Pour melted butter into a wide, shallow bowl and set aside. Mix granulated sugar and cinnamon in small bowl. Pour about 1/3 of the sugar mixture into a wide, shallow bowl. Set aside. Grease or parchment-line two baking sheets.
Turn the dough out on a lightly floured surface and divide it into 24 evenly-sized pieces (if you did not refrigerate the dough, you might need more than a light dusting of flour).
Working one at a time, roll each piece of dough into a 10 to 12-inch rope, using just enough flour to prevent sticking. Before shaping, lightly dust the rope with flour, and then, with floured hands, turn it into a pumpkin.
Create a small loop in the rope with a long tail on one side and a short tail on the other.
Wrap the long tail around the edge of the loop 2 to 3 times.
Hold the remaining end of the long tail on the bottom-side of the loop with a finger to keep it from unraveling as you to work.
Wrap the other tail around the edge of the loop, tucking it through the center of the loop and pinch the two ends together where they meet on the bottom side.
If you’re not happy with the look of any of the rolls, simply set them aside for about 15 minutes and reshape.
Working one at a time, dip the shaped buns into the melted butter, turning for even coverage. Dredge the buns in the sugar mixture to coat them completely, jostling gently to work some of the sugar under the folds of dough.
Transfer the sugar-coated buns to the prepared baking sheets.
As needed, add more cinnamon-sugar to the wide, shallow work bowl, whisking to combine and break up buttery clumps.
Insert a sliced pecan into the center of each roll, pressing so the pecan touches the pan.
Cover the rolls with lightly oiled plastic wrap and let them rest at room temperature for 20 to 30 minutes. In the meantime, preheat oven to 375°F.
Bake the rolls until they have an internal temperature between 190 and 200°F, about 20 to 25 minutes.
Let the rolls rest for 15 to 20 minutes before eating.
To reheat, set rolls in an oven preheated to 300° F oven for about 10 to 15 minutes.
