth into and that would remind me of the one I made countless times for my family.

Best Sugar-Free Sweeteners For Sugar-Free Peanut Butter Cookies

When it comes to choosing a low-carb sweetener for these keto cookies, any of your favorite equivalents would work. Just keep in mind that they have varying degrees of sweetness.

Some sugar substitutes measure cup for cup, while others are not as sweet as sugar and would require more in order to get the same level of sweetness.

If you are regular on our site, you know by now that I’m a huge fan of Lakanto Monk Fruit Sweetener.

This is because the texture of Lakanto is spot on since there is barely any aftertaste.

It is a monk fruit and erythritol blend. If you have not given this all-natural sweetener a try, you have no idea what you are missing. 

That being said, I’m also partial to Swerve another erythritol blend.  It works well in this recipe and is a great choice if you are looking for a sugar substitute that has no bitter aftertaste and measures just like sugar.

Swerve is made from ingredients found in select fruits and starchy root vegetables and contains no artificial ingredients, preservatives, or flavors.

Like Lankanto, Swerve has a 0 % impact on blood sugar. I know some of you are stevia fans; if that’s you, you can use the stevia and erythritol-based brand Pyure in this recipe.

However, it’s important to note that if you are using Pyure you will want to use 1/2 the amount called for in this recipe since it’s a much sweeter option.

Lastly, if you cannot easily find a more natural sugar substitute, you can also use Splenda with great success. You will want to use the Splenda that has a bulking agent. It’s the one that comes in larger bags.

How To Make Perfect Keto Peanut Butter Cookies

With very little prep time you can enjoy low carb cookies that have a very low carb count and tastes like the real thing.

You’ll begin by preheating the oven to 350 degrees. And preparing the cookie sheet by lightly greasing or lining the baking tray with parchment paper.

Then, using an electric mixer, you’ll combine peanut butter, with the butter, sugar substitute, vanilla extract, and egg.

Next, to the wet ingredients, you’ll add the dry ingredients, the almond flour and baking powder, and salt.

Beat the mixture until fully incorporated.

Once the cookie dough is ready, drop by the tablespoon or small cookie scoop of dough to form little balls and place them on the prepared cookie sheet.

Then flatten each cookie with the tines of a fork to make a crisscross design.

Next, bake them in the 350-degree oven until lightly brown around the edges around for about 10-12 minutes.

Last but not least, allow the cookies to cool completely before eating and storing as these cookies can be very fragile until they are fully cool.

Keto Baking

Can I tell you that when I first started baking with low-carb ingredients, I really struggled? That’s because keto baking can be a bit overwhelming.

There are just so many ingredients that simply do not behave exactly like their high-carb counterparts. Frankly, it was frustrating.

Especially since I was an experienced baker, who was used to baking with her eyes closed. It was enough to make me want to throw in the towel.

Today, I understand keto baking, but that was not always the case.  

Trust me those first attempts were an epic fail.   So stay the course because the satisfaction of knowing you are not only making something delicious but healthy is quite rewarding.

How much granular sugar sub should i reduce, my family said it had a bit of a cooling effect bc of the swerve

Hilda Solares

Friday 12th of May 2023

Hi Danny, You can try reducing to a total of 3/4 cup and as little as 1/2 cup to see if this helps or try using granulated Monkfruit I prefer Lakanto

Wow what a great cookie dough they're in the oven as I'm typing. I used caramel essence and oh my word the taste is incredible. Whether or not the cookies turn out good I'm happy with the dough😁😁

Thank-you. I don’t prefer the 3-ingredient peanut butter cookie recipes, either. This one is yummy.

Awesomeness Pamala! So happy to hear you are enjoying the recipe too.

The flavor of these peanut butter cookies is spot on. My husband loves peanut butter cookies so I made these for him. My only issue is probably one that can’t really be solved because, being on keto, everything is weird. The texture of these cookies, although not bad, we’re more like little cakes. Reminded me of the peanut butter mug cake I usually make. Too dense to be a cake but too spongey to be a cookie. My problem may be that I did not use actual peanut butter. I used PB Fit to which I added enough water to make a very thick peanut butter. Either way, these were really good cookies but I would like something with more crunch/texture. Maybe I’ll add some toasted crushed peanuts, next time or try actual peanut butter.

Hi Liz, I definitely believe the use of PB Fit instead of real peanut butter is the reason for that texture. I recommend you give the recipe a try as written for the best results.

I made the cookies with almond butter and used raw honey as sweetner.. I used 3/4 c of honey rather than the whole measurement. I also wish to say I live over 5,000 feet up.. the cookies were great! They cooked much quicker than the recipe called for.. by 3 minutes perhaps.. and they did need more almond flour as the batter was pretty damp when mixed with what was suggested. I suspect the honey had something to do with that. Meanwhile.. Great cookies! Thank you!

Hi Candy, The honey most definitely did add more moisture to the recipe but I am happy to hear you were able to adapt the recipe to your preference.
