Puff pastry cinnamon twists are a fun dessert that pairs well with coffee or tea. They're sweet, buttery, and cinnamon-y, and come together quickly with the use of frozen puff pastry dough.
Preheat oven to 400 degrees Fahrenheit. Line two baking sheets with parchment paper and set aside.
Unfold puff pastry sheet onto a lightly floured surface. Roll gently with a rolling pin to remove creases. Using a pastry brush, brush melted butter over the entire surface of the puff pastry.
In a small bowl, combine the brown sugar and ground cinnamon. Sprinkle cinnamon sugar evenly over dough and pat gently to adhere with butter.
With a sharp knife (or pizza cutter), slice pastry sheet from top to bottom into 12 thin strips. Twist each strip about five or six times around, with the cinnamon layer facing inward (if you're having trouble, try starting the twist around your finger to get the plain side facing out).
Place twists 2 inches apart on two parchment lined baking sheets (they will spread and untwist slightly when baking). Bake for 14-16 minutes, or until lightly browned.
Serve cinnamon twists warm or at room temperature.

Notes
One sheet of puff pastry should be sliced into 12 thin strips (or more). Thicker strips, or shorter strips (like cutting a twist in half) will unravel completely when baked in the oven.
Puff pastry is best enjoyed the same day, but will keep for up to two days in a tightly sealed container at room temperature.
