Melt the butter in a medium bowl and set it aside.
In a separate large bowl, combine the flour, oats, cinnamon, baking soda, and salt. Whisk it together and set it aside.
Next, take the butter bowl and add the apple pie spice, vanilla extract, and brown sugar. Mix it well. Add in the applesauce and the egg.
Finally, combine the two bowls. Add the apple mixture to the dry ingredient bowl.
Mixing everything thoroughly.
Fold in the chopped apple pieces.
Preheat air fryer to 315 degrees F, air fryer setting.
Then, line the air fryer basket with parchment paper.
Using a small ice cream scoop or a spoon, scoop the cookies out one by one making each cookie ball about two inches wide.
Place each cookie dough ball onto the parchment paper, leaving about an inch and a half of space between them. It’s important to leave that space because they do spread out.
You will probably have to do multiple batches. I was able to fit in six cookies at a time.
In between batches, place the bowl of uncooked cookie dough in the fridge so that it stays chilled.
Air Fry cookies for about 6-8 minutes.
Repeat until all cookies are made.
Remove cookies from basket and place on cookie rack to cool.
To make the glaze: combine confectioners sugar and heavy whipping cream in a bowl, mix well. If you’d like it thinner, add more heavy whipping cream. If you’d like it thicker, add more sugar once cookies are completely cool, drizzle glaze over them.
