  • cookie tray


  • 1 cup peanut butter*
  • 1 large egg
  • 3/4 cup sugar*


  • Preheat the oven to 350F degrees and line cookie sheets with parchment paper or baking mats.
  • In a medium bowl stir together the peanut butter, egg and sugar until smooth. This can be done by hand or with an electric mixxer.
  • For the dough into balls about 1 tablespoon in size.
  • Place 2 inches apart on the lined cookie sheets and lightly press the top of each cookie down with a fork.
  • Bake for 8-10 minutes or until the tops look set. 


  1. I do not recommend using natural or homemade peanut butter. Smooth, American-style peanut butter such as Skippy, Jiff or Kraft work perfectly. Crunchy peanut butter is ok. 
  2. Feel free to use 1 cup sugar for sweeter cookies. White sugar can be substituted with brown sugar for a more caramel flavor or palm sugar. Do not substitute sugar with honey, agave or maple syrup.
  3. If the cookies spread too thin, pop the dough in the fridge for 30 minutes first. In some countries, the consistency of peanut butter can be a little different and can cause the cookies to be too thin or too thick. Unfortunately, I cannot test the recipe with every variety and brand of peanut butter.
  4. Store cookies in an airtight container at room temperature for up to 4 days.
  5. Nutrition information is an estimate only. It is based on 1 cookie, assuming the recipe yields 18 equal-sized cookies.
