Kinder Bueno is a very good chocolate bar, but I’ve never made a dessert with it before. So I decided to make a Kinder Bueno cake.
I’ve been enjoying turning chocolate bars into cakes recently. I’ve done a Snickers cake, a Twix cake, and now here we are…a cake inspired by Kinder Bueno.
This cake was so moist and it had an amazing flavour. If you like Kinder Bueno, you need to try this!

What makes this a Kinder Bueno cake?
So if we think of a Kinder Bueno bar, it’s essentially made up of 4 parts, you got the filling, which is a white chocolate hazelnut filling. Then there is a thin wafer layer, it’s coated in milk chocolate and then a drizzle of dark chocolate on top.
I feel like the star of the show is the white chocolate hazelnut filling though.
So for this cake I made 2 chocolate cake layers, to represent the milk chocolate. Then I made a white chocolate hazelnut filling to put in the middle of the cake.
Then after I had iced the cake, I added a dark chocolate ganache drip, to represent the dark chocolate drizzle on top of a Kinder Bueno.
The only thing missing in this cake is the wafer.
But personally I don’t love wafer inside of cakes, I feel like they end up tasting soggy after a while. But you could definitely chop up some wafers and add them to the centre of the cake if you wanted to!
The white chocolate hazelnut filling
The centre of a Kinder Bueno is essentially a white chocolate hazelnut spread…it’s like a white chocolate Nutella.
Side note I’m very confused why Nutella doesn’t sell a white chocolate version. I am in no place to tell them how to run their multi billion dollar company butttt I feel like a white chocolate version is a smart idea. I’m very confused why they don’t sell it.
Anyway I digress.
You can buy a white chocolate hazelnut spread, if you’re from the UK, Morrisons has one that is very good. BUT IT’S ALWAYS OUT OF STOCK.
I’ve only had it once, but then I never saw it again. I haven’t been able to find it, and I also haven’t found anywhere else that sells one. So instead we’re just making it.
If you can find it, you should absolutely just buy it, it will make things easier, but here’s are the ingredients you will need to make it:
- White chocolate – the white chocolate is going to add enough sweetness to this, so there is no need to add any sugar.
- Hazelnuts – it’s best to use roasted and peeled hazelnuts. I just buy them like this, so I just used them straight out of the packet.
- Salt – to enhance the flavours.
- Oil – I used vegetable oil, but any flavourless oil does work.
- Vanilla extract – for flavour.
To make it, all you need to do is process your hazelnuts in a food processor, until you get a paste, or a hazelnut butter.
Then add the melted white chocolate and the rest of the ingredients. It will be runny at first, but it will set up after a while.
It does take a few hours to set up at room temperature. It sets much better at room temperature so I recommend just waiting. But if you did want to speed up the process, you could put it in your fridge.
But again, it does set better at room temp.
Store bought white chocolate hazelnut spread VS homemade
I have to be honest, this is one of those rare things where I do think the store bought version is slightly better.
The only reason why is because the store bought version is much smoother.
I just don’t have the right equipment at home to get a super smooth nut butter from our hazelnuts. And I’m assuming most people don’t either.
So the one we make at home is not as smooth. I do like the not-smooth part, it adds a nice texture. But if we’re comparing it to store bought versions, or the one inside a Kinder Bueno, it’s not exactly the same.
But we work with what we have you know, it still tastes amazing!
The chocolate cake layers
Once we have made the hazelnut filling and have left this to set. We can make bake and leave the layers to cool.
Here are the ingredients you will need to make the cake layers:
- Cocoa powder – unsweetened cocoa powder is always best to use.
- Hot water mixed with coffee – the hot water is going to hydrate the cocoa powder, which will intensify the chocolate flavour. The coffee will intensify the flavour too.
- Oil – just like the filling, any flavourless oil will work. I used vegetable oil though.
- Buttermilk – for extra moisture.
- Eggs
- Plain flour – also known as all purpose flour.
- Sugar – I used a mixture of both brown and white sugar. The brown sugar is going to add flavour and some moisture.
- Baking soda – to make the cake rise.
- White vinegar – this is going to react with the baking soda as the cakes bake, giving them an extra lift.
Ingredient substitutions for the cake layers
There are a few ingredients that I used to make the cake batter, that I’m always getting asked if there are any substitutions for.
Let’s talk about those:
The coffee
Coffee is added to a lot of chocolate desserts. All it does is intensify the chocolate flavour; it makes it taste more chocolaty.
It won’t make your cake taste coffee flavoured at all, so if you don’t like the taste of coffee and are worried about this, you don’t need to be. All it does it intensify the flavour.
But if you wanted to leave it out, you could, the cake will still taste great.
But make sure to still add the hot water, just don’t mix the coffee into this water.
The oil
Most cakes need some kind of fat, this can either be butter or oil.
Butter adds great flavour whereas oil adds moisture.
However for chocolate cakes, I feel like the butter doesn’t do much to the flavour, since the chocolate takes over.
So instead I just use oil so I can get that extra moisture.
The buttermilk
The buttermilk is going to add moisture to the cake, and also the acidity in the buttermilk will react with baking soda, which helps the cake rise.
