Frosted cakes are a staple at many celebrations, from birthdays to weddings. However, when it comes to storing these delicious treats, many people are left wondering how long they can sit out unrefrigerated. In this article, we will delve into the world of frosted cakes and explore the factors that affect their shelf life, as well as provide guidance on how to store them safely.
Understanding the Components of Frosted Cake
Before we dive into the specifics of storing frosted cake, it’s essential to understand the components that make up this sweet treat. A typical frosted cake consists of:
- Cake: The base of the cake, which can be made from a variety of ingredients, including flour, sugar, eggs, and butter.
- Frosting: The sweet and creamy topping that covers the cake, typically made from butter, sugar, and sometimes milk or cream.
- Fillings: Some cakes may have fillings, such as jam or buttercream, which can affect the overall shelf life of the cake.
The Role of Frosting in Cake Shelf Life
Frosting plays a significant role in determining the shelf life of a frosted cake. The type of frosting used can greatly impact how long the cake can sit out unrefrigerated. There are two main types of frosting:
- Buttercream frosting: Made from butter, sugar, and sometimes milk or cream, buttercream frosting is a popular choice for cakes. However, it is more prone to spoilage than other types of frosting.
- Cream cheese frosting: Made from cream cheese, butter, and sugar, cream cheese frosting is a tangy and creamy alternative to buttercream. It is generally more stable than buttercream frosting and can be left out for longer periods.
Factors Affecting Cake Shelf Life
Several factors can affect the shelf life of a frosted cake, including:
- Temperature: Cakes should be stored in a cool, dry place, away from direct sunlight and heat sources.
- Humidity: High humidity can cause the cake to become soggy and the frosting to melt.

How long can a frosted cake sit out unrefrigerated without spoiling?
A frosted cake can typically sit out unrefrigerated for several hours, depending on the type of frosting and the ambient temperature. If the cake is frosted with a non-dairy frosting, such as royal icing or powdered sugar, it can usually be left out for 2-3 days without refrigeration. However, if the cake is frosted with a dairy-based frosting, such as buttercream or cream cheese, it’s best to refrigerate it within 2 hours to prevent spoilage.
It’s also important to consider the temperature and humidity of the environment where the cake is sitting. If the temperature is above 70°F (21°C) or the humidity is high, it’s best to refrigerate the cake as soon as possible to prevent bacterial growth and spoilage. In general, it’s always better to err on the side of caution and refrigerate the cake if you’re unsure how long it’s been out.
What factors affect the shelf life of a frosted cake left unrefrigerated?
Several factors can affect the shelf life of a frosted cake left unrefrigerated, including the type of frosting, the temperature and humidity of the environment, and the handling and storage of the cake.

You should also label the container with the date and contents, so you can easily keep track of how long the cake has been frozen. When you’re ready to serve the cake, simply thaw it in the refrigerator or at room temperature.
What are the signs of spoilage in a frosted cake?
There are several signs of spoilage to look out for in a frosted cake, including an off smell, slimy texture, or mold growth. If the cake has an unpleasant odor or taste, it’s likely spoiled and should be discarded. You should also check the cake for any visible signs of mold or bacterial growth, such as green or black spots.
In addition to these visible signs, you should also check the cake’s texture and consistency. If the cake is soggy or has an unusual texture, it may be spoiled. Finally, if you notice any unusual colors or patterns on the cake, it’s best to err on the side of caution and discard it. Remember, it’s always better to be safe than sorry when it comes to food safety.
Can I still serve a frosted cake that’s been left out for too long?
No, it’s not recommended to serve a frosted cake that’s been left out for too long. If the cake has been left out for an extended period, it may have spoiled or developed off-flavors. Serving a spoiled cake can be a food safety risk, and it’s not worth the risk of making your guests sick.
Instead, it’s best to err on the side of caution and discard the cake. If you’re unsure whether the cake is still safe to eat, it’s better to be safe than sorry and discard it. You can always bake a new cake or order one from a bakery if you need a replacement. Remember, food safety should always be your top priority when serving food to others.
