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!

Hi Mk,
The reviews on this are so good I want to try it myself. However, I don’t have any corn starch, would gluten free corn flour work?
Hi Angelina! 🙂 If by corn flour you mean the yellow powder (also called maize flour in some countries), then I am not too sure if that will work as I’ve never tried it myself sorry!
I hope to make this cake for Mother’s Day this weekend. Can I make the sponge on Saturday and decorate it on Sunday? If so how do I store it to stop it drying out and do I syrup it before or after storage?
Hi Urszula! 🙂 Yes you can totally do that – I would make the cake layers, add the syrup to them and then leave them in an airtight container at room temperature overnight. You can then use it the next day for decorating 🙂 enjoy!
Is the cornstarch, the gluten free one or the wheaten cornflour?
Hi Rosella! It’s the gluten free one 🙂 hope you enjoy the recipe!
Hi ur recipe looks amazing
I also bake too much cakes but I never ever use cornstarch.i can use only flour
Can u guide me
Thank you Khadijah! 🙂 Replacing some of the all purpose flour with cornstarch will help you achieve a super soft cake because cornstarch doesn’t have any gluten in it. Check out this blog post for more information on why I use cornstarch in my recipes 🙂 https://cakesbymk.com/recipe/cake-flour-substitute/
Thank you for the recipe. I have a severe allergic reaction to baking powder. I was looking for cake recipes that doesn’t taste like bread with out it. Cake with corn flour is a new idea and your recipe looks tasty. Thank you again.
You’re so welcome Sepali! Hope you enjoy the recipe 🙂
This is a really great recipe. Best light airy sponge I’ve ever made.
Yay! So happy to hear you loved the recipe Jasmine 😀
Hello! I’m wondering would this recipe work if scaled up for a large sheet cake? (e.g. 40x25cm rectangular tin)
Hi Olivia! Yes if you use the gram measurements it should work just fine! Enjoy 🙂
Hello it looks great i want to try it , can we make it in advance and freeze it , should we do simple syrup before freezing or after
Hi Moni! 🙂 I haven’t tried freezing these cake layers myself, but if they’re wrapped well (1 layer of cling wrap and 1 layer of foil) and then placed into an airtight container before freezing, then it should be fine 🙂 I would add the simple syrup after they have thawed from being in the freezer 🙂 hope that helps!
Hi, this looks like a terrific recipe, and I’m going to try it! I want to make cupcakes (and will fill either with your raspberry jam or some lemon curd I have in the fridge). How many cupcakes will this recipe make? I don’t have a good sense for how much these will rise. And should I invert the cupcakes after baking, if they don’t come up over the top of the case?
Thanks!
Hi Dina! 🙂 I haven’t tried this recipe as cupcakes myself so not too sure how they will bake up, but I imagine it would be a good idea to invert them when they’re done, and definitely check them earlier than the stated cooking time 🙂
I’m not sure the exact amount of cupcakes you would get from this recipe, but it should be more than 12 (probably around 15-17 cupcakes). Hope that helps 🙂
Hi, I made this recipe and the sponge came out amazing and really soft and delicious. I’m wondering if I can cover the cake with buttercream instead and will the structure of the cake remain okay? Than you
Hi Munazza! So happy to hear you loved the recipe 🙂 the cake layers are very light so buttercream may be a bit too heavy. If you use a ligher buttercream (like this buttercream recipe), then it may be okay, but I do feel that the bottom layer may still be squished a little 🙂
