Cheescake Brownies

I know I know, they sound completely bonkers I thought the same thing but I tried them and Oh my gosh I love them! This recipie involves a tiny bit of work and a bit of washing up but trust me they are so worth it.

Ingredients:
100g (4oz) dark chocolate chips
2 eggs
1/2 tsp vanilla essence
125g (5oz) soft butter
275g (11oz) caster sugar
75g (3oz) self-raising flour

Cheescake top:
200g (8oz) mascarpone
2 egg yolks
75g (3oz) caster sugar

Preheat the oven to 180°C (350°F) Gas mark 4. Grease and line a 20cm (8") at least 6 1/2cm (2 1/2") deep. Place the chocolate in a heatproof bowl over a pan of simmering water. Stir the chocolate untill completely melted and smooth, take the pan off the heat. Break the eggs in to small bowl and beat them. In a seperate bowl combine the vanilla, butter, sugar and eggs. Add the flour and cocoa and mix well. Stir in the melted choclate. In a different bowl mix together the cheescake mixture untill smooth, blob on heaped spoons of the mixture on to the brownie and swirl together using a skewer. Bake for 35 minutes or untill a skewer inserted comes out ever so slightly wet. Leave in the tin to cool for 10 minutes before turning on to a wire rack. Cut into slices and enjoy!
