If you’re like me and have a weakness for cookies, you’ll love these low-carb peanut butter cookies! They’re perfectly chewy and delicious, and you can eat more than one without overloading on sugar.
In fact, these cookies are completely sugar-free and only have 4 grams of carbs (mostly fiber) per cookie! This makes them suitable for even a ketogenic diet.
The batter comes together in just 1 bowl using 5 simple ingredients. No fancy kitchen equipment needed, just mix it all up and bake!
I recommend making these cookies at the start of the week so you have a treat ready to enjoy or share with friends and family. They will be amazed at how easy and tasty low-carb baking can be
How to make low-carb peanut butter cookies
It only takes about 5 minutes to mix up the batter, and then you’ll have a delicious treat ready to be enjoyed throughout the week!
You can see how I make them in this short video or read the step-by-step instructions below.
Step 1: Preheat oven to 350F (180°C) and line a cookie tray with baking paper. Set aside.
Step 2: Add the erythritol to a Nutribullet or blender and blend until powdered. Set aside. If using a confectioner’s low-carb sweetener, you can skip this step.
Step 3: Add all of the ingredients into a medium mixing bowl and mix until a smooth, glossy dough forms.
Step 4: Roll about 2 tbsp of dough between your palms to form a ball, then place on the prepared cookie tray. Repeat until all dough has been used. You should end up with 12-14 cookies.
Step 5: Use a fork to flatten the cookies, creating a criss-cross pattern across the top.
Step 6: Bake the cookies for 12-15 minutes.
Step 7: Remove from the oven and allow to cool for 25 minutes on the baking tray, then transfer to a cooling rack for another 15 minutes.
Now your peanut butter cookies are ready to enjoy!
Give your cookies time to cool
Even though your cookies are going to smell amazing when you take them out of the oven, resist the urge to sample one right away! Make sure you give them the full amount of time to cool on the baking tray and the cooling rack.
Because this recipe does not contain any flour, the cooling step is crucial to allow the cookies to firm up. The longer they are able to cool, the better the texture will be. You don’t want them to fall apart when you go to eat them!
Be patient with these. I promise, it’s worth it 🙂
Customizing the recipe
There are a few different variations for this recipe that you can try. Don’t be afraid to get creative!
We all know that peanut butter and chocolate are a classic combination. For a little extra sweetness, add in some sugar-free chocolate chips. Or, for a truly decadent treat, half-dip each cookie in melted sugar-free dark chocolate. This takes the cookies to a WHOLE new level! Just be sure you allow the cookies to fully cool before dipping.
To give the cookies a nutty texture, try using crunchy peanut butter instead of creamy.
You can also swap out the peanut butter altogether and use a different nut butter. Cashew or almond would work well in this recipe!
Keep in mind that the peanut butter will add the most taste to the cookies, but if you prefer not to use it or have an allergy, any nut butter will do.
Storage
I recommend storing your cookies in an airtight container in the refrigerator for up to a week. They will stay fresh, soft, and delicious!
For longer storage, you can freeze them instead and enjoy for several months.

Recipe Notes
Nutrition Info Per Serving
Thank you so much for this recipe! My dad is diabetic and its not easy to find a recipe he likes. I used Monk Fruit Sweetener in place of Erythritol. They were delicious. Will be making these again for sure 😊
Made these used strained unsweetened applesauce sause . Tasted good . Thank you ☺️
How much did you use? Did you change the other ingredients at all?
Just made a batch. Super easy. Used Splenda 1:1. Worked fine. They came out perfectly golden w/o any burnt edges. I am at 7,000 ft and typically have a problem with cookies being too flat or not baking correctly. These were beautiful and are a holiday present to sweeten up a testy, diabetic gentleman. (Made a tiny 13th test cookie so I know they are delicious!)
Excellent, I’m so glad to hear that they came out well for you too
Was expecting less, but got more! I still remember what the high carb/sugar peanut butter cookies taste like, and these are the closest thing I have tasted to what I remember. I followed the directions and the texture was good and my sone even ate 3 of them and said they were pretty good. Definitely will make again and again.
Thank you
I made this recipe for friends on a keto diet. they LOVED it. Be sure to follow the instructions to let them cool.
Can these be made with monkfruit sweetener?
That should work just fine but you’ll have to look up how much to use, I’m not sure it will be 1:1
The bag of monkfruit sweetener says it’s a 1:1 substitute. Thank you so much. My boyfriend was just diagnosed after being hospitalized, and I want some sweets that will make this diet change easier for him.
Hey there, I would like to make these for my sister who has gestational diabetes, the local stores only have truvia, which says on the bag its 1 to 1/2 ratio (1 cup sugar to 1/2 cup truvia)…do you think truvia would work for these cookies?
I haven’t tried Truvia for this recipe but think it could work. I hope you both like them
Is this nutritional information per cookie?
Yes, assuming you make 12 cookies
These came out great! I also added some no sugar added chocolate chips to them. Thanks!
Went together fine and they taste great. Thank You!
