In a bowl, mix together the brown sugar, cinnamon, flour, and salt.
Once the dough has risen 40 minutes, transfer to a floured surface (see video for my Dexas Superboard Pastry Board). Fold dough over itself 4 times (see video). Roll out to a 12x15 rectangle.
Spread the softened butter all the way to edges of the dough except for the top edge. (We will use this small un-buttered area to seal the rolls later on.)
Sprinkle the cinnamon sugar mixture evenly over the buttered dough. Starting at the bottom edge, roll the dough upward somewhat tightly into a log shape, and pinch the un-buttered edge to seal the log (see video).
Time to cut the rolls using a sharp knife! This recipe will make 4 giant cinnamon rolls, 6 large, or 12 muffin sized rolls. Below are pan sizes for each choice:4 Giant Cinnamon Rolls: Line an 8 inch square pan with parchment paper. Arrange rolls evenly, cover and let rise in a draft free area for 20 minutes.6 Large Cinnamon Rolls: Line a 7x11 inch pan with parchment paper. Make 2 rows of 3 rolls to fit the pan. Cover and let rise in a draft free area for 20 minutes.12 Muffin Sized Cinnamon Rolls: I like to bake the muffin size rolls in a muffin pan. Line each muffin cup with a parchment tulip liner (or any parchment cupcake liner of your choice. I like using parchment because it is non stick. No need to grease the parchment liners.). Cover and let rise in a draft free area for 20 minutes. Once the rolls have risen, place in a preheated 375 degree oven for about 20 minutes. Baking times may vary depending on your oven. I baked mine in a convection oven. A standard oven may take a little longer on the larger rolls. Make sure to bake the rolls long enough. They will turn a nice browned color as they bake. You can test the middle of a cinnamon roll for doneness by lifting up the center of a roll. You don't want a doughy roll! Keep close check on your hard work as they bake. As the rolls bake, you can mix the glaze.
