Mocha Mousse Cake

Instructions

• 1Grease a 22cm round springform pan. Line the base and side with parchment paper.
• 2Place 50g chocolate, 100g butter and honey in a heatproof bowl over a saucepan of simmering water (make sure the base of the bowl doesn’t touch the water). Stir with a metal spoon until melted and smooth. Remove from the heat.
• 3Place the biscuits in a food processor and process until finely crushed. Add the biscuit crumbs to the chocolate mixture and stir to combine.
• 4Spread the crumb mixture over the base of the prepared pan. Refrigerate for 30 minutes.
• 5Meanwhile, place the remaining 300g dark chocolate and 25g butter in a large heatproof bowl over a saucepan of simmering water (make sure the base of the bowl doesn’t touch the water). Stir with a metal spoon until melted and smooth. Remove from heat. Set aside for 5 minutes to cool slightly. Stir in the egg yolks until combined.
• 6Assemble the mixer with the whisk attachment. Add the egg whites to the large mixer bowl. Slowly turn mixer to AERATE/WHIP setting and beat the egg whites until firm peaks form.
• 7Assemble the mixer with the scraper whisk and the small mixer bowl. Place the cream and coffee in the small mixer bowl and attach the pouring cover. Slowly turn the mixer to CREAMING/BEATING setting and beat for 2 minutes, or until very soft peaks form.
• 8Add half the cream mixture to the chocolate mixture and stir until combined. Gently fold through half of the egg whites and mix until combined. Repeat with the remaining cream mixture and egg whites.
• 9Spoon the mixture over the biscuit base and level the surface. Refrigerate for 8 hours or overnight until set.
• 10To serve, dust the cake with cocoa powder and top with chocolate curls.
  Tip: Digestive biscuits are semi-sweet Scottish cookies. Look for them in the international section of large grocery stores with other items from the U.K.
