Can I use a stoneware 9x13 pan instead of a metal 9x13 pan for Caramel Rolls?
If your caramel rolls are the kind with a sticky, gooey mass in the bottom of the pan that is flipped upside down out of the pan, then I would say that the rolls won't really get good and caramely in a stoneware pan. You'd be better off baking one pan of rolls at a time in the metal pan. While one pan is rising and baking, just chill the other part of the dough... either plain in a bowl, or prepared into a log that only needs to be cut.

If the caramel rolls are more like a cinnamon bun, then the stoneware dishes should do fine in a pinch. This is assuming they are glazed stoneware and not terra cotta. Cooking time will increase a bit as the stoneware will take longer to heat up (it will also retain the heat longer when removed from the oven).

You could always just go out and buy some foil pans. I do that when I make rolls (caramel, cinnamon, and sticky) for the local fire company's carnival. They go through 17=20 dozen rolls each year.

I know baking rolls can be a lot of work, so what I have found to be very helpful, is to make the dough the night before baking. Cover with cling film, and let it have a slow rise in the fridge all night. (you will get improved flavor too.) The next day, divide the cold dough up and prepare as usual. They will take a little longer for the rise in the pan after shaping, but it sure is a lot easier on you.
