Unlike butter-heavy cakes, a traditional sponge cake relies on whipped eggs for structure and lift.

When done correctly, the result is a cake that is fluffy, tender, and subtly infused with orange zest and juice.

This version focuses on technique to ensure the cake stays moist, addressing the most common issue people face with sponge cakes: dryness.

Ingredients With Substitutions

Eggs
These are essential for structure and lift. There is no true substitute if you want a classic sponge texture.

White sugar
Can be reduced slightly if you prefer a less sweet cake. Fine caster sugar works best.

Orange zest
Fresh zest provides the strongest orange flavor. Lemon zest can be used for variation.

All-purpose flour
Cake flour can be used for an even softer crumb.

Baking powder
Helps stabilize the rise. Do not omit.

Orange juice
Freshly squeezed orange juice gives the best flavor. Mandarin or clementine juice also works well.

Optional moisture boost
Add one to two tablespoons of neutral oil or additional orange juice if you prefer a slightly richer, moister crumb.

Step-by-Step Instructions

1. Preheat the oven to 325°F and lightly grease and flour a 9-inch round cake pan.
2. Separate the eggs while cold, then allow both yolks and whites to come to room temperature.

3. Beat the egg yolks with sugar and orange zest until pale, thick, and fluffy.

4. In a separate bowl, whisk together flour and baking powder.

5. Alternately add the flour mixture and orange juice to the egg yolk mixture, mixing gently until smooth.

6. In a clean bowl with clean beaters, beat egg whites until stiff peaks form.

7. Gently fold the egg whites into the batter in batches, being careful not to deflate the mixture.

8. Pour the batter into the prepared pan and smooth the top.

9. Bake for 35 to 45 minutes, checking early, until a toothpick inserted in the center comes out clean.

10. Cool the cake in the pan for 10 minutes, then remove and cool completely on a rack.

How to Serve and Store

Serve the orange sponge cake plain, dusted lightly with powdered sugar, or topped with fresh whipped cream and berries. It also works beautifully as a layered cake filled with cream, fruit, or citrus glaze.

Storage
At room temperature, store the cake in an airtight container for up to 2 days.
In the refrigerator, it will keep for up to 4 days.
To freeze, wrap tightly and freeze for up to 2 months. Thaw at room temperature before serving.

Expert Tips for Success

• Always bring eggs to room temperature before whipping for maximum volume.
• Beat egg whites to stiff peaks but stop as soon as they hold their shape. Overbeating causes dryness.
• Fold egg whites gently into the batter using a light hand to preserve air.
• Check doneness early. Overbaking is the number one reason sponge cakes turn dry.
• For extra moisture, brush the cake lightly with warm orange juice or orange syrup after baking.
