Line a 33cm x 23cm x 5cm (13in x 9in x 2in) roasting tin with greaseproof paper, leaving excess hanging over sides. Mix together biscuits, almonds and butter; press into the base. Chill.
Step 2
Preheat oven to 170°C (150°C fan) mark 3. Melt chocolate in a bowl set over a pan of just simmering water (the bowl shouldn't touch the water). Don't stir, or it will congeal. Cool slightly.
Step 3
In a clean bowl, whisk the egg whites until they form soft peaks. Add 25g (1oz) sugar and whisk until stiff peaks form. In a separate bowl, using the same whisk - no need to wash - mix cream cheese, remaining sugar, yolks and vanilla.
Step 4
Using a large metal spoon, stir a spoonful of egg white into cheese mixture. Carefully fold in remaining whites. Put a quarter of the mix into the egg white bowl and fold chocolate into it.
Step 5
Pour vanilla mix over the biscuit base, then dollop spoonfuls of chocolate mix on top and marble using a knife. Bake for 45min or until set in the middle. Cool in tin. Chill for 2hr. To serve, remove from dish and dust with icing sugar.
Complete recipe, without icing sugar, up to two days ahead or freeze for up to a month. Keep in the dish, wrapped in clingfilm. To serve, if frozen, thaw in the fridge overnight; remove 1hr before serving. Dust with icing sugar and serve.
