Mix Cinnamon Sugar: In a small bowl, combine the sugar and cinnamon.
Prep Dough: Unroll the dough into a flat rectangle. Brush lightly with melted butter.
Add Filling: Sprinkle the cinnamon sugar evenly over the buttered dough.
Roll & Slice: Cut the dough into strips, roll each strip tightly, and slice into small rolls if needed.
Skewer: Thread each roll onto a skewer, spacing them slightly apart.
Cook Over Fire: Roast over glowing embers (not direct flame), rotating frequently, for 5–7 minutes until golden brown.
Serve: Carefully remove from skewer, drizzle with icing if desired, and enjoy warm!
