Make the dough:
In a bowl, combine the peanut butter, sugar, egg, vanilla extract (if you have it), and a little salt. Mix until everything is well blended and forms a thick dough.
Form the cookies.
Take small amounts of the dough (around 1 tablespoon) and shape them into balls.
Press down gently on the balls with a fork to create a pattern on top.
Heat up the Air Fryer before using it.
Heat up your air fryer to 350°F (175°C) for approximately 3 minutes.
Bake the cookies.
Spray a little cooking spray on the air fryer basket or use parchment paper to cover it.
Put the cookies in the basket, making sure to leave some room between them because they will get bigger.
Cook the cookies in the air fryer at 350°F (175°C) for 6-8 minutes, or until the edges turn golden brown. Check on them after 6 minutes to avoid cooking them for too long.
Chill and Serve:
After the cookies are finished baking, allow them to cool in the air fryer for 1-2 minutes before moving them to a cooling rack.
Let the cookies cool down completely (they will become firmer as they cool).
Enjoy your tasty and simple Peanut Butter Cookies made in the Air Fryer!
