Ingredients

  • 400 g light muscovado sugar
  • 300 ml light olive oil or other flavourless oil
  • 4 eggs about 200g
  • 240 g rice flour
  • 80 g oatflour or oats finely ground to a powder
  • 1 teaspoon cinnamon
  • ½ teaspoon ground ginger
  • ¼ teaspoon nutmeg
  • 1 teaspoon bicarbonate of soda
  • 2 teaspoons baking powder
  • ½ teaspoon salt
  • 340 g grated courgettes (about 4) squeezed to remove excess moisture

For the Icing

  • 500 g mascarpone
  • 2 tablespoons natural yoghurt
  • 2 tablespoons icing sugar
  • 1 lemon grated zest

Instructions

  • Pre-heat the oven to 170°C and line a grease a 13x9x4 inch baking tin.
  • In a large bowl (or stand mixer) beat together the sugar, olive oil and eggs until smooth and thick.
  • Add all the other ingredients in, except for the courgette, and beat until everything is fully mixed together.
  • Finally stir in the courgette until evenly dispersed and pour into the prepared baking tin.
  • Bake for 40 minutes, checking after 20 minutes and covering with foil if the cake seems to be browning too much.
  • When ready, leave the cake in the tin for 5 minutes to settle before turning out onto a wire rack and leaving to cool completely before icing.
  • To make the icing beat the mascarpone together with the yoghurt, icing sugar and lemon zest until light and smooth and spread onto the top of the cooled courgette cake with a palette knife.
