    Combine 300g of dark chocolate and the butter in a saucepan over low heat. Cook, stirring, for 5 mins or until melted. Set aside to cool slightly.
  3. Step 3

    Add the sugar and egg and stir to combine. Add the flour, cocoa and sour cream and stir to combine. Add the milk chocolate, white chocolate, remaining dark chocolate and the walnut. Gently fold until just combined. Pour into the prepared pan and smooth the surface.
