Besides Christmas cookies, try some other treats to serve at your hot cocoa station. A bowl of pretzels makes a nice salty sweet combination. Cheddar cheese and crackers makes a hearty snack and also pairs well with chocolate. Tangy fruits, like grapes, oranges, Granny Smith apples, pears, strawberries, raspberries or cherries are refreshing and will cleanse the palette. If you're not afraid of chocolate overload, offer some chocolate candies, too.
