Caramel Slice
This fudgy melt in your mouth Caramel Slice is made of layers of coconut biscuit base, a silky smooth creamy caramel filling and is topped with a thin layer of dark chocolate. It’s a classic Aussie treat with an interesting history. Let’s chat about that later.

Hey friends! Popping in with a deliciously easy to make granny style slice, a classic in Australian bakeries since the 70’s! It’s easy to make and uses simple ingredients and the end result is a deliciously smooth, sweet bar that is great for gifting, putting on party tables or taking to picnics.

The star of the show is that perfectly set caramel layer in the center. It holds its shape when you slice the bar up when it’s set, and melts in your mouth with each bite. It’s really a winning combination.
Isn’t This Just A Millionaire Shortbread?
No, however the two are related! The very first Caramel Slice appeared in a women’s magazine in Australia in the 70’s. Millionaires Shortbread!, a Scottish invention dates way back to the Elizabethan times and is made using shortbread as a base and the caramel layer is a little chewier. They both have a biscuit base, caramel layer and chocolate top. Can I be honest though? Even though Millionaires Shortbread is divine, I love this version more.
Let’s Talk Caramel.
The caramel layer in this dessert is mostly made up of condensed milk. I use it in my Caramel Chews because it gives you a deliciously smooth caramel and something that’s able to hold it’s shape.

The addition of golden syrup in the caramel layer helps add some toffee flavor and helps keep it soft and chewy. Overall, it’s got a deep caramel flavor. That’s the point in a caramel slice right?
What I love about making it is that you’re not over the stove stirring for an hour, it’s cooked a little on the stove, just enough to melt the ingredients together, and then you let it do it’s thing in the oven where it finishes cooking. This is why it sets so perfectly!
How To Make The Biscuit Base


- Add all ingredients to a large mixing bowl and mix together to form a crumbly dough that sticks together when bunched up in your hand.
- Spread out in your lined 9-inch baking tin and press down firmly and evenly. Bake for 12 minutes. Take out of the oven once it’s baked.
How To Make The Caramel Filling


- Add the butter, sugar and golden syrup to a saucepan and stir until melted and it comes to a gentle bubble. Stir in the condensed milk until it comes to a boil. Then continue stirring for 2 minutes.
- Pour on top of the biscuit base. Spread around evenly. Bake for 10 minutes until it turns a golden color.
That Thin Chocolate Layer!


- Melt the chocolate and oil together. Once baked, allow to cool to room temperature. Pour the chocolate on top. Cool in the fridge until set.
- Slice into 4 x 4 slices.
What’s The Best Way To Slice This Up?

The chocolate layer is made up of melted chocolate and a dash of oil. This helps soften the chocolate so that it doesn’t set super hard again. That means that when we slice into it, there’s less chance of it cracking or snapping. The way to get super clean and crisp slices for your Caramel Slice is to use a hot knife! Run a large, sharp knife under hot tap water from your kettle, then wipe dry using a towel and slice. Clean your knife and run under hot water again with each slice. Time consuming, but it gives you those super clean slices so that you can see each layer.
Tips And Tricks For Recipe Success!
- Cook the caramel on medium heat – caramel burns easily, so you want to cook on low to avoid this and make sure you keep an eye on it!
- Use a good quality chocolate for the chocolate layer. It makes all the difference flavor wise. I used Nestle Dark Cooking Chocolate Buttons. You can even use eating chocolate like Lindt Chocolate.
- Measure out using kitchen scales – measuring ingredients out by weight and not cups is the best way to get consistent results every time! I wrote all about this in my post about using digital kitchen scales!
FAQ’s for Caramel Slice
Storage
Store in an airtight container for up to 5 days. Pop it in the fridge if it’s a warm day.
Why didn’t my caramel layer set?
This will be because it wasn’t cooked enough. Make sure it comes to a boil when you have it on the stove and cook for the stated amount of times. Don’t stop stirring and watch it like a hawk or it will burn.

