Cake Decorators Chocolate Ganache
The perfect chocolate ganache for decorating a cake is one that you can use to cover a cake with fondant. And, I call it the cake decorators chocolate ganache. One that adds stability to sculpted novelty cake and stays firm when stacked into a tiered wedding cake. In fact, my chocolate ganache is like my rock for me as a cake decorator.
When I started decorating cake, one of my first failures as a cake decorator was my ganache. I made a delicious ganache, it looked so delicious. But, when I covered it with fondant it was a big mess. The ganache was soft. So, covering the cake with fondant was an absolute nightmare
And, I wondered, how do they do it? How do these successful cake decorators have ganache cakes that don’t look like it’s melting? When they cover the cake, they are not struggling like me. Well, it took me a few times to realize that I was using the regular classic chocolate ganache recipe.
So, today, I want to share with you the ganache recipe used by cake decorators. This is the ganache you use under fondant, or when working with a novelty or sculpted cake. And, this is also the ganache you use when you want to get sharp edges on your cakes.
Ingredients and substitutes
- Chocolate – Ganache can be made with any chocolate, coverture, or compound. And, the quality of chocolate you use will determine how delicious your ganache will taste. I use Callebaut or Laubeca. In fact, most of my ganache cakes have 70% cocoa dark chocolate. And, the reason I like to use dark is because I usually fill my cakes with buttercream. So, the dark chocolate cuts down some of the sweetness. Having said that, you can use any percentage of chocolate from 55% to 90%.
White chocolate – Works differently from dark, semi-sweet, or milk chocolate. Hence, I will cover that in another post here. And, I will explain in detail with a video of how I make my classic white chocolate ganache as well as cake decorators white chocolate ganache. - Cream – The high the percentage of fat in the cream the creamier and richer the ganache. In addition, in some cases, it will bring out the sweetness in the chocolate as well. In fact, I usually use no less than 38% fat. Since, I think it always has the best consistency for the ganache. Having said that, you can use anything from 32% to 45%.
And, if you are unable to use fresh whipping cream, you can also use coconut cream and follow the same exact process we do below.
Ganache for fondant cakes
- Stovetop method – Place chocolate in a heatproof bowl and set aside. Heat the heavy cream in a saucepan over medium heat until it begins to simmer. Pour the cream over the chocolate and let it sit for 5 minutes. Then, stir with a spatula until smooth.
Pro tip – DO NOT let the cream come to a rapid boil as it can burn the chocolate). If the chocolate is chopped fine there should be no more chocolate pieces. If necessary, melt in the microwave for 20 to 30 seconds. - Microwave Method – Place the chopped chocolate into a microwave-safe bowl. Pour the cream all over the chocolate. Heat it in the microwave on high for a minute. Stir and continue to heat at 30-second intervals until you have a smooth ganache.
- Cover -Once the ganache is ready, cover it with plastic making sure the plastic touches the top surface of the ganache to prevent skin from forming on the top.
- Rest – Leave the ganache to set in the bowl at room temperature for a few hours or in the fridge for 2 hours. Once it reaches a spreading consistency it can be used for frosting.
- Storage – Ganache will keep at room temperature for 2 days. It can be kept in the refrigerator for up to 5 days. It can also be frozen for up to a month in the freezer. Thaw in the fridge overnight for best results.
Pro tip – To warm the ganache simply place it in the microwave for no more than 10 to 20 seconds intervals.
- Stack – Place the next layer on top followed by more frosting until you have stacked all four layers
Pro tip – Trim the outside edge if necessary – you can see me do this in my video – This ensures the sides are straight. - Level – Use a cake leveler to ensure the cake is leveled. You may need to press down on the side that is higher to help shimmy the frosting around.
Pro tip – Then use two bench scrapers on either side of the cake to ensure the sides are straight. (just so the layers are not peaking out)
- Chill – Place the cake in the fridge for 10 minutes – the frosting will set and the layers won’t move when you are frosting the outside.
- Cake top – Place a big dollop of ganache on the top layer. Spread it evenly making sure you have ganache over the edges.
- Cake board – Place a cake board the same size as the bottom board. Use two cake scrapers to make sure the top and bottom boards are aligned together. Chill the cake for 20 minutes.
- Cake sides – Using a spatula frost the sides of the cake with ganache. Make sure to use a paddle motion with the ganache – this prevents air pockets. Use a bench scraper to smooth the sides of the cake.
- Chill – Continue to spread and smooth the ganache until you have smooth sides. Chill the cake for at least 2 hours
- Top board – Use a hot spatula or knife. Place the spatula between the top cake board and the ganache (see video) Pass the spatula under the board until you have loosened the board from the cake.
Pro tip – dip the spatula in hot water. Gentle move the spatula – letting the heat from the spatula guide you along. Do not push too hard as the ganache will crack - Smooth top – The top will be uneven and rough – this is normal. Add just enough ganache to fill and cover the top. Use an offset spatula to smooth the top and use a bench scraper to smooth the sides.
Pro tip – Since the cake is chilled well the sides will remain smooth. - Edge – Once smooth the little ganache that’s left over the edges can be taken off with a spatula or knife (see video)
How much ganache do I need for my cake?
This is the amount of ganache I would use for my cakes when I was a professional cake decorator. It will give you a smooth firm canvas to cover with fondant. Having said that, you can use less or more as desired. For example, for our family we like less frosting so often I will use a filling in between layers and a thinner coat of ganache on the outside

Tips for making perfect ganache
To make the perfect ganache, there are a few tips to keep in mind.
