This easy Caramel Slice recipe is hands down one of my all time favourite slice recipe – a big call I know, but once you make this you will know what I’m talking about. My Mum actually put me onto this recipe and likes to make an even more decadent version (if that is ever possible!!!) by using Hazelnut Chocolate as the icing, you can find that recipe here.
This is also one of Mum’s favourite recipes, so it only made sense to make a batch when she was visiting us recently. She even managed to drag herself away from playing with the boys (they are just a little obsessed with their “Nanny”) and gave me a hand making this.
Needless to say once the boys cottoned on to the fact we were ‘making’ they were both pushing their little chairs up to the kitchen bench eager to help. As much as I love cooking with them, this is one recipe which isn’t toddler friendly so they had to make do stirring their blocks around in bowls instead. The hardest part of making the slice is how long you have to wait for it to set and the top was covered with more than a couple of fingerprints where I had eagerly checked it’s consistency.
When the time came this slice certainly didn’t disappoint and between the four of us we may have consumed a few too many pieces!

Easy Caramel Slice
Ingredients
- 1 cup 150g of plain flour
- ½ cup of coconut
- 125 g of butter
- ½ cup 70g of brown sugar
- Filling
- ⅓ cup 120g of golden syrup
- 125 g of butter
- 2 x 400g cans of condensed milk - Make sure you use a good quality brand I use Nestle as I've heard that the caramel hasn't set too well when other brands of condensed milk (homebrand/aldi) have been used.
- Topping
- 220 g of milk chocolate
- ½ teaspoon of vegetable oil
Instructions
- Preheat your oven to 180 degrees and line a 18 x 28cm slice tin with baking paper.
- Melt the butter.
- Place the flour, coconut, sugar and butter into a large bowl and mix with a metal spoon to combine.
- Pour the mixture into your prepared slice tin and flatten the surface with a spoon. Place the tray into the oven and bake for 16 - 18 minutes or until it's golden brown.
- In the meantime you can start making the caramel filling. Place the butter, condensed milk and golden syrup into a small saucepan and stir oven a low heat for approximately 8 minutes or until the mixture is lovely and thick.
- Pour the caramel over the base once it has cooked and put it back in the oven to bake for a further 20 minutes or until the caramel is golden.
- Remove the slice from the oven and allow it to cool for 10 minutes before place it in the fridge to chill.
- Once the slice has chilled, place the milk chocolate and vegetable oil into a microwave safe bowl and cook for 30 second spurts until it's melted. Pour over the top of the slice and return to the fridge for 1 hour or until set.
- Cut into small squares to serve.
Nutrition
Please note it’s important to use a good quality condensed milk when making the caramel (I use Nestle) as the caramel doesn’t seem to set as well when using other brands such as home brand or Aldi.

Hi Lauren, I too am from Aus but have moved abroad. I had forgotten about caramel slice until I cm across this delicious looking recipe. I’m super excited to make it because you have made it (IMO) the correct way, with a bucket full of caramel. I have all the ingredients in the cupboard and I’m going to go make it right now! Also, in my experience corn syrup is a better substitute for golden strip than maple as corn syrup has the desired consistency but the flavour is not as good as GS.
Lauren
Hi Annita, Yep, if you are going to make caramel slice it needs to be FULL of caramel! Thanks so much for the tip, I’ll add a note at the bottom of the recipe. I hope you enjoy it x
Carol
If you mix clear karo (corn syrup brand) 85% with 15% molasses you should get something that has the cane sweetness of the golden syrup. But not the bitterness that is often associated with molasses. FYI: In the USA we don’t have anything on the shelves called treacle. I had to look it up to find that it is similar to molasses.
But what is a slice pan. I’m in the USA and have never heard of such?
Lauren Matheson
Thanks for the the tips Carol 🙂
A slice tin is just a baking dish, the one I use is approximately 18 x 28cm
Mary
Hi
I really want to make these but only have a 9×13 pan. Can I use this to replace the slice tin 18×28? Thanks so much!!
Lauren
Hi Mary, Is that 9 x 13 inches or cm? That should be ok, you may just need to adjust the cooking time and keep a close eye on it while ti’s cooking.
Eden
Thank you so much for sharing! Such a delicious recipe, yum!!
Lauren
I’m so glad you enjoyed it – thank you!!
Teigan
Fantastic recipe! Thank you so much for sharing. Had to cook the caramel mixture on the stove for a bit longer than suggested but it set beautifully, oven times suggested were perfect!
Made this for my boyfriend and I’m sure it will be demolished in no time!
kate
ahhhh i only have 1 can of condensed milk i have to wait to make it – nooooooooo
Lauren
Oh no!! It’s really worth the wait I promise!
Kate
Can I make the base one night and then make the rest the next night for work the next day so the base will be two days old by the time it gets eaten – will that matter
Lauren
Hi Kate, I haven’t tried doing that before but I don’t see why you couldn’t. I would keep it covered in the fridge until you finish the recipe though. I hope that helps 🙂
Barbara Linn
This sounds so good! I LOVE caramel. I am wondering what size pan you are taling to in non-metric terms. Also, is the 180 degrees centigrade?
Lauren
Hi Barbara, Thanks so much for your message! I just converted the measurements of the pan and it’s around 11 x 7 inches – I hope that helps! Yes, it is it 180 degrees celsius, which is approximately 350 farenheit I believe. I hope you enjoy the recipe, have a great weekend 🙂
Ginny
I’m not a fan of coconut – can you suggest a substitution or can I just leave it out?
Lauren
Hi Ginny, you can certainly leave it out, just add a little extra flour to the mixture.
Michelle
What is golden syrup?
Lauren
Hi Michelle, it’s similar to treacle only a little lighter. You could try maple syrup or light corn syrup as alternatives. Hope that helps!
Alison
Woodmans and Amazon sell Lyles Golden syrup.
DeeDee Elliott
You can buy Lyles Golden syrup at World Market stores in the USA.
Sam
Omg your slice looked so delicious.. I had to try. Not sure where I went wrong but my caramel was a lot lighter than yours and that runny that when I tried to slice it it all just went down hill from there, still tasted beautiful.. Just didn’t look so appealing.. The only thing I can think I’ve done wrong is substitute the golden syrup for maple syrup? Any thoughts?
Lauren
Hi Sam, Sorry to hear it didn’t quite work out. I think maple syrup should still work well, I’d suggest cooking your caramel for a bit longer on the stove top to let it thicken a little more and get a really good colour. Also make sure it’s nice and brown/bubbling when you take it out of the oven.
Alison
I’m in the process of making this but I have a feeling I might know where you went wrong. If you’re American like I am you might have initially thought the oven temperature was low. But it’s in Celsius not Fahrenheit. :$ so if that is the case, then the oven wouldn’t have cooked it properly. Not sure, just a thought.
Lauren Matheson
Thank you Alison x Yes, I’m from Australia and all temperatures are in celsius x
