Gooey, delicious Kinder Bueno cookie bars packed full with Kinder chocolate and Kinder Bueno pieces

Kinder Bueno bakes
Kinder Bueno recipes honestly take over my blog a little. They’re always popular, and people always want more. I’ve actually only got four Kinder Bueno related recipes on my blog so far, but they’re some of my most popular, especially my Kinder Bueno Cheesecake.
Because of how Kinder Bueno is an absolute kicker, I thought I should post another and I know you’ll love these. Cookie bars are always a hit as well, but Kinder Bueno Cookie Bars?! Utterly next level.


Kinder Bueno cookie bars
Packed full of Kinder Chocolate, and Kinder Bueno pieces, this is the sort of treat that people will ask for again and again without fail. If you don’t like Kinder chocolate, however, please see my many other cookie bar recipes I have available
- Flour – always use plain flour, you don’t want to use self raising. I also add cornflour to create a softer texture
- Raising agents – I only use bicarb in the cookie bars, you don’t want to use baking powder
- Salt – the best addition in my opinion. I use chunky sea salt, not table salt
- Butter – block butter or bakings spread works well
- Sugar – the standard cookie mix of light brown and also white granulated sugar
- Egg – one egg only, I use medium, but large will also work
- Vanilla – an added little bit of sweetness


Chocolate
So as this is a kinder bueno themed bake, I use the kinder chocolate and the kinder bueno bars. The kinder chocolate is best for the softer more chocolate chunk style part, and the kinder bueno is just kinder bueno with that iconic wafer filling.
Folding through the Kinder Chocolate is easy as its solid, but folding in the Kinder Bueno isn’t as easy because they’re quite a bit more fragile. If you’re worried, I did it a couple of times where I put the Kinder Chocolate pieces into the cookie dough first, and then the Bueno so it wasn’t quite as solid as just the dough on its own. It’s not the end of the world if they Kinder Bueno pieces break up, but if you do it by hand it’ll be a lot safer than using a mixer for this bit


Adapting the bake
If you wanted to make these into a chocolate cookie dough, rather than a ‘plain’ one, you can add in 25g of cocoa powder, but take out 50g of the plain flour. The cocoa powder dries the cookie dough out more in comparison to the flour, so you’d have a smidge less dry ingredients.
I do have Kinder Bueno cookies on my blog which are always worth a try because, yet again with Kinder, HEAVEN! Also, Kinder lovers rejoice for my other Kinder Bueno recipes such as ice cream, blondies, a cookie pie or a Kinder tart – absolutely yes please, get me a plate now!


Tips & Tricks
If you’re not careful, the chocolate that is on top or sticks out of the cookie bars can burn slightly, but if your oven is the correct temperature it should be fine. If it’s catching, you need to lower the temperature of your oven.
- These cookie bars will last for 4-5+ days at room temperature
- These will freeze for 3+ months
- You can switch to milk chocolate chips instead of kinder chocolate
- I use this 9″ square tin
I hope you love this recipe as much as I did! Enjoy! x


Kinder Bueno Cookie Bars!
Ingredients
- 275 g plain flour
- 1 tsp bicarbonate of soda
- 1/2 tsp salt
- 1 tbsp cornflour
- 115 g unsalted butter
- 55 g granulated sugar
- 135 g light brown sugar
- 1 medium egg
- 1 tsp vanilla
- 250 g Kinder chocolate (chopped)
- 170-250 g Kinder Bueno bars (chopped)
Instructions
- Preheat your oven to 190ºc/170ºc fan, and line a 9x9 inch square tin with parchment paper, and leave to the side for now.
- Whisk together the plain flour, bicarbonate of soda, salt and cornflour together in a bowl and leave to the side for now.
- Melt the unsalted butter until liquid, and add to a bowl. Add in the light brown sugar and granulated sugar and whisk the mixture together for two minutes by an electric whisk, 3 minutes by hand.
- Add in the egg and vanilla and whisk again until they're combined.
- Add in the mixed together dry ingredients and mix until a really thick cookie dough is formed.
- Add in the chopped Kinder chocolate, and chopped Kinder Bueno, and fold through. Reserve some of the Kinder chocolate for the top of the cookie bars.
- Push the mixture into the 9x9 inch tin, and add on the last few bits of Kinder goodness.
- Bake the cookie bars in the oven for 17-22 minutes. I usually do 19 minutes so they stay reasonably gooey.
- Once baked, leave in the tin for 10 minutes to cool a bit, and then remove and cool fully on the wire rack. Enjoy!
Notes
- If you're not careful, the chocolate that is on top or sticks out of the cookie bars can burn slightly, but if your oven is the correct temperature it should be fine. If it's catching, you need to lower the temperature of your oven.

Hey,
By kinder chocolate bars do you mean the small bars with the white center like these?
Many thanks,
Adam
Yep!
Hi Jane
Kind of silly question , when you say cornflour I googled it does that mean corn starch? Planning on making these tomorrow for Xmas 😳 it days on google they are same thing
Thxs
Yeah, I’m in the UK and we call it cornflour!
Can I freeze these?
Yep!
If you made these into cookies, would it still be 16 portions youd split it into and for the same time/temp in the oven?
Thanks
Hi Jane
So I’m planning on making these very soon and was just wondering is granulated sugar just normal sugar that you put in your tea? Or should I use caster sugar instead?
Many thanks
Xx
Granulated sugar is granulated sugar, caster sugar is different and smaller granules. In the supermarket it’s classed as granulated, but as to what people put in their tea it can vary I have found!! x
If you cant get granulated sugar can you use caster sugar?
I would use all brown sugar if you can, but you can for sure try the caster sugar!
My boyfriend and I were very impressed with this recipe, thanks!
So glad you liked it!!
I’m looking forward to trying these! My husband is Coeliac though; do you think it would work using gluten free flour instead? Thank you in advance!
Hey! Well, you wouldn’t be able to use Kinder Bueno, so I’m not too sure this is the best one. You MUST still use the cornflour, and they’ll probably be crumbly. I wouldn’t suggest adding in too much more kinder chocolate either as that’ll make it ‘wetter’ when baking!
Tried it yesterday, LOVE!
I wonder if I can bake this into individual cookies?
Hi jane can you use stork in this recipe and your blondie and brownie recipes? X
You can, but I generally prefer using unsalted butter!
Hi Jane, I don’t have a square 9×9 tin, I do have square/rectangular glass Pyrex dishes would I be able to use these instead to bake in the oven? Thank you!
Is the dish still 9×9″? The size is the most important bit to get it to bake right – but you could give it a go!
Hi Jane thanks for the response! I don’t think it is, I’ve found tins that are 20cm squared and 24cm square would either of these do? Thank you!
The 24cm is closest to the 9″ so maybe give that one a go!! X
How long should I re-warm in microwave at 700w?
Thank you jane
Umm – mine is 1000w and I usually do about 25 seconds?!
Hello!
These look amazing! I’m trying to find a recipe for kinder blondies as I’ve been asked to make them! Would you say this is the same thing?
Hiya! No, these are cookie bars. They are cookies in a traybake form.
These tasted amazing. Thank you for the recipe!
Absolutely gorgeous, thank you for the recipe. We used just the chocolate bars (not the Bueno) and they came out lovely. The only downside is how quickly they get eaten!
Yessss!!
Hi Jane,
I was wondering when you say Vanilla do you mean vanilla extract?
Sorry for the silly question x
Yes I do x
