Mix cinnamon and sugar together in a small bowl and set aside.

Thaw puff pastry sheets, then cut into four even squares for each pastry sheet (8 total squares). Brush with melted butter.

Evenly distribute the cinnamon/sugar mixture over the pastry sheets. Using a pizza cutter, cut the squares into 1" strips. Lay one strip down on top of another with sugar sides facing each other, gently press together and then twist.

Lay the twists down on a baking sheet and bake par the pastry sheet instructions. Remove from oven, let cool and serve.
