Grease a standard 9x5 inch loaf pan and line the bottom with parchment paper.
Punch down and roll the dough on a lightly floured surface, into a large rectangle, about 9x15 inches. Spread the cinnamon apple butter over the dough, leaving a 1 inch border around the bread.
Sprinkle pecans or walnuts over the cinnamon apple butter, if using. Roll from the short end, roll into a tight log.
Using a sharp knife, cut the log lengthwise, keeping one end attached. Twist the two pieces together and carefully place the bread in the prepared loaf pan.
Place loose plastic wrap over the bread and let it double in size, about 30 minutes. Preheat oven to 350°F (177°C).
Remove the plastic wrap and bake uncovered for 30-40 minutes until lightly browned and 190°F (88°C). If the loaf is browning too quickly, tent it with aluminum foil.
Cool the loaf on a wire rack for about 20 minutes. Remove from pan and allow it to cool completely before slicing into it.
Store leftover bread tightly wrapped up at room temperature for up to 2 days.
