Prep the pans: Grease two loaf pans with oil and line with parchment paper, leaving a couple of inches of overhang on the long sides.
Remove the dough from the bowl and put it on a lightly floured surface. Using a sharp knife or dough scraper, cut the dough in half. Work with only half of the dough at a time. Place a clean towel over the dough you aren’t working with so it won’t dry out.
Roll one piece of dough into a rectangle as wide as the length of your loaf pan and about 3/4 inch thick. Spread the chocolate filling on the dough in an even layer all the way to the edges. Tightly roll up the dough like a jelly roll and place it on its seam. Repeat with the 2nd half of the dough.
*Optional* I've found that freezing the logs for 20-30 minutes makes the slicing much easier.
Use a sharp knife or a dough scraper to slice the log in half lengthwise so you have two long pieces, and set them with the chocolate layer exposed. Twist the logs together, keeping the cut sides facing up. Transfer the twisted dough to the prepared loaf pan and cover it with a clean towel. Repeat with the 2nd half of the dough.
