Turn the dough onto a sheet of parchment paper. Using a rolling pin, roll it into a rectangle about 24 inches long.
Spread the softened butter evenly over the dough. In a small bowl, mix the brown sugar and cinnamon, then sprinkle the mixture over the buttered dough.
Starting at one end, roll the dough up tightly, tucking in the ends and pinching to seal.
Slice the roll into ½- to 1-inch sections—you should get about 12 rolls. Place them on a sheet of parchment paper for about 30 minutes to rise while you prepare the pecan topping.
Add the chopped pecans to the bottom of a 9X13 casserole dish.
In a small saucepan over medium heat, combine the butter, brown sugar, milk, syrup, and salt. Stir constantly and let the mixture simmer for about a minute. Remove from heat and pour over chopped pecans.
Bake in a preheated 375°F oven for about 25-30 minutes or until golden brown. Remove from the oven and let the rolls cool for 5 minutes.
Using oven mitts, place a serving tray or baking pan on top of the casserole dish and carefully flip the casserole dish over letting the buns slide out onto the tray. Be careful as the topping will be hot.
Remove the casserole dish and scrape any leftover pecans still in the casserole dish on top of the buns.
Let them sit for a few minutes before serving.
