If I add a box of pudding to my WASC recipe will that make it a bit more durable for carving? I want the volume of the WASC (one box mix size) but have found it a bit fragile for carving. I need to make a purse for Friday. It doesn't require intricate carving, but I have had some issues in the past.

That should definitely help. I would also recommend carving it while it's still semi-frozen, or at least chilled very well.

It's easier if you carve the WASC cake frozen.

I've found it makes a difference whether you use a straight knife or serrated. I don't hardly ever freeze mine.

Malakin, Which do you find better? Straight or serrated? Not sure I have time to freeze it.

I added a box of sugar free cook and serve pudding and it really seemed to help. I only had sugar free on hand so I didn't use instant since it had nutrasweet in it and that can't be heated.

I always carve mine semi-frozen with a straight edged knife - I find that a serrated just chews it up too much.
