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!

Life of Dozer
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!!)
Can the plain flour in the base be substituted one to one for gluten free plain flour?
I love this recipe so much! It is my new favorite dessert. I add about a pinch of salt into the caramel, and it makes it perfect. Dozer gets a 10/10, so cute! Thank you so much for this recipe Nagi. 🙂 xxx
The salt made it perfect. Thanks!
Thank you Nagi, used your recipe for my first time attempting chocolate caramel slice and the result was perfect and absolutely delicious!! I really didn’t expect to get it looking perfect the first time I made it, but all your tips really worked. Thank you for all your recipes, I have loved every single one I have used! Whenever I am looking for a recipe now, I always look at your website first 😊
I made this for the first time for a morning tea and halfway through my partner asked me to make another one so there was extra for him 😀😀😀 I followed the recipe step by step and both turned out perfectly!! It was an absolute hit at the morning tea 😋😋😋
I’ve had caramel
Slice homemade from
Someone the base was awesomely chewy do you know how I would achieve that?
This recipe is absolutely delicious and not that tricky to make. Just an FYI for anyone making it in a time crunch. It takes much longer than an hour to make as there is lots of cooling time. Wish this was included in the total time but sadly not. Besides that it’s an extremely easy to follow recipe that turns out delicious. ❤️
Delish! Hubby is not a massive fan of coconut so I replaced it in the base with 1/2 a cup of quick oats, two crushed weetbix and 2Tbsp golden syrup. It’s chewy and yum – this was apparently good enough to write into my hard-copy recipe book!
Felt like a sweet and baked the chocolate slice. Satisfying in every possible way.
These are sooooo sweet! They came out looking nice. The caramel is slightly runny and the base wants to stick to the parchment paper. I greased the parchment, but obviously not enough. Easy enough to make, but the sweetness is just too much for me.
Perfect every time! Such a hit with the whole family, work colleagues and for friends! As I’m trying to watch our sugar intake I substituted half the amount of sugar with a brown sugar sweetener and half the chocolate for the top layer with sugar free chocolate – no difference in flavour at all, but half the sugars and calories!! Now I can feel slightly less guilty when reaching for another piece or three!
I messed up the first time as I didn’t read the recipe so my husband ‘saved’ my caramel but the secong time round, I made sure I read the steps properly and I’m super proud of the caramel slice I made! One of my favourite childhood treats and now I am confident to make my own! I like a thinner chocolate crust so I used the rest of the chocolate to make dipped strawberries, so good!
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!
Hi Melinda. Wow! I was just touched by your story! I am sprinting to coles to buy these ingredients! Hopefully I’m not single forever and I’ll be able to feel that tingle you got when your kids ate your caramel slice.
Kind Regards,
d. nut
Love your recipe
love your dog.
I make my caramel using sweetened condensed milk in the slow cooker (no other ingredients). Would this work in this recipe?
Amazing! Worked perfectly 🩷 your recipes are my go to’s!!
Can the coconut be substituted for people with allergies??
I’m not a lover of coconut so I subbed in the same amount of almond meal (ground almonds) & it worked perfectly.
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.
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!!
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.
Great recipe, very popular
