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!!)
Melinda Burge says
My mum used to make caramel slice when I was a kid, and we would take our single pieces to school as a morning tea snack. She didn’t make it too often. I have always been a little too fond of food! Recently I started buying it from the supermarket but at $7.50 a slab figured it would be more economical to make it at home. Imagine my trepidation at my first attempt one Friday night. I did it slowly, ensuring I got each step right. By 3am it was set and ready. There was no holding me back! It lasted two days, which was longer than I anticipated. A great recipe. Thanks, Nagi!
Diane says
Love your recipe
love your dog.
Kath says
Amazing! Worked perfectly 🩷 your recipes are my go to’s!!
Jen T says
Can the coconut be substituted for people with allergies??
Kerry says
I’m not a lover of coconut so I subbed in the same amount of almond meal (ground almonds) & it worked perfectly.
Lana says
Every single recipe from Nagi is a hit!!!! Sweet or savoury doesn’t matter. This caramel slice was no exception.
I will say the caramel was very very sweet for my taste, next time will probably half the sugar, because I will be making this again for sure!
Thank you Nagi for sharing your delicious recipes with us.
Laura Power says
I loved this dessert! We’re in the US and my Australian friend asked for caramel slice for his birthday – he said it was perfect!!
Rebekah says
I have to say this is the best recipe! My family is hooked! I tried making it with both Nestle condensed milk and the Aldi brand and the Aldi brand comes out on top! It worked and tasted much better than the Nestle brand. I think because they use whole milk to make it unlike Nestle who use skim.
Jessica says
Great recipe, very popular
lucretia battle says
easy instructions – turned out perfect – scrumptious- not sickly sweet – can be made in advance – another winner and keeper – your recipes are divine and easy to follow
Kara says
First time I’ve ever made caramel slice and I’m so glad I chose Nagi’s recipe to do it!
I made it for my 2 young daughters, who loooove caramel at the moment.
It was an absolute hit! They both loved it.
Very simple to make, but definitely very time consuming. Lucky it was the school holidays when we made it, but even then, they lost interest in helping as it was time consuming.
Coconut base was enjoyed by the husband – a nice touch – he advised.
Tastes really good and not overly sweet. I’m not a fan of sickly sweet caramel slices.
Was a great slice. Would only make again if I had lots of time up my sleeve.
Lynda says
Question, the base of my caramel slice is quite hard, what am I doing wrong?
Lorraine Hosgood says
I followed this recipe exactly except instead of vanilla essence, I used coffee essence – brilliant. This is a regular one for me now.
Mahlia says

Vineeta Gogia says
Awesome recipe . Can we freeze the brownie?
Emma says
Delicious! And so simple. Every time I make these, they are a big hit ❤️
Melanie Hui Jun Teng says
This is a really great recipe! The caramel set perfectly and it’s not tooth-achingly sweet. The base is a really nice crisp/chewy texture. I reduced the amount of chocolate because I find the flavour overpowers but that’s just preference! Thank you Nagi!
Lisa says
Can I double the caramel slice filling?
Roz says
After trying many different recipes over the years this is by far the best. It turned out perfect, was tempted to use coconut oil instead of vegetable but as my first time making this I followed the recipe.
Chewie says
Tried and tested all the caramel slice recipes I’ve seen and this is by far the best one! Another recipe for the family book to pass on to the kids!! Thank you Nagi!!
