Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the Brownie Base:

1 cup Nutella
½ cup unsalted butter, softened
¾ cup granulated sugar
3 eggs, room temperature
1 tablespoon vanilla extract
1 cup all-purpose flour
3 tablespoons natural cocoa powder
½ teaspoon kosher salt

For the Mousse:

1 packet unflavored gelatin (about ¼ ounce)
4 tablespoons cold water
1 cup Nutella
1½ cups heavy whipping cream, divided
1/8 pinch kosher salt

For the Ganache:

1 cup Nutella
½ cup heavy whipping cream

Directions

Preheat the oven to 350°F (175°C). Spray a 9-inch springform pan with nonstick baking spray.
To prepare the brownie base, combine the softened butter and Nutella in a medium saucepan over medium heat. Whisk until smooth and melted.
Add the sugar and whisk until combined. Remove from heat and allow the mixture to cool slightly.
Whisk in the eggs and vanilla extract until smooth.
Stir in the cocoa powder, kosher salt, and flour until just combined. Avoid overmixing.
Pour the batter into the prepared springform pan and spread evenly.
Bake for approximately 30 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs attached.
Allow the brownie layer to cool completely in the pan.
For the mousse, sprinkle the gelatin over the cold water in a small bowl and let it stand for 5 minutes.
In a medium saucepan, combine 1 cup Nutella with ½ cup heavy whipping cream. Heat gently, whisking constantly, until smooth and just beginning to simmer.
Stir in the salt and softened gelatin until completely dissolved.
Strain the mixture through a fine-mesh sieve into a large mixing bowl and allow it to cool.
In a separate large bowl, whip the remaining 1 cup heavy cream until soft peaks form.
Fold half of the Nutella mixture into the whipped cream until combined. Gently fold in the remaining Nutella mixture.
Pour the mousse over the cooled brownie base and smooth the top.
Refrigerate overnight to allow the mousse to set completely.
For the ganache, combine the Nutella and heavy cream in a small saucepan over medium heat.
Whisk until smooth and fully melted.
Let the ganache cool for about 10 minutes.
Pour the ganache over the chilled mousse layer and spread evenly with a spatula.
Refrigerate for an additional 2 to 3 hours, or until the ganache is fully set.
Slice and serve chilled.

Storage/Reheating

Store the cake covered in the refrigerator for up to 5 days. Keep it in the springform pan or transfer slices to an airtight container.

This dessert is best enjoyed chilled and does not require reheating.

FAQs

Can I make this cake ahead of time?

Yes, this cake is ideal for making a day in advance since the mousse requires overnight chilling.

Can I use a different chocolate-hazelnut spread?

Yes, any similar chocolate-hazelnut spread can be substituted, although the flavor may vary slightly.

Why does the mousse need gelatin?

The gelatin helps stabilize the mousse so it sets properly and holds its shape when sliced.

Can I skip straining the mousse mixture?

Straining is recommended because it removes any undissolved gelatin or lumps, resulting in a smoother mousse.

How do I know when the brownie base is done baking?

A toothpick inserted near the center should come out with a few moist crumbs but no wet batter.

Can I freeze the finished cake?

Yes, the cake freezes very well for up to 2 months when properly wrapped.

What type of pan should I use?

A 9-inch springform pan works best because it allows for easy removal and clean presentation.

Can I use whipped topping instead of heavy cream?

Heavy cream is recommended for the best texture and stability, but whipped topping can be used in a pinch.

How can I make the cake even richer?

Add chopped chocolate to the brownie batter or drizzle melted chocolate over the ganache layer.

Should the cake be served cold?

Yes, serving it chilled helps maintain the structure of the mousse and ganache layers.
