In a medium bowl, combine granulated sugar, ground cinnamon, and a pinch of salt. Mix well and set aside.

Lightly dust a clean surface with flour and unfold the puff pastry into an even rectangle.

Melt the unsalted butter and brush it over the puff pastry, then sprinkle the cinnamon-sugar mixture on top.

Slice the pastry into 1-inch wide strips and twist each strip tightly to create a spiral shape.

Preheat your air fryer to 350°F (175°C) and cook the twists for 8-10 minutes until golden brown.

Remove the twists and transfer them to a wire rack to cool.

Mix powdered sugar with milk or water for an optional glaze and drizzle over the cooled twists.

Serve warm or at room temperature and enjoy!
