A simple and quick frosting made with just powdered sugar and milk that hardens to a perfect, crackly finish, ideal for decorating sugar cookies.
Sift powdered sugar before mixing to avoid lumps. Use cold or room temperature milk to prevent runny frosting. Spread on cooled cookies only. Adjust thickness by adding powdered sugar or milk as needed. For detailed decorating, use a piping bag. Store frosted cookies in an airtight container at room temperature for up to 5 days. Freeze with parchment paper between cookies if longer storage is needed.
