Preheat the Air Fryer to 350°F (175°C).

In a mixing bowl, combine pumpkin puree, brown sugar, and pumpkin pie spice. Stir until smooth and well-blended.

Roll out the thawed puff pastry on a lightly floured surface to 1/8 inch thick.

Spread the pumpkin filling evenly over half of the pastry, leaving a border around the edges. Fold over the plain half to create a pocket and press edges to seal.

Cut the folded pastry into 1-inch strips and twist each strip gently.

Place twisted pastries in the air fryer basket without touching each other.

Cook the twists for about 10 minutes until golden brown.

Remove from the air fryer and allow to cool slightly before serving.
