Beets with chocolate? I find that to be sacrilegious.
I have tried similar recipes where squash was substituted for apples in Apple Pie. It was rather.. Well.. Not good... I haven't tried the beets in chocolate cake but I don't think it will be on my menu any day soon. Who knows, you may enjoy it.
Never imagined beets with chocolate before. But it does looks delicious. Would have to give it a try someday.
