Carton egg whites

[mummybear701]

I'm looking to try baking cakes that call for egg whites only. I know cartoned whites are not advisable for meringue or frosting, but does it work for cakes mixed with butter, flour and sugar?

I use cartoned egg whites for meringue and they are lovely. I always have a carton in the fridge. I use them for anything asking for egg whites, cakes too.
