Is it the same as adding "veg oil"?
i'm looking at a Whoopie pie recipe - they seem very similar to reg chocolate cakes.

yes it is going to be the same purpose, but your results are going to differ a little, a cake made with shortening is going to be a little firmer (as short. is firmer than oil) and may leave a greasy residue in your mouth.

thanks!

ew... it's bad enough to get it from the icing. I usually use butter instead of veg oil.
