These easy decorated Halloween sugar cookies with royal icing look like you spent hours, but come together with smart shortcuts. The royal icing sets up perfectly glossy, the cookies hold their shape, and the decorating is the best part—no piping bags required if you don’t want them.
Don’t skip the chill time—warm dough spreads. Flour your rolling pin and surface lightly. Use the 15-second test for icing consistency. Work in batches when decorating. Keep a damp paper towel over icing bowls to prevent crusting. Let cookies dry at room temperature—do not use a fan. Cookies taste better the next day. Store undecorated cookies up to 2 weeks; decorated cookies up to 1 week. Freeze unbaked dough or baked undecorated cookies for up to 3 months.
