If you’re on the hunt for Keto-friendly sugar-free peanut butter cookies or flourless peanut butter cookies, this is the low carb peanut butter cookies recipe for you. 

Crunchy vs. Soft Peanut Butter Cookies:

We get it. Most peeps are either ‘Team Crunchy’ or ‘Team Soft’. This sugar free peanut butter recipe can be either. If you prefer a softer texture, eat them as soon as they start to cool down as they crisp/firm up as they cool. If you like crispy peanut butter cookies, plan on letting them cool down for a minimum of 30 minutes to an hour. 


Keto Peanut Butter Cookies:

  1. Mix in some crushed whole peanuts for a little crunch. Just add them with the other ingredients. No adjustment to the cook time would be needed. It will affect the nutritional value, however. 
  2. If you’re into “salty” add 1/4 tsp of sea salt to the mix. Go big or go home, right?

  • Pre-heat the oven to 350F and line a baking sheet with parchment paper. Set aside.
  • Add all (4) ingredients to a large mixing bowl and stir until fully combined.
  • Drop heaping tablespoonfuls (approx. 1 Tbsp each) of dough onto the prepared baking sheet.
  • Place on the prepared baking sheet and flatten with a fork to make a criss cross pattern (optional- but pretty).
  • Bake for 12 minutes and let cool before eating.


  1. Our favorite sugar-free peanut butter is the Kirkland brand from Costco. 
  2. We don't care for overly sweet goodies - if you do, you can increase the Erythritol to 1/3 or 1/2 cup. 
  3. Store in a Ziploc bag or air-tight container for up to a week.
  4. How did we get to 1 net carb? We subtracted the fiber and sugar alcohols from the total carbs since Erythritol isn't absorbed by the body.
