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!

Like eating a cloud!! I made it a couple of times now, it came out perfect both times. I’m never going to use any other sponge cake recipes and will try some of your other recipes when I find the time 🙂
Thank you!!
Aww yay! So glad you loved the sponge cake Lorenza 😀 really appreciate the wonderful feedback 🙂
What adjustments need I make for high-altitude? I live in Albuquerque, New Mexico and elevation is roughly 5300 ft.
Hi Scott! 🙂 Unfortunately I am not too familiar with high altitude baking so I’m not too sure sorry. A quick google search tells me that reducing the leavening agents and increasing the baking temp slightly seems to help? Sorry I couldn’t be of more help!
hello! can this recipe be used for cake decorating with buttercream? will it hold up just fine? thanks in advance!
Hi Mathilde! 🙂 Unfortunately these cake layers will be too soft for buttercream and it’s likely to weigh the sponges down, unless the layer of buttercream is very thin 🙂
For a sturdier vanilla flavored cake, check out my vanilla cake recipe: https://cakesbymk.com/recipe/soft-vanilla-cake/
Hello, can I freeze the cakes so I can use them another time?
Hi Jasmine! I haven’t tried freezing these sponge cake layers myself so I’m really not too sure sorry! I think it would be fine though, you just want to make sure the cake layers are wrapped twice in cling wrap and placed into an airtight container before freezing 🙂
Brilliant recipe thank you so uch for sharing! I’ve never successfully created a sponge cake until yesterday following your recipe- and it’s delicious! I have two questions if you don’t mind:
1. Can I replace the all purpose flour with a gluten free all purpose flour to make this GF?
2. I have two 22.5 x 9cm cake pans. Would I double the recipe (using your x2 card) and cook lower and longer? Thank you so much
Yay! So glad to hear you loved the recipe Kylie 😀
I haven’t tried this recipe with gluten free flour myself, but if the type you use is intended to act as a 1:1 substitute with all purpose flour then it should be okay 🙂
With the cake pans, they’re almost 9 inches so a little bigger than the ones I use, but 2x the recipe may be too much. I would recommend making 1.5x the recipe if you’re comfortable with making the necessary calculations 🙂 otherwise you can make 2x the recipe and have taller sponges that you could torte and make a 4 layer cake with slightly thinner sponge cake layers. Temp will be the same, but cook time may be a bit longer if making 2x the recipe. If making 1.5x the recipe, the cook time should roughly be the same 🙂
Hope that helps Kylie!
Indeed the best sponge. The moment I see your ingredients I know this is going to rock. I made it but I wanted less eggy sponge and made the adjustments and it work just as well. Reduced the sugar by 50% too as my country like less sweet so it’s perfect to balance up the sweetness of the fillings. You changed the game of sponge cake altogether MK!! You made it so easy to get an amazing cake . I experimented with an almost similar recipe in the past which I tweaked but was confined to the “cake flour game”, this corn flour ratio rock . You rock
Thank you so much for the wonderful feedback 😀 so glad to hear you loved the sponge and that it still came out great with the adjustments! Yes cornflour really is a game changer when it comes to sponge cakes 😀
How long does this cake last for in the fridge please
Hi Donna! 🙂 This cake is best consumed within about three days (and make sure to store in an airtight container to prevent it from drying out). Hope you enjoy the recipe 🙂
Assalamu alaykum
What will be the measurements if i use 6 eggs?
Please reply,
Wassalaam Nadia! If using 6 eggs you would be making 1.5x the recipe, so you’ll increase all the other ingredients by 1.5 as well 🙂
Just be sure to distribute the batter into three 8 inch cake tins or two slightly larger cake tins 🙂
Hope you enjoy the recipe!
Hello! I’m wanting to add lemon to this recipe! How much should I add? Would you recommend lemon juice or extract?
Hi Katie! 🙂 I haven’t tried adding lemon to this recipe myself and acidity usually does have an impact on the batter so there may be other adjustments required. You could try by starting with a tablespoon or so of lemon juice and see how that goes 🙂
Alternatively, a smaller amount of lemon extract could work well as well and may impact the batter less, though personally I prefer to use fresh lemon juice taste wise 🙂
Hi Mk! Your recipes are so good! I’m planning to make this cake for a friend’s birthday. Can I make the sponge cake in advance like 2 days before frosting it? And how do I store it? Thank you for your response. 😊
Hi Katherine! So so happy to hear you’re loving the recipes 😀
I would recommend making the sponge cake the day before (2 days in advance may be a little long), and I would soak them in the simple syrup and then place them into an airtight container at room temperature until you’re ready to use them 🙂
Hope that helps Katherine and hope your friend has a wonderful birthday 🙂
