These quick and easy peanut butter cookies are made with just three ingredients and cooked in the air fryer. They have a soft center with a slightly crispy edge and are perfect for a quick dessert or snack.
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 ball with the tines of a fork, making a crisscross pattern.
Cook at 300°F for 7-8 minutes, or until cookies are golden brown.
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
For a little extra sweetness, press a chocolate kiss into the center of each cookie as soon as they come out of the air fryer.
