Preheat oven to 425ºF and line a baking sheet with parchment paper. Open the pizza dough and roll it out flat. Brush the top of the dough with the softened butter. Stir together the cinnamon and sugar then sprinkle evenly over the butter. Carefully roll up from the short side into a log and cut into 16 slices. Place slices on a baking sheet and bake for about 8 minutes. Remove from oven and cool. Whisk together glaze ingredients and drizzle over buns.
If you place the buns closer together on the baking sheet, they will be doughier. However, if you spread them out more, they will be crunchier. You can also add nuts or raisins if desired.
