What Is a Sponge Cake?
A sponge cake is a light and airy cake made primarily from whipped egg whites. Unlike other types of cake, such as butter or oil cakes (like my vanilla and red velvet cake), sponge cakes do not contain much fat, which is what helps give them their light and airy texture.
Sponge cakes are often used as a base for other desserts like layered cakes, trifles, or French-style pastries. It can also be served on its own, dusted with powdered sugar, or paired with fresh fruit and whipped cream like a classic Victoria sponge, which is how I love mine!

My Secret to the Perfect Sponge Cake
I’ve made A LOT of sponge cakes over the years, and after plenty of testing and tweaking, I found that one of the biggest secrets to getting the perfect texture is actually cornstarch!
I wanted a sponge that was incredibly light and airy without being too heavy or dense, so I tested this recipe over and over again, adjusting the amount of cornstarch each time. It took quite a few trials to find the right balance because too little cornstarch and the cake wasn’t quite as light as I wanted, while too much changed the texture in a way I didn’t love.
After all those adjustments, I finally landed on the amount that gives this cake its soft, delicate, cloud-like crumb. The cornstarch helps thicken the batter without developing as much gluten as flour, which helps give you that light and airy texture we’re looking for in a sponge cake.

How to make Sponge Cake
Now I’m not going to sugar coat it, sponge cakes are a little more challenging to master than regular cakes! BUT, if you carefully follow the steps below, you should end up with the perfect sponge 🙂
Begin by preheating your oven to 320°F (160°C) with the convection fan on (see recipe card for instructions if using a conventional oven). Line the bottoms of two 8 × 3-inch cake pans with parchment paper, but do not grease the bottoms. Leave the sides of the cake pans ungreased and bare (do not line with parchment paper). This will prevent the cakes from shrinking once they’re baked.
In a medium bowl, combine flour, cornstarch, baking powder and salt. Mix until well combined (you do not need to sift it yet). Set aside.
In another medium bowl, add the egg whites and white vinegar. Using a hand or stand mixer, whip on medium-high speed for 30 seconds, until foamy. Gradually add ⅓ cup of the sugar, then continue mixing for a further 2 minutes. Turn your mixer down to low and mix for another minute (about 4 minutes of mixing altogether). You should end up with stiff peaks. Set aside.
In a large bowl, add the remaining ⅓ cup of white sugar and the warm water. Mix until the sugar is coated in the water. Add the egg yolks and vanilla, then use a hand or stand mixer to whip on medium-high speed for 4 minutes. Turn the mixer down to low and mix for a further minute (5 minutes of mixing altogether). Your mixture should now be thick, and you should be able to create ribbons with it when you lift it up with a spoon.
Slowly stream the vegetable oil into the egg yolk mixture while mixing on medium speed. Mix until well combined.
Add half of the egg whites to the egg yolk mixture and gently fold together with a spatula until just combined.
Sift in the dry ingredients and gently fold through until just combined.
Finish by adding the remaining egg whites and gently fold until just combined. You can use your spatula to break up any large chunks of unmixed egg whites, but try not to push out too many air bubbles. Be careful not to overmix.
Distribute the batter evenly between your cake pans, then lightly tap the pans on your counter. Run a thin knife or toothpick through the batter to remove any large air bubbles. Bake for 25 minutes. To check whether they’re done, gently touch the tops. They should create a little indent that slowly bounces back.
Once the sponges are done, immediately tap the pans on the counter from a height of about 10 cm. Then, while the sponges are still in their pans, turn them upside down onto a wire rack and leave them to cool completely.
Once cooled (about an hour later), run a thin knife around the edges to release the cakes from the pans, then turn them out onto a wire rack.
To make my cake layers look nice and neat, I gently rub my fingers around the edges and tops to remove the dark crust (see video for demonstration). I find that the dark crust on sponge cakes can also contain a slight eggy aftertaste, which is why I prefer to remove it.
APPLY SIMPLE SYRUP: Combine the sugar and hot water for the simple syrup, mixing until the sugar has completely dissolved. Using a pastry brush, generously brush the tops and sides of the sponges with the simple syrup (see note 5). I use about ¾ of the simple syrup mixture in total.
How to Decorate a Sponge Cake
You can decorate your sponge cake however you like 🙂 but I like to fill mine with raspberry filling, strawberries and cream.
Place one sponge cake layer on your serving plate and cover the top with a thin layer of my raspberry jam filling.
Place the strawberries on top (I like to cut mine in half and place them upside down). Cover with a generous amount of whipped cream and spread it out evenly with an offset spatula or knife.
Place the next sponge cake layer on top and cover with more whipped cream. Finish decorating with more strawberries on top. Enjoy!
How to Store Sponge Cake
If your sponge cake layers haven’t been filled or decorated, wrap them tightly in plastic wrap and store them in an airtight container at room temperature for up to 2 days.
If your sponge cake has been filled with whipped cream, jam, or fresh fruit, store it in an airtight container in the refrigerator for up to 2–3 days. Allow it to come to room temperature before serving.
Frequently Asked Questions
Why did my sponge cake deflate after baking?
Some slight deflation is normal, but if your sponge cake collapses significantly, it could be due to overmixing the batter, not whipping your egg whites enough, or removing too much air when folding everything together. I also recommend turning your cake pans upside down immediately after baking and allowing the cakes to cool completely while still in the pans. This helps prevent them from collapsing as they cool.
Why do I need to cool the sponge cakes upside down?
This is a really important step! Sponge cakes are incredibly light and airy, which means they can easily shrink or deflate as they cool. By turning the pans upside down while the cakes are still inside, the cakes stay suspended and are less likely to collapse.
Can I use cake flour instead of all-purpose flour?
I haven’t tested this recipe with cake flour, so I recommend sticking to the recipe as written. There is a very careful balance between the amount of all-purpose flour and cornstarch in this recipe. We need enough gluten development to give the cake structure while still keeping that light, airy, delicate texture. Changing the flour could affect this balance and the final result!
Why do I need to whip the egg whites and egg yolks separately?
Whipping the egg whites separately helps incorporate lots of air into the batter, which gives the sponge cake its light and fluffy texture. The egg yolks are also whipped separately to create a thick, airy mixture. Gently folding everything together helps keep as much of that air in the batter as possible.
Can I make this sponge cake ahead of time?
Absolutely! You can bake the sponge cake layers a day ahead of time. Once completely cooled, wrap them tightly in plastic wrap and store them in an airtight container at room temperature. I recommend adding the simple syrup and decorating the cake closer to when you plan to serve it.
Can I use this sponge cake for a Victoria sponge cake?
Absolutely! This is actually one of my favorite ways to enjoy it. Simply layer the sponge cakes with raspberry jam or your favorite fruit filling and whipped cream. You can also add fresh strawberries for an extra delicious touch!

