The sooner the better! Keep the bar's last though only because I have noticed that they don't taste as fresh! I think I usually start about 2 weeks before Christmas although I may start a bit earlier only because I love sending them in festive baskets as gifts for our neighbor's...Here's a family favorite and have never had a complain about these bar's..Guarantee you'll LOVE them! Warning; they are extremely addictive! Here's the link---- http://www.landolakes.com/recipe/2237/chocolate-drizzled-...
Hope you have a wonderful Holiday season!
