- Make the filling by mixing together the softened butter, brown sugar, and cinnamon. 
- Add baking soda, baking powder, and salt to the dough. Mix with the dough hook or your hands for about 5 minutes. 
- Scrape the dough out onto a lightly floured surface. Using a rolling pin, roll a large rectangle that's about a quarter of an inch thick. 
- Evenly spread the filling over the top of the dough, leaving a little space on each long side to pinch the seam together. Then slowly roll the dough up, as tightly as you can.  
- Cut the dough into equal pieces using thin string, unflavored floss, or a very sharp knife.  
- Arrange the cut rolls into a 14-inch cast iron skillet or glass baking dish, and pour cream over all the rolls. (optional) Cover with a tea towel, preheat the oven to 375, and do a final rise for about 30 minutes. 
- Bake in the 375 degree oven for 22-25 minutes.
