Preheat the air fryer to 340°F (170°C) and prepare a 6-inch round baking pan with nonstick spray.

In a mixing bowl, cream together softened butter, granulated sugar, and brown sugar until smooth and fluffy, about 2-3 minutes.

Add egg and vanilla extract to the creamed mixture and mix until fully combined.

Gradually incorporate flour, baking soda, and salt into the mixture until a soft dough forms.

Fold in your choice of baking chips until evenly distributed throughout the dough.

Transfer the dough into the prepared baking pan, pressing it down evenly to cover the bottom.

Place the pan in the preheated air fryer and cook at 340°F for 13 minutes until the top is golden brown.

Reduce the temperature to 310°F (155°C) and continue cooking for another 6 minutes until set.

Allow the pizookie to cool slightly before serving.
