Equipment

  • Mixing bowl
  • Whisk or electric mixer
  • Non-stick baking tray (L 33cm x W 23cm x H 5cm)
  • Measuring cups & spoons
  • Zester (for orange zest)

Ingredients

Orange Cake
  • 225g butter
  • cups (438ml/350g) castor sugar
  • 4 eggs
  • 1 cup (250ml) milk
  • 1 tablespoon vanilla essence
  • 1 juice and rind of an orange
  • cups (688ml/385g) self-raising flour
Orange Whipped Cream Topping
  • 250ml cold fresh cream
  • 2-3 tbsp icing sugar (adjust to taste)
Orange Glaze Topping
  • 130g icing sugar
  • 2-3 tbsp fresh orange juice

Instructions

Orange Sheet Cake

  • Preheat your oven to 180°C. Grease and line a rectangular baking tin to prevent the cake from sticking and to make it easier to remove once baked.
  • Beat the butter and castor sugar together until the mixture becomes pale, light, and creamy. This step helps incorporate air into the batter, which contributes to a soft and fluffy cake.
  • Add the eggs one at a time, beating well after each addition. This helps keep the batter smooth and prevents it from curdling.
  • Pour in the milk and vanilla essence, then mix until the batter becomes smooth and well combined.
  • Stir in the fresh orange juice and orange rind. The rind contains natural oils that enhance the citrus flavour of the cake.
  • Sift in the self-raising flour and gently fold it into the batter until just combined. Avoid overmixing, as this can make the cake dense.
  • Pour the batter into the prepared baking tin and spread it evenly using a spatula so the cake bakes evenly.
  • Bake for around 40 minutes at 180°C, or until a skewer inserted into the centre comes out clean. Baking times may vary slightly depending on your oven.
  • Allow the cake to cool in the tin before slicing. Cooling helps the cake set properly and prevents it from crumbling when cut.

Orange Whipped Cream Topping

  • Pour the cold fresh cream and icing sugar into a mixing bowl.
  • Beat with a hand mixer or whisk until soft peaks form.
  • Spread the whipped cream over the cake when it has completely cooled.

Orange Glaze Topping

  • Add the icing sugar and fresh orange juice to a small bowl.
  • Gradually mix until a smooth glaze forms.
  • Drizzle the glaze over the cooled cake and allow it to set before slicing.

Notes

Use room temperature ingredients – Butter, eggs, and milk should be at room temperature so the batter mixes evenly and creates a lighter cake texture.
Don’t overmix the batter – Once the flour is added, mix gently until just combined to keep the cake soft and fluffy.
Use fresh orange zest – The zest contains natural oils that give the cake a stronger citrus flavor.
Cool the cake completely before adding toppings – This prevents whipped cream or glaze from melting.
Check the cake early – Ovens can vary, so start checking for doneness at about 35 minutes.
Line your baking tin with parchment paper – This makes it much easier to lift the cake out and slice neatly.
