Cooking Channel is joining Food Network for our first annual cookie swap, 12 Days of Cookies. Each day, visit us here for a look at new holiday cookies, party-planning tips and top techniques for rolling, spooning, slicing, baking and decorating delicious sweet treats to give — or keep — from favorite chefs and Food People. Then visit FoodNetwork.com/12daysofcookies for great takes on holiday baking from Food Network chefs — cookies by the dozen to celebrate all season.

If you're going to pack a sandwich to work, it might as well be this one. Chuck Hughes sandwiches not one, but two shades of sweetness into his Chocolate and Caramel Shortbreads. Oozing with chocolate ganache and caramel, he finishes off the festive shortbread cookie sandwiches with a sprinkle of powered sugar.

The result? Two-toned towers of holiday deliciousness. It's no wonder he usually makes a second batch, just in case.
