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!

I only have an oven for 1 baking tin, can the other half of the batter be left on first?
Hi Yasmin! You can bake one cake layer first, and then the other one after the first one is done 🙂
Do you have a recipe book that I could buy please . Thanks Lynda
Hi Lynda! I don’t have a recipe book just yet but will be sure to let you all know once I get around to doing a project like that 😀 appreciate all the love and support 🙂
Hi! Quick question, if I’m refrigerating this cake to decorate the next day, should I apply the sugar syrup before putting in the fridge or wait until taking it out?
Hi Fran! You could do either option, but I would suggest putting the sugar syrup on the day before, and then leaving the cake out at room temp in an airtight container as the layers will be fine without refrigeration 🙂 enjoy!
Perfect sponge cake
Followed the recipe to T .
Thank you for the amazing recipe !
Awesome! So happy you loved the recipe Tara 😀
This was amazing! It was my first attempt at making a homemade sponge cake and it was light and airy and fluffy! I used it for a strawberry trifle for Valentine’s Day and my boys went nuts over it. I didn’t have the size pans you used and everything else I had was nonstick so I had to use my old metal 8×8 round baking pan (only one pan, I couldn’t find the second one) and the batter went almost all the way to the top. I put a pan underneath because I was almost sure it would spill over but I was ok! It took around 28 minutes to cook at 345 degrees (no fan in my oven) I will definitely make this one again!
So so happy to hear you and your boys loved the recipe Becca and that the batter didn’t overflow! Appreciate the feedback 🙂
Hi I am making a large sheet cake about 3 inches high. What do you recommend for cooking time
Hi Samantha! It’s hard to say as I haven’t tried out such a tall version of this cake myself sorry, so you may just need to play around with the cook time a bit. Perhaps check around the 30 minute mark and go from there 🙂
Hi from the UK! I wanted to ask if I could make this cake in 6″ round tins that are quite deep? Would this affect the baking time at all or the overall recipe? I don’t have any 8″ tins. Thank you
Hi Aaisha! For 6 inch pans I would recommend halving the recipe 🙂 they may bake up well as two tall cakes if you decide to do the whole recipe, I just haven’t tried it myself so can’t say for sure 🙂 enjoy!
Hello, just wondering if I can use raw sugar instead of white sugar?
Hi Lisa! 🙂 I haven’t tried this recipe with raw sugar myself, but I imagine it would affect the taste and texture of the cake slightly as raw sugar tends to have more moisture in it. With some experimenting it may work fine, but sponge cakes are very delicate and sensitive to change so I would recommend sticking to the white sugar if possible 🙂
For doubling the recipe 2x .u are given the same 8 inch pan ,does it works for all measurements the same pan size
Hi Serina! So sorry about this mistake – I need to figure out how to fix this 🙁 if doubling the recipe then you would want to use four 8 inch cake pans or two larger 10 inch cake pans 🙂 hope that helps!
Hello, I hope you’re doing well! I’m looking to make this cake for my siblings birthday cake and need to feed about 16-18 people, would doubling the recipe be enough to make 2 layers of cake in a 12×17 rectangle pan?? Also would I need to make any adjustments for it to cook in a pan that size compared to the round ones? Thank you!
Hello Serena! I’m doing well thanks and hope you are too 🙂 Doubling the recipe should work, and if you have too much batter you can use it to make a smaller cake on the side or little cupcakes too 🙂 in terms of cook time, if the cake pan is deep and the batter is about as high as it is in the original recipe (just under 1.5inches high) then the cooking time should roughly be the same, but if the tray is shallow and the cake is on the thinner side then you will need to reduce the cooking time – I’d check at about the 15 min mark to see if it’s done and then bake more if needed. Hope that helps! 🙂
Hey there from Aus! Just confirming, if using cake flour I should only use 40g not the sum total that the recipe calls for flour & cornstarch? Would you recommend adding a tiny bit of cornstarch for that extra fluffiness or completely exclude? I have both types of flour but I bought cake flour especially for this occasion (had a previous recipe chosen in imperial measurements but some reviews put me off…) so would like to use. Looking forward to baking your recipe!
Hi Rebecca! 🙂 So you would only want to substitute the all purpose flour, but also add in the additional cornstarch 🙂 so 40g cake flour and 60g cornstarch. Just keep in mind though I haven’t tried cake flour myself in this recipe so can’t say for sure that it won’t affect the structure of the cake, but I think it would work fine – if anything it will just make the cake softer meaning it won’t be able to handle heavy fillings 🙂 hope that helps!
