pls , can anyone help with a better explanation of how to use whipped margarine for baking? just want to try it.

Sure.

Don't.

It really just isn't suitable for baking, as all the air that's whipped into it messes up the measurements.  Also, there's a fair amount of water in margarine, so that affects recipes also.  It's better to use whatever the recipe calls for - butter or veg shortening.  

thanks!
