The cornbread dressing that we always have had around my house (parents' house- I haven't hosted a Thanksgiving at my place yet... :p) IS basically a savory bread pudding. Take day-old cornbread (be sure you don't use the sweet kind that some people think is the way to go), biscuits too if you feel like it, and grind all that up into a medium coarse powder/crumble, then add eggs and some turkey drippings, sage and poultry seasoning to taste. Dump in a big roasting pan, bake until set and the top is the level of GBD that you like.
Tada- dressing. I don't know on the cream- that sounds a little off to me. We always just use the turkey drippings (it doesn't take much) as the liquid in ours- the rest gets turned into giblet gravy, which then goes on top of the dressing.
It's my favorite food.
