Start by creaming the sugar, brown sugar, and butter. Mix well, add the egg, vanilla extract, flour, baking soda, salt, and mix well.
Fold in the chocolate chips, mix well, then cover and refrigerate until time to use in the recipe.
Make the brownies, as directed on the box. Spread your prepared brownies into a greased pan, sprayed with cooking spray.
Sprinkle the chocolate chip dough on top of the brownie batter.
Set the pan into the air fryer and set the temperature to 320 degrees F, air fryer setting, for 20 to 30 minutes. Or until the toothpick stuck in the middle comes out clean.
Let cool slightly before slicing.
Plate, serve, and enjoy!
