The allure of a beautifully decorated cake, adorned with smooth, glossy ganache, is undeniable. But what if your cake already boasts a layer of frosting? Can you simply slather ganache over it and expect delectable results? The answer, as with most things in baking, isn’t a straightforward yes or no. It depends on several factors, from the type of frosting you’re using to the consistency of your ganache. This comprehensive guide will delve into the nuances of pairing ganache with frosting, ensuring your cake decorating endeavors are a resounding success.
Understanding Ganache and Frosting Dynamics
Before we dive into the specifics, let’s establish a clear understanding of what ganache and frosting are, and how their properties influence their compatibility.
What is Ganache?
Ganache, at its core, is a simple mixture of chocolate and cream. The ratio of chocolate to cream dictates its consistency, ranging from a pourable glaze to a firm truffle filling. The higher the chocolate content, the firmer the ganache will be. This versatility makes ganache a popular choice for everything from glazing cakes and cupcakes to creating intricate chocolate decorations.
The type of chocolate used significantly impacts the final flavor and texture of the ganache. Dark chocolate creates a rich, intense flavor, while milk chocolate results in a sweeter, milder ganache. White chocolate, being less intense, often requires careful balancing with other flavors.
Exploring the World of Frosting
Frosting, unlike ganache’s simple composition, encompasses a wide variety of sweet coverings. Each type possesses distinct characteristics that influence its suitability as a base for ganache.
Buttercream, a classic choice, is made with butter and sugar, often with the addition of eggs or meringue. It’s known for its smooth texture and ability to hold its shape, making it ideal for piping intricate designs.
Cream cheese frosting, as the name suggests, incorporates cream cheese, giving it a tangy flavor and a slightly softer texture than buttercream.
Whipped cream frosting, light and airy, is made by whipping heavy cream with sugar and sometimes stabilizers. It’s delicate and prone to melting, making it less stable than other frosting options.
Royal icing, a hard-drying icing made with powdered sugar and egg whites (or meringue powder), is primarily used for decorating cookies and gingerbread houses, but can also be used for creating detailed decorations on cakes.
The Compatibility Question: Can Ganache and Frosting Coexist?
Now, let’s address the central question: can you put ganache over frosting? The answer is a qualified yes. It is possible, but certain conditions must be met to ensure a successful outcome. The key lies in understanding the interaction between the ganache and the frosting and choosing appropriate pairings.
Factors Influencing Ganache-Frosting Compatibility
Several factors come into play when determining whether ganache can be successfully applied over frosting:
- Frosting Type: Some frostings, like stable buttercream, provide a solid base for ganache. Others, like whipped cream frosting, are too delicate and will likely melt or collapse under the weight of the ganache.
- Ganache Consistency: The consistency of the ganache is crucial. A very liquid ganache may soak into the frosting, creating a soggy mess. A very firm ganache may be difficult to spread smoothly.
- Temperature: Both the ganache and the frosting’s temperature impact their interaction. Applying warm ganache to cold frosting can cause the frosting to melt.
- Cake Stability: The overall stability of the cake is also important. A wobbly or unstable cake is more likely to collapse under the weight of the ganache, especially if it already has a thick layer of frosting.
Ideal Frosting Choices for Ganache Application
The following frostings are generally considered good choices for layering with ganache:
- American Buttercream: This is a relatively stable frosting that provides a good base for ganache. Its high sugar content helps to create a barrier between the cake and the ganache, preventing the ganache from soaking in too much.
- Swiss Meringue Buttercream: Known for its silky smooth texture and less sweet flavor, Swiss meringue buttercream is another excellent choice. It’s more stable than American buttercream and can support the weight of ganache without melting or becoming overly soft.
- Italian Meringue Buttercream: Similar to Swiss meringue buttercream, Italian meringue buttercream is also very stable and can withstand the weight of ganache. It has a slightly richer flavor than Swiss meringue buttercream.
- Cream Cheese Frosting (with caution): While cream cheese frosting is delicious, it’s softer than buttercream. If using cream cheese frosting, ensure it’s firm and well-chilled before applying the ganache. Consider adding a stabilizer like cornstarch to improve its firmness.
Frostings to Avoid When Using Ganache
Certain frostings are not well-suited for layering with ganache due to their instability or high moisture content:
- Whipped Cream Frosting: This frosting is too delicate and will melt or collapse under the weight of ganache.
