When it comes to baking and decorating cakes, cupcakes, and cookies, icing is a star player that can transform simple treats into something truly spectacular. While many bakers know that certain icings require refrigeration to maintain their flavor and texture, others are perfectly fine sitting out at room temperature. This article delves into the types of icing that do not require refrigeration, offering insight into their composition, uses, and how to store them effectively.
The Basics of Icing and Refrigeration
Before we discuss which icings can be kept at room temperature, it’s vital to understand what icing is made of. Icing, also known as frosting, is typically a sweet, creamy topping used on baked goods. The primary ingredients in most icing recipes include sugar, fat (butter, cream cheese, or shortening), and flavoring (vanilla extract, cocoa powder, etc.).
Why Refrigeration Matters:
Refrigeration is essential for certain icings to prevent spoilage and maintain freshness. For example, icings made with dairy or egg products tend to be more perishable and should be stored in the fridge to deter bacteria growth and maintain their consistency. However, other icings are more resilient and can withstand being left out at room temperature.
Types of Icing That Don’t Need Refrigeration
Let’s explore some of the most popular types of icing that are safe to keep at room temperature, making them convenient options for both home bakers and professional pastry chefs.
1. Buttercream Icing
Buttercream icing is one of the most popular and versatile icings used in cake decorating. It comes in various forms, including American, Swiss, and Italian buttercream.
- American Buttercream: This version is made with butter, powdered sugar, vanilla extract, and milk or cream. It is rich and sweet, and it can sit at room temperature for up to two days, making it highly practical for events or parties.
- Swiss and Italian Meringue Buttercream: Also made with butter and sugar, these types incorporate egg whites which are cooked to form a meringue. When properly prepared and stored, these buttercreams can last at room temperature for a few days, offering a luxurious texture without requiring refrigeration.
2. Royal Icing
Royal icing is a hard-setting icing composed mainly of powdered sugar, egg whites (or meringue powder), and water. It is commonly used for decorating cookies, cakes, and gingerbread houses.
Room Temperature Stability: Since royal icing contains high sugar content, it dries quickly and hardens to create a firm exterior that prevents bacterial growth. It can be safely left out at room temperature for weeks in its hardened state, making it perfect for cookie decorating projects where you want the designs to hold their shape and freshness.
3. Glaze Icing
Glaze icing, often used for donuts and pastries, is a simple mixture of powdered sugar and liquid (like milk, lemon juice, or water).
Longevity at Room Temperature: This icing does not typically use dairy, making it safe to store at room temperature for up to two days before it begins to lose its sheen and flavor. Glaze icing hardens as it sets, allowing baked goods to remain fresh without the need for refrigeration.
4. Fondant
Fondant is a smooth and pliable icing made from sugar, water, and gelatin, often used for covering cakes and creating decorative elements.
Storage Guidelines: Fondant can be stored at room temperature for weeks. While it does not require refrigeration, it’s essential to keep it in an airtight container away from excessive heat or direct sunlight. Maintaining its pliability ensures successful application and shaping.
5. Cream Cheese Icing (Short Shelf Life)
While cream cheese icing is often considered a perishable icing due to its dairy content, it can be safe to use without refrigeration for a short period.
Usage Consideration: If you’re serving items decorated with cream cheese icing at room temperature, it’s best to use them within two hours to ensure safety, especially in warm weather. This icing is best kept chilled until you’re ready to serve.
When to Consider Refrigeration for Icing
While many icings can sit at room temperature, you should be mindful of certain key factors that could necessitate refrigeration.
1. Ingredients Matter
Look closely at the ingredients. Any icing containing perishable items, like cream cheese, whipped cream, or fresh fruit, should be refrigerated to avoid spoilage.
2. Weather Conditions
High temperatures and humidity can also affect the state of your icing. In warm conditions, it’s wise to err on the side of caution and refrigerate icings that may become unstable or melt.
The Final Touch: Storage Tips
To maximize the freshness and integrity of your icing, follow these essential storage tips:
- Use Airtight Containers: Store icings in tightly sealed containers to prevent drying out and to maintain optimal texture and flavor.
- Keep Away from Heat Sources: Place containers in cool, dry locations away from sunlight and heat to prolong their shelf life.

