Home Baker here. I made the Wooley cake. (It was posted over on Cooks Talk.) I made it in a 9 X 13 pan, with powdered buttermilk, and natural organic cocoa. (Can't remember the brand...it's not my usual kind, but it was on sale.) Steamed it by covering the pan with its metal cover, refrigerated over night (didn't freeze it). I hate to disagree with everyone, but I didn't think it was that great of a cake - probably just a 3.5. My husband, who adores cake, bit into it and said, "eh. Tastes like cake." There was no clambering for more. I definitely think it does achieve the "cake mix" texture and mouth feel. (Even the uncooked batter reminded me of cake mix batter.) And, it absolutely disappeared at the potluck for which it was made. (Unfortunately, I didn't know anyone there that ate it, so I didn't get additional feedback.) The chocolate cake recipe I've used in the past was one that incorporated mayo. I don't have it on me now, and I haven't made it recently, so maybe I remember it as better than it is. But, I could post it later if anyone wants to try it.
