Step 1

In a large mixing bowl, combine the butter, brown sugar, and granulated sugar. Using an electric hand mixer, beat on medium-high speed for about 3 minutes, stopping to scrape down the sides and bottom of the bowl halfway through, until well combined.

Step 2

Add the egg and vanilla extract and beat on medium speed until well combined, about 1 minute. Scrape down the sides of the bowl again.

Step 3

Add the flour, then sprinkle the baking soda and salt evenly over top. Mix on low speed until no dry bits of flour remain, 1 to 2 minutes. Stir in the chocolate chips by hand with a spatula.

Step 4

Divide the dough into 12 equal pieces (about 2½ tablespoons each) and roll into balls.

Step 5

Preheat the air fryer to 300°F if your model requires it.

Step 6

Line the basket of an air fryer with parchment paper (cut to fit the basket if you don’t have an air fryer liner). Working in batches, place 4 pieces of dough in the basket, equally spaced.

Step 7

Air fry for 14 minutes at 300°F. Remove the basket from the air fryer and let the cookies cool for 4 minutes on the parchment paper, before transferring to a cooling rack to cool completely. Continue cooking the rest of the dough balls.