Would cornflour instead of cornstarch make a difference. Can’t find cornstarch anywhere 😕
Lovely recipe !!
Hi Emmie! 😊 Thank you so much! And yes, cornflour is the same as cornstarch in this recipe, so you can use it as a direct substitute. Just make sure you’re using the fine white powder that’s commonly used to thicken soups and sauces, not the yellow cornmeal or maize flour 🙂
How would this recipe need to be changed to accomodate 2x 6″ cake tins so that each cake is not too thin. Thanks 🙂
Hi Amaryllis! 😊 I’d recommend making half the recipe and dividing the batter between two 6-inch cake tins. This should give you cakes that are roughly the same thickness as the original recipe. The baking time may be slightly shorter, so I’d recommend keeping an eye on them and checking they’re fully baked before removing them from the oven 🙂
Hi, is it possible to double this recipe if I make it in a 10×3 pan? And do I have to double the baking time as well? Thanks!
Hi Andrea! 😊 One batch of this recipe should be enough for a single 10-inch pan, so you don’t need to double it unless you’re making two cakes.
You won’t need to double the baking time either. It should be roughly similar to the original baking time, although it may take a little longer. I haven’t personally tested it in a 10-inch pan, so I can’t give you an exact baking time. I’d recommend keeping an eye on it towards the end and checking that it’s fully baked before removing it from the oven 🙂
Can I use this for a tiramisu?
Hi Mila! 😊 Yes, absolutely! This sponge should work well for a tiramisu, as long as the cream filling isn’t too heavy. It’s a lovely light and airy cake, so I’d recommend pairing it with a light mascarpone cream. I hope you enjoy it! 🙂
Hi, I know usually sponge cakes work best with whipped cream icing instead of buttercream, but my client has asked for buttercream on top of sponge cake. Does this recipe work okay with swiss meringue buttercream or do you think it’ll be too heavy?
Hi Linda! 😊 I would personally recommend sticking with a lighter frosting for this sponge cake. Swiss meringue buttercream is lovely, but I think it may be a little too heavy for the delicate sponge and could weigh down the layers 🙂
The recipe was really good however I forgot to tilt my cake upside down due to which it shrinked but thats on me great recipe love it
Thanks Mehar! So glad you loved the recipe 🙂
Great footnotes, first time ive been able to make an amazing fluffy cake
Thanks Riri! So glad you enjoyed the recipe 😀
Hi, I have been following you for years. I tried this recipe and it came out great.
Also, I was wondering if you have vegan recipe for this cake? It is so light and airy, would love to try a vegan one. I was thinking of using aquafaba but not sure what to substitute for egg yolk.
Hi Shakheela! 😊 Thank you so much for following along all these years! I’m so happy to hear the sponge cake turned out great for you! ❤️
I haven’t personally tested a vegan version of this recipe, so I’m not sure what the best substitute for the egg yolks would be. Aquafaba could be an interesting option for replacing the egg whites, but the yolks also play an important role in the cake’s structure and texture. If you decide to experiment please do let me know how it goes 😀
Hi
I don’t have two round shape 8 inch tins .Is it ok to use two 8 inch square tins for the recipe .
Hi Vani! 😊 Yes, you can use two 8-inch square tins instead as they’re similar in size to the original recipe. You’ll just need to slightly reduce the baking time, perhaps by a minute or two. I’d recommend keeping an eye on the cakes and checking that they’re fully baked before removing them from the oven to ensure they don’t deflate too much. Enjoy 🙂
Could you use this recipe to make cupcakes?
Hi Sarah! 😊 I haven’t personally tried this recipe as cupcakes, but I think it should work just fine! You’ll just need to reduce the baking time. I’m not sure exactly how long they’ll take, but I’d recommend checking them around the 12-minute mark and baking for a little longer if needed, until they’re fully baked 🙂
