Our DS is in cub scouts and has a father son cake contest next week. We have a decorating design of a reproduction of the pinewood derby, but can't seem to come up with a cake recipe that DH and DS both agree with. They don't want plain chocolate or white cake, but the cake has to be pretty sturdy for us to stack, to be able to make the race track out of. I am a box cake mix baker only and I am not supposed to help them any how, so they are on their own. Does anyone have a simple but yummy cake recipe two guys could probably handle?
