Homemade cake icing can last for varying amounts of time depending on the type of icing and storage conditions. Generally, buttercream frosting can be kept at room temperature for about three days.
Here's a more detailed breakdown:
Buttercream Frosting
- Room Temperature: Buttercream frosting, primarily made with butter, sugar, and milk, is typically safe to store at room temperature for about 3 days (72 hours). The high sugar content acts as a preservative.
- Refrigerated: For longer storage, refrigerate buttercream frosting. It can last for up to 1-2 weeks in the refrigerator. Be sure to store it in an airtight container.
- Frozen: Buttercream frosting can also be frozen for 2-3 months. Thaw it in the refrigerator overnight before using. You may need to rewhip it to restore its original consistency.
Cream Cheese Frosting
- Refrigerated: Due to the dairy content, cream cheese frosting should always be stored in the refrigerator. It is best to use it within 5-7 days.
- Freezing is not recommended as it can affect the texture.
Other Types of Frosting
- Cooked Frostings: Like Seven-Minute Frosting or Ermine Frosting should also be refrigerated. Follow similar guidelines to buttercream: 5-7 days refrigerated.
- Ganache: Can be stored at room temperature for 2 days if made with pasteurized cream, or refrigerated for up to 1 week.
Tips for Storing Icing
- Airtight Container: Always store icing in an airtight container to prevent it from drying out or absorbing odors.
- Cool Completely: Allow the icing to cool completely before storing it.
- Label and Date: Label the container with the type of icing and the date it was made.
- Check for Spoilage: Before using, check the icing for any signs of spoilage, such as an off odor, discoloration, or mold.
By following these guidelines, you can ensure that your homemade cake icing stays fresh and delicious for as long as possible.
