One I like - take the Toll House recipe on the back of the bag. Instead of dark chocolate, use white chocolate chips. Add orange zest and a little cinnamon to the batter. Add in dried cranberries, and some chopped nuts. Easy enough, but the flavor is slightly different and festive.

This shortbread base if very easy. See the links to pick the topping flavor:
