Funfetti Cake!

A three-layer funfetti cake with all the colourful sprinkles, and a vanilla buttercream frosting!

Funfetti!
It’s been a while since my blog had a little bit of colour on it, and a Funfetti Cake is 100% the best way to get that going. I love a funfetti cake, but in the UK they are much harder to come by. That’s not because people don’t want them, but because most of the sprinkles in the UK are awful!
For those of you who don’t know, a funfetti cake is essentially a basic or vanilla sponge, but with LOADS of sprinkles inside to give a confetti type of effect – but it’s all edible. Funfetti cakes are very popular in America, and they always look amazing!


Sprinkles
The problem we have over here in the UK, is that a lot of sprinkles just don’t have the same colourings or additives to make the sprinkles bright enough to bake with – a lot of the colours used in the sprinkles in America are in fact banned over here, because there are just TOO many additives!
Therefore, it makes it very difficult to get the effect you want. You can buy cake mixes in the uk, such as the Pillsbury funfetti cake mix online, which is probably the easiest way to get where you want – but its a box cake mix, and I know a lot of you aren’t a massive fan of those.


The sprinkles I use…
So, the sprinkles that I use for these recipes? These glorious funfetti sprinkles! These are the only ones I have tried so far… that work! You can try any supermarket ones, and they will either just disappear completely into the sponge, or just turn green.
I realise that buying some sprinkles online just for a cake seems a bit OTT, but if you want a good funfetti cake, and you’re in the UK like me and don’t have access to be best sprinkles ever, then it is SO worth it!


The next catch, is having enough sprinkles. To get lots and lots of colour and fun in the funfetti cake you do need to use lots of sprinkles I am afraid. The sponge itself is just a classic sponge, so it’s hard to get wrong!
Supermarket sprinkles
You can of course try supermarket sprinkles, or even branded ones that you can buy in shops, but be warned that they may not work. The really tiny sprinkle balls, and the sugar strands you can buy at supermarkets tend to be the worst as they’re already so small – so they just vanish!


Quantities
The amount you put into the cake will depend on how big you want the cake to be – as I made a three layer cake as usual, I found the two pots (120g) of sprinkles perfect for the sponges – if you were going to make a smaller version of the cake, you can easily use less sprinkles though!
As I didn’t want to take the mickey with the sprinkles, I didn’t use sprinkles in the frosting – I knew I would need a lot, and you don’t even see most of the frosting as it’s on the inside of the cake, so I just sprinkled some on top!
There are notes in the recipe on how to make a smaller two layer cake, but I hope you enjoy the recipe either way! x


Funfetti Cake!
Ingredients
Sponges
- 400 g unsalted butter (room temp)
- 400 g caster sugar
- 400 g self raising flour
- 8 medium eggs
- 1 tsp vanilla extract
- 120 g funfetti sprinkles
Decoration
- 300 g unsalted butter (room temp)
- 600 g icing sugar
- 1 tsp vanilla extract
- funfetti sprinkles
Instructions
For the Cakes!
- Preheat your oven to 180ºc/160ºfan and line three 8"/20cm cake tins with parchment paper!
- Beat the unsalted butter and caster sugar together until light and fluffy.
- Add in the self raising flour, eggs and vanilla extract to the mix, and beat again until smooth.
- Pour in the Funfetti Sprinkles, and fold through with a spatula!
- Split the mixture evenly between the three tins - bake in the oven for 30-35 minutes, or until baked through! Check with a skewer (it should be clean!)
- Leave your sponges to cool in the tin for 10-15 minutes, and then on a wire rack to cool fully!
For the Decoration!
- Beat your room temperature unsalted butter for a couple of minutes to loosen it and make it lighter!
- Add in the icing sugar a bit at a time and mix in fully!
- Add in the vanilla extract, and beat again. If your mixture is really stiff (and I mean, you will not be able to pipe with it - add in 1-2tbsp of boiling water to make it easier to pipe)
- Using your favourite piping tip, pipe buttercream onto your sponges, and add each layer of cake as you go!
- Once you have piped all of the buttercream on, sprinkle the cake with some more Funfetti Sprinkles and enjoy!
Notes
- I used these funfetti sprinkles!
- I would not recommend using cheap and basic sprinkles from the supermarket (if you are in the UK at least) as they don't work!
- If you are lucky enough to live elsewhere in the world with much better sprinkles - try others!
- This cake will last for 3-4 days in a cake box!
- To make a smaller version use:
- 250g butter/sugar/flour and 5 medium eggs
- 1/2tsp vanilla, and 60g sprinkles
- Bake in the oven for 25 minutes or so!
- Use 200g butter/400g sugar for the frosting!
ENJOY!

Catherine I’m interested in a funfetti Bundt cake too. Jane please help us as your cakes are lovely. Made the rocky road Bundt cake last week and really want to try the funfetti Bundt for my daughters birthday.
Hi,
To make this dairy free……do I just change to dairy free butter block? Everything else the same?
Thank you 😊
Hi,
Do you tend to use Stork or Butter in your bakes?
Also is it best to store all cakes in the fridge over night? & then crumb coat?
Thank you
For the cakes themselves is stork, for the buttercream is unsalted block butter! x
Hi are you able to make this cake vegan and how would you do that
Hi Jane,
What piping nozzle do you use to pipe the buttercream?
Thanks
Hiya – its mentioned on the post, a jumbo round piping tip.
Hi, I’ve tried this recipe before and it came out perfect. This time I want to make it in 2x 10″ cake tins. Would it be best to double the recipe or do you know better measurements for 10″ cake tins? Thanks.
Hiya! http://www.cakebaker1.co.uk/apps-for-bakers/baking-tin-size-conversion-calculator/ This may help you!x
hiya, i’m going to make this for my nephews birthday, i was wondering how much more of the ingredients i would need to have to be able to cover the entire cake instead?
I would double the buttercream!
Hi im wanting to make this cake for my friends daughter for her birthday, how long would I have to bake it for if I used a dome shaped cake tin? She’s wanting a princess cake.
Hello! Unfortunately thats hard to advise as I would need to know the dimensions of the tin!x
Hi, the tin is 7.2 inches at the top, 2 inches at the bottom and 5.9 inches tall. It’s the PME doll cake pan if thats any help. Thank you x
Hi when it says in your notes:
‘ To make a smaller version use:
250g Butter/Sugar/Flour and 5 medium eggs
1/2tsp vanilla, and 60g sprinkles
Bake in the oven for 25 minutes or so!
Use 200g Butter/400g sugar for the frosting!’
Would this be for 3x 6inch tins?
Thanks
Hii! Thats for two, 8inch tins!x
Hi Jane this recipe is great and has been brilliant the past times I have used it! I was just wondering if I was to bake it into 6 inch tins and wanted 4 layers how would I change the quantities. Thank you
Hello! I would use the recipe as it is, but baking times will change!x
Hi Jane,
I love your recipes! This is my first time trying the funfetti cake. I want to make a 9″ two layer version of it. Do you think it would be ok to keep all the ingredients the same or would the layers be too thick? If so, what would you recommend instead?
Thanks!
For a 2x 9″ cake I would use the same! Baking time will increase but not sure how long x
I’m excited to try this recipe. My daughter absolutely loves jam in her cakes though could I spread a layer of jam between each layer of sponge and buttercream please? Or would you advise not to? Xxxx
Hiya, yes of course!xx
