This is a Caramel Slice that works as promised – the creamy caramel sets perfectly and will never be runny, the chocolate won’t crack when cutting it and the caramel won’t ooze out. It’s an easy recipe with no thermometer required.
Essentially, this recipe fixes all the grievances I had with other recipes I’ve tried over my lifetime!
Caramel Slice
It’s practically un-Australian for a bakery to NOT sell Caramel Slice. With a simple coconut biscuit base, soft caramel filling and a chocolate topping, it’s one of those treats that’s craved by kids and grown ups.
I’ve only ever known it as a Caramel Slice, but I was quite interested to learn that overseas, it’s also known as Millionaire’s Shortbread (appropriate!), Caramel Shortbread, Chocolate Caramel Bars.
Doesn’t really matter what you call these. Just the sight of them surely brings a smile to anyone’s face, and that, my friends, is a universal language. 🙂 (“That” being a Food Smile)
Reader Rachel says “Wow! This was really fantastic. I’ve been hunting for a caramel slice that cuts well, doesn’t ooze or crack and had enough filling. This is perfect! So tasty, I love how crunchy the base gets and my mum adores it! I only made it last night, but I don’t think it will last long!”
A Caramel Slice recipe that actually works
I’ve tried countless recipes over the years including from some well known cooks, and classic “best ever” recipes but always experienced problems such as:
-
Runny caramel
-
Chocolate topping cracked when it was cut
I think some recipes make Caramel Slice overly complicated, trying to make the caramel using a traditional candy making method which calls for a thermometer and exact caramel temperatures.
Scratch that. Make Caramel Slice the easy way using condensed milk. Tastes just like you get from the bakeries!
What goes in Caramel Slice
Here’s what you need to make Caramel Slice:
-
Base – a coconut biscuit base, not too sweet (because the caramel filling is plenty sweet!)
-
Caramel filling – the secret ingredient here is condensed milk. So we make a caramel using sugar and butter, then we add condensed milk which thickens it and makes the caramel set;
-
Chocolate topping – the secret to making sure the chocolate doesn’t crack when cut is a touch of oil!
How to make Caramel Slice
There are 3 components to Caramel Slice:
1. Biscuit base – just mix the ingredients together in a bowl, press into a pan and bake:
2. Caramel Filling – bring the butter and brown sugar to a simmer (this is caramel!) then stir in condensed milk. Whisk over low heat for a few minutes to give it some colour, then pour onto the base and bake. Baking is what makes the caramel set once cool.
3. Chocolate Topping – simply melt the topping then spread on the caramel base. To achieve a perfectly smooth surface, just shake the pan gently.
And proof – the chocolate DOES NOT CRACK when you cut into it!!!
These were fridge cold too – you can see the surface is sweating on this hot summer day I made them!
And a side view so you can see how it slices neatly, showing each individual layer:
Normally I try to show a bit of self respect with up close “bite shots” and use a fork…. But I’m not going to lie to you – in this case I just took a big fat bite out of this Caramel Slice!!!
Caramel Slice – Q&A
Here’s a little Q&A section for common questions and problems people face making Caramel Slice!
Why is my caramel slice runny?
Common problems that causes runny caramel include: using low fat condensed milk (ie. skim condensed milk) instead of full fat milk (it will not set properly), you didn’t bake the caramel layer (this makes sure it sets) or you used a recipe where the caramel filling is made without condensed milk (in which case you need a candy thermometer to achieve an exact temperature to ensure it sets).
How do you keep chocolate from cracking when cutting?
Add 1 tablespoon of oil to the melted chocolate – this makes the chocolate topping slightly softer so it doesn’t crack!
How long does caramel slice last?
5 days in an airtight container – in the fridge if it’s warm weather, otherwise in the pantry is fine.
That’s the proper answer.
