if i make 1 boxed cake.. a 9x3, how many times can you tort that?
can you tort is 2 times?

I would think you could.....it all depends how straight you are and stuff.... I have seen my aunt torte a quiche pan cake......

I'm sure you could torte it twice. They'd just be thin layers. You could also add more batter to the pan to make a taller cake...say 1 and 1/2 boxes. The taller it is the easier it will be to torte and the more times you can torte it.
