Marbled Brownies

INGREDIENTS:
For the chocolate mixture:
8oz (225g) plain chocolate
3oz (85g) butter
4 eggs
10 and 1/2 oz (300g) sugar
5oz (140g) plain flour
1/2 teaspoon salt
1 teaspoon baking powder
2 teaspoons vanilla essence
4oz (115g) walnuts, chopped

For the plain mixture:
2oz (55g) butter, room temperature
6oz (170g) cream cheese
3 and 1/2 oz (100g) sugar
2 eggs
1oz (30g) plain flour
1 teaspoon vanilla essence

DIRECTIONS:
1) Preheat a 180C oven. Line a 13x9in (33x23cm) tin with greaseproof paper and grease.
2) Melt the chocolate and butter over very low heat, stirring constantly. Set aside to cool.
3) Meanwhile, beat the eggs until light and fluffy. Gradually add the sugar and continue beating until blended. Sift over the flour, salt and baking powder and fold to combine.
4) Stir in the cooled chocolate mixture. Add the vanilla and walnuts. Measure and set aside 16 fl oz (450 ml) of the chocolate mixture.
5) For the plain mixture, cream the butter and cream cheese with an electric mixer.
6) Add the sugar and continue beating until blended. Beat in the eggs, flour and vanilla.
7) Spread the unmeasured chocolate mixture in the tin. Pour over the plain mixture. Drop spoonfuls of the reserved chocolate mixture on top.
8) With a metal palette knife, swirl the mixtures to marble. Do not blend completely. Bake until just set, 35-40 minutes. Turn out when cool and cut into squares for serving
