Preheat oven to 350 degrees and line a sheet pan with parchment.
Lay out the thawed, but still cold, puff pastry on a lightly floured surface.
Cut the pastry dough in half and place one half to the side.
Using a rolling pin, roll out the dough so its a little thinner, longer and wider.
Brush the top with melted butter.
In a small bowl, combine the sugars and cinnamon.
Sprinkle a couple tablespoons of the mixture on top of the butter.
Roll up the pastry dough, starting from the long edge.
Using a sharp knife, cut the roll in half longways, straight down the middle.
Twist one side at a time and coil into a tight circle.
Place on the parchment lined sheet pan.
Repeat steps with remaining pastry dough.
When all the twists are placed on the sheet pan, brush the tops with the remaining butter.
Bake for 20 - 22 minutes.
Remove from oven.
In a small bowl, mix the powdered sugar and milk.
Drizzle on top of the Cinnamon Twists.
Serve and enjoy!