But does Caramel Slice ever last FIVE WHOLE DAYS in anyone’s house??? 😳😳😳 – Nagi x

Caramel Slice
Ingredients
Base
- 1 cup flour, plain/all purpose
- 1/2 cup brown sugar , loosely packed
- 1/2 cup desiccated coconut (US: sweetened finely shredded coconut, Note 1)
- 125g / 4.5oz unsalted butter , melted
Caramel filling
- 125g / 4.5oz unsalted butter , roughly chopped
- 1/2 cup (80g) brown sugar , loosely packed
- 1 tsp vanilla extract (or essence)
- 395g / 14oz sweetened condensed milk (1 can, 300ml) (Note 1b)
Chocolate Topping
- 200g / 7oz dark or milk melting chocolate (US: semi-sweet chocolate chips)
- 1 tbsp vegetable oil
Instructions
Base
- Preheat oven to 180°C/350°F (fan 160°C)
- Grease and line a 28x 18cm (lamington pan) / 7" x 11" rectangle pan with baking/parchment paper (Note 2). Have overhang for ease of removal.
- Mix together Base ingredients and press into a pan (I use an egg flip)
- Bake for 15 minutes until the surface is golden. Cool in fridge if you have time (Note 3).
Caramel
- Lower oven to oven to 160°C/320°F (fan 140°C)
- Place butter, sugar and vanilla in a saucepan over medium low heat. When the butter is melted, whisk to combine with sugar, then just leave it until it comes to a simmer.
- When bubbles appear, add condensed milk. Whisk constantly for 5 minutes (Note 4), until you start getting some big slow bubbles on the base.
- Once bubbles start appearing, whisk for 1 minute, then pour onto Base. Tilt pan to spread evenly.
- Bake for 12 minutes. Don't worry if you get splotchy brown bits (this happens with ovens that don't distribute heat evenly).
- Cool on counter for 20 minutes then refrigerate 30 minutes - bottom of pan should be warm but surface cool (not cold) to touch. (Note 5)
Chocolate
- Place chocolate and oil in a microwave proof bowl. Microwave in 30 second bursts, stirring in between, until chocolate is fully melted (takes me 4 x 30 sec).
- Pour over caramel, spread with spatula. Then gently shake pan to make the surface completely flat.
- Refrigerate 1 hour or until set. Remove from fridge and leave out for 5 minutes to take chill out of chocolate slightly. Then cut into bars or squares to serve!

Dozer in his swanky bathrobe. On a scale of 1 to 10, how ridiculous do you think he looks in his bath robe??? 😉
(And on a scale of 1 to 10, how much do you want to see me in my matching robe?! 🤣 It was a GIFT!! I would never!!)
DeeDee says
I’ve been looking for a chocolate-caramel cookie/bar for a long time. The last recipe I tried, the caramel set so hard we couldn’t even cut it with a knife. Seriously, we broke a knife. Had to toss it, and it wasn’t cheap to make. This looks SO yummy!
Nagi says
I hope you give this one a go, promise you wont break a knife!
Aarefa says
Never made Caramel slice before and had always heard about the struggle of keeping the layers separate. This recipe is amazing! So easy to make and the thing I love most is – it doesn’t have too many ingredients unlike some other recipes. I am an Australian who moved to Canada 7 months ago, and it’s really handy that the recipe describes ingredients as available in North America as well (which as I’ve learnt are not named/available quite the same as in Australia)
Alexandra Grimaldi says
Is there a substitute for the coconut? Thank you! Can’t wait to try it!
Allie
Nagi says
You could use the base for my lemon bars if you prefer not to use coconut – N x
Kim says
Hi, could you please tell me what I could substitute vegetable oil with for the chocolate topping?
Nagi says
Coconut oil or canola oil 🙂
Tina S. says
I love caramel slices, any time I’ve visited Australia I must have. I haven’t tried making them yet, but your recipe is definitively one I will try. My question is have you or another reader tried making this gluten free and if yes, what did you do? Seems the crust is the only gluten part. I’m in America if that helps for product reference. Thanks!
Megan says
I’ve just tried making it gluten free, but complicated it somewhat by making it dairy free as well! I used margarine and coconut condensed milk to replace the dairy and gluten free plain flour in the base – I think the recipe for the base might need tweaking for gluten free, as I found the caramel soaked through the crust, which means you lose the crunch! Still tasted amazing though 🙂
Claire Stronge says
Can you taste the coconut at all? About to make this gorgeousness tomorrow with my 4 year old but I know he will be sad if he taste coconut,
Do you think it would be a waste of time trying to sub in almond meal for the coconut?