- Seven-Minute Frosting: This frosting is similar to whipped cream frosting in its delicate nature and is not recommended for use with ganache.
- Any very thin or runny frosting: Frostings that are excessively thin or runny will not provide a stable base for ganache and may result in a messy and unstable cake.
The Art of Applying Ganache Over Frosting: A Step-by-Step Guide
Assuming you’ve chosen a compatible frosting and ganache combination, here’s a step-by-step guide to applying ganache over frosting:
- Prepare the Cake: Ensure your cake layers are level and properly chilled. This will provide a stable foundation for the frosting and ganache.
- Frost the Cake: Apply a thin, even layer of your chosen frosting to the cake. This is often referred to as a “crumb coat.” Chill the frosted cake for at least 30 minutes to allow the frosting to set.
- Prepare the Ganache: Make your ganache according to your desired recipe. Allow it to cool slightly until it reaches a consistency that is pourable but not too runny. The ideal consistency should be similar to that of warm honey.
- Test the Ganache: Before pouring the ganache over the entire cake, test a small amount on a hidden area of the frosting. This will allow you to assess the ganache’s consistency and ensure it’s not melting the frosting.
- Pour the Ganache: Carefully pour the ganache over the center of the cake, allowing it to flow down the sides. Use a spatula or offset spatula to gently guide the ganache, ensuring it covers the entire surface evenly.
- Smooth the Ganache: Once the cake is coated, use a clean, warm spatula to smooth the ganache and remove any imperfections. Work quickly and efficiently to prevent the ganache from setting too quickly.
- Chill the Cake: Refrigerate the cake for at least 30 minutes to allow the ganache to set completely.
- Decorate (Optional): Once the ganache has set, you can further decorate the cake with sprinkles, chocolate shavings, or other desired embellishments.
Tips for Success: Mastering the Ganache-Frosting Combination
To ensure a flawless ganache-over-frosting application, consider these additional tips:
- Use a turntable: A turntable makes it much easier to evenly coat the cake with ganache and smooth the surface.
- Warm your spatula: Dipping your spatula in warm water and drying it before smoothing the ganache will help to create a smooth, glossy finish.
- Work in a cool environment: A cool environment will help to prevent the frosting and ganache from melting too quickly.
- Don’t overwork the ganache: Overworking the ganache can cause it to become grainy or dull.
- Consider a dam of frosting: If your ganache is on the thinner side, consider creating a dam of thicker frosting around the edge of the cake to prevent it from running off.
- Practice makes perfect: Don’t be discouraged if your first attempt isn’t perfect. Practice makes perfect, and with a little experimentation, you’ll master the art of layering ganache over frosting.
- Match flavors: Complementary flavors enhance the overall experience. Pair dark chocolate ganache with a vanilla buttercream, or white chocolate ganache with a raspberry cream cheese frosting.
Troubleshooting Common Issues
Even with careful planning, you may encounter some common issues when applying ganache over frosting. Here’s how to troubleshoot them:
- Ganache is too runny: If your ganache is too runny, add more melted chocolate to thicken it.
- Ganache is too thick: If your ganache is too thick, add a small amount of warm cream to thin it.
- Frosting is melting: If your frosting is melting, ensure it’s well-chilled and work quickly. You can also try using a more stable frosting.
- Ganache is not smooth: If your ganache is not smooth, try using a warmer spatula and working in a cool environment.
- Ganache is cracking: If your ganache is cracking, it may be too cold or too thick. Allow it to come to room temperature slightly before smoothing.

Can I put ganache directly over any type of frosting?
While ganache can be paired with many frostings, the best results are generally achieved with stable frostings like American buttercream or a firm cream cheese frosting. These frostings offer a solid base that won’t easily melt or become overly soft under the weight and warmth of the ganache. A stable base is crucial to prevent the ganache from causing the frosting underneath to bulge, sag, or even separate from the cake.
Avoid layering ganache directly over very delicate or unstable frostings like whipped cream frosting or some meringue-based frostings. These frostings lack the structural integrity to support the ganache and can lead to a messy and unattractive presentation. If you choose to use a more delicate frosting, consider chilling the frosted cake thoroughly before applying a thin, cooled layer of ganache. This can help minimize the risk of melting or destabilizing the frosting underneath.
What consistency of ganache is best for going over frosting?
