someone was going to ask this, pdswife!
Nope - biscuits are a dough - cornbread is a batter. About all you can do is make cornbread muffins in muffin tins, scoop out the centers, and fill them with chili.
Paula's recipe is really a "presentation" and not a "flavor" thing - one of the recipes I think she really blew it on (but I'm from Texas and our taste in chili is a little different than Albany, GA). Make a skillet of cornbread, crumble it up in the bottom of a bowl, pour chili over ... it ain't as cute or purty - but it'll taste better, IMHO.
