Preheat your oven to 400°F (200°C) and prepare a baking sheet lined with parchment paper.
Open the package of refrigerated pizza dough and roll it out on a lightly floured surface into a rectangle about 1/4-inch thick.
In a small bowl, combine the granulated sugar and ground cinnamon.
Pour the melted butter over the rolled-out dough, brushing it to cover the entire surface evenly.
Generously sprinkle the cinnamon sugar mixture over the butter-coated dough.
Cut the dough into strips about 1-inch wide, twist each strip a few times, and form it into a knot shape.
Place the knots in the preheated oven and bake for about 15-20 minutes or until golden brown.
