Preheat the oven to 400°F and line two baking sheets with parchment paper. Set them aside.
Unfold the puff pastry sheet onto a lightly floured countertop surface and then brush the melted butter onto its surface using a pastry brush.
Take a small bowl and mix the brown sugar and ground cinnamon in it. Then sprinkle it over the pastry and pat it down to adhere with the butter.
Now slice the pastry sheet into 12 thin strips from top to bottom and then twist each one 6 to 7 times with the cinnamon layer facing inward.
Place six twists on each baking sheet about 2 inches apart and bake for about 15 minutes until lightly browned then serve hot or let cool to room temperature.
