In a large mixing bowl, mix together the flour, baking powder, butter, powdered sugar, egg yolk, brandy, and vanilla extract.
Mix well, being sure to scrape the sides down.
I use an ice cream scooper, to get my round cookies,
Spray your air fryer tray (see my blog post on how to bake cookies in a basket) with olive oil spray and then scoop the batter onto the pan (about 1 tablespoon)
Use a spoon to flatten the cookies.
Set the tray into the air fryer and set the temperature to 320 degrees F for 5 minutes.
Let cool, as they come out of the air fryer oven. I did two batches. Then coat them with powdered sugar.
Plate, serve and enjoy!
