What is a cookie bar?

A cookie bar (or bar cookies) is where cookie dough is pressed into a baking tin and baked. It’s then cut into individual bars or slices. This differs to traditional cookies which are usually made free form.

How do you know when a cookie bar is done?

It can be tricky to know exactly when cookie bars are done, especially when they have lots of fillings (like this Kinder Nutella cookie bar recipe for example!). The usual sign is that the top is crisp and golden. Don’t worry too much though – so long as the top is golden and crisp, once it’s completely cooled, everything should firm up anyway.

Ingredients

Ingredients are important and there are limits to substitutions. This section will help you know all there is to know about the ingredients needed to make these epic cookie bars.

  • White Chocolate Cookie Dough – You can buy shop bought but I highly recommend making your own. Search ‘white chocolate chip cookies‘ at the top of this page for my easy peasy recipe! (It’s the one I used to make these bars.)
  • Kinder Bars – The multipack ones that are 12.5g each fit nicely into an 20cm/8″ square baking tin. You will need 22 of them.
  • Nutella – Yes you can buy cheaper alternatives but there’s no substitution for the real thing. Buy the real deal and your tastebuds will thank you!

Recipe tips

It doesn’t matter how good we are at baking or how much experience we have, we still make mistakes! Here’s some helpful tips to ensure you don’t do that and get to enjoy perfect white chocolate Kinder Nutella cookie bars first time!

  • Make sure your white chocolate cookie dough has been chilled before using. If it’s room temperature, it can go quite flat and greasy when baked.
  • Use white chocolate chips instead of chunks in the cookie dough as it will be easier to press into a flat layer.
  • Make sure you leave a border around the Kinder bar and Nutella layers so the cookie can prevent them from leaking out.
  • Allow the bars to cool completely before attempting to remove from the tin and slice. Otherwise things could get very messy!
  • Store your bars in a metal container instead of plastic. It helps them keep their texture for longer.

How to store white chocolate Kinder Nutella cookie bars

Store your bars in an airtight metal container at room temperature and consume within 5-7 days. Plastic containers can make sugar ‘sweat’ and alter the texture quite quickly, hence why I prefer to use metal.

(For a printer friendly version, see the recipe card at the end of this post)

Ingredients

Here is what you will need to make 16 ginormous bars! (They could easily be halved.)

  • 1.2kg (42.3 oz) White Chocolate Chip Cookie Dough *
  • 22 x 12.5g (0.44 oz) Kinder Bars
  • 300g (1 Cup) Nutella Spread

*My chewy white chocolate chip cookies recipe makes 810g. You would need one and a half batches of it to make these bars. I recommend using chips (not chunks) to make it easier to press into layers.

Essential equipment

  • 20cm (8″) Square Baking Tin
  • Metal Spoon

White chocolate Kinder Nutella cookie dough bars instructions

First of all, lightly grease and line your baking tin and preheat your oven to 180ºC/Fan 170ºC/356ºF. Then divide your white chocolate chip cookie dough (1.2kg | 42.3 oz) into thirds. (I recommend using weighing scales to do this for accuracy.)

Next, dot one third of the cookie dough over the base of the tin.

Then, using either the back of a metal spoon or your hands, press the cookie dough into a nice flat, even layer.

Time to unwrap all of those Kinder bars (22 x 12.5g | 0.44 oz) and place them onto the cookie dough! Make sure you leave a little border around the edge so the cookie dough can encase it in.

Now for another layer of cookie dough! Dot the second third over the top of the kinder bars then press into a flat, even layer. Exactly as you did before. (Either using the back of a spoon or your hands.)

Next, spoon the Nutella (300g | 1 Cup) onto the middle of the cookie dough and smooth outwards with a spoon. Just like you did with the Kinder bars layer – make sure you leave a little border around the edges.

At last, the final layer! This one can be a little tricky so take your time. Carefully dot over the remaining third of the cookie dough. You may find it easier to almost flatten each piece you place on first, as it can be challenging to flatten cookie dough over smushy Nutella! Try to flatten the cookie dough into a nice neat layer while stopping the Nutella from squeezing through..

Bake in your preheated oven for 35 – 40 minutes until beautifully golden and crisp on top. Do remember to check your bake in the last 10 minutes of cooking time, as all ovens vary.
