What You’ll Need
For the Sponge Cake:
| Ingredient | Amount | Notes |
|---|---|---|
| Large eggs | 6 | Room temperature, separated |
| Caster sugar | ¾ cup | Superfine sugar works best |
| Self-raising flour | 1 cup | Sift twice for lightness |
| Cornstarch | 2 tablespoons | Creates extra tender texture |
| Vanilla extract | 1 teaspoon | Pure extract preferred |
| Hot water | 2 tablespoons | Helps create steam for lift |
Essential Equipment:
- Electric mixer with whisk attachment
- Large mixing bowls (2)
- Fine-mesh sieve
- Rubber spatula for folding
- 8-inch round cake pan
Substitution Options:
- Self-raising flour → All-purpose flour (1 cup) + baking powder (1½ teaspoons)
- Caster sugar → Regular granulated sugar (pulse in food processor until fine)
- Cornstarch → Additional 2 tablespoons flour (slightly denser result)
Step-by-Step Directions
- Prepare your workspace. Preheat oven to 350°F (175°C). Grease an 8-inch round cake pan and line the bottom with parchment paper. Do not grease the sides—the batter needs to cling for proper rise.
- Separate eggs carefully. Crack eggs one at a time, separating whites from yolks into two large, spotlessly clean bowls. Even a tiny bit of yolk in the whites will prevent proper whipping.
Critical Tip: Use eggs at room temperature—they whip to greater volume. Cold eggs? Place whole eggs in warm water for 10 minutes.
- Whip egg yolks and sugar. Add half the sugar (6 tablespoons) to egg yolks. Beat with electric mixer for 3-4 minutes until mixture is pale, thick, and falls in ribbons when lifted. Add vanilla extract and beat briefly to combine.
- Prepare dry ingredients. Sift flour and cornstarch together twice through a fine-mesh sieve. This double-sifting creates incredibly light flour that won’t weigh down your batter.
- Whip egg whites to perfection. Using clean beaters, whip egg whites until foamy, then gradually add remaining sugar. Continue beating until stiff, glossy peaks form—about 4-5 minutes. Peaks should stand straight when beaters are lifted.
Game-Changer: Properly whipped whites are the secret to sponge cake success. Under-whipped = dense cake. Over-whipped = grainy, collapsed cake.
- Fold with gentle precision. Add ⅓ of the egg whites to the yolk mixture and fold gently with a rubber spatula using a cutting and turning motion. Add half the sifted flour, fold carefully, then alternate remaining whites and flour, ending with flour.
- Add hot water magic. Drizzle hot water around the edge of the bowl and fold in with just 2-3 gentle strokes. The hot water creates steam that helps the cake rise beautifully.
- Bake immediately. Pour batter into prepared pan and gently smooth the top. Bake for 25-30 minutes until golden brown and the cake springs back when lightly touched. Do not open oven door for first 20 minutes.
Crucial: Sponge cake must go into the oven immediately after mixing. Any delay causes the air bubbles to deflate.
- Cool with care. Let cake cool in pan for 5 minutes, then turn out onto a wire rack. Cool completely before filling or frosting—warm sponge tears easily.

Expert Tips for Success
Technique Mastery:
- Folding method: Cut down through center, sweep across bottom, up the side, and fold over top—never stir in circles
- Testing doneness: Cake should spring back when touched and just start pulling from pan sides
- Even baking: Rotate pan halfway through baking if your oven has hot spots
Storage & Make-Ahead:
- Best served fresh: Sponge cake is at its peak within 24 hours of baking
- Short-term storage: Cover with clean tea towel for up to 2 days—plastic wrap makes it soggy
- Freezing: Wrap unfilled cake tightly and freeze up to 1 month
Flavor Variations:
- Lemon sponge: Add zest of 1 lemon to egg yolk mixture
- Chocolate sponge: Replace 2 tablespoons flour with cocoa powder
- Orange sponge: Add orange zest and replace vanilla with orange extract
Professional Secret: For extra height, use a 7-inch pan instead of 8-inch—the batter climbs higher for more dramatic presentation.
Troubleshooting Success:
- Dense cake: Usually from over-mixing or deflated egg whites
- Sunken center: Oven temperature too high or door opened too early
- Tough texture: Over-mixed batter or expired baking powder
Common Questions
Why did my sponge cake turn out flat and dense?
The most common cause is inadequately whipped egg whites or over-mixing when folding. Egg whites should form stiff peaks that stand straight, and folding should be gentle with minimal strokes. Also ensure your bowl and beaters are completely clean—any grease prevents proper whipping.
Can I make this sponge cake ahead of time?
Sponge cake is best enjoyed fresh, but you can bake it a day ahead. Store covered with a clean tea towel (not plastic) at room temperature. If you need to keep it longer, freeze the unfilled cake wrapped tightly—it actually freezes beautifully and thaws to perfect texture.
What’s the difference between sponge cake and regular cake?
Traditional sponge cake contains no butter or oil—its light texture comes entirely from whipped eggs. This makes it lower in fat but requires more precise technique. The result is an incredibly light, airy cake that’s perfect for soaking up syrups and creams.
My egg whites won’t whip properly—what went wrong?
This usually happens when there’s fat present (yolk traces, greasy bowl, or old eggs). Start with completely clean equipment, room temperature eggs, and fresh eggs if possible. Even a tiny amount of yolk will prevent whites from whipping to full volume.
Can I double this recipe for a larger cake?
Yes, but use two separate 8-inch pans rather than one large pan—sponge cake needs proper support to rise correctly. You can also make two batches if your mixer isn’t large enough to handle doubled quantities effectively.

This fluffy sponge cake recipe is truly a testament to the magic that happens when simple ingredients meet proper technique. While it requires a bit more attention than a basic butter cake, the results are absolutely spectacular—a cake so light and airy it seems to defy gravity.
