If you've got the set, according to this, each pan uses 5 1/2 cups of batter which is about a mix.

If you're doctoring your mix like the Original WASC recipe here on CC than I'd guess you probably get 1 1/2 mixes worth of batter and could probably just use a double recipe for this pan set.
Thanks for the quick replies. I used the pan today and made two doctored mixes and found I had just a little left over (so I think you were all right on target!)
I will have to wait to see how it looks when cut to determine how well the pans worked for me.
Thanks again!
