In a large bowl, add Butter, Granulated Sugar, Brown Sugar, 1 Tsp of Sea Salt, and Vanilla Extract.
Using a hand mixer beat together for a few minutes.
Add Flour, Baking Soda, and Egg.
Mix until everything is completely blended and there are no lumps.
Next, use a spatula to fold in the chocolate chunks and Pretzels.
Use a cookie scoop (about 2 tablespoons each) to form balls about 1.5 inch in diameter. Set them on a baking sheet lined with parchment paper.
Freeze for 15 minutes and then store in an air-tight freezer bag in the freezer until ready to bake.
If baking immediately…
Preheat Air Fryer to 350 degrees
When preheated, add a piece of parchment paper to the Air Fryer rack that is small enough to let air come in around all the sides. Add the cookie balls on top.
Depending on the size of your Air Fryer you can probably get between 5-9 cookies, at a time.
Place in air-fryer and bake for 8 minutes.
Let sit in the air-fryer for 3 minutes
Allow to cool on rack.
Sprinkle with a pinch of Sea Salt and enjoy!
