Mix cinnamon sugar: In a small bowl, combine the granulated sugar and ground cinnamon. Stir well and set aside.
Prep the dough: Open the crescent roll can and unroll the dough onto a clean, flat surface. If using pizza dough, roll it out into a thin rectangle. Brush the entire surface evenly with melted butter.
Add the filling: Sprinkle the cinnamon sugar mixture evenly over the buttered dough, covering it completely.
Roll and slice: Starting from one end, roll the dough tightly into a log. Slice the log into 2-inch segments.
Skewer: Thread each segment onto a skewer, spacing pieces slightly apart so heat circulates evenly.
Cook over fire: Hold skewers over glowing embers or indirect heat (not direct flame), rotating slowly and consistently for 5–7 minutes until the rolls are golden brown and cooked through.
Serve: Carefully remove from skewer. Drizzle with icing while still warm. Enjoy immediately.
