Cut each biscuit into four pieces (you can do this quickly by stacking several on top of each other, cutting through them all at once, then separating). Mix sugar and cinnamon in zip-lock bag. Add biscuit quarters and shake until all are coated well. You can do this part ahead of time if you like and have ready.
Place the coated biscuit pieces in the bottom of the Dutch oven. Melt butter in lid of Dutch oven and then pour over the biscuit quarters. Put 6-8 coals underneath Dutch oven and 14-15 on top. Bake for 30 minutes.
