4. Ice the Cookies:
- Spread approximately 1 tablespoon of icing onto each cooled cookie. Allow the icing to set before serving.
5. Storage:
- Store the cookies in an airtight container with parchment paper or foil between layers to prevent sticking. They can be kept at room temperature for 4-5 days or refrigerated for up to a week. For longer storage, the cookies freeze well if wrapped tightly.
