Kit Kat Biscuits are crunchy kit kat packed cookies! These quick and easy baked treats are simple to make and fast to bake. Kit Kat Cookies with a glass of milk or cup of tea yes please!
There are many things to love about this recipe and these are the reasons to love it the most!
- Simple ingredients: everything we need to make this recipe is readily available at the local shops. There is nothing difficult about the basics and the combination of them works.
- No egg and no milk: I try to keep (most) of my recipes simple without a huge list of a million ingredients. This recipe only needs 6 ingredients!
- Baked in less than 15 minutes: the cookies will cook in 12 to 15 mins. That is super fast and allows you to have them quick smart if unexpected guests drop in!
- Chocolate Chip Cookies are good, but Chocolate Biscuits with chocolate bar pieces in them, yummo right!!
- Kid Friendly: get them to help you bake or sift the flour and icing sugar as you go. This is a great recipe to make with or for kids!
- Budget Friendly: the ingredients are economical and we only need 1 block of Kit Kit chocolate. You can purchase home brand (non premium) products and stick to your budget at the same time.
- Lunch Box Treat: have a popper, an apple, some cheese and crackers plus a biscuit in the lunch box for a diverse range of snacks!
Top Tip 1: These are the perfect recipe for when you need a baked goods plate the next day. Quick, easy and not involving hours of work and clean up!
Everything you need to make the recipe is shown in the photo below (take it shopping!). For exact measurements and detailed instructions, scroll to the printable recipe card at the bottom of the post.
As you can see, the recipe calls for:
- Kit Kat Chocolate Bars: we need 1 standard block of this and you can either blitz it in the microwave or use a knife and chopping board to cut it into small pieces.
- Icing Sugar: Also known as confectioner's sugar, this is a soft, white powdered form of sugar. It is often used in baking and is perfect to dust over cakes and cupcakes. We need to sift this ingredient.
- Plain Flour: we need slightly more of this than the sugar. We also need to sift this ingredient. Use a measuring jug for accuracy as you portion it out.
- Butter: I recommend using regular, unsalted butter. You will find it easier to cream if it is at room temperature. It also helps to chop it into small cubes so that you are not starting with one hunk of butter.
- Cocoa Powder: I usually sift this also after the flour and then continue mixing to combine. It is not essential that you sift this ingredient, but worthwhile if you are prepared to.
- Vanilla Extract: occassionally I use Imitation Vanilla, either is fine. Vanilla Extract is more expensive than imitation vanilla. If you are on a tight buget, use the imitation version.
Top Tip 2: As soon as you know you will be making the biscuits, grab the butter out so it will soften when you come to use it.
Here are the step by step instructions to make the biscuits. You will need beaters. Electric, hand held are fine to use!
- Cream butter with electric beaters (Photo 1)
- Add vanilla extract or imitation vanilla (Photo 2)
- Sift icing sugar and add to creamed butter (Photo 3)
- Beat till sugar, butter and vanilla is combined (Photo 4)
The butter will turn from very yellow to a lighter colour soft yellow as it creams.
Once that is done, sift the icing sugar into the bowl and continue to combine.
Top Tip 3: Use a spatular in between adding ingredients to scrape down the sides of the bowl, ensuring the mixture is consistently combined.
- Add sifted flour and cocoa powder (Photo 5)
- Beat to combine (Photo 6)
- Use a spatula or clean hands to firm up biscuit mixture (Photo 7)
- Turn the KitKats into chunky pieces (Photo 8)
You can use a knife and chopping board to chop the Kit Kats up or you can blitz them in a food processor.
If you chop them they will stay more together than it you blitz them.
Blitzing them will mean they will be more of a crumb than a chocolate bar.
Top Tip 4: If using the knife method to chop them use not the tip but the middle of the knife. The firmer pressure will ensure more of the Kit Kat wafer stays together. Using the tip will make it break apart.
