I am doing a car cake for a grooms cake next week and cannot find a chocolate version of a good tasting and dense enough cake that it's good for carving like the WASC. I am stressing enough about the cake that I want to at least find a good recipe. Thanks in advance.

OK, after doing some further research from other forum posts the WASC and chocolate version of it did not hold up to carving... too moist and crumbly. Would a pound cake be better then? Anyone have any good recipes for that?
