The roots of this cake are in Mother's Day. My mother-in-law wanted a chocolate cake so I decided to make her an over-the-top chocolate extravaganza. I succeeded. I've made it three or four times now, and I've given out the recipe several times.
This cake is an amalgam from two sources. The chocolate cake is simply the recipe from the back of the Hershey's Cocoa Tin. The mousse is lifted from one of my favorite books "The Modern Baker" by Nick Malgieri. It's worth purchasing for the pictures alone. (I am so addicted to food porn.)
Chocolate Mousse:
3 c. heavy whipping cream
1/3 c. sugar
6 large egg yolks
12 oz. best-quality milk chocolate
4 oz. bittersweet chocolate
Moistening syrup:
1/3 c. water
1/4 c. sugar
2 tsp. vanilla extract
Finishing:
1 c. heavy whipping cream
White (or milk) chocolate shavings
To make the mousse:
1. Combine 1 c. cream and the sugar in a medium saucepan and whisk. Place over low heat and bring to a boil. Meanwhile, whisk the egg yolks in a small bowl. When the liquid boils, whisk about 1/3 of it into the yolks. Return the liquid to a boil and, beginning to whisk before pouring, pour the yolk mixture into the boiling liquid. Whisk constantly until the cream thickens slightly - it won't be very thick - 10 to 15 seconds after adding the yolks. Remove the pan from the heat, never ceasing to whisk. Quickly strain the sauce into a bowl. Whisk the sauce continuously for about 30 seconds to cool it down so the yolks don't scramble.
2. Combine the chocolates in a large bowl and pour the hot custard cream over them. Shake the bowl to make sure all the chocolate is submerged, then let it stand for 2 minutes. Whisk until smooth and set aside to cool to room temperature.
3. Whip the remaining 2 c. cream until it holds a soft peak and refrigerate.
4. Quickly fold the cream into the cooled chocolate cream.
To assemble the cake:
1. Cut the cooled cakes so that you can make even layers. Put the first layer on the bottom of a prepared spring form pan. Use a brush to sprinkle the layer with half of the syrup.
2. Pour half the mousse on the cake layer and use a small offset spatula to spread it evenly.
3. Top with the other cake layer (carefully - don't press down) and repeat syrup and mousse. Refrigerate the cake to set the mousse.
4. Whip 1 c. cream and spread it smoothly all of the outside of the un-molded cake. Cover with white chocolate shavings.
Enjoy the presentation of the cake. It will soon be followed by "oh my god why is this so good?"
