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

Prep Time: 10 minutes
Cook Time: 20 minutes
Total Time: 30 minutes
Servings: 16 Pieces
Author: Jane's Patisserie

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 use this 9" square tin

    I haven’t any unsalted butter. Would normal butter still work?
    They look delicious can’t wait to bake them!

    • Jane's Patisserie on April 5, 2020 at 4:11 pm

      I’m not sure what you mean by normal butter.. but it should be fine for these.

      Just a question could I use muscovado sugar instead of the brown sugar.



    • Jane's Patisserie on April 4, 2020 at 4:20 pm

      Yes you can!

    Oh my word, just made these and they are awesome! I swear by all your recipes they are always reliable and I don’t need to test bake anything as it always turns out perfect. Thank you so much 🙂

    • Jane's Patisserie on March 11, 2020 at 8:38 pm

      Ahh that’s so lovely! Thank you so much!! x

    Hi just wondered what the texture inside is meant to be like, just baked these and the outside is crumbly and crispy and then the inside is very wet

    • Jane's Patisserie on March 11, 2020 at 9:20 am

      They’re meant to be cookie-like – a slightly crunchier outside with a gooey middle!

    I don’t know what went wrong… why have mine turned out to be a sponge rather than a cookie??

    • Jane's Patisserie on March 11, 2020 at 9:20 am

      As the recipe has the ingredient it has, something potentially was measured incorrectly or mixed incorrectly as I have honestly never experienced that with a cookie mix!

      Mine turned out sponge like to however they still taste great



  6. Joanna on March 9, 2020 at 11:01 am

    Hi Jane,

    Is it possible to use other chocolate for this recipe e.g. galaxy chocolate, in the same measurements?

    Love all your recipes!

    I had the same problem that others seemed to have that the mix was really dry and crumbley, so I just added a splash of milk so it would come together and it seemed to work! I also found the amount of kinder Bueno bars too much, I used 170g but guess this is just personal preference 🙂 but amount of kinder chocolate was spot on 🙂

    • Jane's Patisserie on February 12, 2020 at 1:54 am

      As I’ve said before, the dryness of the cookie dough does not affect the bake.



  8. Ericka on January 31, 2020 at 10:41 pm

    Hiya Jane, just tried your recipe and my mixture came out very dry and crumbly, I followed through and just popped it into the oven and took them out and let them harden when they were done and there just keep crumbling? By any chance do you know how to stop this or how to change this for future baking?
    They still tasted great but I think they’d be so much nicer if they went into my mouth and not crumble all over the place haha!
    Thanks so much ☺️

    • Jane's Patisserie on February 1, 2020 at 9:58 pm

      The mixture is dry – but that’s normal. They do also have a lot of chocolate in, so if they’re slightly over baked they could break apart after cutting!

      Can I use any other chocolate with these? X



    • Jane's Patisserie on May 4, 2020 at 9:55 am

      Basically yes! Soft centred chocolates are better frozen before using though!



  9. Jess on January 26, 2020 at 11:38 am

    Hi Jane, I made this recipe this morning and the mix ended up being slightly dry/crumbly and it’s made the overall bake slightly dense. Any tips? Thanks so much!

    • Jane's Patisserie on January 26, 2020 at 2:19 pm

      The mixture is quite dry – it just needs a little less baking time perhaps.



  10. Adam Walker on January 14, 2020 at 10:37 pm

    Hey,

    By kinder chocolate bars do you mean the small bars with the white center like these?

    Many thanks,
    Adam

  11. Kim on December 24, 2019 at 4:50 am

    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

    • Jane's Patisserie on December 24, 2019 at 8:44 am

      Yeah, I’m in the UK and we call it cornflour!



  12. India Ede on October 30, 2019 at 12:40 pm
