Melt butter in the microwave and let it cool to room temperature. Line a pan with 2 sheets of foil to fit your air fryer insert, folding edges up 2 to 3 inches high. Generously grease with cooking spray and set aside.
In a medium bowl, whisk melted butter, granulated sugar, and brown sugar until fully combined, about 1–2 minutes. Add egg and vanilla and mix until combined. Heat the empty air fryer to 350°F for 10 minutes.
Mix flour, baking soda, and salt into the wet ingredients. Stir in chocolate chips.
Spread smooth dough firmly and evenly in the prepared foil “pan.” Remove the hot air fryer insert and press foil pizookie into the bottom of it. Bake at 350°F for 8–10 minutes (see note 1).
Remove the foil pan with tongs and transfer to a plate. Top with ice cream and serve immediately while gooey and slightly under-baked in the center. Best enjoyed fresh!

Notes
Note 1: Air fryers vary a bit from brand to brand. Occasionally check to make sure the cookie isn’t burning. Keep in mind, air fryers cook a lot faster than oven, so it can go from perfect to burnt in as little as a minute.
