Deep, dramatic black cocoa sugar cookies that hold their shape perfectly for royal icing decorating. These Halloween cookies are soft in the center, crisp at the edges, and taste like a grown-up version of a classic sugar cookie with a rich, slightly smoky chocolate flavor.
Chilling the dough is non-negotiable to prevent spreading. Black cocoa powder is essential for the deep black color; Dutch-process cocoa will result in dark brown. For best results, use a food scale for the cocoa powder. Cookies taste even better the next day as the black cocoa flavor deepens. Royal icing needs at least 4 hours to dry completely before stacking.
