Soak gelatine in a bowl of cold water for 5 minutes to soften. Meanwhile, place 1 cup (250ml) cream and 1 cup (220g) sugar in a pan over medium-low heat, stirring until sugar dissolves. Bring to just below boiling point, then remove from heat.

Squeeze excess water from gelatine, then stir into cream mixture until melted and combined. Set aside to cool. Place vanilla and cream cheese in a stand mixer fitted with the whisk attachment. Whisk on high until very smooth. In 3 batches, add the cooled cream mixture, whisking well between each addition.

Add 600g mascarpone and remaining 2 tbs Marsala, and whisk to combine (be careful not to overmix). Spread cream cheese mixture over the sponge biscuits and cover surface with plastic wrap. Chill overnight.
The next day, to make ganache, place chocolate in a heatproof bowl. Place remaining 3/4 cup (185ml) cream in a pan over medium heat. Bring to a simmer, then pour over chocolate. Set aside for 30 seconds to melt, then stir until smooth. Cool, then pour over cake. Chill for 2 hours.

Combine reserved espresso mixture with remaining 1/4 cup (55g) sugar in a saucepan over medium heat, stirring until sugar dissolves. Simmer for 5 minutes or until slightly thickened. Cool.
