These mummy sugar cookies are tender, buttery, and decorated with a perfect royal icing that sets hard and shiny. Easy enough for beginners but rewarding for experienced bakers, they’re the cutest Halloween treat on the block.
For best results, chill dough at least 1 hour to prevent spreading. Royal icing should be 15-second consistency. Do not ice warm cookies. Store in airtight container at room temperature for up to 1 week. Freeze undecorated baked cookies for up to 3 months.
