This chocolate birthday cake is simple to make, tastes delicious and is perfect for decorating for a special celebration.
I hate getting questions that I can’t give a helpful answer to, so over the past few weeks I’ve been a busy bee trying to perfect my chocolate cake recipe. Now this couldn’t be just any old chocolate cake, it had to be perfect for a birthday which meant it…
I get a lot of comments on my all-in-one vanilla sponge birthday cake and the ones that always makes me smile the most are when people say that they never bake and the simplicity of the recipe has given them the confidence to do more in future. I wanted this chocolate cake to be that simple to make… a cake even the novice-est of cooks can make.
This cake is so simple… chuck it all in and mix it up. The only piece of culinary skill you need is a bit of grating!
2) Must be suitable for decorating
When I make birthday cakes for my boys I love to go to town on the decoration (you can see some on my cakes in my cake gallery). In order for the cake to work as a decorated cake it can’t dome too much on top or sink in the middle and it must be sturdy enough to be carved into various shapes for decorating without crumbling.
3) Be chocolatey
This is actually the big reason I’ve not been able to recommend chocolate cake recipes until now. All the cakes I’d made in the past with the right texture (see point 2) used just cocoa powder and they simply weren’t chocolatey enough. To give this cake some extra chocolate-iness it includes lots of actual chocolate grated into the cake mix alongside the cocoa powder.
Photographing this cake caused a lot of confusion in my house as I decided it needed to be decorated just like a birthday cake with lots of colourful fondant. Josh (who’s 3) kept asking whose birthday it was and then started getting all excited about Father Christmas coming (because apparently, he delivers presents for birthdays too). I probably didn’t help matters by deciding to light the candles – a completely unnecessary step as I really only wanted to photograph the inside of the cake after they’d been blown out – we had fun doing it together though 🙂
Chocolate Birthday Cake
INGREDIENTS
- 200 g self-raising flour
- 40 g cocoa powder
- 230 g caster sugar
- 4 large eggs
- 230 g soft margarine - you can also use softened unsalted butter too
- ¼ tsp vanilla extract
- 100 g milk chocolate - choose something from the baking aisle in the supermarket as it will cope well with the heat in the oven without going grainy.
- 2 tsp milk
INSTRUCTIONS
- Pre-heat your oven to 160ºC/140ºC fan.
- Line your tins (2x 20cm sandwich tins) with liners or greaseproof paper.
- Grate the milk chocolate (100g).
- Put all of the ingredients into a large bowl (200g self-raising flour, 40g cocoa powder, 230g caster sugar, 4 large eggs, 230g soft margarine, ¼ tsp vanilla extract, 2 tsp milk and the grated chocolate) mix on a low speed until fully combined.
- Divide the mixture evenly between the two tins and spread it out so it’s pretty even (it doesn’t have to be perfect as it’ll even out in the oven, but roughly flat is good).
- Put the tins in the oven and cook for 30 minutes. After 30 minutes put a skewer in the middle and check if it comes out clean. If it does it’s done, if not pop it back in for a couple more minutes and check again.
- Once cooked, remove the cakes from the oven and leave them to cool in the tins for 10 minutes.
- After 10 minutes, remove the cakes from their tins and pop them onto a wire rack to cool completely before decorating.

What’s the best sort of fondant to use?
Charlotte Oates says
I tend to but whatever I can get hold of. Usually Tesco own brand. I’ve also used Lidl and Dr Oetker.
Charlie says
Hello, I’ve just made this cake for my sons 5th birthday and I have to say it tasted amazing! I covered it with fondant and cut out some batman decorations and he absolutely loved it. Thank you for the recipe.
Rosie May says
Hi Charlotte, I’ve made this recipe quite a few times now as it’s so lovely, I was just wondering is it ok to freeze ? If so should i wrap it in cling film and foil ? Many Thanks for all your yummy recipes x
Charlotte Oates says
Yes, it freezes well.

Hi, I wanna make a fondant cake for my daughter’s birthday, for the first time! How many days ahead of time can I make this cake? And if done, how do I store it? Should it be covered with cling wrap or foil?
What if cake starts to break off?
Thanks I’m advance!
Charlotte Oates says
I usually make mine a couple of days before and then they’re good to eat for another 5 days.
Before the cake is covered in fondant, make sure it is stored in an airtight container. Once you have added the fondant there is no need for this (as the fondant protects the sponge). However, make sure you keep it covered to protect it from any dust.

Hi, i made this cake recently and it was absolutely delicious! Thanks for such a great recipe. However, the middle sunk a little after cooling. Was this because I used one deep tin to bake the cake instead of splitting the mixture?
Charlotte Oates says
I suspect that’s what it is. I try to keep my cakes as light and fluffy and a can, but that means they don’t have quite as strong a structure as some other cakes. This is fine in sandwich tins, but can sometimes results in the cake dipping a little after baking if you use a deeper tin.
Sarah says
Hi I made this cake for a birthday and the it was delicious. However, the middle sunk a little after cooling. Was this because i put all the batter in one deep tin?
Jennifer says
Forgive me if you’ve mentioned this somewhere. But if I want to cover this cake with fondant, how much/how many packets do I need please?
Charlotte Oates says
I have a calculator where you pop in your cake dimensions and it’ll tell you how much you need.

Hi Charlotte, hoping to try out this recipe for my daughter’s birthday, she’ll be 5 next weekend.. I’m going to use your chocolate buttercream as a filling but how much should I use to coat the cake if I want to use fondant over it and decorate with some caketoppers? Should I keep it to a thin layer? Or do you have any tips? I’m always nervous at this part!! Thanks in advance, can’t wait to try it 🙂
Charlotte Oates says
I would add a generous layer in the middle and a thin layer around the outside. The layer on the outside is just to help the fondant to stick and to help you get it nice and smooth. If you make it too thick in can squidge out of the bottom as you lay the fondant on top (especially in this warmer weather we’re having at the moment). Give the warm weather, I’f recommend chilling the cake for a while after adding the buttercream to allow it to firm up a bit before adding the fondant. Don’t panic if it does squidge out. Carefully wipe it away with a dry pieve of kitchen towel and you should be fine.
Laura J says
Thanks so much for the reply!

I love this recipe. I just made my 2nd cake this week. Birthday then nursery graduation. My daughter has a milk allergy so easy to use dairy free alternatives. Instead of grated choc I used 50g of dairy free buttons. I made the cake Thurs evening and buy Sunday morning it was still fresh as my daughter and I finished the last slice. Such a delicious cake and lovely chocolate taste.
Debbie Howe says
Hi. I am going to make the chocolate cake. I noticed that you use plain flour instead of self raising. Which one is the best for raising.
Many thanks
Charlotte Oates says
You can use either. If you use self-raising flour there’s no need to add any baking powder. If you use plain then you need the baking powder listed in the recipe. You might find this post interesting to see the difference between the two.