Caramel Slice
Serves 16
Ingredients
Biscuit Base
- 130 g all-purpose flour, plain flour
- 65 g brown sugar
- 40 g desiccated coconut, unsweetened
- 100 g unsalted butter, melted
Caramel Filling
- 125 g unsalted butter
- 70 g brown sugar
- 55 g golden syrup
- 2 tsp vanilla extract
- 395 g sweetened condensed milk, see notes
- Pinch of salt
Chocolate Topping
- 150 g milk cooking chocolate, can use dark/semi-sweet
- 1 tbsp vegetable oil
Instructions
Biscuit Base
- Preheat a fan-forced oven to 160C / 320F (180C / 355F for no fan). Line the bottom and side of a 22cm / 9-inch square baking tin with baking paper, leaving some overhang to easily lift and remove. Set aside.
- Biscuit base – Add the flour, brown sugar coconut and melted butter to a large mixing bowl and use a spatula to mix until well combined and a dough forms.
- Bake – Spread and press into the bottom of the baking tin as evenly as you can. Your hands should be ok, but you can use a lightly greased spatula as well. Bake for 12 minutes or until golden. Allow to cool while you make the caramel.
- Lower oven temp – Lower oven temperature to 150C / 300F (170C / 340F for no fan).
Caramel Filling
- Syrup – Add the butter, sugar and golden syrup to a large saucepan and place on medium heat. Gently stir until the mixture is melted and it begins to bubble around the sides.
- Finish Caramel – Add the condensed milk and continuously stir until the mixture begins to bubble again. Continue stirring the bubbling mixture for exactly 5 minutes. It will darken slightly in color. Take off the heat and add the vanilla and salt and stir until combined.
- Bake – Pour the mixture on top of the cooled biscuit base. Bake for 10 minutes. Once baked, allow to cool to room temperature, then chill in the fridge for 20 minutes or until just warm.
Chocolate
- Add the cooking chocolate and oil to a heat proof bowl. Double Boiler: add on top of a pot of gently simmering water, making sure the bottom of the bowl isn’t touching the water and stir until melted. Microwave: microwave for 30 seconds at a time, stirring each time until smooth.
- To Finish – pour on top of the cooled slice and spread evenly using a spoon or offset spatula. Allow to set in the fridge for 20 minutes.
- How to get perfect clean slices – run a large knife under hot water and carefully dry with a towel. Slice into 4 x 4 bars, cleaning the knife, warming it and drying it with each slice. Serve.

So excited for you guys to try this recipe!
Very excited to make these. The photo is awesome the the process is lovely. Love a beautiful caramel with shortbread, then capped with chocolate. Total win.
Hey Gwenyth, so glad you’re excited to make them! Just a quick note that this one has a buttery biscuit base, not a shortbread. If you’re after that classic shortbread texture with the same flavours, my Millionaire’s Shortbread might be more what you’re looking for. N x
So excited for you guys to try this recipe! It’s fudgy and easy to make.
So excited for you guys to try this recipe! It’s so fudgy.
So excited for you guys to try this out!
Hi can I ask why you bake the caramel for 1ins in the oven? Does this have to be done or can you just leave it to set overnight?
Hi Jen, that’s a great question! it helps it set, stick to the base and enhances it’s overall flavor. I don’t think it would set the same way if it wasn’t finished in the oven. Hope that helps! N x
For the base; would you change the quantities for the other ingredients if you want to leave the coconut out?
Hi Zoe, hmm, not sure. I haven’t tried the recipe without adding the coconut sorry!
Hi, the recipe states brown sugar. Should I use light brown sugar or dark brown sugar or muscavado sugar?
Sorry, I live in Scotland, we have a number of brown sugar options!
Hey Heather, light brown sugar works best for this recipe. It gives the perfect balance of sweetness and caramel flavor. Hope that clears it up! N x
I’m also not a desiccated coconut lover, so I substituted in the same weight of rolled oats and it worked out well for me! I can’t guarantee it will work perfectly for you since I’m not a professional like Nick, but I find substitutions tend to work better than just complete omissions.
So glad you liked the recipe with the substitution Rachel! N x
Hi can you freeze the caramel slice
Hi Marguerite! Yes, that should be fine. Freeze wrapped in plastic wrap for about a month. That completely at room temperature before serving 🙂 N x
They were delicious! My son was visiting and loved them. I had a little trouble getting my chocolate to firm up. Not sure what I did wrong. Kept them in the fridge and the chocolate was fine!
Thanks for another great recipe!
Hey Virginia,
I’m so happy to hear you and your son loved them! As for the chocolate, it sounds like it just needed a little extra time to set—especially if the kitchen was warm. Keeping them in the fridge definitely helps! Next time, you could also try adding a touch more vegetable oil to keep it smooth while setting. So glad the recipe was a hit!

