Yes, Johnie. I used to beg my Mother to not frost the cakes... every now and then she'd make one that was really dense and moist that didn't 'need' frosting. As far as I'm concerned no cake needs frosting! LOL.
But RV is very moist and would be great without frosting.
Lard is the only thing that I could think of that looks like the product. It's NOT a replacement as I said, but I was trying to give you a mental image. Crisco is smoother and creamier than lard.
