Preheat your oven to 170°C fan / 190°C conventional. Grease and line two 20cm round cake tins with baking paper.
First, grate the carrot and finely chop the walnuts. Set aside for now.
200 g Carrots, 125 g Walnuts
Mix the sugar, eggs, oil and vanilla together in a bowl. Set the bowl aside.
300 g Light brown sugar, 4 medium Eggs, 300 ml Sunflower oil , 2 tsp Vanilla extract
In a separate large bowl, stir the flour, spices and orange zest together.
300 g Self-raising flour, 2 tsp Ground cinnamon, 0.5 tsp Ground nutmeg, 0.25 tsp Ground cloves , 1 large Orange
Pour the wet ingredients into the dry and fold together until the mixture is smooth combined.
Fold in the grated carrot and chopped walnuts until mixed through. If using sultanas, fold them in at this stage too.
Divide evenly between the baking tins and bake for 35-40 minutes until the cakes have risen and a toothpick inserted in the middle comes out clean.
Leave to cool in the tins for 10 minutes, then turn out onto a wire rack and cool completely.
