Chocolate Nut Slice - cooking recipe

Ingredients

250 g unsalted butter
1 1/2 cups caster sugar
1 cup plain flour, sifted
1 cup walnuts, chopped
1 cup hazelnuts, chopped
3 free-range eggs
1 free-range egg yolk
225 g good quality dark chocolate

Preparation

Preheat the oven to 180\u00b0C.
In a small saucepan or a stainless steel bowl over a larger saucepan of simmering water, melt the butter and chocolate, stirring until combined.
In a large bowl, beat the eggs, yolk and sugar until pale.
Fold in the chocolate mixture, flour and nuts until just combined.
Spread the mixture into a greased tin (about 20cm x 20cm) and bake for about 25-30 minutes until a skewer inserted comes out moist (but not sticky and wet).
Allow to cool in the tin before cutting into rectangles.
