Chocolate Box Cookie Bars!

Easy and Delicious Chocolate Box Cookie Bars – your favourite chocolates, in Cookie Traybake form!

Right.. roll with me here. Leftover Chocolates DO EXIST. No doubt when I post this recipe, I will get comments saying “leftover chocolates?! what are they?!” as everyone thinks they are being funny… but in all honesty, nearly every house will have them.

Over a period like Christmas, and easy and common gift is a box of chocolates. And if you are like me, and you get given a whole lot of Chocolates such as Celebrations, Heroes, Roses and so on… you will have far too many to eat. 

It’s not so bad for a big family, and a family that don’t receive too many chocolates… but I always get given loads. Whether they are gifted from companies because of my blog, presents from friends or family, or my fiancé buying another box as he was ‘spontaneous’.. I have too many.

It’s only me and my fiancé in my house, and when we have SEVEN tubs of chocolates, it’s just too many. Therefore, the easiest thing to do is to shove them all in a bake! Whether its a no-bake treat such as Rocky Road, or something like this.. it’s a much easier way of using them up, and being able to give them away!

I love putting chocolates into a bake as I often prefer them that way – I don’t often eat chocolates on their own as I have so much sweetness in my life already, and I feel like giving away a box of chocolates you got given yourself is a bit odd… 

For these, I used my regular and favourite cookie bar recipe that you can find in my other ones, such as my oh-so-popular Mini Egg Cookie Bars for example. You just take out the chocolates featured in that recipe, such as the Mini Eggs, and replace it with chocolates!

The good thing about this, is you can use all of the chocolates in the box, use up the ones you don’t like if you are giving the cookie bars away, or use the ones you do like but if you fancy something a bit different! 

Cookie bars as I will say again and again are delightful. The cornflour IS IMPORTANT TO THE BAKE. It changes the texture, changes the bake, and improves them tenfold. This is why Cornflour is in a lot of my cookie recipes, so please don’t leave it out!

This recipe is also great to use after Christmas when you are a little fed up with all the food, as you can make the cookie bars and freeze them! You can defrost some when you fancy a cookie! Or, you can make up the cookie dough, and bake them as you please!

If you fancied making this, but making it a chocolate cookie dough… take out 30g of the flour, and 1/2tbsp of cornflour, and add in 30g of cocoa powder instead! Both ways are utterly delicious!

You can see from the photos that they are a tasty bake, with all the different chocolates poking through! If you use a lot of chocolates that have a runny centre such as Quality Street caramels, I would recommend freezing them before baking, but if you are using a large combination such as I have, I generally don’t bother!

These really are such an adaptable and utterly SCRUMPTIOUS bake – They are a great bake for all sorts of occasions, and also a great way to use up all that ~leftover~ chocolate that DOES ACTUALLY EXIST!!! Enjoy! x

Ingredients

  • 275 g Plain Flour
  • 1 tsp Bicarbonate of Soda
  • 1/2 tsp Sea Salt
  • 1 tbsp Cornflour
  • 115 g Unsalted Butter/Stork
  • 55 g Granulated Sugar
  • 135 g Light Brown Sugar
  • 1 Medium Egg
  • 1 tsp Vanilla Extract
  • 100 g Milk Chocolate Chips
  • 300-400 g Chocolate Box Chocolates (I used Celebrations!)

Instructions

  • Preheat your oven to 190C/170C Fan and line a 9x9inch Square Tin with parchment paper, and leave to the side for now.
  • Whisk/Mix the Plain Flour, Bicarbonate, Salt and Cornflour together so its evenly distributed – leave to the side.
  • In a larger bowl, melt the butter. Add in the two sugars, and whisk for about 2 minutes so the sugar starts to dissolve and the mixture is smooth.
  • Add in the Egg and the Vanilla, and whisk again briefly till smooth. (I used an electric whisk)
  • Add in the Dry Ingredients and the Chocolate Chips and mix with a spatula till a thick cookie dough is formed.
  • Finally, add in the Chocolates! I don't chop mine up. Fold through the mixture as best you can!
  • Press the mixture into the bottom of the tin - Bake the traybake in the oven for 18-22 minutes, until the top of the cookie bake looks ‘dry’!
  • Leave the cookie bake to cool for about 10 minutes, then leave to cool fully on a wire rack. Cut the bake into 4×4 for decent sizes, or 5×5 for smaller ones! Enjoy!

