This better than bakery chocolate sponge cake recipe is light, airy, moist and just straight up DELICIOUS! Paired with my homemade raspberry jam filling, and chocolate whipped cream, you are going to simply fall in love with this cake! This recipe is based on my original light and airy sponge cake 🙂

What is a chocolate sponge cake?
A chocolate sponge cake is basically a regular sponge cake, but with cocoa added in. It’s a light and airy cake that is made primarily from whipped egg whites. Unlike other types of cake, such as butter or oil cakes, sponge cakes do not contain much fat which contributes to it’s light texture.
Much like regular sponge cakes, chocolate sponge cakes are often used as a base for other desserts, such as layered cakes, trifle, or as a component in various 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 Victorian sponge cake (which is how I love mine!).
What makes this recipe stand out?
Much like my original sponge cake recipe, the simple reason behind this truly light and ‘better than bakery’ sponge cake is that… I don’t use that much flour!
Some flour is needed to help with the structure of the cake, however many recipes I’ve tried I feel use way too much and just end up being too heavy (almost like a regular cake). What I’ve done instead is substituted a lot of the flour with cornstarch, which helps thicken the batter without forming more gluten than we need. This results in the softest, airiest, bakery like sponge cake!
How to make chocolate sponge cake
I’ve said this before and I’ll say it again – sponge cakes can be tricky! BUT, they are totally doable. I’ve tried to provide as much detail as possible in my written recipe so that you have the best chances of success!
Begin by preheating your oven to 160 °C (320°F) with the fan on (see note 2 on recipe card if you don’t have a fan function) and line the bottom of two 8×3 inch baking tins with baking paper without greasing the bottom. Leave the sides of the cake tins ungreased and bare (do not line with baking paper). This will prevent the cakes from shrinking once they’re baked.

In a bowl combine your flour, cornstarch, baking powder, cocoa powder, instant coffee powder and salt. Mix until well combined (you do not need to sift it yet). Set aside.
In a medium sized bowl add in egg whites and white vinegar, and using a hand or stand mixer, whip on a medium high speed for 30 seconds until foamy. Gradually add in 1/3 cup of the sugar and then continue mixing for a further 2 minutes. Then turn your mixer down to low and mix for a further minute (about 4 minutes of mixing altogether). You should end up with stiff peaks (see note 3 on recipe card). Set aside.

In a large bowl add in your remaining 1/3 cup of white sugar and warm water. Mix so that the sugar is coated in the water. Add in the egg yolks and vanilla, and with a hand or stand mixer, whip on a medium high speed for 4 minutes, and then 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.
Stream the vegetable oil into the egg yolk mixture while mixing on a medium speed. Mix until well combined.

Add in half or your egg whites to your egg yolk mixture, and using a spatula gently fold together until just combined. Then sift in your dry ingredients, and gently fold through until just combined.
Finish off by adding in 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 of the air bubbles and do not overmix.


Distribute the batter into your baking tins and then tap your baking tins lightly on your counter. Then run a thin knife or toothpick through the batter to remove any large air bubbles and then bake for 25 minutes. To test whether they’re done, gently touch the tops and it should create a little indent which slowly bounces back.
Once the sponges are done, immediately tap them on the counter from a height of about 10cm, and lay them upside down (while still in their baking tins) on a wire rack to completely cool (see note 4 on recipe card).
Once cooled (about an hour later), run a thin knife around the edges to release the cakes from the cake tins, and 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 the top and that removes the dark crust on the sides and tops of the cake (see video for demonstration).

APPLY SIMPLE SYRUP: Combine sugar and hot water together for the simple syrup and mix until the sugar is completely dissolved. Using a pastry brush, generously brush the top and sides of the sponges with the simple syrup (see note 5 on recipe card).

Cake filling options
To fill my sponge cake I like to whip up a batch of my raspberry jam filling and make some chocolate whipped cream!
For the raspberry filling head to my raspberry filling recipe 🙂

For the chocolate whipped cream, in a large bowl add in the whipped cream, icing sugar, cocoa powder and vanilla. Whip until you reach stiff peaks. Be careful not to overwhip the cream.

