Leftover icing. The bane and blessing of every baker’s existence. It represents both the delightful memory of a perfectly frosted cake and the nagging question: what do I do with it now? Can you actually save leftover icing? Absolutely! But the real trick lies in knowing how to save it properly to maintain its flavor and consistency. This guide will walk you through everything you need to know to become a leftover icing master.
Understanding Icing Types and Their Storage Implications
Not all icings are created equal, and their composition heavily influences how well they store. Understanding the fundamental differences is crucial for optimal storage.
Buttercream Icing: The Queen of Frosting
Buttercream is perhaps the most popular icing choice, known for its rich, creamy texture and versatility. It’s typically made with butter, powdered sugar, and milk or cream. There are variations, like American buttercream, Swiss meringue buttercream, and Italian meringue buttercream, each with slightly different ingredients and techniques.
The key ingredient here is, of course, butter. Butter is a dairy product prone to spoilage if left at room temperature for extended periods. Therefore, proper storage is essential to prevent bacterial growth. Buttercream generally holds up well in the refrigerator, but can become quite firm.
Cream Cheese Icing: Tangy and Tempting
Cream cheese icing is another favorite, boasting a tangy flavor that pairs beautifully with cakes like red velvet or carrot cake. It includes cream cheese, butter, powdered sugar, and vanilla extract.
Cream cheese, being a dairy product, also demands careful handling. Like buttercream, it needs refrigeration to prevent spoilage. However, cream cheese icing tends to be even more prone to absorbing flavors from its surroundings, so airtight storage is especially important.
Royal Icing: The Art of Decoration
Royal icing is a hard-drying icing primarily used for decorating cookies and creating intricate designs. It consists of powdered sugar, meringue powder (or egg whites), and water.
Unlike buttercream and cream cheese icing, royal icing does not require refrigeration. Its high sugar content acts as a preservative, making it shelf-stable. However, it’s crucial to prevent it from drying out, which can make it unusable.
Other Icing Variations
Beyond these main types, you’ll encounter variations like ganache (chocolate and cream), fondant (sugar paste), and glazes (thin, pourable icings). Each has its own storage considerations, but the principles outlined for buttercream, cream cheese icing, and royal icing generally apply. The presence of dairy significantly shortens the shelf life, while high sugar content extends it.
The Correct Methods for Storing Leftover Icing
Now that you understand the different types of icing, let’s dive into the nitty-gritty of storage techniques.
Refrigerating Buttercream and Cream Cheese Icing: The Chill Factor
Refrigeration is your best friend when it comes to buttercream and cream cheese icing. Here’s the process:
-
Transfer to an Airtight Container: This is paramount. Use a container with a tight-fitting lid to prevent the icing from drying out and absorbing odors from the refrigerator. A good quality plastic container or glass jar works well.
-
Smooth the Surface: Use a spatula to smooth the surface of the icing. This helps prevent a skin from forming.
-
Optional: Cover with Plastic Wrap: For extra protection, press a piece of plastic wrap directly onto the surface of the icing before sealing the container. This creates an additional barrier against air.
-
Refrigerate Promptly: Don’t leave the icing at room temperature for more than two hours. Refrigerate as soon as possible.
Buttercream and cream cheese icing can typically be stored in the refrigerator for up to a week.
Storing Royal Icing: Keeping It Moist
Royal icing storage focuses on preventing it from drying out.
-
Airtight Container is Key: Similar to buttercream, transfer the royal icing to an airtight container.
-
Damp Paper Towel (Optional): Place a slightly damp paper towel directly on the surface of the icing to help maintain its moisture. Be careful not to make the paper towel too wet, as this can affect the icing’s consistency.
-
Seal Tightly: Ensure the container is tightly sealed to prevent air exposure.
Royal icing can be stored at room temperature for up to two weeks. If you live in a particularly humid environment, you may want to refrigerate it to prevent mold growth, although this can sometimes affect its texture.
Freezing Icing: A Long-Term Solution
Freezing is a viable option for longer-term storage of buttercream and cream cheese icing.
-
Use a Freezer-Safe Container: Choose a container specifically designed for freezing. These are typically made of thicker plastic and are less likely to crack in the freezer.
-
Consider Portioning: If you know you’ll only need a small amount of icing at a time, consider freezing it in smaller portions. This prevents you from having to thaw and refreeze the entire batch.
