Roll out the dough to about 3/16" thick. If it is difficult to roll out and keeps shrinking back, let it rest for a few minutes before trying again.
Trim the edges off the dough to form an even rectangle.
Combine the 3/4 cup sugar and the ground cinnamon together in a small bowl. Sprinkle the mixture over the dough, leaving a small 3/4 in border at the edge.
Roll the dough up tightly into a log. Slice it into 2 inch wide pieces - you should get about eight pieces.
Place the pieces upright (like a wheel), seam side down, on a baking sheet lined with either parchment paper or silicone baking mat, about 2 inches apart. Using the handle of a wooden spoon or a chopstick, press down into the middle of the roll to squash the roll down and make the sides fan out. Do not press all the way down and split the roll.
Brush the tops of the rolls with egg wash and let them proof on the tray for about 2 hours, until the rolls have doubled in size and look puffy and light.
While the rolls are rising, preheat the oven to 375 degrees F.
Brush another layer of egg wash over the rolls and bake for 15-20 minutes until they are golden brown.
