For the dough:
In a stand mixer, add all the dough ingredients and mix until a smooth dough is formed.
Place in a greased bowl, cover and let rise until doubled in size about a 1 ½ hours.
Filling:
Mix sugar and cinnamon until well combined.
Making the rolls:
After dough has risen, turn it out onto work surface and roll into an 11x20 inch rectangle.
Spread the butter over the dough leaving a 1 inch border on the long end closest to you and sprinkle with cinnamon sugar.
Starting with long end farthest from you, roll the dough toward you and the uncovered border.
Use a serrated knife to gently cut the log in half, then cut each side of the log into six equal pieces. There will be 12 rolls.
Place the buns in a lightly greased 9x13 inch pan and press down slightly on each roll.
Cover the rolls and let rise for 1 hour until puffy.
Preheat the oven to 350º.
Bake the rolls for 20 to 25 minutes until they're golden brown.
Remove from the oven and let cool until slightly warm before icing.
