This is actually very easy to make and takes less than an hour. It is delicious and improves with good cream.
Chocolate-Glazed Hazelnut Mousse Cake
Gourmet February 2006
For shortbread base
• 2 tablespoons hazelnuts, toasted and skins rubbed off.
• 3 tablespoons sugar
• ½ cup all purpose flour (no sin stuff)
• ½ stick ( ¼ cup) unsalted butter
• 2 tablespoons unsweetened Dutch process cocoa powder (don’t know used Cadbury that I found in fridge)
• teaspoon salt
For mousse
• 1 teaspoon unflavoured gelatin
• 3 tablespoons cold water
• ½ cup chocolate hazelnut spread such as Nutella
• ½ cup mascarpone ( ¼ pound)
• 1 ½ cups chilled heavy cream
• 2 tablespoons unsweetened Dutch-process cocoa powder
• 3 tablespoons sugar
For Ganache
• ¼ cup plus 1 tablespoon heavy cream
• 3 ½ oz fine quality bittersweet chocolate
8-inch (20 cm) spring form pan
Make shortbread base:
Put oven rack in middle position and preheat oven to F (180 C). Invert bottom of spring form pan, then lock on side of pan and line bottom with round of parchment paper.
Pulse hazelnuts and sugar in a food processor until nuts are finely chopped. Add flour, butter, cocoa, and salt and pulse just until a dough forms.
Press dough evenly onto bottom of spring form pan with your fingers (what if I had said toes?). Prick all over with a fork, then bake until just dry to the touch (about 18 to 20 minutes). Transfer to rack to cool completely, about 30 minutes. Remove side of pan and slide out parchment from under shortbread, then reattach side of pan around shortbread base.
Make Mousse while shortbread cools:
Sprinkle gelatin over water in a 1 to 1 ½ quart heavy saucepan and let stand until softened, about 5 minutes. Heat gelatin mixture over low heat, stirring, just until gelatin is melted, about 2 minutes. Whisk in Nutella until combined and remove from heat.
Whisk together mascarpone and chocolate hazelnut mixture in a large bowl. Beat together cream, cocoa powder, and sugar with an electric mixer on low speed until just combined, then increase speed to high and beat until cream just holds soft peaks. Whisk one third of whipped cream into mascarpone mixture to lighten, then fold in remaining whipped cream until well combined.
Spoon filling onto shortbread base in pan, gently smoothing top, then chill, covered, at least three hours.
Make ganache and glaze cake:
Bring cream to a simmer in a small heavy saucepan and remove from heat. Add chocolate and let stand 1 minute, then gently whisk until completely melted and smooth. Transfer ganache to a small bowl and cool stirring occasionally, until slightly thickened but still pourable, about 20 minutes.
Run a warm thin knife around inside of spring form pan, then remove side (of pan). Slide cake off bottom of pan and transfer to a serving plate. Pour ganache onto top of cake and spread allowing excess ganache to drip down sides.
Cake without glaze can be chilled up to 2 days.
Cake can be glazed 6 hours ahead and chilled uncovered.
