Cookie season is upon us my friends and I knew that I needed to share these Keto Peanut Butter Cookies with y'all.
Why?
Well, I just can't get over the fact that this keto version really tastes like the real deal peanut butter cookies! The texture is amazing! They are crisp on the edges and soft and chewy in the middle!!
They satisfy ALL of the cravings with ZERO flour and less than 2 net carbs!
These cookies have been a favorite of mine going back several years, even before I went low carb. I made a version of them with regular sugar because a reader had asked for a gluten-free cookie recipe.
Once I went low carb it was just a matter of swapping out the regular sugar for a good low carb sweetener and BOOM we have a yummy keto AND gluten-free peanut butter cookie that everyone loves!
The keto to this recipe is the peanut butter you use and how long you bake.
You want to use a really smooth and loose/runny sugar-free peanut butter. I use my homemade sugar-free peanut butter.
You also want to make sure that you do not overbake. The cookies are very fragile right out of the oven but will continue to firm up as they cool.

FAQS ABOUT KETO PEANUT BUTTER COOKIES
My cookie dough was really dry and hard to form into a flat cookie. Did you use crunchy peanut butter? Or maybe thick store-bought peanut butter? The only time I have issues with the texture is if I use thicker peanut butter.
Can I add chocolate chips to these Keto Peanut Butter Cookies? Absolutely! Add choc chips, chopped nuts, dried fruit, or whatever your little heart craves!
How should I store these Keto Peanut Butter Cookies? Store peanut butter cookies in a sealed container at room temperature. They will keep fresh for up to 2 weeks. Alternatively, you can store them in the fridge for up to a month. You can also freeze the cookies for up to 6 months.