-
Double Wrap for Protection: Wrap the container in plastic wrap and then aluminum foil for extra protection against freezer burn.
-
Label and Date: Always label the container with the date and the type of icing.
Frozen buttercream and cream cheese icing can last for up to three months.
Reviving Stored Icing: Bringing It Back to Life
So, you’ve successfully stored your leftover icing. Now comes the crucial part: reviving it to its former glory.
Reviving Refrigerated Buttercream and Cream Cheese Icing: The Thawing and Whipping Process
Refrigerated buttercream and cream cheese icing tend to become quite firm. The key to reviving them is to bring them back to a spreadable consistency.
-
Allow to Thaw: Remove the icing from the refrigerator and let it sit at room temperature for at least 30 minutes to an hour, or until it softens slightly. Do not microwave.
-
Whip It Good: Once softened, use an electric mixer to whip the icing until it becomes light and fluffy again. This process incorporates air and restores its creamy texture.
-
Adjust Consistency: If the icing is still too thick, add a teaspoon of milk or cream at a time until you reach the desired consistency. If it’s too thin, add a tablespoon of powdered sugar at a time.
-
Taste Test: Give the icing a taste test and adjust the flavor as needed. You may want to add a pinch of salt, a drop of vanilla extract, or a squeeze of lemon juice.
Reviving Frozen Buttercream and Cream Cheese Icing: Patience is a Virtue
Reviving frozen icing requires a bit more patience.
-
Thaw in the Refrigerator: The best way to thaw frozen icing is to transfer it to the refrigerator and let it thaw overnight. This allows for a slow, even thaw, which helps maintain its texture.
-
Whip It (Again): Once thawed, follow the same whipping and adjusting process as described for refrigerated icing. You may need to whip it for a longer period to fully restore its texture.
-
Don’t Refreeze: Once you’ve thawed and revived the icing, it’s best not to refreeze it, as this can further degrade its texture.
Reviving Royal Icing: Adding Water Dropwise
Royal icing tends to dry out, even when stored properly. Reviving it involves rehydrating it.
-
Add Water Gradually: Add a few drops of water at a time to the icing, mixing well after each addition.
-
Achieve Desired Consistency: Continue adding water until you reach the desired consistency. For piping, you’ll want a thicker consistency. For flooding cookies, you’ll want a thinner consistency.
-
Be Patient: It’s better to add too little water than too much. Add water gradually and mix thoroughly to avoid over-thinning the icing.
Troubleshooting Common Icing Problems After Storage
Even with the best storage practices, you might encounter a few hiccups. Here’s how to troubleshoot common problems.
Icing is Too Thick
This is a common issue, especially with refrigerated or frozen icing. As mentioned previously, add a teaspoon of milk or cream at a time (for buttercream and cream cheese icing) or a few drops of water at a time (for royal icing) until you reach the desired consistency.
Icing is Too Thin
If you’ve added too much liquid, add a tablespoon of powdered sugar at a time until the icing thickens up.
Icing is Grainy
Graininess can occur if the butter in buttercream icing separates or if the powdered sugar doesn’t fully dissolve. Try whipping the icing for a longer period to re-emulsify the butter and dissolve the sugar. You can also try gently heating the icing over a double boiler while whisking constantly. Be careful not to overheat it, as this can cause the butter to melt completely.
Icing Has Absorbed Flavors
Icing, especially cream cheese icing, can absorb flavors from the refrigerator. To mask these flavors, you can add a stronger flavoring agent, such as vanilla extract, almond extract, or lemon zest.
Icing Has a Skin on Top
This is a common occurrence with refrigerated icing. Simply remove the skin before whipping the icing. The icing underneath should be perfectly fine.
Tips for Preventing Icing Spoilage
Prevention is always better than cure. Here are a few tips to minimize the risk of icing spoilage.
- Use Fresh Ingredients: Start with fresh, high-quality ingredients. Expired butter or cream cheese will result in icing that spoils more quickly.
- Proper Food Handling: Follow proper food handling practices to prevent contamination. Wash your hands thoroughly before handling ingredients and use clean utensils.
- Don’t Double Dip: Avoid double-dipping into the icing with used utensils, as this can introduce bacteria.
- Store Promptly: As mentioned earlier, don’t leave icing at room temperature for more than two hours. Refrigerate or freeze it as soon as possible.
