Mix all in a mixer until a dough forms.
Place in a lightly oiled bowl and let rise 1 hour.
Deflate the dough and roll it on a floured surface into a 16" x 21" rectangle.
Spread the butter on the dough.
Combine brown sugar and cinnamon-then sprinkle it over the dough.
Starting at a short end, roll the dough up tightly and cut into 12 equal slices.
Place them in a greased 9" x 13" pan.
Cover and let rise 30 mins.
Bake at 400 degrees for 15-20 minutes until golden.
