  1. Preheat oven to 180°C (160°C fan-forced). Lightly grease the base and sides of a deep 33×24 baking pan, line base and short sides with a sheet of baking paper.
  2. Using electric beaters, beat eggs in a medium bowl until thick and creamy, gradually add sugar, and beat well after each addition.
  3. Add the rind and juice, beat until well combined. Slowly add the olive oil, beating until well combined and mixture is thick and creamy. This should take about 3 minutes.
  4. Gently fold in carrot, zucchini, flour, cinnamon and walnuts. Pour cake mixture into pan.
  5. Bake for 30-35 minutes. Stand cake in pan for 10 minutes before turning onto a wire rack to cool.
  6. For Lemon Icing; Sift icing sugar into a bowl, add zest, then blend in lemon juice and butter with a spoon, mix well. Heat uncovered for 40-45 seconds in the microwave (or over a bowl of hot water), stir until smooth and shiny.
  7. Pour icing over cake, spreading roughly with a spatula and garnish with the sunflower seed mix.


Lyndey’s note: Use a fruity extra virgin olive oil for a more distinct flavour in this moist cake.
