Layered Mousse Cake #SundaySupper

A group of girlfriends gathered for a holiday luncheon the week before Christmas. I volunteered to bring dessert, natch. Once it was decided we’d surprise one of our friends for her upcoming birthday, I knew it had to be special. I went deep into my archives to retrieve an exquisite recipe for this Layered Mousse Cake. It was a huge hit with my friends.

Layered Mousse Cake

I’ve made so many chocolate mousses and mousse cakes that I’ve lost count. Every iteration I’ve seen, I’ve tried. This is one, though, that I’ve made more than once. It’s memorable. It’s decadent. It’s a show stopper. My friend, Shelli, has a birthday the same day as my son, Tom. Two days after Christmas. Lost in the shuffle of the holidays. We were going to make sure she knew we loved her. There was swooning after the sampling of this layered mousse cake began. If you need a special dessert, this is the one for you!!

National Sunday Supper Month!

I’ve been with this Sunday Supper group since nearly its inception…nearly 4 years ago. I think my first Sunday Supper post featured these Parisian Cheese Puffs for our Oscar party on February 26, 2012! To celebrate, January has been declared National Sunday Supper month. We are all focusing on great food and family–just what the Sunday Supper mission is all about. I love this Sunday Supper pledge—feel free to check the link below the list of recipes and take the pledge! Plus, make sure to check out all the amazing recipes this week—we have a huge number of participants for this special event!

Layered Chocolate Mousse Cake and Sunday Supper pledge

I believe in Sunday Supper …

Because it brings my family together to share joys and challenges.

Because it starts as one day and soon becomes more.

Because it teaches us the importance of unplugging and being present.

Because it makes me closer to the ones I love.

Because it allows us to nourish each other in both body and mind.

Because it creates cherished memories and traditions of togetherness.

Because it celebrates good food and homemade meals.

Because it cements a legacy of strong families.

A decadent, 3 layer chocolate mousse cake that will thrill the chocoholics in your life! Adapted slightly from Cook's Illustrated.
Ingredients
Bottom layer:
  • 6 tablespoons butter, cut into pieces (plus extra for greasing the pan)
  • 7 ounces semisweet chocolate, finely chopped
  • ¾ teaspoon instant espresso powder
  • 1½ teaspoons vanilla extract
  • 4 eggs, separated
  • Pinch of salt
  • ⅓ cup brown sugar
Chocolate Mousse Layer
  • 2 tablespoons Dutch-processed cocoa powder
  • 5 tablespoons. hot water
  • 7 ounces semisweet chocolate, finely chopped
  • 1½ cups heavy cream
  • 1 tablespoon granulated sugar
  • Pinch of salt
White Chocolate Mousse:
  • ¾ teaspoon powdered gelatin (I use Knox)
  • 1 tablespoon water
  • 6 ounces white chocolate, finely chopped
  • 1½ cups heavy cream
For garnish:
  • Chocolate curls
Instructions
  1. To make the bottom layer, butter the bottom and sides of a 9-inch springform pan. Center a rack in the oven and preheat to 325º. Combine the butter, chocolate, and espresso powder in a large heatproof bowl set over simmering water. Stir occasionally until the mixture is smooth. Remove from the heat and let cool slightly, about 5 minutes. Whisk in the vanilla and egg yolks. Set aside.
  2. In a stand mixer, beat the egg whites and salt on medium speed until foamy. Crumble the brown sugar into the egg whites and mix to incorporate. Continue to beat on high speed until stiff peaks form, a minute or two longer. Using a whisk, mix about a third of the beaten egg whites to the chocolate mixture to lighten it. Fold in the remaining egg whites gently with a rubber spatula until no streaks remain. Pour the batter into the prepared springform pan and smooth the top with a spatula.
  3. Bake until the center of the cake has just set but is still soft (should spring back after pressing gently with a finger), about 14-18 minutes. Cool completely on a wire rack.
  4. To make the second layer, whisk together the cocoa powder and hot water in a small bowl; set aside. Melt the chocolate in a heatproof bowl set over simmering water, stirring occasionally until smooth. Once melted, remove from the heat and let cool slightly, 2-5 minutes.
  5. In the clean bowl of a stand mixer fitted with the whisk attachment, whip the cream, sugar and salt on medium speed until the mixture begins to thicken, about 30 seconds. Increase the speed to high and whip until soft peaks form when the whisk is lifted, 30-60 seconds. Whisk in the cocoa powder mixture until smooth. Using a whisk, mix one-third of the whipped cream to the chocolate mixture to lighten it. Fold in the remaining whipped cream gently with a rubber spatula until no streaks remain. Pour the mousse into the springform pan over the cooled cake and tap gently on the counter a few times to remove the air bubbles. Smooth the top with a spatula. Wipe off any mousse that has dripped on the interior of the pan. Refrigerate while preparing the top layer.
  6. Sprinkle the gelatin over the water in a small bowl and let stand at least 5 minutes to soften. Place the white chocolate in a medium bowl. Bring ½ cup of the cream to a boil in a small saucepan. Remove the pan from the heat, add the gelatin mixture and stir until dissolved. Pour the hot cream mixture over the white chocolate and let stand about 1 minute. Whisk until the mixture is smooth. Cool to room temperature, stirring occasionally.
  7. Whip the remaining 1 cup of cream until it begins to thicken. Increase the speed to high and whip until soft peaks form. Using a whisk, mix one-third of the whipped cream to the white chocolate mixture to lighten it. Fold in the remaining whipped cream gently with a rubber spatula until no streaks remain. Spoon the white chocolate mousse into the pan over the middle layer. Smooth the top with an offset spatula. Return the cake to the refrigerator and chill until set, at least 2½ hours.
  8. Garnish with chocolate curls if desired.

  30. Hi Liz,
    I plan to make this for a party on Saturday. How much of it could I make ahead and how long would it keep? The party is Saturday evening. Ideally, I’d like to make the parts ahead of time and assemble it the morning of the party. Do you think that would work?

    Thanks!
    Kim

  38. I’m not usually much of a fan of mousse but this looks so pretty I think I’d definitely have to try some!
