Base:
200g chocolate biscuits
55g brown sugar
100g butter, melted
Mousse-cheesecake:
120g chocolate, chopped
900g cream cheese, room temperature
15ml cocoa powder, sifted
375ml sugar
10ml vanilla
4 eggs
375ml cream
60ml icing sugar, sifted
Chocolate Ganache:
320g chocolate, chopped
300g cream
For the base:
Place the biscuits in a food processor and process to a fine crumb.
Spoon the biscuit crumbs into a mixing bowl and add the sugar and melted butter.
Mix together until it resembles wet sand.
Spoon the mixture into a 23cm loose-bottom cake tin and press evenly over the base.
Place in the refrigerator.
For the mousse-cheesecake:
Preheat your oven to 150℃.
Place the chocolate in a heatproof bowl set over a saucepan of simmering water and allow to melt until completely smooth.
Add the cream cheese, chocolate, cocoa powder and sugar to a mixing bowl and whisk with an electric mixer until incorporated.
Add the vanilla and eggs and whisk until the mixture is smooth and glossy. Set aside.
Add the cream to another mixing bowl and sift the icing sugar into the bowl.
Whisk until the cream develops a mousse-y texture and soft peaks form.
Fold the cream into the cream cheese mixture – do this in 3-4 batches. Fold until just incorporated.
Pour the cheesecake mixture into the cake tin with the biscuit base. Smooth the top and give the cake tin a jiggle to let out any air bubbles.
Place the cake tin soon top of a sheet of aluminium foil and fold the foil up the sides on the outside of the tin. Place the cake tin into a roasting pan and fill the pan with 2,5cm of hot water.
Bake the cake for 70 minutes. Check and refill the water in the roasting tin every 20 or so during baking.
Remove the cheesecake from the oven and immediately run a sharp knife around the outside of the cake to release it from the tin.
Allow the cheesecake to cool completely before removing the tin ring.
For the ganache:
Add the cream to a small saucepan and warm it.
Remove from the heat, add the chocolate and stir until the chocolate has melted and the mixture is smooth.
Set the cheesecake on a wire cooling rack, inside a baking sheet and pour the ganache over the cake.
Refrigerate for 30 minutes before serving.
