Partially thaw your puff pastry, it will make it easier to cut.
In a small bowl mix together the egg and vanilla extract.
Then spread it over the thawed puff pastry.
Sprinkle with cinnamon.
Then cut it into squares, place in an oiled air fryer baking sheet or in a greased basket.
Place in the oven. Set temperature to 300 degrees F, for 4 minutes, after 4 minutes flip and air fry for another 3 minutes.
This is when I took them out of the air fryer.
I dusted them with confectionary sugars and some fruit.
