Mary Berry's twist on a traditional Italian tiramisu is a tempting and sumptuous cake, rich with coffee, cream and chocolate. A very grown-up celebration cake!
From the book
Look out for the soft Italian sponge fingers called savoiardi, which are available from good delicatessens, to replace the trifle sponges. This dessert freezes well.
|1 generous tsp
|instant coffee granules
|120ml (4fl oz)
|85ml (3fl oz)
|300ml (½ pint)
|double cream (not extra thick)
|packet trifle sponges
You will need a round 20–23cm (8–9in) loose-based springform cake tin.
Line a round 20-23cm (8-9in) loose-based springform cake tin with non-stick baking parchment. Dissolve the coffee in the boiling water and mix with the brandy.
Break the eggs into a bowl, add the sugar and whisk together at high speed until thick and frothy – the mixture should leave its own trail when trickled from a height. Blend a little of this mixture with the mascarpone in another bowl, then stir in the remaining egg and sugar mixture.
Whisk the cream until thick and fold into the egg and mascarpone mixture. Coarsely chop the chocolate chips in a food processor to give chocolate bits and powder.
Split the sponge fingers and line the prepared tin with half of them. Sprinkle over half the coffee mixture and scatter over one-third of the chocolate, then add half the mascarpone mixture. Add a second layer of sponge, then the remaining coffee mixture and another third of the chocolate.
Cover with the rest of the mascarpone mixture and sprinkle with the remaining chocolate. Chill for four hours, then turn out of the tin, remove the parchment and serve very cold.