- First, use high-quality chocolate and heavy cream for the best results.
- Chop the chocolate finely and
- heat the cream until it just begins to simmer. Pour the cream over the chocolate and let it sit for a few minutes before stirring until smooth.
- For a richer ganache, use a higher percentage of chocolate or add a tablespoon of butter.
- If your ganache is too thick, add a splash of cream to thin it out. Conversely, if it’s too thin, chill it in the fridge until it thickens up.
- Finally, be patient when working with ganache. It takes time to set properly, so allow enough time for it to cool and firm up before using it in your recipes.
Often, over-heated chocolate causes grainy chocolate ganache. Because, when you over-heat chocolate the fat in the chocolate separates or splits from the cocoa butter causing an oily, split, or grainy ganache.
Sometimes, yes. Depending on how hot the cream is. And, if the temperature of the cream is right it will help stabilize the fat in the chocolate and bring it all together. However, if it’s too hot it will make things worse. Whipping cream is fat too!
There are a few method to fix ganache.
I find using a blender to mix the ganache works best. The emulsification process combines the fat in the chocolate with the fat in the cream.
In addition, they say add corn syrup to a small batch of the ganache first, and mix it well. Then, add that to the rest. However, I have not had much luck with this one.
Low-fat Milk – heat a little low-fat milk and add it a tablespoon at a time. The whey in the milk helps stabilize the fat in the ganache.
This happens when all the chocolate was not melted properly. So, all you have to do is melt the ganache in the microwave or double boiler. Then, stir constantly but until the ganache has just melted. Now, use a blender to break those small pieces of chocolate. Then, cool again until set to the right consistency before using.
The white lines are possibly fat from the chocolate that was separated. Hence, what you have is probably a split ganache.
However, it can still be used. Simply melt the ganache for 10 seconds, then mix throughly until you have a smooth ganache.
Again, use that 10-second burst in the microwave or few seconds on the double boiler.
Chill it for a few minutes in the fridge until the chocolate sets again. And, make sure to stir so it sets evenly.
If ever you do over-whip your ganache, just add 1 or 2 tbsp of warm cream or milk and mix thoroughly with the back of your spoon. You may deflate some of the volumes but that’s what you want. And, it will be smooth and creamy again.
Ganache sets at room temperature after a few hours. And, depending on the weather, it can take from 4 to 8 hours. Also, you can set ganache in the fridge for a shorter time. And, when taken out of the fridge there will be some condensation but that usually will disappear as the ganache sets again.
In terms of taste it’s individual preference. Some love buttercream while others love chocolate. In addition, the chocolate sets better than butter in most weather conditions. Therefore, it’s ideal for working under fondant. That is why ganache has become the most preferred frosting amongst cake decorators.
By whipping it! When whipped, the cream in the ganache becomes thicker making a thicker ganache. And, it also lightens the ganache both in color and texture. Also, a thicker ganache works best in between layers as it spread evenly and holds its shape.
Though ganache contains cream, this cake decorators ganache can stay at room temperature for up to 4 days. And, you can also keep it in the fridge for up to a month. Then, thaw at room temperature overnight or a few hours.
It is best to thaw ganache at room temperature for a few hours. And yet, if you must, it is also possible to reheat it. My preferred method is the microwave at 10 seconds burst. And, make sure to stir between each burst. Since, when it comes to chocolate 10 seconds is more than enough.
And, you can also use a double boiler making sure to keep a constant eye on the ganache and stirring as needed.

Consistency for covering a cake
- Ganache rested may not necessarily be ideal to just start using.
- The ideal consistency is peanut butter consistency.
- You want to be able to hold the ganache on the spatula and spread it around the cake.
- The best way to bring it to consistency
- In cold weather – stick it in the microwave for 10 secs (when it comes to chocolate 10 secs is a lot so don’t’ over-heat)
- If the ganache was in the fridge resting it out for an hour works too.
- If you live in a hot and humid climate – just a vigorous stir with a spatula is all you need.
- Always chop chocolate finely or keep them in similar size pieces. That way the whole batch will melt evenly.
- Never let heavy whipping cream boil. You want the cream to be hot but not boiling. If necessary it’s better to place the ganache in the microwave for 30 seconds to get the last bit of unmelted chocolate.
- If you have one or two stubborn pieces of chocolate left in the ganache that won’t melt. It’s best to remove them, then to take a chance of overheating the whole batch and risking a split.
- Microwave ganache – often a culprit of overheated ganache. Depending on how big the batch is, start with 30 seconds then heat at increments of 1o secs stirring between every interval to distribute the heat evenly.
- Ganache has split or separated – this happens when the cocoa solids and fat don’t emulsify properly. Add a splash of milk and give it a good stir. Add another splash and stir again until you have a smooth ganache.
- If the chocolate looks lumpy, grainy means you have overheated the chocolate. Use a stick blender and give it a whiz. All should be well again.
- If you realize the ganache is split only after it has cooled. Add a little more chocolate to it. And reheat the melting process keeping a close watch, making sure to stir and encourage even distribution of heat. If necessary add more cream to maintain the ganache ratio you need.
- Never over mix chocolate ganache – this will incorporate too much air into the ganache but also can cause the ganache to split. Especially with white chocolate ganache keep stirring to a minimum once the chocolate is melted.
- Ganache is best made in a glass bowl when using a microwave and in stainless steel when using a stovetop. Never use plastic or aluminum for melting chocolate, the ganache will not have a shiny appearance.
- Place a plastic wrap/cling wrap directly over the ganache when letting it cool. This will prevent any crust from forming on top.
