Beat egg yolks and sugar in large bowl with electric mixer for 5 mins, or until pale and thick. Beat in melted chocolate mixture until combined.
Beat egg whites in medium bowl with electric mixer until soft peaks form. Fold into chocolate mixture, in 2 batches. Pour into prepared pan; smooth surface. Bake for 17 mins. Cool in pan on a wire rack.
Place ice cream in bowl; stir with wooden spoon until just softened. Spread over cake in pan; smooth surface. Cover with foil; freeze overnight.
Melt milk chocolate in heatproof bowl set over a saucepan of simmering water (don't let water touch bottom of bowl); stir until smooth. Remove from heat; cool until just warm.
Meanwhile, beat cream in large bowl with electric mixer until firm peaks form. Whisk slightly warm milk chocolate into cream. Pour over ice cream layer; smooth surface. Freeze overnight.