You can decorate your sponge cake however you like 🙂 but below is how I do mine.
Place one sponge cake layer down, and cover the top with a thin layer of my raspberry jam filling.
Place strawberries on top (I like to cut mine in half and place them upside down). Cover with generous amount of whipped cream and spread it out evenly with an offset spatula or knife.
Place your next sponge cake layer on top and then cover with more whipped cream. Finish decorating with more strawberries on top. Enjoy!

Hey MK! Just wondering if it’s possible to put the batter into a single 8inch cake tin instead, as I only have one, and then cut the cake in half lengthwise after it’s done baking? Would I perhaps need to bake longer?
Hi Ann! 🙂
I haven’t tried this recipe as a single taller cake myself and my worry is that it may not rise as well (as opposed to making two separate cakes). Sponge cakes do usually work better as taller cakes though compared to butter or oil cakes, so it may be worth a try! Yes the baking time would need to be increased. Would love to hear how it goes if you decide to try it out as one tall cake 🙂
Hi I just made this cake today and it was really delicious! However, my cake deflated a bit.
Just wondering, can I double the recipe and bake in two 8 inches tin (full size), so I can make a 4 layer cake (cut cakes into half). If so, how long should I bake the cakes?
Hi Diana 🙂
So glad you loved the recipe! It’s normal for the cake layers to deflate slightly, but they should still be very soft and fluffy. Just be sure to allow the cakes to cool upside down in the cake tins and this will prevent them from shrinking too much.
I haven’t tried baking this recipe as a tall cake myself (and then torting it) so I’m not too sure how well that would work sorry! I’m not sure if the cakes will have enough structure to stay ‘tall’ after cooling, but would love to hear how it goes if you decide to try it out 🙂
Hii,
Thanks for sharing this beautiful recipe. I tried it two times. the taste is really good, but it does not come a big sponge cake as yours. it stays the same size. Please tell me what I do In this case
Hi Mirna! 🙂 So glad you loved the taste of the cake, but so sorry to hear it doesn’t seem to be rising well! This could be due to a few reasons, but the most likely reason is that the egg yolk mixture and egg whites perhaps require a bit more mixing. You want to make sure the egg whites are whipped to stiff peaks. Also, once the cakes are done baking, it’s super important to make sure they’re left upside down to cool and this will prevent them from deflating 🙂
Lastly, you may want to check that your baking powder is still active.
Hope these tips help for next time 🙂
Thank you so much for sharing this recipe. First time in my life I succeeded in making a sponge cake. And what a quality – I couldn’t believe I made such a luxurious sponge ! I layered with whipped cream (white) and tons of fresh cherries halves.
I’ll try your ther recipes soon, thank you MK.
Aww yay! So so happy to hear you loved the recipe Maggie 😀 sounds like you did an incredible job with it 🙂
Hope you enjoy the other recipes just as much 🙂
Can I use this sponge to make lamingtons?
Hi Sarah! 🙂
I haven’t tried that myself, but I don’t see why not! It is a very soft sponge so I suppose you would just need to make sure the icing that you roll the cake in is relatively thin/light so it doesn’t weigh the sponge down. Would love to hear how it goes if you decide to try it out 🙂
Hi I want to try your recipe,but is it ok if without coffee?
Hi Evangeline! 🙂 Yes you can omit the coffee if you prefer – hope you enjoy the recipe 😀
This cake was amazing! Absolute hit with everyone, they couldn’t get enough!
Aww yay! So so happy to hear everyone loved it Sandy 😀
LOVE this recipe will definetly be a go to for all my cakes. The only thing it did deflate in the oven so any tips would be great but didn’t comprise the taste. Yummy!!
Hi Jess! So happy to hear you loved the recipe :). When it comes to the sponge deflating, it could be due to a few reasons. My top tips would be to ensure that the meringue isn’t under or over whipped, and to make sure the cake tin you’re baking the sponge in isn’t greased (or non-stick) as you want the sponge to stick to the sides as it bakes and this will prevent it from deflating 🙂
hi, thank you very much for this detailed recipe :), I have a question regrading freezing the cake, can i freeze it without any change in the tase, and for how long does it keep well in the freezer or fridge?
