As a baker, there’s nothing more frustrating than spending hours perfecting a cake, only to have the icing melt and ruin the entire presentation. It’s a common problem that many bakers face, but what causes icing to melt, and more importantly, how can you prevent it? In this article, we’ll delve into the world of icing and explore the reasons behind its melting, as well as provide you with some valuable tips and tricks to keep your icing stable and looking great.
Understanding Icing and its Melting Point
Before we dive into the reasons behind icing melting, it’s essential to understand the basics of icing and its melting point. Icing, also known as frosting, is a sweet glaze made from sugar, fat (such as butter or cream), and sometimes milk or cream. The type of icing you use can affect its melting point, but generally, icing is sensitive to temperature and humidity.
The melting point of icing depends on the type of sugar used, the ratio of sugar to fat, and the temperature of the environment. Generally, icing starts to melt at temperatures above 75°F (24°C). However, this can vary depending on the specific ingredients and conditions.
The Role of Sugar in Icing Melting
Sugar plays a crucial role in icing melting. Granulated sugar, which is commonly used in icing, has a high melting point of around 160°F (71°C). However, when sugar is mixed with fat and liquid, its melting point decreases. This is because the fat and liquid molecules disrupt the sugar crystals, making them more prone to melting.
There are different types of sugar, and each has a different melting point. Powdered sugar, for example, has a lower melting point than granulated sugar, which is why it’s often used in icings that require a smoother texture.
How Humidity Affects Icing Melting
Humidity is another critical factor that affects icing melting. High humidity can cause icing to melt faster, as the moisture in the air dissolves the sugar crystals and breaks down the fat molecules. This is why it’s essential to work in a cool, dry environment when making and decorating cakes.
Common Reasons Why Icing Melts
Now that we understand the basics of icing and its melting point, let’s explore some common reasons why icing melts:
- High temperatures: As mentioned earlier, icing starts to melt at temperatures above 75°F (24°C). If you’re working in a hot environment or transporting your cake to a warm location, the icing may melt.
- High humidity: High humidity can cause icing to melt faster, as the moisture in the air dissolves the sugar crystals and breaks down the fat molecules.
- Incorrect ratio of sugar to fat: If the ratio of sugar to fat is off, the icing may be more prone to melting. A general rule of thumb is to use a 1:1 ratio of sugar to fat.
- Using low-quality ingredients: Using low-quality ingredients, such as old or low-grade sugar, can affect the melting point of the icing.
- Overmixing: Overmixing the icing can cause the sugar crystals to break down, leading to a softer, more prone to melting icing.
How to Prevent Icing from Melting
Preventing icing from melting requires some planning and attention to detail. Here are some tips to help you keep your icing stable:
- Work in a cool, dry environment: Make sure your workspace is cool and dry, with a temperature between 60°F (15°C) and 70°F (21°C).
- Use a thermometer: Use a thermometer to check the temperature of your workspace and the icing.
- Use a high-quality icing: Use a high-quality icing that is specifically designed for decorating cakes.
- Don’t overmix: Mix the icing just until the ingredients come together. Overmixing can cause the sugar crystals to break down, leading to a softer, more prone to melting icing.
- Add a stabilizer: Adding a stabilizer, such as corn syrup or gelatin, can help prevent the icing from melting.
Stabilizers: What They Are and How They Work
Stabilizers are ingredients that help prevent icing from melting. They work by inhibiting the growth of sugar crystals, which can cause the icing to become grainy or melt.
Some common stabilizers used in icing include:
- Corn syrup: Corn syrup is a common stabilizer used in icing. It helps to inhibit the growth of sugar crystals and prevents the icing from becoming too thin.
- Gelatin: Gelatin is another common stabilizer used in icing. It helps to strengthen the icing and prevent it from melting.
Conclusion
Icing melting is a common problem that many bakers face, but by understanding the basics of icing and its melting point, you can take steps to prevent it. By working in a cool, dry environment, using a high-quality icing, and adding a stabilizer, you can keep your icing stable and looking great.