If you didn’t have buttermilk, the best substitute is plain natural yoghurt. I just use this most of the time to be honest.
Or instead, you could make a buttermilk substitute by mixing together 120ml of whole milk and 1/2 tablespoon lemon juice or vinegar. Leave this aside for 10 minutes, then it is ready to use.
But I do think buttermilk or plain yoghurt are the best 2 ingredients to use, so if you have these, use it!
The vinegar
The last step in making the cake batter is to mix some baking soda and vinegar together. Then mix this into the cake batter.
This is something that is typically done in red velvet cakes. Essentially, the vinegar reacts with the baking soda in the oven. This gives the cake an extra lift as it bakes, which makes it fluffier and gives it a velvety texture.
I always use white vinegar, but apple cider vinegar works great too. These 2 give the best results, but if you didn’t have either, lemon juice works too.
The Swiss meringue buttercream
I filled and covered this cake with a Swiss meringue buttercream.
I also mixed some of the hazelnut filling that we made into this. Just for extra flavour.
Of course you can use whatever icing you want, I just think Swiss meringue buttercream works best in cakes. It light and fluffy, and also not too sweet.
Here’s the recipe for it – Swiss meringue buttercream.
I didn’t include it in the recipe card below, just because if you’ve never made Swiss meringue buttercream before, it is a bit of a process.
So I’ve got a separate blog post for it, I go into a lot of detail in that post!
The dark chocolate ganache drip
I added a dark chocolate ganache drip to this cake. Again this optional, it was mainly for decoration. But it was a nice addition.
To make it, all you need is dark chocolate and double cream. You just heat these together until the chocolate has all melted and you have a smooth mixture.
If you don’t like dark chocolate NOT TO WORRY, you can make a milk chocolate one or a white chocolate one instead.
But if you are doing this, make sure to use half the amount of cream. So instead of using 100ml, use 50ml. The ganache will be too thin if you use the full amount of cream.
I make a lot of cakes, here are some other recipes I think you might also like:
Kinder Bueno Cake
Ingredients
- For the white chocolate hazelnut filling:
450g white chocolate
250g hazelnuts, roasted and peeled
1/4 teaspoon salt
80ml vegetable oil
2 teaspoons vanilla extract
- For the chocolate cake layers:
50g cocoa powder
80ml hot water mixed with 1 teaspoon instant coffee
200ml vegetable oil
120ml buttermilk
4 eggs
200g plain flour
125g granulated sugar
125g brown sugar
1 teaspoon baking soda
2 teaspoons white vinegar
- For the buttercream:
200g of the white chocolate hazelnut spread
- For the ganache drip:
100g dark chocolate
100ml double cream (if you're using milk chocolate, use 50ml of cream instead)
Directions
- Making the hazelnut filling:
- Add your chocolate into a bowl and heat this in your microwave for 30 seconds. Take this out and give it a stir. Then place it back and heat for another 30 seconds, take it out and stir again. Keep repeating this until all the chocolate has melted. Leave this aside.
- Add your hazelnuts and salt into a food processor and process until you get a paste, one that resembles peanut butter, or any nut butter. This might take some time, the hazelnuts will go through stages but you will eventually get a paste.
- Now add your oil, vanilla and melted white chocolate into this. Process until smooth.
- At this point I like to push this mixture though a sieve to get out any large lumps, then just cover and leave this to set up. This will take a few hours at room temperature, you can put it in your fridge to speed up the process but I don't like doing this, it sets much better at room temperature.
- Making the cake layers:
- Start by pre-heating your oven to 180c/350f. Also grease and line two 8 inch cake tins.
- In a large bowl, add the cocoa powder and hot water/coffee. Whisk until combined.
- Add the oil, buttermilk and eggs into this. Whisk until combined.
- Now add the flour and both sugars. Whisk just until you get a smooth batter.
- In a separate small bowl, add the baking soda then pour the vinegar over this. This mixture will start to bubble, just give it a quick mix then pour it into your cake batter. Whisk this in.
- Pour this batter into your cake tins and bake at 180c/350f for around 35-40 minutes, or until a toothpick inserted into the centre comes out clean. Once baked, leave to cool completely.
- The buttercream:
- Get your buttercream and 200g of the set hazelnut filling. Mix these together then leave this aside until you're ready to use it.
- The ganache drip:
- In a bowl, add the chocolate and cream. Heat this in your microwave for 30 seconds, take this out and give it a stir. Place it back into your microwave for 15 seconds this time, take it out and stir again.
- Keep repeating this until all the chocolate has melted and you get a smooth mixture. Leave this aside until you're ready to use it.
- Assembling:
- Once everything has been made, the hazelnut filling has thickened and the cake layers have cooled completely, you can put the cake together.
- Place one of your cake layers down onto a plate or cake board, spread some of the buttercream on top of this, then pipe a border of the buttercream around the edge of the cake. Add some of the hazelnut filling in the middle of this, then add the second layer of cake on top.
- Now you can decorate the cake however you want. I just covered it with the buttercream, let this chill for about 20 minutes, then added a ganache drip and some chopped Kinder Bueno on top.
- Now cut into it and enjoy!
