Drum roll please...
Ta-dah! Red wine and dark chocolate.
Not exactly your grocery-store variety of oatmeal cookie, but I think it might be worth a try. Apparently, red wine and dark chocolate are two flavors that pair well together. So why not? This could be a cookie for adults.
I'm no wine expert. In fact, I'm not even a drinker. Just the smell of alcohol makes me do that scrunched-up "ick, booze!" face. (I know...I'm no fun at parties.) But I think cooking down and reducing the wine will burn off some of its alcohol and leave behind a velvety grapiness to complement the richness of the dark chocolate.
