.This is a redo of a post from the early days of my blog…in fact, I was such a novice, I didn’t even post a photo. Who does that??? Not sure if it was a flop, but I was willing to try again for the Chocolate Love Blog Hop. A layer of flourless chocolate cake topped by semisweet, then white chocolate mousse is surely chocolate love. Bill told me how fabulous this was at least three times. This would be perfect for your Valentine…it was for mine!
Triple Chocolate Mousse Cake…adapted from Cook’s Illustrated
For the bottom layer:
6 tablespoons butter, cut into pieces (plus extra for greasing the pan)
7 ounces semisweet chocolate, finely chopped
1/2 teaspoon instant espresso powder
1 1/2 teaspoons vanilla
4 eggs, separated
Pinch of salt
1/3 cup brown sugar
For the middle 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
For the top layer:
¾ teaspoon powdered gelatin
1 tablespoons water
6 ounces white chocolate, finely chopped
1½ cups heavy cream
For garnish:
Chocolate curls
To make the bottom layer, butter the bottom and sides of a high sided, 8-inch springform pan with 4 inch sides (9 inch diameter is OK, too). Center a rack in the oven and preheat to 325˚. 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 vanilla and egg yolks into chocolate. Set aside.
With stand or hand mixer, beat the egg whites and salt on medium speed until foamy, about 30 seconds. Crumble half of the brown sugar into the mixing bowl with your fingers to remove any lumps. Beat until incorporated, then add the remaining brown sugar and continue to beat on high speed until stiff peaks form. Using a whisk, mix one-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 completely incorporated. Pour the batter into the prepared springform pan and smooth the top with a spatula.
Bake until the cake has risen, is firm around the edges and the center has just set but is still soft (should spring back after pressing gently with a finger), about 23 minutes (14-18 minutes if using 9 inch pan). Transfer the cake to a wire rack to cool completely, at least 1 hour. Cake will fall. Do not remove the cake from the pan.
To make the second layer, whisk together the cocoa powder and hot water in a small bowl; set aside. Melt the chocolate gently in microwave, stirring occasionally until smooth. Once melted, remove from the heat and let cool slightly, 2-5 minutes.
Whip the cream, sugar and salt on medium speed until the mixture begins to thicken, then increase the speed to high and whip until soft peaks form. 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 completely incorporated. Pour the mousse into the springform pan over the cooled cake and tap gently on the counter 3 times to remove air bubbles. Carefully smooth the top with a spatula. Wipe down the inside edge of the pan to remove any chocolate. Refrigerate for at least 15 minutes while preparing the top layer.
To make the top layer, 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. In a large Pyrex measuring cup, microwave 1/2 cup of the cream till it starts to boil. Add the gelatin mixture to the cream 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, about 5-8 minutes, stirring occasionally.
Whip the remaining 1 cup of cream at medium speed 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 well incorporated. 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.
To serve garnish with chocolate curls or cocoa powder.

Nessie, it took a couple hours in the morning to make and cool the base layer, then another hour or so in the afternoon to make the top two layers. I hope you will try it!
Lots of patience went into this beauty. Chocolate Nirvana!
Thumbs up this time for the perfect layering done and the rolls of chocs on top. The cake sure looks heavenly and tempting for me.
Thanks for the comments on my blog Lizzy and I should be back by Wed home. Till then or if I can, will drop by to your blog.
This is incredible, triple the goodness. Actually triple plus 1 if we also count the garnish. There is probably no such thing as too much chocolate:)
GORGEOUS, Liz! Every layer is perfect! That is most certainly a 5-star dessert that would cost $$ per slice at most restaurants in NYC! My #chocolatelove post will be up tomorrow
This is an absolutely gorgeous cake!! And, even better, it’s already gluten-free so I can make it without any adaptations
. Fabulous #chocolatelove post!!
The cake looks fabulous. I like mousse cakes because they have less or no flour at all.
Wow…this one is definitely not a flop!! Glad you reposted as this is a show stopper dessert!
This is such a beautiful cake. I think it would be perfect for any occasion.
Perfection on a plate.

Oh, sweet, dark, chocolatey master – this looks incredible! My favourite dessert, in cake form?
Would I even need to cut a slice, or could I just spoon it out directly, like a mousse from a cup?! 
What a gorgeous desert…Since I love chocolate mousse…I think I would have to eat most of it by myself. Great idea for Valentines day!

I’m a behind on my linky party features, but just wanted to let you know that you’ve been featured on my blog today. http://acraftycook.blogspot.com/2012/04/1-month-of-fun-april-link-party-and.html
Thanks for the wonderful step by step tutorial on how to make this awesome cake!! I just tried this last weekend and it came out really well.
Happy Baking!
I have a question though- how and when did you remove the cake from the springform pan? I couldn’t think of moving the cake in 1 piece after it was all set in the pan. All I did was remove the side of the springform pan and serve it on the springform bottom.
Thanks again for the detailed & wonderful recipe! Only comment I have is the white chocolate layer was a bit sweet for me. Oh and I came across your cake/blog through pinterest!
