Ingredients

  • 1 cup creamy peanut butter
  • ¾ cup granulated sugar
  • 1 large egg

Instructions

  • Mix peanut butter, sugar, and egg together in a large bowl until smooth and creamy.
  • Roll the peanut butter mixture into small balls, about a tablespoon in size. Line the air fryer basket with a parchment or silicone liner and place a batch of the balls on the liner, spacing them about an inch apart. Flatten each one with the tines of a fork, making a crisscross pattern.
  • Cook at 300°F until cookies are golden brown, 7-8 minutes. Remove the basket from the air fryer and allow cookies to set for 2-3 minutes in the basket. Then, using a spatula, transfer cookies to a wire rack to cool. Repeat with the remaining cookie dough.

Notes

  • You don’t need to make the crosshatch pattern fork marks- that’s just for decoration. But you do need to flatten these cookies before baking since they won’t spread much. You can use a fork or the bottom of a glass.
  • Use a silicone liner or perforated parchment liner for easier clean up. You also use a piece of parchment paper and punch your own holes in it.  Do not put the parchment paper in the air fryer by itself- make sure it's weighed down by the cookies.  Otherwise it can fly up into the heating element and catch fire. Read my post on Can you use parchment paper in an air fryer?  
  • The cookie will be very soft so leave them in the air fryer basket for several minutes afterwards to let them set before trying to remove them.
