I'm making a WASC, one box mix only but I need just a little extra batter than this will give me. I'd mix up another box...if I had one, but I can't get to the store right now. So, can I just add more flour/sugar/eggs? Help, please!

Please, oh please?

The only thing I can recommend is maybe making a small batch of homemade cake batter and adding it to your WASC...i'm not sure that you can further extend the recipe as it is without sacrificing some of the flavor..JMHO

Yeah, maybe search a cookbook for a basic white, yellow or pound cake recipe and mix it with what you already have. Can't guarantee what you will come up with, though.

I would get a small pound cake ingridients,mix like you normally would a pound cake,set aside and mix your regular WASC recipe,pour the two together and lightly mix together.
