Caramel Slice (2024)

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 (1)

Caramel Slice

It’s practically un-Australian for a bakery to NOT sell Caramel Slice. Withasimple coconut biscuit base, soft caramel filling and a chocolate topping, it’sone of those treats that’s craved by kidsandgrown ups.

I’ve only ever known it as a Caramel Slice, but I was quite interested to learn that overseas, it’salso known asMillionaire’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, andthat, 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 fromsome 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 theeasy 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:

Caramel Slice (3)

  • 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!

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

Recipe video above. An easy Caramel Slice recipe that delivers as promised - a creamy caramel filling that sets perfectly (no more runny caramel!) and chooclate that doesn't crack when you cut into it!

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!

Recipe Notes:

1. Desiccated coconut is called "Sweetened Coconut Flakes" in America. It is finely shredded coconut, not the large flakes.

2. Sweetened condensed milk - Do not use skim (low fat), caramel will not set. Also ensure you use sweetened condensed milk (thick sweet milk) that comes in cans, NOT evaporated milk.

3. Cooling base - creates a neater line between caramel and biscuit layer, I rarely do this (pictured caramel slices weren't cooled!)

4. Caramel - If you don't stir constantly, little brown specks will appear, being caramel caught on the bottom of the saucepan. It's not a major problem if you have some brown specks, won't affect flavour just visual. If desperate, strain them out (yes I've done that - mother rang in the middle of caramel making, wouldn't stop talking! 🙄)

5. Smooth chocolate -The refrigeration times is such that the caramel is mostly set, cool but not cold.That way the chocolate doesn't set too quickly when you pour it on, so when you shake the pan it will spread out evenly.

If you want to make a textured top like the ones in this photo,refrigerate the caramel until fridge-cold - 1 hr+ in the fridge. When the chocolate is poured on, it will firm up faster. As it starts to thicken, use a spatula or knife back and forth across the surface.

6. To slice neatly, remove from the fridge 5 minutes before cutting. Run knife under warm (not hot) water, wipe dry then cut quickly. For very neat slices, clean knife between each cut - I did this for the photos. Don't make the knife too hot otherwise the chocolate melts when you cut it and smears into the caramel.

7. STORAGE: Airtight container for up to 5 days, but if it's so hot that the chocolate melts, keep it in the fridge and bring to room temperature before serving.

8. COCONUT FREE BASE: A few readers have asked if it is possible to make the base without coconut. This recipe won't work without coconut but the shortbread base in my Lemon Bars recipe is a perfect substitute. Please DOUBLE the recipe.

9. Nutrition - ignore it. You can eat salads all next week!!?

How to fix caramel candy that is too soft? ›

If caramels are too soft, that means the temperature didn't get high enough. Again place the caramel back into a sauce pan with a couple of tablespoons of water and heat to 244°F. If you don't have a candy thermometer, you can test with a cold water test. Details on how to use this method can be found here.

How to thicken caramel for caramel slices? ›

To make the filling, place the golden syrup, condensed milk and butter into a small saucepan over low heat. Stir continuously for 10-15 minutes or until the caramel has thickened (make sure your heat is very low and you continue stirring until the sauce has obviously thickened).

Can I use milk instead of heavy cream for caramel? ›

Try milk instead.

If you don't want to make a special trip to the store, you can use whole milk with an extra tablespoon of butter in place of the heavy cream. It may not be quite as thick, but it will work in a pinch!

How do you fix failed caramel? ›

How do you firm up caramel? ›

To thicken a caramel sauce, use one tablespoon of cornstarch or tapioca starch (sometimes known as tapioca flour) and one tablespoon of water per cup of caramel. Then simmer the caramel, stirring it constantly with a wooden spoon until it becomes thick.

Why is my caramel not solidifying? ›

Candy thermometers—like this instant-read thermometer—let you know exactly what stage the caramel is in (thread, soft-ball, firm-ball, hard-ball, soft crack or hard crack). It's an easy way to prevent soft caramel that won't set, which happens if the caramel doesn't reach a high enough temperature.

What is the trick to making caramel? ›

“It's best to start a wet caramel over low heat until the sugar has dissolved, then increase the heat to medium for caramelization,” says Mel. “As the water evaporates, the sugar eventually caramelizes.” The wet method is used to take the caramel to various stages, including soft ball, firm ball, hard ball, etc.

Will caramel thicken as it cools? ›

Keep in mind that when your caramel sauce cools, it will naturally thicken anyway. However, if it's really thin when hot, let it simmer for about 10 minutes in the pan while stirring it constantly. This will evaporate some of the water and make the sauce thicker.

How to fix split caramel? ›

If the sauce has separated then warming it gently and stirring occasionally should help it to come back together. If it still has a film of fat on the surface after warming then whisking in a tablespoon of hot water (from a freshly boiled kettle) can also help.

Can I use condensed milk instead of caramel? ›

Most of the time, people cook caramel by heating up regular or brown sugar until it turns into a smooth and creamy substance. However, you can also make caramel out of sweetened condensed milk, creating the same great sauce with a unique, extra-sweet kick.

Why does boiling condensed milk make caramel? ›

When you add heat to your ingredients, they undergo a chemical reaction known as the “Maillard reaction.” This means that the sugar is cooked to the proper moisture level and caramelization occurs. You know when this happens as the mixture changes colour to a rich brown.

Do you add milk when melting caramel? ›

The key to getting it right is to use soft caramels as opposed to hard. You must also add some sort of liquid, such as milk or cream, to prevent the caramels from drying out. Knowing these tricks will help you to melt caramels with ease.

Why won't caramel set? ›

you simply haven't cooked it enough-- possibly your microwave is less powerful (the original recipe doesn't specify a wattage for cooking the caramel) or the butter you used has a higher water content. You could try cooking the mixture for a little longer, and seeing if it sets up firmer.

Why does my caramel keep separating? ›

Sometimes separated toffee or caramel can be saved by removing the saucepan from the heat and stirring constantly until it comes back together into a smooth mixture. Gradually return it to the heat, stirring constantly. You can also try adding a spoonful or two of very hot water to the toffee to help it come together.

Why is the caramel not sticking to the apple slices? ›

Apples have a waxy coating that will prevent the caramel from sticking, so it's important to wash and dry it off. Make sure the apples are cold, which helps prevent the caramel from slipping off.
