From Modern Baking by Donna Hay

SERVES 10-12

250g store-bought plain chocolate biscuits
100g unsalted butter, melted
600g dark chocolate (45-55 per cent), chopped
125ml espresso coffee
310ml single cream
cocoa powder, for dusting

FOR THE WHIPPED MASCARPONE
375ml single cream
180g mascarpone

1. Place the biscuits and butter in a food processor and process until finely crushed. Press into the base and sides of a 25cm (1.5 litre-capacity) oval-shaped dish, using the back of a spoon. Refrigerate for 10 minutes or until firm.
2. Place the chocolate in the cleaned food processor and pulse until finely chopped. Place the coffee and cream in a small saucepan over high heat until almost boiling. Remove from the heat, add the chocolate and allow to stand for 5 minutes. Stir until melted and smooth. Pour into the dish over the biscuit base and refrigerate for 3-4 hours until set.
3. To make the whipped mascarpone, place the cream and mascarpone in the bowl of an electric mixer and whisk until soft peaks form. Spoon into a piping bag fitted with a 1.5cm round nozzle. Pipe the mascarpone mixture onto the surface of the chocolate layer (ganache). Dust the pie with cocoa to serve.
