Make the dough: Cream together the butter, brown sugar, and granulated sugar until fluffy. Add the egg and vanilla and mix well.
½ cup unsalted butter, softened, ½ cup brown sugar, ¼ cup granulated sugar, 1 teaspoon vanilla extract, 1 large egg
Mix dry ingredients: Whisk together the flour, baking soda, and salt in another bowl.
1 ½ cups all-purpose flour, ½ teaspoon baking soda, ½ teaspoon salt
Combine: Add the dry ingredients to the wet ingredients and mix until just combined. Fold in the mini chocolate chips.
¾ cup mini chocolate chips
Chill the dough: Refrigerate the dough for 30 minutes to help prevent spreading.
Shape the dough: Roll or press the dough into a rectangle about ¼ inch thick on parchment paper. Try to keep the thickness as even as possible so the cookie fries cook evenly and brown at the same rate.
Cut the cookie fries: Slice into thin sticks about ½ inch wide and 3–4 inches long. If the dough becomes soft or sticky while cutting, chill it again for 10 minutes before continuing. Cold dough gives cleaner cuts and helps the fries hold their shape better.
Preheat the air fryer: Preheat to 350°F for about 3 minutes.
Cook: Place cookie sticks into a parchment-lined air fryer basket with space between them. Cook for 7–9 minutes until the edges look golden brown and lightly crisp while the centers still look slightly soft. Slight spreading is completely normal.
Cool slightly: Let the cookie fries cool for about 5 minutes before serving. They’ll continue firming up slightly as they cool while staying soft in the center.
Serve: Enjoy warm with dipping sauces if desired.
