  • 2 eggs, beaten

  • With a food processor or table top mixer, beat cream cheese until smooth. Add chocolate mixture and blend until mixture is well-mixed and uniformly coloured. Add cream, vanilla, sugar and eggs. Beat well. Sieve cocoa powder over batter and pulse or mix on low speed until cocoa is thoroughly incorporated. Pour mixture over biscuit base in tin. Cover cake with a piece of parchment paper.
