These mouth-watering brownies combine the delicious flavours of chocolate, Vanilla and Cinnamon, with roughly chopped walnuts for addded crunch.
Pre-heat the oven to 180°C, 350°F, Gas Mark 4. Grease a 17.5cm x 27.5cm (7x11 inch) tin and line with greased greaseproof paper. Break the chocolate into pieces and place 100g (4oz) in a bowl over a pan of simmering water. When the chocolate has melted, remove the pan from the heat to cool slightly.
Split the Vanilla Pod open with a knife and carefully scrape the seeds into a bowl. Add the remaining ingredients to the bowl and beat them together for 1 minute. Beat in the melted and reserved solid chocolate. Spoon the mixture into the tin and bake for 18-20 minutes, until the cake has shrunk from the sides of the tin and springs back when lightly touched.
Leave the cake to cool and then cut into 12 pieces.
