It's Day 10 of #25DaysOfCookies! ‘Tis the season for whimsical, festive treats like our @CooksIllustrated Vanilla Icebox #Cookies. We found that the key to the perfect texture was to use two types of sugar: granulated sugar and confectioners’ sugar. The granulated sugar gives the cookies some structure and a good snap, while the confectioners’ sugar ensures tenderness. We like to roll the chilled dough logs in sprinkles, colored sugar, or chopped toasted nuts.
