For best flavor, use a high-quality instant espresso powder that dissolves easily and avoid brewed coffee which adds excess liquid; chilling is essential for clean slicing and preventing spread, so don’t skip it. If the dough seems greasy or too soft, chill it briefly between steps, and if it seems dry and sandy, a teaspoon of milk can help it come together without overmixing. Bake one test cookie to gauge timing, as ovens vary, and pull them when edges barely color for a tender bite. These keep well in an airtight container for 5 to 7 days, and the dough can be frozen up to 2 months; slice and bake from frozen, adding 1 to 2 minutes to the bake time.
