568ml pot double cream
250g tub mascarpone
5 tbsp golden caster sugar
300ml strong coffee, made with 2 tbsp coffee granules and 300ml boiling water
175g pack sponge finger
25g chunk dark chocolate
2 tsp cocoa powder
Put a 568ml pot double cream, 250g tub mascarpone, 75ml marsala and 5 tbsp golden caster sugar in a large bowl.
Whisk until the cream and mascarpone have completely combined and have the consistency of thickly whipped cream. Pour 300ml strong coffee (made with 2 tbsp coffee granules and 300ml boiling water) into a shallow dish.
Dip in a few of the 175g pack of sponge fingers at a time, turning for a few seconds until they are nicely soaked, but not soggy. Layer these into your dish until you have used half the sponge fingers, then spread over half of the creamy mixture.
Using the coarse side of the grater, grate over most of the 25g dark chocolate. Then repeat the layers (you should use up all the coffee), finishing with the creamy layer.
Cover and chill for a few hours or overnight. This can now be kept in the fridge for up to 2 days.
To serve, dust with 2 tsp cocoa powder and grate over the remainder of the chocolate.
