Sweet Orange Rolls

For the filling: After the dough comes together and has risen, on a well-floured surface, roll the dough out to a 15 by 11-inch rectangle. In a mixing bowl add sugar, 2 tablespoons orange juice, and 1/2 the orange zest. Spread the softened unsalted butter over the dough leaving a 1/2-inch border. Sprinkle orange sugar evenly over the dough. Starting with the long side, roll up dough tightly ending with the seam side down. Cut 18 slices each about 1/2-inch thick. Place in 2 (9 by 13-inch) greased baking dishes and cover with a kitchen towel. Allow the rolls to rise in a warm environment for an additional 15 to 20 minutes or until doubled in size. Bake at 375 degrees F until the tops are golden brown, about 15 to 20 minutes. Remove from oven and brush tops with melted butter and cool on a cooling rack. For the glaze: In a mixing bowl, combine the powdered sugar, 2 tablespoons orange juice, remaining zest, and softened butter. Spread the glaze over the warm rolls.
