We tried it last night... yeah quite nice. To be honest it just tasted like chocolate cake, with maybe a little smoky aftertaste? So honestly I'd prefer just normal chocolate cake, I don't feel the stout and mustard added anything to improve the cake.Share your experience - I'm interested. The stout sounds very appealing - not sure how the mustard affects flavor...
I guess it would depend on just how much stout and mustard were in the cake, but I don't feel it enhanced the classic chocolate cake hehe.
