This Orange Sponge Cake is a soft, lightly citrus-flavoured sponge with a fresh orange aroma and a gentle sweetness. The flavour comes from both zest and juice, giving a natural orange taste without being sharp or heavy.

It is a calm, everyday fruit cake that suits home baking and beginner confidence. The method is clear and steady, producing a light sponge that bakes evenly and slices neatly once cooled.

Recipe Information

Difficulty: Beginner
Prep time: 15 minutes
Cooking time: 35 minutes
Total time: 50 minutes
Servings: 8 slices

Ingredients

  • 170 g plain flour

  • 2 teaspoons baking powder

  • Pinch of salt

  • 150 g caster sugar

  • Finely grated zest of 1 medium orange

  • 2 medium eggs

  • 100 ml sunflower oil

  • 100 ml fresh orange juice

  • 2 tablespoons milk

Step-by-Step Method

  1. Heat the oven to 170°C fan. Grease and line the base of a 20 cm round cake tin.

  2. In a large bowl, mix the flour, baking powder, salt, sugar, and orange zest until evenly combined and fragrant.

  3. In a jug, lightly beat the eggs with the oil, orange juice, and milk until smooth.

  4. Pour the liquid mixture into the dry ingredients.

  5. Stir gently with a wooden spoon until a smooth, pourable batter forms and no dry flour remains.

  6. Spoon the mixture into the prepared tin and level the surface lightly.

  7. Bake for 35 minutes, until lightly golden, risen, and springy in the centre.

  8. Check doneness with a skewer inserted into the middle. It should come out clean.

  9. Leave the cake in the tin for 10 minutes, then turn out onto a wire rack to cool completely.

Baking Tips

  • Zest the orange before juicing it to make the process easier.

  • Stir gently and stop as soon as the batter looks smooth to keep the sponge light.

  • The orange aroma will be noticeable when the cake is ready.

  • Allow the cake to cool fully before slicing so the crumb sets properly.

Variations

  • Orange and lemon: Replace half the orange juice with lemon juice for a brighter flavour.

  • Dairy-free: Use a plant-based milk such as oat or soy.

  • Loaf tin: Bake in a lined 900 g loaf tin for 45 to 50 minutes.

Serving Suggestions

Serve plain with tea, or dust lightly with icing sugar. This cake is also lovely with fresh fruit or a spoon of softly whipped cream.

Storage and Reheating

Store in an airtight container at room temperature for up to 3 days. Freeze slices for up to 2 months and defrost at room temperature. Warm gently if desired.
