I have not tried this recipe but was given this by a co-worker with a suggestion that I might need to try it "hint hint". So I have posted it so I will not lose it. It is supposed to be an extremely moist cake and I plan to use some of the instant mashed potatoes to make it. Update: I have made this cake and it is a very dense cake. Almost like a big brownie. My co-workers loved it but this is not a light, fluffy cake.
