Preheat the Air Fryer to 315 degrees.
In a small bowl, lightly whisk the egg and milk. Put it aside.
Mix the cream cheese and powdered sugar until it's all combined. Then, add the chocolate chips and mix them in. Set this mixture aside.
Separate the crescent dough into 8 triangles. Put two teaspoons of the cream cheese mixture on the wide end of each triangle.
Fold the dough corners over the filling and roll it up, starting from the wide end. Wrap the dough around the cream cheese mixture until you reach the other end. Make sure to seal the edges to keep the filling inside while cooking.
Spray the air fryer basket with non-stick baking spray. Brush on the egg wash and put the crescent rolls in the basket, leaving some space between them so they're not touching.
Cook for 7-8 minutes or until they're fully cooked.
Take the crescents out of the air fryer and enjoy!
