In Australia, it's not cheap or that easy to buy Duncan Hines cake mixes. Is there an alternate that I can use for the WASC recipe? Would any white cake mix work from a reputable brand?
Try the scratch WASC recipe from here on CC. It's the one I use and it's great - and cheaper than using a boxed mix. I think one of the reasons so many Americans use boxed mixes is because they're so cheap over there. I have an American friend who lives here now and she nearly fell over when she went to buy a standard boxed cake mix.
Anyway, the scratch WASC is very good. There's also a long thread on the recipe with lots of good advice and variations. I find the only thing I need to change is that I don't use as much milk as the recipe calls for.
The Duncan Hines classic white cake mix is 18.25 oz. or 517 g:
Here are the instructions (if you were going to make just the standard box mix just to give you a reference point as to how much batter it yields) with different pan sizes and baking times:

Ok another question - what portion of the white cake recipe would I use to replace the Duncan Hines part of the recipe?
