This eye-catching frozen peppermint-chocolate bark was inspired by williams sonoma's original peppermint bark--our loose interpretation of the treat is frozen and made with greek yogurt, chocolate and crushed candy canes. For the creamiest bark, be sure to use full-fat yogurt, as fat-free yogurt can get icy when frozen. Serve this healthy dessert when you want all those festive holiday flavors in a lightened-up--and totally delicious--package. Just don't stuff your christmas stockings with this bark because it melts quickly.