Nagi says
Hi Claire, it’s to overly coconutty – but almond meal would be a great sub – N x
Larissa says
What can I use in place of coconut seeing as I’m allergic?
Nagi says
Hi Larissa, you could use the base that I do in my lemon bars in place of this base 🙂
Wendy says
Eggs are not mentioned in this recipe and yet they are used?
Nagi says
Hi Wendy, there are no eggs used in this recipe 🙂
Ananasunderthesea says
I love this recipe and it is by far the best I have ever made, I also used an 85% dark chocolate to go on the top which really helped cut through the sweetness. Will defiantly make again 😀
Nagi says
I’m so glad you loved it!!
Megan says
Thank you thank you thank you. I’ve been eating caramel slice ever since I can remember and my late Nannie always used to make it. This is the first time ever (and I’ve made LOTS of attempts) that I’ve put the base in the oven & it took me back because it smells EXACTLY like her kitchen when she made it. That’s what awesome cooking is about – it transcends time and space.
The final product was perfect too. Have made it a couple of times. About to go again for my dad’s birthday 🙂
Nagi says
Oh, that’s just so sweet I just shed a tear. the best feedback I could ever hear Megan ❤️
Stephanie says
I’ve made this recipe many times and it’s always been a favourite in my household. I noticed today that your weight for the butter in the caramel filling says “4 oz/125 grams” but shouldn’t that say “113 grams”? Right above that for the base, the recipe says 4.5 oz/125 grams and that one is correct. The extra butter in the filling has never been an issue but I thought you might want to know about the typo.
Emma Faulkner says
My Partner told me this was the best caramel slice he as ever eaten. He has eaten ALOT of caramel slice. Also all my workmates raved about this and it disappeared like lightning.
Nagi says
WOOT!!! You’ll be the favourite with all your workmates!
Gia says
Hi there, can this go in the freezer? i enjoy made it 6 times in the last month and have only just perfected the caramel filling. had my element right down on low so it never got to the stage it was meant to, turned up the heat a little and voila! hubby even said it tastes amazing and not as oversweet as my last batches
Nagi says
That’s great to hear Gia! I imagine this would be fine to freeze – N x
Angeli Yuson says
I can’t wait to make these! I am gonna substitute the shortbread crust from your lemon bars instead of the coconut base. I am a fellow Aussie here and was looking for an easy recipe for caramel slice. Will share how I go!
Nagi says
Love to know what you think Angeli!
Monique says
Made this tonight – so easy and so delicious! My husband is onto his third or fourth piece and is still raving about it 🙂
Nagi says
That’s great to hear Monique!
Lula Moon says
I’ve just made this piece of heaven tonight and it was super fun and easy. My husband isn’t a fan of chocolate so I used white chocolate and coconut oil (instead of vegetable oil) melted in a zip lock bag in hot water. Yummy ❤️
Nagi says
That’s a great idea Lula!
Intan says
Try again last nite…. yayyyyyy this time I got it perfect…. so happy with that, give some to my daugter who have a cafe in city and she said my caramel slice way way better than one she sell from bakery, her husband a chef in they cafe, finnis off all caramel slice last nite, surprise becouse he never can finnis one slice from they cafe…
Thank you Nagi.. your caramel slice is the best from the best… 😍
Nagi says
That’s such a great compliment Intal!!! ❤️
Natasha Cabaron says
Hi I want to know if u can use salted butter for this recipe
Nagi says
Hi Natasha, yes you can (my default is always unsalted so I can control the salt in a recipe)
Intan says
Make it last nite, follow all the step and correct amount of ingredients.
Bake on 180 c for 15 minutes, still not get litle brown on top after 30 minus get a bit brown.
For caramel too, waiting litle dark spots after double in time.
My caramel come out hard base and dry caramel on top, so layer chocolate on top doesn’t stick properly.
I will try to give another go, can I take it out from the oven (15 minutes) before it get litle brown for the base and take caramel out before they get bubble and dark litle sport appears?
Nagi says
Hi Intah, sorry you had trouble with this one, sounds like the base and caramel overcooked, hence it being dry and hard. Take it out at the 15 minute mark and you should be ok. I hope you attempt it again and let me know how you go! – N x
