Grapefruit Yoghurt Cake

Yoghurt cake is a simple French classic and is very often the first cake that kids learn to bake as you are using the yoghurt pot as the measuring tool. It is moist, fluffy and works perfectly with grapefruits. 


  • No grapefruit? Try with any citrus you have on hand. Orange, clementines, satsumas, mandarins, or even the juice and zest of lemons. If using less citrus juice, only use 2.5 pots of flour. 
  • No yoghurt? Use any natural yoghurt, vegan yoghurt, fruity yoghurt. 
  • No self raising flour? Use 3 pots of plain flour and 1 tsp of baking powder. 
  • No vegetable oil? Use melted coconut oil or a light olive oil. 

Prep time: 15 minutes

Cook time: 45 minutes

Total time: 60 minutes

Servings: 1


2 Grapefruits

125 g Yoghurt

3 Self raising flour (pots)

1 Sugar (pot)

½ Vegetable oil (pot)

3 Eggs

1 a pinch of Salt


  1. Prepare the grapefruits: Zest, peel and segment the grapefruits making sure to work on top of a bowl to save all the grapefruit juice.
  2. Make the cake batter: Preheat the oven to 180C/160 fan/4 gas mark. Add the yoghurt to a mixing bowl. Use the yoghurt pot as a measuring tool and add the flour, sugar, salt, and oil to the mixing bowl. Then add the eggs, grapefruit juice and zest. Whisk until you have a smooth batter.
  3. Bake the grapefruit cake: Grease your cake tin, or use a silicone one and pour in your batter. Place half of the grapefruit segments on the top. Bake for 40-45 minutes, until firmed up, golden and a knife inserted in the center comes out clean. Serve with the rest of the grapefruit segments. Enjoy warm or cool.
