How to Store It

Before using refrigerated icing, let it soften and stir it thoroughly. If it becomes too thick, adjust the consistency with more milk as needed. This icing is best used fresh for decorating. Freezing is not recommended because it may affect the smooth texture and consistency.

Helpful Tips

  3. Decorate cooled cookies: Make sure the sugar cookies are completely cooled before applying the icing to help it set properly.
  4. Work in small batches: Keep unused icing covered while decorating to prevent it from drying out.

Optional Variations
