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.

I made these but they turned out like cakes but still tasty. I had to bake them for longer than 20 minutes because when I took them out of the oven they were very wobbly and thought they were not ready. How do you know when they are ready? I have clearly overtakes them.
They’re definitely over baked then. Did you use the correct size tin?
Hi!
I was just wondering if you knew the calorie count for this, as my girlfriend is having a slight cheat day on Valentine’s but I don’t want to go over the top. It would be most appreciated!
Thank you!
Hi!
I was just wondering if you knew the calorie count for the cake as my girlfriend is having a slight cheat day on Valentine’s Day but I just don’t want to over do it if it is a lot of calories! It would be most appreciated!
Thank you!
Hi Jane,
I make this recipe all the time – I love it!
Is there any way of making the cookie bars up (not cooking) a day early and storing them in some type of way before cooking?
Thanks
The cookie dough can be put in the fridge over night! x
Hi, I love this recipe and it always turns out perfect. I was wondering if or how I could make this recipe vegan? Thankyou!
You can use a vegan butter, and replace the egg with the usual sort of replacement of flaxseed/chia and water, or mashed banana etc! But then obviously kinder isn’t vegan so that would need a replacement x
Hi Jane
Can I substitute the egg in this recipe?
Yes, usual egg substitutes like flax seed, mashed banana etc work!
Hi, i used this recipe and it was amazing! i just swapped the kinder for triple chocolate chips instead.
can i ask do you have the nutritional information on this recipe?
Many Thanks!
Hey!
Do you know if your able to make the cookie dough and either keep it in the fridge or freeze it, if so, for how long?
The raw dough can be in the freezer for 48 hours, or freeze up to 3 months x
Hi Jane! Can you freeze the cookie bars after baking and if so how would you reheat? Love your recipes 🙂
Yes you can! And a quick microwave after thawing for a bit maybe!
Hey lovely sorry it’s so late. Is there anything I can substitute bicarb with? I’ve run out and it’s the MIL birthday tomorrow 😩 or am I destined for a late night supermarket run!
Thank you!!
Ideally it would be used – but you can try 1tsp baking powder instead x
Delicious!! I checked mine at 17 minutes and they were basically fully cooked, not quite gooey. So next time I know to keep an eye on them (my oven isn’t the best!).
But still so delicious, especially warmed up 🤤
Is there a reason why mine turned out cakey?:( Would love to try this recipe again any tips for it not to be cakey and more cookie like?😅
Did you use plain flour? And how did you mix it?
Hi Jane, I’m baking this tomorrow for the second time for a customer however I only have a 13 x 6 rectangular tin. Can you please assist me on timings and would the ingredients be the same amount?
A 13″x6″ is about the same volume as the 9″x9″ so the measurements are the same – I haven’t used that size tin before but I imagine it be similar!
Anything Kinder and I’m there! Absolutely loved these.
Hi Jane, would this recipie work with any chocolate instead of kinder and kinder bueno? Such as munchies, boost, or even plain choc chips or galaxy etc or would you need to change anything else if changing the chocolate?
Super excited to try!!
Hey! Yes basically its all interchangeable – some chocolates don’t work well if they have soft centres or nougat, but most do x
Turned out amazing!
Thankyou for this recipe
Hi there, I tried making these twice and I don’t know where I went wrong. I think it’s from the bicarbonate soda. Could you leave this out? They turned out cakey and there was a horrible taste, fishy like after taste. Very strange. My friend made them and they turned out gorgeous. I don’t know what I did wrong.
That sounds like something is off, or over measured! If bicarb isn’t measured correctly it can cause a problem as I have never experienced this with the cookie dough (And the dough is the same base recipe for lots of my cookies!) x
