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!!)
Cat says
This caramel slice recipe is amazing. I like to add a light sprinkling of flaked salt (not too much) on top of the caramel layer after it has baked – I find it helps cut the sweetness.
Nagi says
Sounds great Cat – just like a salted caramel slice 🙂 N x
Sarah Sleeman says
Could you substitute the flour ratio for a gluten free flour??
Nagi says
I haven’t tried with this one Sarah, would love to know if you give it a go! N x
Helen says
I subbed gluten free flour for the normal flour the second time I made this and it was just as good (just slightly crumbly on the base). Both times I lightly toasted the coconut first to bring out the coconut flavour. Thank you for providing such delicious recipes for us all!!!

You’re so welcome Pam! N x
KB says
This recipe is top notch. It was honestly better than most caramel slice I have store or bakery bought. Will be saving this one – everyone loves it particularly my husband. Thanks Nagi 🙂
Jezmynn says
Fantastic! Made many rounds and they’re hot cakes! Want to try a variation, do you think almond flour will work in place of all purpose flour?
Sharna says
hi what can I do if the caramel is to runny
Nagi says
Hi Sharna, if the caramel is too runny, it means it needs to be cooked longer on the stove to ensure it sets properly. N x
Tam says
Made this yesterday, came out perfect! Only problem now is having self control to not demolish it all.
Love your recipes, we had this as dessert after your delicious Beef Cheeks
Nagi says
I know this problem all too well Tam 😂

Hi Nagi, it’s Julie-Ann here. Well, I’ve tried your roast lamb….success! I’ve tried your roast chicken…..success and today I made the millionaires shortbread……absolutely beautiful. I’ve made millionaires many times but the shortbread has always crumbled away when I’ve cut it. Not today! It’s the best ever thanks to you. We can’t stop eating it. 🙄Thankyou for the step by step guide. I’m going to try the lemon bars soon. X😋
Nagi says
WAHOO!!!! Perfect Julie-Ann! N x

Sonia Gerayli says
As a kiwi living in the states, I’ve been missing a bakery caramel slice!! First time making it and this recipe is great!!! Easy to follow and tastes delish!! Only thing I changed was doubled the vanilla and added vanilla in the base (clearly a fan) hehe. It tasted so good that I gifted 80% away only to be disappointed that mine only lasted a day. So I made it again a few days later. Thank you!