How to Make Kit Kat Biscuits
- Portion biscuits onto baking tray (Photo 9)
- Use 2 finger tips to push slightly to flatten (Photo 10)
- Decorate the top of the biscuits with Kit Kat pieces (Photo 11)
- Bake for 12 to 15 mins (Photo 12)
To portion the cookie dough onto the baking tray, you can use a mini cookie scoop as I am showing you in the photos or you can use 2 spoons.
It is important to give the biscuits a little space as they will spread as they bake and you don't want them running into each other.
The broken kit kat pieces will stick onto the top of the cookies if you push them slightly into the wet biscuits.
They only take between 12 to 15 minutes to bake, so you can remove them from the oven after that time.
Top Tip 5: Leave them on the baking tray to cool. If you try and move them off when they are warm, the biscuits will crumble into pieces!
The biscuits work well as a snack in the kids lunch boxes, a special treat during the day or paired with tea of coffee.
You can wrap them in clear plastic bags and decorate with a coloured ribbon to give them as gifts!
Substitutions and Variations
Here are the switch ins, outs and ups and downs you might want to consider for this recipe:
- Leave out the cocoa powder and have the biscuits be vanilla instead (See my Malteser Biscuits as a guide).
- Add some white or milk chocolate chips.
- Use a different flavour of Kit Kats. Be it the dark or white chocolate version, Mint version or caramel. There is even a variety called Milk Choc Chunk Cookie sold in block form!
- Switch out the Kit Kat pieces and use Rolo, or your favourite chocolate bar instead!
How to Guide
How to Store
The best way to store these cookies is in a sealed, air tight container.
How to Freeze
If you want to freeze the cookie dough, I recommend doing that before you have added the broken up kit kat pieces.
Simply roll the dough and wrap it tightly with cling wrap.
Once you are ready to bake it, remove it from the freezer and allow it to defrost.
Then add in the broken kit kat pieces and continue the steps from there.
How to Reheat
These cookies need to cool a little after baking as it helps them to set or firm up.
To reheat them, pop the microwave for 30 seconds or dunk them in your tea or coffee!
Here are my top tips and tricks for getting these biscuits cooked to perfection every single time:
- Start by grabbing the butter out of the fridge. This will make it softer when you come to cream it. Room temperature butter is always easier to work with than solid cold butter.
- Chop the butter into pieces. This also makes it easier to use. If using hand held beaters, the pieces will seperate and cream quickly. Whereas one solid block of cold butter will take forever to cream.
- Baking mats are easier to use than baking paper or tin foil. You don't have to grease them and you also don't have to risk peeling stuck baking paper of the base of the biscuits. (They are also reuseable!).
- My preference for sifting is to use a wire colander (or sieve) with a fine weave. I like these better than a hand held squeaky one that has a narrow circumference. Simply add the dry ingredients, and move the sieve from left to right tapping back and forth with your other hand.
- On some level I can't say this one enough (to reassure you): let them cool!! If you remove them from the baking sheet too quickly, they will crumble and fall apart. Be patient, let them cool and once they are, use a flat silicon flexible turner to slide under them and transfer them to the cooling rack.

- Store in an air tight container.
- Note 1 I find silicon baking mats much easier to use than baking paper or alfoil. They are also reuseable and you don't need to grease them!
- Note 2 You can use Imitation Vanilla (cheaper) if you want, to the equivalent amount, ie 1 teaspoon.
- Note 3 You might know this as confectioners sugar. It is a soft, white powdered form of sugar that is perfect to use when baking. It is also excellent as a decoratice choice when dusting cakes and cupcakes.
- Note 4 Give the biscuits a little space on the baking tray and offset them from one another so they don't collide as they bake and spread.
- Note 5 The biscuits will be cooked in 12 to 15 mins. Remove them from the oven if they start to change colour on top. It is important to let them cool before removing them from the baking mat as they need to cool and will firm up as they do. If you remove them too quickly, whilst they are still hot, they will break apart. The best utensil to move them from the tray, is a flat one that you can slide under each biscuits and pick up.
