3 Ingredient Keto Peanut Butter Cookies


  • 1 large egg
  • 1 cup peanut butter   Smuckers Natural peanut butter has nothing but nuts and salt
  • 1/2 cup keto approved sweetener of your choice Xylitol, erythritol, Pyure or monk fruit each of these sweeteners may be a different ratio compared to regular sugar.  Please take that into account when you measure out a half a cup


  • Preheat the oven to 350 degrees.
  • In a medium size bowl, add all the ingredients in a bowl and mix them all together until it’s well combined.
  • Roll the dough into 1 inch balls using a scoop or your hands.
  • Place the balls of dough on a cookie sheet lined with parchment paper or a silicone baking mat.
  • Tip:  Those silicone baking mats are amazing!  Cookies are evenly cooked and the cookie crust comes out perfect every single time!  If you don’t have any, I highly recommend ordering this Silicone Baking Mat Set on Amazon.  It’s money well spent!
  • Press down on each ball with a fork twice in opposite directions creating a criss-cross pattern on each cookie as seen in the photos below.
  • You will bake these cookies for about 12 to 15 minutes or until golden brown.
  • Allow them to cool down for about 5 minutes before removing them from the tray.
  • Store them in an airtight container if you have any left after the family gets a sniff of the wonderful aroma that leads through the house and gets them hovering over you in the kitchen just waiting to devour them!