- Use Airtight Containers: Invest in good quality airtight containers to prevent drying out and flavor absorption.

Can all types of icing be saved?
Generally, yes, most types of icing can be saved, but the success depends on the ingredients and how it was originally prepared. Buttercream, cream cheese frosting, and royal icing are typically very amenable to storage and revival. However, icings with fresh fruits or other perishable ingredients may not store as well and should be used as soon as possible.
Furthermore, consider the storage method based on the type of icing. For instance, buttercream does very well in the refrigerator and can even be frozen. Royal icing also freezes well but needs proper rehydration after thawing. Icings containing high amounts of dairy products might exhibit changes in texture or flavor after freezing, so test a small batch first.
How long can leftover icing be safely stored?
The storage duration depends heavily on the type of icing and the storage method employed. Buttercream and cream cheese frosting, when properly stored in an airtight container in the refrigerator, are typically good for up to a week. Freezing can extend this period to several months, often up to 2-3 months without significant quality degradation.
Royal icing, due to its high sugar content, has a longer shelf life. Refrigerated royal icing can last up to two weeks, while frozen royal icing can be stored for up to three months. However, it’s always essential to use your senses; if the icing develops an unusual odor, appearance, or texture, it should be discarded regardless of the storage time.
What is the best way to store leftover buttercream icing?
The optimal method for storing leftover buttercream is in an airtight container, preferably a plastic container or a glass jar with a tight-fitting lid. This prevents the buttercream from drying out and absorbing odors from the refrigerator. It is best to fill the container as completely as possible to minimize air exposure which can lead to oxidation.
Before sealing the container, press a piece of plastic wrap directly onto the surface of the buttercream. This creates an additional barrier against air and helps to prevent a skin from forming on the surface. Refrigerate the buttercream immediately after it has cooled down completely.
Can I freeze leftover icing, and how do I do it correctly?
Yes, freezing leftover icing is an excellent way to extend its shelf life, especially for buttercream and royal icing. To freeze it correctly, first, ensure the icing is completely cool. Then, transfer it to a freezer-safe airtight container. Consider using a freezer bag and squeezing out any excess air to minimize freezer burn.
For best results, divide the icing into smaller portions before freezing, making it easier to thaw only what you need. Label the container with the date and type of icing. When ready to use, thaw the icing in the refrigerator overnight for best results. Avoid thawing at room temperature, as this can promote bacterial growth.
How do I revive icing that has become too thick after storage?
Icing that has thickened after refrigeration or freezing often needs to be revived to its original consistency. The simplest method for buttercream or cream cheese frosting is to add a small amount of liquid, such as milk or cream, one teaspoon at a time, and then gently beat the icing until it reaches the desired consistency. Avoid adding too much liquid at once, as this can make the icing too thin.
For royal icing, add a few drops of water at a time and stir well. Be careful not to overwater royal icing as it can become too runny. You can also try gently warming the icing in the microwave for a few seconds, but be cautious not to melt it. After adding the liquid or warming it slightly, always beat or stir the icing thoroughly to ensure even distribution.
What if my icing has separated after being stored?
Separation is a common occurrence, especially with buttercream frosting after refrigeration. This is usually due to the fat solidifying and separating from the liquid. Don’t worry, this is typically easily remedied. Simply allow the icing to come to room temperature for a short period, enough to soften but not melt.
Once slightly softened, use an electric mixer to beat the icing vigorously until it becomes smooth and creamy again. The mixing process will re-emulsify the fat and liquid, restoring the icing to its original consistency. If the icing remains stubbornly separated, you can try adding a very small amount of powdered sugar to help bind the ingredients back together, but add it sparingly to avoid making the icing too sweet or stiff.
How can I tell if leftover icing has gone bad and should be discarded?
The best way to determine if leftover icing has gone bad is to rely on your senses. First, visually inspect the icing for any signs of mold growth or unusual discoloration. If you see anything that looks suspicious, discard the icing immediately. Mold can grow in refrigerated conditions, even in sugary environments.
Next, smell the icing. If it has developed a sour, rancid, or otherwise unpleasant odor, it has likely spoiled. Finally, if the icing looks and smells okay, check the texture. If the texture is drastically different from when it was originally made – such as being overly watery, excessively dry, or containing large, hard crystals – it’s best to err on the side of caution and discard it.
