  • 1 cup smooth peanut butter no added sugar
  • 1 large egg
  • 2/3 cup erythritol
  • 1/2 tsp. baking soda
  • 1/2 tsp. vanilla essence


  • Preheat oven to 350F (180°C) and line a cookie tray with baking paper. Set aside. 
  • Add the erythritol to a Nutribullet or blender and blend until powdered. Set aside. 
  • Add all of the ingredients for the peanut butter cookies into a mixing bowl and mix until a smooth dough forms. 
  • Measure out 2 tbsp. of the dough and roll between your palms to make round balls and place on your cookie tray. Continue until all the dough has been used. 
  • Use a fork to press the cookies down and bake for 12 - 15 minutes depending on your oven. Once they have cooked, remove from the oven and allow to cool for 25 minutes on the cookie tray. Don't touch them yet! 
  • Once they have cooled on the cookie tray, transfer the peanut butter cookies to a cooling rack and allow to cool for a further 15 minutes.
