When dough has risen, remove cover and, using your fist, punch the dough down and remove from the bowl. Roll out on a well-floured surface into a 12x18 inch rectangle. Spread the 2 tablespoons of melted butter almost out to the edges, but not quite.
Mix sugar and cinnamon together to create the filling. Sprinkle filling evenly over the melted butter. I use a spoon to help me do this. Gently begin to roll the dough from the long end to the other, tucking the dough tightly and evenly. You should end up with a log 18 inches long.
Grab a large baking sheet and place parchment paper on top. Place the cinnamon roll log on top of baking sheet, uncut and seam-side facing down. Using a serrated knife, cut the dough into 20 pieces, making sure NOT to cut all the way through. Lay each roll on its side in the same direction and gently begin to form log into a wreath. Place ends on top of each other to seal the wreath. Adjust each roll so it is facing up. You may have to cut the rolls a little more to move them the way you want them to go. Also, you may have to make the wreath into an oval to fit onto the baking sheet, like I did. Remember, it will rise during the second proofing and baking so you want to give it enough room from the edge of the pan. While you were adjusting the log into a wreath, the seam may have become exposed. Make sure to tuck it back under so it doesn't unravel more during baking.
Add an oven-proof ramekin or small bowl to center to keep it perfectly round. Cover with plastic wrap or a towel and let rolls rise again until doubled, about 1.5 hours. Some doughs may take less so just keep and eye on it. With about 20 minutes left in the rising process, preheat oven to 350 degrees.
When the wreath has finishing rising, bake for 23-25 minutes until deep golden brown. Remove from oven and let cool for 10 minutes before icing.
