Preheat oven to 400°F (200°C).

Roll out thawed puff pastry sheets on a lightly floured surface.

Cut each sheet into 4 equal squares.

In a small bowl, mix granulated sugar, ground cinnamon, and a pinch of salt.

Brush pastry squares with melted butter, then sprinkle with cinnamon-sugar mixture.

Twist each square into a spiral shape.

Place twists on a parchment-lined baking sheet, leaving space between them.

Bake for 12–15 minutes, until golden brown and puffed.

While baking, whisk powdered sugar, milk, and vanilla extract until smooth to make icing.

Let twists cool slightly, then drizzle with icing before serving.
