Serves 6
550 ml double cream
250g mascarpone
75 ml Tia Maria
5 tbsp caster sugar
300 ml strong coffee (made with 2 tbsp good quality instant coffee granules and 300ml boiling water), cooled
175g pkt savoiardi (lady's fingers) sponge biscuits
50g dark chocolate (min 70% cocoa), refrigerated
2 tsp cocoa powder
1. Put the cream, mascarpone, Tia Maria and sugar in a large bowl.
2. Whisk until completely combined with no lumps and it has the consistency of thick whipped cream.
3. Put the coffee into a shallow bowl and dip in a few sponge fingers at a time, turning once or twice so they are nicely soaked, but not soggy.
4. Layer these into your chosen serving dish until you have used a third of the biscuits, then spread over a third of the cream mixture.
5. Using the coarse side of a cheese grater, grate over a third of the chocolate.
6. Then repeat the layers twice more, using up all the coffee, finishing with a cream layer, topped with grated chocolate.
7. Cover the dish and put in the fridge overnight for the flavours to blend.
8. To serve, dust with cocoa powder.
Keeps for 2 days in the fridge.
