This Ferrero Rocher Mousse Cake sounds, looks, and tastes incredible. Inspired again by the irresistible Ferrero Rocher truffles this mousse cake is made of a chocolate hazelnut sponge cake at the bottom topped with an amazing crunchy hazelnut streusel, covered in a silky smooth Nutella mousse, and topped with chocolate glaze.
I found the crunchy hazelnut streusel the star of this cake. It is made with a baked hazelnut biscuit, that is then turned into crumbs and mixed with paillete feuilletine and Nutella. It pairs perfectly with the smooth Nutella mousse creating a decadent elegant dessert perfect for any occasion that resembles the worldwide known truffles.
It’s really not a difficult recipe, each step is easy to prepare and the results are simply wonderful. Decorate it with Ferrero Rocher Truffles for a more impressive look.
How to make Ferrero Rocher Mousse Cake
Foe this recipe you need to follow our easy instructions in the order presented here and you will get amazing results each time.
Prepare the chocolate sponge cake.
Begin by preheating your oven to 325F (160C) and generously grease an 8-inch (20cm) pan, lining it with parchment paper for easy removal.
Next, separate the egg whites from the yolks. Add a pinch of salt to the whites and whip until they turn foamy. Gradually add sugar, continuing to whip until stiff peaks form. Gently fold in the beaten egg yolks, ground hazelnuts, and cocoa powder.
Pour the batter into your prepared pan and bake for 15-20 minutes, being careful not to overbake. Once done, let it cool completely.
Prepare hazelnut streusel.
Begin by mixing butter, sugar, and a pinch of salt. Gradually incorporate hazelnuts and flour until the mixture is uniform. Roll the dough thin between two sheets of parchment paper or plastic wrap, then refrigerate for 30 minutes before baking. Once baked to a golden hue (about 20-25 minutes), let it cool before breaking it into crumbs. Combine the crumbs with pailleté feuilletine, gently folding in Nutella for an added layer of bliss.
Now, using a cake ring, cut the sponge into a 7-inch (18cm) disk and place the ring around it. Spread the crunchy hazelnut mixture on top, and freeze as you prepare the divine Nutella mousse.
Prepare the Nutella mousse
For the mousse, melt chocolate and ½ cup of whipping cream over a bain-marie. Add Nutella and stir until combined. Soak gelatin powder in water for 5-10 minutes, then dissolve it over low heat. Pour this mixture into the chocolate blend.
In a separate bowl, whip chilled cream until soft peaks form. Combine it with the chocolate mixture and transfer the mousse into a piping bag fitted with a plain tip.
Assemble the cake
Assemble the cake by placing the frozen sponge crunch in the center of a serving platter. Top it with an 8-inch (20cm) ring lined with an acetate sheet for easy removal. Pipe the mousse on the sides and top, smoothing it with an offset spatula.
Cover and refrigerate for 4-6 hours or overnight.
Prepare the chocolate glaze
Melt chocolate and cream over a gentle heat. Create drips around the edges, then fill the top with the ganache and spread evenly with an offset spatula. Refrigerate for at least 30 minutes before decorating with Ferrero Rocher truffles, chocolate shards, and chopped hazelnuts.

Which chocolate do you use (cacao percentage)
Hello Ksenia.
I use semisweet chocolate 55-70 % cacao.
Is it possible to make this without gelatin?
Can I leave out the gelatin?
Such a marvellous cake! I was wondering if you could eat it like an ice cream cake (which means keeping it in the freezer and eating it as soon as I take it out of it) and, if so, how many days can it stay in the freezer? Thank you and keep up the Amazing work
I’ve have baked this cake twice! It’s so delicious and I love ferrero rocher wich this cake really remind me of! <3
I tried this cake yesterday for my dads birthday and he absolutely loved it, so did I. It was delicious and it did turn out great. Thank you so musch for this recipe and I will do this cake many times again. 🍰🥳
So happy to hear that Klara 🙂 Happy birthday to your dad:)
I made this cake for my niece’s engagement party, and it was the star of the evening. Beautiful and delicious. The nut crunch is definitely the best part.
Thanks for this and all your wonderful recipes.
I am so happy to hear that Yechiel. That is so rewarding for me. Have a Happy New Year!
Can I layer cake in springform pan and not use the 7 in circle
Sure.. you can leave the sponge as is and don’t cut with a smaller ring.
The best cake ever! An amazing combination of flavours and textures!
I tried making this cake and it was a hit. Everyone absolutely lived it.
I am thinking of making it again but for a bigger crowd. How do I scale up to make a 23 inch cake instead?
I am so glad you enjoyed this cake. It is one of my favorites too. I suppose you want to make a 23cm (9inch) cake. All you have to do is to multiply every ingredient with 1,15. For instance instead of using 70g sugar you will need to use 70*1,15=80.5g sugar. Let me know if it is clear for you 🙂
