My Nutella mousse cake features a fudgy brownie base, silky mousse center, and an amazing Nutella ganache. This tastes better than anything you'll find at your local bakery!
Preheat oven to 350 degrees. Spray 9 inch springform pan with nonstick baking spray.
In a medium saucepan over medium, whisk butter and Nutella until melted and smooth.
Whisk in sugar and cool.
Then whisk in eggs and vanilla. Then stir in cocoa, salt, and flour until just combined.
Pour batter into prepared pan and bake for around 30 minutes or until a toothpick inserted near the center comes out with just moist crumbs. Cool completely.
For the Mousse
In a small bowl, add gelatin to cold water and let sit for 5 minutes.
In a medium sauce pan, combine Nutella and ½ cup of the heavy cream. Bring to a simmer whisking until combined.
Stir in salt and gelatin. Strain through a fine mesh strainer into a large mixing bowl. It's okay if its starting to thicken already. Cool.
In a large bowl, beat remaining heavy cream until soft peaks form.
Fold half the Nutella mixture into the cream. Repeat with remaining cream.
Pour over the brownie layer and refrigerate overnight.
For the Ganache
In a small saucepan over medium heat whisk Nutella and cream until melted.
Cool for 10 minutes. Pour over top of mousse and smooth with a spatula.
