Preheat the oven to 160'C. Grate the carrot and chop the walnuts. Zest the orange. Mix all of the ingredients together and then pour into your cake mould and bake for 35-40 minutes. Insert a skewer into the centre of the cake - if it comes out clean, the cake is ready. Remove from the oven and allow to cool before icing.
Sieve the icing sugar into the cream. Split the vanilla pod in half and scrape out the seeds. Whip the cream with a whisk until soft peaks form and then use to top the cake.
