BAKED CHOCOLATE CHEESECAKE

Steps:

• Preheat the oven to 170°C/gas mark 3.
• Melt the chocolate and 125g of sugar in a bain-marie (a bowl suspended over a pan of simmering water). Set aside to cool slightly.
• Meanwhile make the biscuit base by mixing together the crushed digestives, melted butter and sugar. Press into a 20cm spring-form tin.
• In a large bowl, beat the cream cheese, remaining caster sugar, soured cream, vanilla extract and eggs until well-mixed.
• Pour half the mixture into the bowl with the melted chocolate and mix in thoroughly.
• Spoon in alternate amounts of the plain vanilla mixture and the chocolate one onto the biscuit base. Bake for 50 minutes until firm, cool before serving.
