In a medium mixing bowl, combine the 4 ounces of softened cream cheese, ½ teaspoon vanilla, 3 Tablespoons powdered sugar, and 1 Tablespoon fresh lemon zest using a hand mixer. When the mixture is smooth, set this aside.
Open the can of crescent rolls and separate the 8 triangles along the seams. Place one triangle of dough on a flat surface, with the wide end closest to you.
Spread 1 Tablespoon of the prepared cheesecake mixture onto the triangle, beginning at the wide end nearest you and going about ⅔ of the way to the tip of the triangle.
Place about 10-12 blueberries (depending on the size of the blueberries) across the wide end of the triangle (nearest you), leaving about a half inch empty at the edge.
Now roll the crescent up, wide end rolling toward the point. Press the tip of the triangle firmly into the crescent.
Spray the air fryer basket with oil spray.
Place the finished crescent directly into the air fryer (no parchment paper needed).
Repeat this process with all of the crescent rolls. If you can’t fit them all in the air fryer without crowding, you could bake them in batches.
Air fry the rolls for 8-10 minutes at 375 degrees. (If your air fryer bakes quickly you will want to check them at 6 minutes.)
