The declaration in the title is from Cook's Illustrated magazine, source of this recipe. Vanilla sugar cookies are fine for cut-out cookies, but I am a chocoholic and these cookies are for me! :) Note that regular unsweetened cocoa powder will work in this recipe and instant coffee powder will also work in a pinch. The dough may be wrapped tightly in plastic wrap and stored in the refrigerator for up to 3 days or in the freezer for up to 3 weeks, Defrost frozen dough in the fridge overnight, then let stand at room temperature about 30 minutes until firm yet malleable. Cookies can be stored in an airtight container up to 3 days. Dust or glaze them the day they are served.
