The following morning, line your 8" square baking pan with parchment paper.
In a small mixing bowl mash together the butter, sugar and cinnamon until you have a smooth flavored butter paste.
Remove the dough from the refrigerator and scrape out of the bowl onto a well floured work surface.
Press this into a rectangle and then roll it out until it is about 12" wide by 15" long.
Spread your cinnamon sugar butter over the surface of the dough, leaving a small gap around the edges.
Sprinkle the chocolate chips over top.
Roll the dough from the bottom to the top forming a tight log.
Using flavorless dental floss or thin kitchen twine, trim about an inch or so off both ends of the log, removing the uneven and unfilled dough.
Then divide the remaining log into 9 pieces, slice these with the floss and place them in your lined baking pan.
Cover with a clean kitchen towel and allow to proof at room temperature for about 2 hours, until doubled in size.