Made this on the weekend for friends… they’re all raving about it! So yummy!
Hey Daniel, So glad to hear they loved it! Thanks for making it! N x
Can you please convert your recipes to American measurements etc? Thank you
Hey Karen. I use grams for accuracy, especially with baking, but I have a guide on how to use kitchen scales if you’re new to them. They’re inexpensive and make a big difference to your results. N x
This is another winner Nick: been making millionaires shortbread for years and years and when I told my husband I was making this he said don’t mess around with the recipe: anyway, he absolutely loved it and told me to make this one now
Hey Jan, that’s such a win! I love that you converted a caramel slice loyalist. So glad he enjoyed it and thanks for giving my version a go. N x
I can’t find the Nestle dark cooking buttons. Is there a suitable substitute?
Hey Karen, you can use any dark chocolate that’s labelled as suitable for baking. The Nestlé buttons are just easy to melt and made for that purpose, but a block of good quality dark cooking chocolate will work just as well. N x
What brand of dessicated coconut do you use? I live in the States and haven’t seen it in the stores. I can’t wait to make these.
Thank you!
Hey Mary, I used the McKenzie’s one from Safeway here in Australia, but any unsweetened finely shredded coconut will work just as well. Hope you love the slice when you make it! N x
There are two different sets of instructions for cooking and timing the caramel. I was confused as to which I should follow, but ended up following the recipe and not the the instructions at the top of the page.
Hi Maureen! Do you mean the baking times for the caramel? If so, thanks for pointing that out! I’ve gone in and updated the recipe N x
Yes the baking times and the stirring on stove top. One says 2 minutes and the other says stir for exactly 5 minutes once bubbling. Turned out great though and will make again
Hey Maureen, glad you loved the recipe! N x
I have always been alittle scared to make Carmel Slice and I bake alot….when I saw this recipe I thought I’m going to just do it!!
Well first time and it was amazing! I followed your recipe to the letter and even read through twice.
Thanks for sharing😍
Thanks Virginia! I’m so glad you gave it a go. Hope you loved it! N x
Hi nick. Can I substitute the brown sugar in the base for white sugar??? Thanks heaps
Hi Belinda, you could. It would taste different though and probably not brown as dark. Lwt me know how it goes! N x
What is a reccommended substitute for the Golden Syrup ingredient?
Corn syrup light or dark or dark? Maple syrup? Thanks
Hey Roger, light corn syrup is your best bet as a substitute for golden syrup in this recipe since it gives the closest texture and sweetness—dark corn syrup or maple syrup will change the flavour and might make the caramel runnier or more intense, so I’d avoid those if you want to keep the balance right. Also, what’s with the 4 stars? You haven’t even tried the recipe?
Thanks for the recipe. Could I substitute a nut oil like hazelnut oil instead of vegetable oil?
Thanks
Hey Mark, you can definitely try hazelnut oil. Any mild nut oil should work as long as it’s suitable for melting chocolate. Just keep in mind it might add a subtle nutty flavour, which could actually be really nice here. N x