Notes

  • I used Celebrations as I bought SO many. I used all of them, as I'm not fussy when it comes to Celebrations.. but use your favourites if they're for you! Or even use up the ones you don't like and give them away!
  • You can easily use others such as Heroes, Roses, Quality street and so on - however, if you are using a lot of soft centre ones, I would recommend freezing them first. 
  • These delicious beings will last in an airtight container for up to 5 days, but honestly, they’ll be eaten before then.
  • Try Microwaving them when they’ve cooled if you want a gooey cookie, or even add a scoop of ice cream!

      How did you mix it? the mixture is reasonably dry, but does come together when mixed correctly (Watch some of my cookie bar videos as the recipe is the same) – it’s also worth making sure you are using the correct ingredients, the correct tin, and measuring correctly!

    Hi.
    I’m just wondering, I don’t have any sea salt so would I just leave out or replace it with table salt?

    Hi Love this recipe. I think your blog is fab. I was just wondering what your thoughts are on unsalted butter v cooking marg (stork or supermarket own) and tub v block. Do you think it makes much of a difference xxxxx

    These look so so good! I’m dying to try them. I was wondering is there any way an egg can be substituted in your recipe here? Sorry for asking. Thank you so much

      The only alternative I’ve tried is the flax seed one which worked well!

      Ooo I never knew about that! Is it on your blog? Trying out as many vegan recipes as possible for my little boy who is dairy soya and egg free!

      It’s not yet I’m afraid!! I will be posting more vegan recipes over the next few months but not quite yet!! So you mix one tablespoon of flax seed with 3 tablespoons of water to replace one egg!

    Hi Jane, I was looking for some advice, I tried making these first time they came out great however on the 2nd attempt the taste of the baking soda came through really strong, not sure what went wrong, followed the amount specified in the recipe I was wondering if you have ever had this issue? thanks

      That can happen when too much is put in, or it’s not mixed in very well so there will be more in some areas than their should be – the measure should be level, and definitely not more than recommended, and make sure to mix it in really well!

    I love using your recipes as they are all delicious and they have all turned out really well! I can’t access any light brown sugar at the moment so what would you recommend instead?

    Hi can you substitute the butter for margarine in this? I did half of each and it turned out like a cake unfortunately. Thanks

      I’ve made them using both and they’ve been fine with both. If it’s cakey it’s probably over baked or something else has been substituted as well.

      Oh I see thanks for letting me know. I also didn’t use brown sugar and the butter wasn’t unsalted, could it have been either of these? Thanks !

      What sugar did you use as the alternative?

    These look great ! I’m struggling to get chocolate chips at the moment so was thinking of doing just an assortment of chocolate bars I have already would that be ok ? And just chop them up ? Eg Kit Kat’s , milkyway , crunchies etc! If so would you still say the do the 100g plus the 300-400g ? Thanks in advance

      Hey! Yes so for any recipe requiring chocolate chips you can easily chop up a basic chocolate bar into chip size! And then yes, you can use any sweet on top!

    Hello,

    These really do taste amazing. If I was going to cook in a 12x7inch baking tin should I double the recipe?

      A 12″x7″ tin is actually the same volume as the 9×9″, so should work as it already is!

    Just baked these and they came out great! it took a few attempts to start them as I didn’t read the recipe through properly first and every time I went to start I was missing something aha, but it was certainly worth the wait. Thank you

    Hi, I made this earlier with my fan oven I cooked for 20 minutes on 150 as every time I baked the cookie on 170 it’s always dry inside. The cookie was perfectly soft & gooey after baking on 150. Just wanted to check this is ok to eat though? Would the eggs have had enough time to cook. Thanks

      Its probably that your oven is running hotter than you think so thats why it drys out at the hotter temp – but yes they will still be edible!! x
