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!

Hiya ! Made this today had rave reviews all round. However my sponge cakes did not rise as much as yours did in video – maybe only half the height – otherwise it was light trying to work out where I may have gone wrong ????
Hi Suzanne! 🙂 So happy to hear you had rave reviews for the cake 😀
With the cake not rising as much, it could be because the egg whites were underwhipped, or the batter was folded a little too much at the end and therefore too many of the air bubbles were pushed out. It could also be the baking tin (if you used tins that were slightly larger than mine), or even checking on the cake too early as the rush of cold air in the oven can stop the cake from rising well. So many variables when it comes to making a sponge cake but hope this helped Suzanne 🙂
Hi! I haven’t made this cake yet (but I plan to this weekend) and I’m wondering what advice you have for making it in advance. I need it for Saturday. Should I bake it Friday morning/evening and then decorate it Friday or Saturday?
Thanks for the helpful recipe 🙂
Hi there! So sorry I am late in replying, but for future reference, you can totally make the sponge cakes the day before (including soaking them in the simple syrup) and store in an airtight container for the next day. Best to decorate on the day due to the whipped cream 🙂
Hope that helps and hope you enjoyed the recipe if you decided to give it a go 🙂
New to baking at 67 just retired, followed your recipe to the letter, came out perfectly, all family say best sponge cake they have ever had. One drawback, everyone wants me to bake for them lol 😂
Haha awesome Alan!! So so happy to hear you and your family loved the recipe 😀 looks like you’ve uncovered a new secret talent!
I’m wondering if I could substitute the white vinegar for apple cider vinegar, or white wine vinegar? Just to save me buying another bottle. And finally, this should bake fine as a flat cake in a 12” round tin right? I’m doing ‘pizza’ cake for my kiddo’s birthday and he’s a fan of light cakes.
Hi Helen 🙂 I think white wine vinegar should work! For a 12inch pan you may need to make double the recipe otherwise the cake will be very thin. If you’re going for a thin cake then just be sure to reduce the cooking time 🙂
Hope that helps and hope your son has a wonderful birthday!
Hi! Your recipe looks amazing and I can’t wait to try it out. I do have one question though. What do I substitute for the cornstarch if I can’t find any in my hometown?
Hi Siqr 🙂 So happy to hear you’re wanting to try the recipe! Cornstarch is a super important ingredient in this recipe in order to achieve a soft/light sponge. Another name for it is cornflour (incase this makes it easier to find). I haven’t tried any substitute myself, though something like arrowroot powder, tapioca starch or potato starch may work though I can’t provide any guarantees sorry! You could try cake flour too, though the sponge may be a bit heavier. Sorry I couldn’t be of more help Siqr – if you do decide to try it out would love to hear how it goes 🙂
I had such great success with this recipe, thank you!!! It was my first time making a sponge so I was quite nervous (even though I’m an experienced home baker). I didn’t prep as well as I should have so I had a few spot fires to put out as I went. However, I followed the instructions and the video and achieved the softest and fluffiest sponge, which didn’t taste eggy at all! The video instructions were excellent, clear and precise, supported well by the written recipe and notes. I made a tiramisu cake with those sponge layers which the family approved. Thank you Maryam! I will be coming back for more recipes and tips!
Yay! So so happy to hear you loved the recipe Elin 😀 really appreciate the wonderful feedback and hope you enjoy the other recipes just as much 🙂