Hi Khadija! 🙂 You’re so welcome. I haven’t tried freezing this cake myself, so I’m not 100% sure sorry, but I think if it’s wrapped well and placed in an airtight container it should be fine 🙂
I kept it in the fridge for 2 days after I wrapped it very well with plastic foil first the aluminium foil, and it worked well.
By the way, the recipe is amazing, thank you very very much for sharing it with us 🙂
That’s awesome! So happy to hear it turned out great Khadija 😀
Hi Maryam, I have just made my second attempt at this recipe. I’m improving, but my cakes did deflate somewhat each time (with the first bake, I forgot about touching the top of the cake to see if it is done, instead I swooped in with a massive skewer and popped them like a balloon (woops)!. Also, my batter is not nearly as dark brown as yours. What is the secret? Thanks for the recipe. I’m having fun refining my skills.
Hi Jane 🙂 Good on you for not giving up! Sponge cakes are one of the hardest cakes to make and takes practice so you’re doing awesome!! In terms of the cakes deflating, be sure to let them cool upside down in the cake tins if you didn’t already. It could also be because the meringue is slightly undermixed. I would also recommend using the gram measurements if you haven’t already. In terms of the colour of the cocoa, it could be the brand of cocoa. Dutch processed cocoa (which is what I used) is also slightly darker than natural cocoa, so if you’re using natural cocoa that may be the reason too. Hope these tips helped Jane! 🙂
Thank you so much gorgeous lady for sharing your delicious chocolate sponge, I made it for Father’s day and invited a neighbour in who was on his own and it went down a treat, it was soooo light! although I must say mine didn’t look as impressive as yours but I’m on my way to perfecting that and I used home made plum jam which was delish but am going to do you raspberry version next time
So so happy to hear you and your guests enjoyed the cake Carolyn! 😀
this was so delicious! I made this for my family as a 12 year old girl and it was amazing! My parents don’t like cake that is too sweet so this was great! I have been practicing my decoration skills and i was very proud of the end result. but when i took my cake out of the oven i shrunk on the sides a bit and it kinda looked sad but it was really good! if you have any recommendations for a not to sweet but delicious cake please let me know!! This was the first recipe from you and it was amazing! Any other recipes from outside this website did not taste good.
Hi Jenna! So so happy to hear you enjoyed the recipe 😀 in terms of the cake shrinking, be sure to let the cake cool upside down in the cake when you first take it out of the oven (if you didn’t do this already) as this will help prevent shrinking 🙂 and I have heaps of other cake recipes you can check out here: https://cakesbymk.com/recipe-category/cakes/ but for a less sweet cake I would recommend using a lighter frosting like this: https://cakesbymk.com/recipe/stabilized-whipped-cream-frosting/ or even a Swiss meringue buttercream: https://cakesbymk.com/recipe/stabilized-whipped-cream-frosting/
Hope that helps 🙂
You are one special person Maryam and I am so grateful that you put your lovely chocolate sponge on line, you are very talented indeed. Just one question if I may. when I bake it the texture is gorgeous but the cooked cake doesn’t stay risen like the white sponge i make, it goes flat?
Thanks so much Carolyn 😀
So while cooling, the sponge will deflate slightly and won’t be as tall as when it first comes out of the oven. It shouldn’t flatten too much though and if this is the case, it could be due to the meringue being under or over-whipped, or the batter being over-mixed (so too many of the air bubbles have been pushed out). So sorry I can’t be of more help, but those are usually the reasons that causes sponge cakes to deflate too much. I would also make sure the sponges are left upside down in the cake tins to cool to prevent shrinking too. Hope that helps for next time Carolyn 🙂
Hello Maryam
I make your sponge lots and it’s loved by all but now I want to make and oblong one in a sponge roll tin do you think that would work?
Hi Carolyn! So happy to hear you’re loving the sponge cake recipe 😀 I haven’t tried this chocolate sponge as a roll cake myself so not 100% sure that it’ll roll up well, though I think it would work okay as this is quite a flexible sponge cake. I’ll be releasing a chocolate roll cake recipe soon so keep an eye out for that 😀
