Baking on a cookstove with Cast iron? I make flour tortillas in my skillet on the stovetop at home regularly.

However, if you have a bag of charcoal, you can bake anything using a dutch oven. Even just a good wood fire out back will do in a pinch. Got a charcoal grill? It'll work just fine as a firepan. Those square portable ones you see at Walmart and Home Depot for $30 to $50 make excellent firepans. A 20 lb bag of charcoal in the garage will do you at least 4 to 7 pots of fresh baked bread or biscuits or dump cakes or what have you.

Sometimes you gotta think outside the box, er, house.