What are the different types of icing that do not require refrigeration?
Icing types that typically do not require refrigeration include royal icing, buttercream frosting, ganache, and fondant. Royal icing is primarily made from egg whites and powdered sugar, which dries hard and can be stored at room temperature. Buttercream frosting made with shortening instead of butter can also be kept out because it contains no perishable ingredients.
Additionally, ganache made with a higher ratio of chocolate to cream can be stable at room temperature. Fondant, which is primarily sugar-based, will remain intact when stored in a cool, dry place. While these frostings are shelf-stable, it’s essential to store them properly to maintain their textures and flavors.
How long can icing be stored at room temperature?
Most types of icing that don’t require refrigeration can be stored at room temperature for a few days up to two weeks. Factors such as the ingredients used, humidity, and temperature can influence how long they last. For instance, royal icing can typically last up to two weeks when kept in an airtight container, while buttercream can last about a week without being exposed to heat or moisture.
It’s vital to check the icing for any signs of spoilage, such as off smells, changes in consistency, or mold. If any of these signs are present, it’s best to discard the icing. Proper storage practices, like using airtight containers and keeping the icing in a cool place, can significantly extend its shelf life.
Can I use butter-based icing without refrigeration?
Yes, butter-based icing can be used without refrigeration, but it’s essential to consider how it’s made. If the buttercream is made with a significant amount of powdered sugar and used as a standard buttercream frosting, it can generally be kept at room temperature for a few days. The high sugar content helps to preserve it and keep it from spoiling.
However, if the buttercream contains additional dairy products, such as cream or milk, or if it’s made with softened butter that hasn’t been stabilized by adding shortening, refrigeration is recommended. To maintain its quality and flavor, always store the icing in an airtight container and use a cool, dry area.
What should I do if my icing starts to soften at room temperature?
If your icing begins to soften, you can often rectify the situation by refrigerating it briefly. For buttercream and icing made with cream, placing it in the fridge for a short time can help firm it back up. However, avoid leaving it too long in the refrigerator, as this can result in a texture that’s too firm for spreading or decorating.
Another approach is to gently mix in more powdered sugar to thicken the icing and restore its structure. If you’re working with royal icing that has softened, adding a bit more powdered sugar can help restore the correct consistency. Just be careful to add small amounts gradually to avoid making the icing too thick.
Is fondant safe to leave out of the fridge?
Yes, fondant is safe to leave out of the fridge because it is primarily comprised of sugar, which acts as a natural preservative. When stored in a cool, dry place away from direct sunlight, fondant can maintain its integrity and texture for several weeks. Proper storage is still crucial, as exposure to moisture can lead to sticky or unusable fondant.
To keep fondant fresh, wrap it tightly in plastic wrap and store it inside an airtight container. Doing so will prevent it from drying out or becoming hard. If used on a cake or cupcake, the fondant-covered items can also be stored at room temperature, as long as they are not exposed to humid conditions.
Can I use icing made with egg whites without refrigeration?
Icing made with egg whites, such as royal icing, can typically be left at room temperature for several days without refrigerator storage. This icing dries hard and forms a protective barrier that helps to preserve it. However, it’s essential to ensure that the egg whites are pasteurized to reduce the risk of foodborne illness, particularly if it will be served to vulnerable populations.
If royal icing has been exposed to moisture or humidity, it may need to be discarded, as the risk of spoilage increases. Always store any leftover icing in an airtight container to keep it fresh, and be cautious about the environmental conditions it will be kept in, as this icing can become soft and lose its structure if subjected to heat or dampness.
What impact does humidity have on icing storage?
Humidity can significantly impact icing storage and stability. High humidity can cause icing to become soft, sticky, or even melt, which may compromise both texture and appearance. For instance, buttercream and royal icing may lose their structure when exposed to excessive moisture in the air, leading to a less-than-desirable finish on baked goods.
To best store icing in humid conditions, it’s advisable to keep it in an air-tight container and in a cool environment. Some decorators may even recommend using dehumidifiers in their kitchens to create a stable atmosphere for cake decorating. Monitoring humidity levels and taking protective measures can help you maintain icing quality.
