Gather your ingredients. In a medium-sized bowl, add melted butter and sugar. Whisk together while slowly adding the vanilla and egg. When fully combined, add the flour, baking soda, and a pinch of salt. Stir until the batter makes a soft dough.

Use a small piece of parchment paper to line the inside of the basket in your air fryer, leaving a bit of room around the edges to allow some airflow. Scoop your dough with a spoon and place it into the basket around two inches apart, leaving room for expansion. Flatten slightly with a light press of the finger.

Bake for 7-8 minutes at 350 degrees in the air fryer. Cookies will have golden edges and a soft, chewy center. Let cool for about five minutes before serving and then enjoy!
