How to make the best Chocolate Mousse
To make the best Chocolate Mousse you need just 5 ingredients – egg yolks, heavy cream, granulated sugar, semi-sweet chocolate, and powdered sugar.
First Step: Heat heavy cream, egg yolks, and sugar
In a heavy-bottomed pot, combine 3/4 cup of heavy cream, egg yolks, and granulated sugar and heat up over medium heat until the back of a spoon is coated about 1-2 minutes. Whisk continuously. Do not boil at any time and do not overcook or the chocolate ganache could split. Read on to know what to do if the ganache splits.
This is how it looks like after combining all ingredients:
This is how it looks like after 1-2 minutes:
Second Step: Add melted chocolate
Then remove the pot from the heat whisk 1-2 minutes. Then add the melted chocolate and whisk until combined.
Then transfer to a large mixing bowl and let cool to room temperature. Whisk occasionally.
Third Step: Mix heavy cream
In a large mixing bowl, using an electric mixer fitted with a whisk attachment, whip heavy cream on medium-high speed until soft peaks form.
Then add powdered sugar and whisk until stiff peaks form.
Fourth Step: Add whipped cream to the chocolate ganache
Remove 1/4 of the whipped cream and stir it with a whisk into the cooled chocolate ganache (should not be warm at all) until smooth and combined.
Then add the remaining whipped cream and carefully fold into the chocolate.
How to fold whipped cream into a chocolate mousse
Use a wooden spoon and start at one o’clock when working with the right hand and at eleven o’clock with the left hand.
Then scrape the spoon down the side of the bowl until you are at the bottom of the bowl and scrape along the side of the bowl towards you until you see the spoon again. The spoon should be at seven o’clock when folding with the right hand and at five o’clock with the left now.
Then fold over the top. Turn the bowl a little and repeat. Stop immediately when the chocolate mousse is incorporated.
This is how it looks like in the end:
I recommend to chill it in the fridge for at least 4-5 hours or overnight before serving. Don’t place it in the freezer to speed up the chilling process.
How to fix Chocolate Mousse
Why did my chocolate split?
If the chocolate splits, it gets grainy, and you have an oily film on the surface. This can happen if the chocolate was getting too fast too hot in the pan. So make sure that you remove the pan from the heat first, continue whisking for about 1 minute, and then whisk in the chocolate.
If this happened to you, the first thing you should do is to grab your electric mixer and mix until it comes together. In most cases, this will work fine and saves your ganache. It will be smooth and silky again. You can also mix in 1 tbsp of corn syrup or honey to smooth it.
If this didn’t help at all, heat up 1-2 tbsp of heavy cream and stir it into the ganache little by little. Stop adding heavy cream as soon as it comes together that it doesn’t get too liquid. Normally, this should help.
What is if your ganache is still broken? Well then you have to face the truth that the chocolate was way too hot, and you better do it again.
Why is my Chocolate Mousse runny?
There could be different reasons if your Chocolate Mousse turns out runny. First, the egg yolk mixture was not thick enough that it coats the back of a spoon. Second, the whipped cream was not stiff enough. Be careful with folding the whipped cream into the chocolate that you don’t destroy all the air pockets. Make also sure to use high-quality chocolate such as Lindt or Ghirardelli. And also, do not use low-fat heavy cream for Chocolate Mousse because it doesn’t hold its stand that long.
Why is my Chocolate Mousse hard?
Chocolate Mousse will firm up in the fridge to a scoopable texture. That is normal. The longer it stands at room temperature, the softer it gets again though. But if the Chocolate Mousse is hard and somewhat fudge-like rather than airy, then it can be that the chocolate or the whipped cream is the reason.
Please don’t use chocolate chips or low-quality chocolate for this recipe. The ratio of cocoa and fat in chocolate chips is different than in high-quality chocolate bars. Also, don’t use whipping cream with a higher fat content than 35%. More than that makes the Chocolate Mousse heavy and too fat.
I found a great resource on how to troubleshoot Chocolate Mousse. It explains what the possible reasons are if your Chocolate Mousse turns out grainy, thick, or runny and possible solutions for those problems.
How to serve Chocolate Mousse?
You could serve Chocolate Mousse right after making it if desired (will be very soft) or you chill it for a couple of hours it in the fridge before serving (recommended). I prefer Chocolate Mousse when it is chilled for at least 4-5 hours. You can also do it in advance and chill it overnight. It will be firm and scoopable straight out of the fridge, so let it stand at room temperature 10-20 minutes before serving or until it reaches the desired consistency.
Spoon it into individual glasses and serve it with fresh berries, pistachios, cookies, whipped cream, fudge sauce, chocolate shaves, you name it. If you don’t have enough or suitable glasses, you could also store it in an airtight container until serving or spoon it onto dessert plates.
How to store Chocolate Mousse?
Store Chocolate Mousse in an airtight container or in individual glasses sealed with plastic foil in the fridge up to 3 days.
Can Chocolate Mousse be frozen?
I don’t recommend freezing it because it changes its texture during the freezing and thawing process. Also, it can be that ice crystals develop within the air pockets in the chocolate mousse and when thawing they melt and make the mousse watery.
Is this Chocolate Mousse recipe safe for pregnant and toddlers?
Yes, because it doesn’t contain raw eggs. The egg yolks are cooked.

Add melted chocolate and whisk consistently. Transfer to a bowl and let cool completely. (If your chocolate ganache breaks, then read the blog post above to know how to fix the ganache easily.)
With a handheld or stand mixer fitted with a whisk attachment, whisk 3/4 cup heavy cream on medium-high speed until soft peaks form about 2-3 minutes. Add powdered sugar and whisk until stiff peaks form.
Stir 1/4 of the whipped cream into the cooled chocolate cream with a whisk. Then gently fold in the remaining whipped cream with a wooden spoon.
