Make your own ice cream sandwich

I know ice cream sandwiches make you think of summer.  However, I've been thinking that an ice cream sandwich bar at a holiday party could be quite cute.  Especially if you switch up the ice cream flavors to be holiday-ish.  You could do any number of fun combos for the cookie part.  It's easy, requires no oven time and you can make it fit into any holiday theme depending on what bowls and such you use.  Personally, I love the idea of munching on a cinnamon graham cracker plus pumpkin bourbon ice cream combo which I think would taste unbelievable with champagne.  If you are having trouble coming up with a dessert, this might just be the fun touch you needed.
