cornbread in the oven

OK guys I do not have a thermabaker, so that is not an option.

Has anyone made cornbread on retained heat in the oven??
If so, what worked for you?

I do have the original Idle Hour Cookbook for the "B" model. It does not have anything similar to go by.

I'm working on a Mexican Cornbread recipe.

Thanks for any help or input.
