Defrost the frozen puff pastry according to the package instructions.
Preheat your oven to 400F (200C) and line a baking sheet with parchment paper.
In a small bowl, combine the melted vegan butter with 2 tablespoons of sugar and 1/2 teaspoon of ground cinnamon. Mix well.
On a lightly floured surface, roll out the defrosted puff pastry into a rectangle about 1/8-inch thick.
Slice the rolled pastry into strips about 1 inch wide, twist each strip into a knot, and place it on the prepared baking sheet.
Brush each knot with the butter-sugar mixture and sprinkle with remaining sugar and cinnamon blend. Bake for about 25 minutes or until golden brown and flaky.
