Last night I had a craving for cake, and since I didn't have any eggs I used the "Wacky Cake" recipe posted in this thread http://chowhound.chow.com/topics/506749 by Sarah Galvin and subbed flour for chocolate, as suggested in that thread. It smelled great in the oven, came out and tasted okay, if a little off. Somehow, though, by the time it cooled it started to taste disgusting- it's way too oily, and it has an off, vinegary taste. To make matters worse, I tried out a new roux-and-whipped butter/sugar recipe for frosting that also came out badly- it separated and looks lumpy and unappetizing, not fluffy and glorious as it should.
So. Is there anything I can make a bad cake into so that all the ingredients aren't wasted? I have a 9x13 pan of it and I doubt even my boyfriend will be willing to eat it (the dog loves it but he only weighs 8 pounds). It has a great warm brown color but a coarse crumb, and it's just very oily and not flavorful.
