Put the biscuits in a food processor and whiz to crumbs, then mix in the melted butter. Press into the base of a 20.5cm (8in) springform cake tin lined with non-stick baking parchment. Chill.
Step 2
Preheat the oven to 180ºC (160ºC fan) mark 4. Meanwhile, melt the chocolate in a heatproof bowl set over a pan of gently simmering water, making sure the base of the bowl doesn't touch the water. Remove from heat and allow to cool a little.
Step 3
In a large bowl, beat together the mascarpone, ricotta, eggs, sugar, vanilla extract and melted chocolate. Spoon over the biscuit base and bake for 1-11/4hr or until golden on top but slightly wobbly in the middle. Turn off the oven and leave cheesecake inside to cool.
Step 4
Decorate with cocoa-dusted almonds and dust with cocoa.