Remember, the key to preventing icing from melting is to control the temperature and humidity of your workspace. By doing so, you can create beautiful, professional-looking cakes that will impress your clients and customers.

What causes icing to melt on a cake?
Icing on a cake can melt due to various reasons, primarily related to temperature and humidity. When the cake is exposed to warm temperatures or high humidity, the icing can start to soften and melt. This is especially true for cakes with buttercream or cream cheese icing, as they are more sensitive to temperature changes.
In addition to temperature and humidity, other factors can contribute to melting icing. For example, if the cake is not stored properly or is transported in a warm vehicle, the icing can melt. Similarly, if the cake is displayed near a heat source, such as an oven or a sunny window, the icing can melt.
How can I prevent icing from melting on a cake?
To prevent icing from melting on a cake, it’s essential to store the cake in a cool, dry place. If you’re displaying the cake, make sure it’s away from direct sunlight and heat sources. You can also use a cake stand with a built-in cooling system or a turntable with a cooling pad to keep the cake at a stable temperature.
Another way to prevent icing from melting is to use a more stable type of icing, such as royal icing or fondant. These types of icing are less sensitive to temperature changes and can withstand warmer temperatures without melting. Additionally, you can add stabilizers, such as gelatin or corn syrup, to your icing to help prevent melting.
What type of icing is most resistant to melting?
Royal icing is generally the most resistant to melting, as it’s made with powdered sugar and egg whites or meringue powder. This type of icing is often used for decorating cakes and can withstand warmer temperatures without melting. Fondant is another type of icing that’s resistant to melting, as it’s made with sugar, corn syrup, and water.
However, it’s worth noting that even royal icing and fondant can melt if exposed to extremely high temperatures or humidity. To ensure that your icing remains stable, it’s still important to store the cake in a cool, dry place and avoid exposing it to direct sunlight or heat sources.
Can I use shortening to prevent icing from melting?
Yes, using shortening, such as Crisco, in your icing can help prevent it from melting. Shortening has a higher melting point than butter, so it can help keep the icing stable in warmer temperatures. However, keep in mind that using shortening can affect the flavor and texture of the icing.
When using shortening in your icing, make sure to use a high-quality shortening that’s designed for baking. Also, be aware that using too much shortening can make the icing taste greasy or artificial. It’s best to use a combination of butter and shortening to achieve the right balance of flavor and stability.
How can I fix melted icing on a cake?
If the icing on your cake has melted, there are a few ways to fix it. One way is to refrigerate the cake for about 10-15 minutes to firm up the icing. Then, use a spatula or offset spatula to smooth out the icing and remove any excess.
Another way to fix melted icing is to re-whip the icing and reapply it to the cake. This works best if the icing has only slightly melted and still has a stable consistency. If the icing has melted significantly, it may be best to start over with a new batch of icing.
Can I use a hair dryer to fix melted icing on a cake?
No, it’s not recommended to use a hair dryer to fix melted icing on a cake. While it may seem like a quick fix, using a hair dryer can actually make the problem worse. The heat from the hair dryer can melt the icing further, causing it to become uneven and difficult to work with.
Instead of using a hair dryer, it’s best to refrigerate the cake to firm up the icing, and then use a spatula or offset spatula to smooth out the icing. If the icing is severely melted, it may be best to start over with a new batch of icing.
How can I transport a cake with icing without it melting?
To transport a cake with icing without it melting, it’s essential to keep the cake cool and away from direct sunlight. You can use a cake box or a covered cake stand to protect the cake from the elements. If you’re transporting the cake in a vehicle, make sure to keep it away from direct sunlight and heat sources, such as the dashboard or rear window.
You can also use ice packs or cold gel packs to keep the cake cool during transport. Place the ice packs or cold gel packs in the cake box or near the cake to keep it at a stable temperature. This can help prevent the icing from melting during transport.
