Instructions
Scroll to the recipe card at the bottom for the FULL recipe details.
Step 1
First, add the sweetener, peanut butter, and egg to the bowl and mix them up using a spoon or spatula. Blend until it forms a dough.
Step 2
Second, using the cookie scoop, roll the dough into heaping tablespoon-sized balls and place them on the baking mat on the prepared baking sheet.
These cookies will spread out on the cookie sheet, a bit so leave some room between the balls of dough.
Step 3
Next up is the classic fork criss-cross pattern on the top.
Lightly press the fork down to flatten the ball, then slide the fork off.
Step 4
Then, press the fork down in the opposite direction to create the criss-cross style on the top of the cookie dough.
Step 5
Finally, they are ready to bake.
Pop them into the preheated oven.
Step 6
Bake until puffed and golden.
Next, transfer them to a cooling rack and let them cool to room temperature.
Expert Tip!
Letting the cookies cool on a rack allows them to firm up, making them easier to handle and less likely to break.
Substitutions
- After putting it to the test, we found that any nut butter works well in this recipe. Substitute almond butter, pecan butter, or cashew butter to add variety.
- Use sunflower seed butter instead of nut butter if you have nut allergies.
- Replace the monkfruit for Swerve sugar substitute.
Recipe Variations
- Shake a bit of sea salt on the tops when they come out of the oven for a salty punch.
- Add a splash of vanilla extract to add that classic warm flavor.
- Sprinkle in a few sugar-free chocolate chips.
- For a festive vibe, add a bit of ground cinnamon and ginger to the cookie dough before baking.

This is the easiest cookie recipe I have ever made. I used “natural” creamy peanut butter and monkfruit sweetener. The first batch was too sweet for my taste. I used about half of what it calls for and they were delicious!!!!
Amazing! Thanks so much for the great feedback. I love that you modified it for your sweet spot.
I did not like these cookies at all. The monk fruit was too sweet. Threw out the entire batch.
Is the nutrition information for 1 cookie? Thx! Can’t wait to try these!
Yes, it is broken down per cookie. Hope you enjoy them. 🙂
Great cookie recipe, love it how you use monk fruit as a sweetner, a perfect keto recipe
I will pass this on to my sister as she is on the Keto diet, she will love this recipe 🙂
Thanks for sharing!!
I made these this weekend and they turned out great. I recommend them. Even my non-keto family loved them.
That’s awesome Debi! Love when the fam approves. 🙂 Thanks!!
Wow, I can’t not make these again – they are such a simple yummy recipe. Thanks for sharing!
Wow! This recipe looks so simple. Just pinned to make it soon.
There is something about a simple peanut butter cookies that is so addictive. These sound and look fantastic. I know they would be a hit in our house. I would have to make a double batch to make sure I got some.
Be careful. Erythritol is the main ingredient in this Monk fruit.
This first recipe ingredients state its “pure monk fruit product without erythritol”, so why are you saying it isn’t now? Very confusing, since I’m looking for pure monk fruit recipes.
Sorry for the confusion Ruth! I had to update the recipe with an erythritol blend because the pure monk fruit is way too sweet for this recipe.