The ideal ganache consistency for layering over frosting is pourable, but not so thin that it runs uncontrollably. You want a ganache that is thick enough to hold its shape slightly but flows smoothly over the frosting, creating an even and appealing finish. A good test is to lift a spoonful of ganache; it should slowly drizzle back into the bowl and maintain a slight peak before melting back in.
If your ganache is too thick, it will be difficult to spread evenly and can pull or tear the frosting underneath. If it’s too thin, it will run off the cake, creating a mess and failing to provide adequate coverage. Adjust the consistency by adding small amounts of cream to thin it or chocolate to thicken it, testing until you reach the desired pourable texture before applying it to your frosted cake.
How long should I chill the frosted cake before adding ganache?
Chilling the frosted cake is a crucial step before applying ganache, especially with softer frostings. A well-chilled cake provides a firm and stable surface, preventing the ganache from melting the frosting and ensuring a clean, even application. Generally, chilling the cake for at least 30 minutes to an hour in the refrigerator is recommended before proceeding.
For especially delicate frostings or in warmer environments, consider chilling the cake for an even longer period, up to two hours. The goal is to solidify the frosting enough to create a barrier between it and the warmer ganache. A thoroughly chilled cake will also help the ganache set more quickly and evenly, resulting in a smoother and more professional-looking finish.
What type of chocolate is best for ganache used over frosting?
The type of chocolate you use significantly impacts the flavor and texture of your ganache. High-quality chocolate, whether dark, milk, or white, will generally yield the best results. Dark chocolate, with its intense flavor and lower sugar content, provides a rich and balanced ganache that complements many frostings. Milk chocolate offers a sweeter and creamier option, while white chocolate is ideal for creating a lighter, more delicate flavor profile.
When selecting chocolate, opt for couverture chocolate, which contains a higher percentage of cocoa butter. This will result in a smoother, shinier, and more luxurious ganache. Avoid using chocolate chips, as they often contain stabilizers that can prevent them from melting as smoothly. Consider experimenting with different chocolates to find the flavor profile that best complements your frosting and overall cake design.
Can I add flavoring to the ganache before putting it over frosting?
Yes, adding flavorings to ganache is an excellent way to customize the taste and complement the frosting and cake flavors. Extracts like vanilla, almond, or peppermint can be easily incorporated into the ganache. For more intense flavors, consider using liqueurs or coffee. Be mindful of the liquid content of any flavoring additions, as excessive liquid can affect the ganache’s consistency.
You can also infuse the cream used to make the ganache with flavors by steeping spices, herbs, or citrus zest in it before heating. This allows the flavor to subtly permeate the ganache. Add flavorings gradually and taste as you go to ensure the ganache doesn’t become overpowering or lose its desired consistency. Properly flavored ganache can significantly enhance the overall taste and appeal of your cake.
How can I prevent the ganache from dripping too much down the sides of the cake?
Controlling the drip of ganache is key to achieving a professional-looking finish. Start by ensuring the ganache is at the correct pourable consistency; it shouldn’t be too thin. When pouring the ganache over the cake, begin in the center and gently guide it towards the edges, allowing it to naturally flow down the sides. Avoid pouring too much ganache at once, as this can increase the likelihood of excessive dripping.
If you prefer a cleaner, more controlled drip, use a spoon or piping bag to create individual drips along the edge of the cake. This allows you to dictate the length and placement of each drip. You can also chill the cake after applying the ganache for a short period to help the drips set slightly before they become too long. Practice makes perfect, so don’t be afraid to experiment with different techniques to find what works best for you.
What should I do if the ganache doesn’t set properly after being applied?
If your ganache fails to set properly, several factors could be the cause. The most common reason is an incorrect chocolate-to-cream ratio, resulting in too much liquid in the ganache. If this is the case, gently melt a small amount of additional chocolate and mix it into the ganache. This will help to thicken the mixture and promote setting. Also, ensure that the cake is adequately chilled.
Another reason for incomplete setting could be the ambient temperature being too warm. If this is the case, place the cake in the refrigerator for a longer period, allowing the ganache to firm up at a cooler temperature. Avoid placing the cake in the freezer, as this can alter the texture of both the ganache and the frosting. In most cases, adjusting the chocolate-to-cream ratio or lowering the temperature will resolve the issue and allow the ganache to set properly.
