Step‑by‑Step Instructions for Nutella Mousse Layer Cake
Step 1: Preheat and Prepare the Pan
Preheat your oven to 375°F (190°C) and prepare a 10-inch springform pan by greasing it generously with butter or non-stick spray. This will ensure your flourless chocolate cake can be easily removed after baking, allowing for a beautifully layered Nutella Mousse Layer Cake. Set it aside while you prepare the batter.
Step 2: Melt Chocolate and Butter
In a medium saucepan over medium heat, combine semisweet chocolate chips and butter, stirring continuously until melted and smooth. This process should take about 4-5 minutes. Once the mixture is glossy and homogenous, remove it from the heat and let it cool slightly while you prepare the dry ingredients.
Step 3: Mix Dry Ingredients
In a large mixing bowl, whisk together granulated sugar, salt, vanilla extract, large eggs, and cocoa powder until well combined. You’ll be looking for a smooth and creamy consistency. This base will give your Nutella Mousse Layer Cake its rich flavor. Once mixed, set it aside as you combine the chocolate mixture.
Step 4: Combine Mixtures
Pour the cooled chocolate and butter mixture into the bowl with the egg mixture, stirring gently until both mixtures are fully incorporated. The batter should be thick yet pourable, with a rich chocolaty aroma. Make sure there are no lumps for a smooth cake texture.
Step 5: Bake the Cake
Pour the combined batter into your prepared springform pan and spread it evenly. Bake in the preheated oven for 20-22 minutes. The cake is done when a toothpick inserted in the center comes out with a few moist crumbs. Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack.
Step 6: Layer with Nutella
Once the cooled cake is on the rack, generously spread a layer of Nutella over the top. Make sure to cover the cake completely for that luscious flavor in every bite. This layer of hazelnut deliciousness will act as a perfect base for your mousse.
Step 7: Prepare the Mousse Filling
In a mixing bowl, beat together cream cheese, heavy whipping cream, and sour cream on medium speed until the mixture is smooth and creamy. This should take about 3-4 minutes. The smooth texture will give your Nutella Mousse Layer Cake a delightful mouthfeel.
Step 8: Dissolve Gelatin
In a small bowl, dissolve unflavored gelatin in cold water and let it sit for about 5 minutes until it blooms. Once ready, combine this gelatin mixture with Nutella, stirring until well incorporated. This will ensure your mousse sets perfectly and holds its shape.
Step 9: Combine Mousse Ingredients
Gently fold the Nutella mixture into the cream cheese mixture until fully combined. The mixture will become light and airy, packed with Nutella flavor. Ensure there are no lumps to create a silky mousse that will layer beautifully on your cake.
Step 10: Spread the Mousse
Pour the Nutella mousse over the Nutella-covered cake, using a spatula to spread it evenly to the edges. Chill in the refrigerator for at least 2-3 hours to allow the mousse to set completely for your Nutella Mousse Layer Cake to hold its beautiful shape.
Step 11: Make the Buttercream
While the mousse is setting, prepare the Nutella buttercream by beating together softened butter, Nutella, powdered sugar, and a splash of heavy cream until the mixture is smooth and fluffy. This creamy topping will add another layer of deliciousness to your cake.
Step 12: Prepare the Ganache Topping
In a small saucepan, heat heavy cream until it starts to simmer, then pour it over semisweet chocolate chips in a bowl. Let it sit for a couple of minutes, then stir until it forms a shiny and smooth ganache. This glossy topping will create an impressive finish.
Step 13: Assemble and Chill
Spread the Nutella buttercream evenly over the set mousse, then pour the chocolate ganache over the buttercream layer. Use a spatula to smooth it out. Chill the fully assembled cake in the refrigerator for several hours or overnight to achieve the perfect texture and flavor development.
Step 14: Serve
Carefully release the Nutella Mousse Layer Cake from the springform pan and place it on a serving platter. You can garnish with Ferrero Rocher chocolates on top for a delightful touch. Slice and serve chilled for a show-stopping dessert that’s sure to impress!

Nutella Mousse Layer Cake Recipe FAQs
What type of chocolate should I use for the cake?
For the best flavor, use semisweet chocolate chips. They provide a rich, balanced taste that complements the Nutella perfectly. If you prefer a deeper chocolate flavor, dark chocolate is an excellent substitute.
How should I store the Nutella Mousse Layer Cake?
Store your cake in an airtight container in the refrigerator for up to 3-4 days. This keeps it fresh and maintains its creamy texture. If you have leftovers, make sure to cover them well to prevent any odors from the fridge affecting the cake.
Can I freeze the Nutella Mousse Layer Cake?
Absolutely! To freeze individual slices, wrap them tightly in plastic wrap, followed by aluminum foil. This will protect their flavor and texture. The cake can be frozen for up to 2 months. When you’re ready to enjoy, simply thaw the slices in the refrigerator for a few hours or overnight.
What if my mousse doesn’t set properly?
If your mousse is not setting, it might be due to the gelatin not dissolving properly. Make sure to let the gelatin bloom in cold water for about 5 minutes before mixing it with the Nutella. If you’re still having trouble, try refrigerating it a little longer; sometimes, mousse just needs extra chilling time to achieve the right consistency.
Are there any dietary considerations for this cake?
For those who are vegan, you can substitute the eggs with flax eggs (1 tablespoon flaxseed meal mixed with 2.5 tablespoons water per egg) and use coconut cream instead of heavy cream for the mousse and buttercream. Make sure to check labels for allergens, as Nutella contains hazelnuts and dairy.
How can I make a gluten-free version of the cake?
This Nutella Mousse Layer Cake is already gluten-free since it’s made with flourless chocolate cake! Just ensure that any chocolate chips or other ingredients used are certified gluten-free to prevent cross-contamination. Enjoy your delicious treat without worry!
