Triple Nutella Mousse Cake Ingredients
For the Brownie Base
• Nutella – Essential for both layers, it provides that deep chocolate richness that defines this cake.
• Unsalted Butter (½ cup) – Adds a luscious moisture; feel free to substitute with salted butter if needed.
• Granulated Sugar (¾ cup) – Sweetens the brownie while balancing the overall cake sweetness; consider reducing to ½ cup for a less sweet taste.
• Eggs (3 large) – Provides structure; make sure they’re at room temperature for a smooth emulsion.
• Vanilla Extract (1 tablespoon) – Enhances the flavor profile; opt for pure vanilla for a more intense taste.
• All-Purpose Flour (1 cup) – Gives structure to the brownie; gluten-free flour blends can be used for a gluten-free option.
• Dutch-Process Cocoa Powder (3 tablespoons) – Deepens the chocolate flavor and contributes to the texture; unsweetened cocoa works as a substitute if needed.
• Salt (½ teaspoon + ⅛ teaspoon) – Balances sweetness; one for the brownie and another for the mousse.
For the Mousse Layer
• Plain Gelatin Powder (2 ¼ teaspoons or 1 packet) – Sets the mousse layer; agar-agar can be used for a vegetarian alternative.
• Cold Water (4 tablespoons) – Activates the gelatin for the perfect mousse consistency.
• Heavy Cream (1 ½ cups, divided) – Whipped for the mousse and combined with Nutella for the ganache; lighter cream can be an option for a fluffier texture.
For the Ganache Topping
• Nutella for Topping (1 cup) – Creates a beautiful glossy ganache layer on top, enhancing the overall appeal of this Triple Nutella Mousse Cake.
Step‑by‑Step Instructions for Triple Nutella Mousse Cake
Step 1: Prepare Brownie Base
Preheat your oven to 350ºF (175ºC). Line a 9-inch springform pan with foil and spray it with non-stick spray to prevent sticking. In a saucepan over medium-low heat, melt together the Nutella and unsalted butter until smooth, stirring continuously. Allow the mixture to cool slightly before whisking in the granulated sugar, eggs, and vanilla extract until well combined.
Step 2: Combine Dry Ingredients
Sift the all-purpose flour, Dutch-process cocoa powder, and salt into the Nutella mixture. Gently fold the dry ingredients into the wet ingredients until just combined, creating a thick and fudgy batter. Pour the brownie batter into the prepared springform pan, spreading it evenly. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out mostly clean. Let it cool completely at room temperature or refrigerate for 20 minutes.
Step 3: Make Mousse Layer
While the brownie base is cooling, sprinkle the gelatin over 4 tablespoons of cold water in a small bowl, allowing it to sit for 5 minutes. In a saucepan, warm ½ cup of cream and the remaining Nutella over low heat until melted, then remove from the heat. Stir in the salt and dissolved gelatin until fully combined, then let the mixture cool to room temperature.
Step 4: Fold in Whipped Cream
In a separate bowl, whip the remaining heavy cream to soft peaks. Gently fold the whipped cream into the cooled Nutella mixture, being careful not to deflate the airy texture. Once fully combined, spread the luscious mousse layer evenly over the cooled brownie base. Refrigerate the cake for at least 2 hours, allowing the mousse to set perfectly.
Step 5: Prepare Ganache Topping
For the ganache, warm the remaining Nutella and ½ cup of cream in a saucepan over low heat. Whisk the mixture until smooth and silky, allowing it to cool for about 10 minutes to thicken slightly. Pour the ganache over the mousse layer, smoothing it gently with a spatula to create a glossy finish. Refrigerate the cake again for at least 1 hour, ensuring the ganache sets firmly.
Step 6: Serve the Cake
Once set, carefully release the sides of the springform pan and remove the foil. Slice the Triple Nutella Mousse Cake into generous pieces using a hot knife for clean cuts. Serve chilled, optionally garnishing with fresh whipped cream or a few berries for added elegance. Relish each heavenly bite of this decadent dessert!

Storage Tips for Triple Nutella Mousse Cake
Fridge: Keep the cake refrigerated in an airtight container for up to 3 days to maintain its freshness and flavor.
Freezer: The Triple Nutella Mousse Cake can be frozen for up to 3 months. Wrap it tightly in plastic wrap and then foil to prevent freezer burn.
Thawing: To enjoy your cake after freezing, thaw it overnight in the refrigerator. This preserves the textures and flavors beautifully.
Reheating: There’s no need to reheat this cake; serve it chilled for the best taste experience!
Make Ahead Options
These Triple Nutella Mousse Cakes are perfect for those busy weeknights! You can prepare the brownie base up to 24 hours in advance; simply bake and cool it before covering it tightly with plastic wrap to keep it fresh. The mousse layer can also be made ahead and refrigerated for up to 3 days. Prepare the ganache the day before serving, and let it cool before pouring it over the set mousse layer. When you’re ready to impress your guests, simply slice and serve, adding a dollop of whipped cream or fresh berries for an elegant touch. This way, you’ll enjoy a show-stopping dessert without the last-minute rush!

Triple Nutella Mousse Cake Recipe FAQs
How do I choose the right Nutella?
Absolutely! When selecting Nutella, look for a smooth, creamy texture without any separation or dark spots. If you need an alternative due to allergies, opt for a high-quality chocolate hazelnut spread. Just ensure it has a similar flavor profile to maintain the richness of your Triple Nutella Mousse Cake.
What’s the best way to store the cake?
You can keep the Triple Nutella Mousse Cake refrigerated in an airtight container for up to 3 days. To maintain its texture, ensure it’s well-wrapped to prevent it from drying out or absorbing odors from the fridge.
Can I freeze the Triple Nutella Mousse Cake?
Yes, you can! I often freeze this cake to enjoy later. Wrap it tightly in plastic wrap followed by aluminum foil. It can be frozen for up to 3 months. When you’re ready to enjoy it, place it in the fridge overnight to thaw before serving, to keep its delicious layers intact.
Why is my mousse not setting properly?
Very good question! If your mousse isn’t setting, it may be due to the gelatin not fully dissolving. Ensure you stir the gelatin mixture until it’s completely dissolved in warm water before mixing it with the Nutella mixture. Let it cool slightly before folding in the whipped cream to achieve a light texture without curdling.
Is there a vegetarian option for this recipe?
Yes! For a vegetarian version, replace the plain gelatin with agar-agar. Use 1:1 ratio, but check the packaging for specific instructions, as agar sets differently. Dissolve it in boiling water first, then mix it into the mousse for a perfect texture.
Can I make this cake gluten-free?
Of course! Simply substitute the all-purpose flour with a gluten-free flour blend, ensuring it measures the same as traditional flour. Also, be cautious of cross-contamination if you have severe gluten allergies; opt for certified gluten-free ingredients to be safe.
