On a clean work surface, sprinkle some flour and lay the first puff pastry sheet down. Using a pastry brush spread half of the melted butter on the pastry sheet
Make the cinnamon mixture. Then sprinkle half of the cinnamon sugar mixture and press the cinnamon sugar mixture into the pastries, so it sticks to the butter
In a small bowl mix together the powdered sugar, vanilla extract, and heavy cream. You can add a splash more of cream if you want a thinner glaze. Drizzle on top of the puff pastry cinnamon rolls.
