There are some bakes that never go out of style, and caramel slice is one of them.

With its buttery biscuit base, gooey caramel centre and smooth chocolate topping, it's been a favourite at Australian bakeries, school fêtes and family gatherings for decades. Rich enough to feel indulgent, yet simple enough to make at home, it's the kind of treat that always disappears quickly.

If you've been searching for the perfect caramel slice recipe, this classic version delivers every time. Better still, pair it with a great cup of tea, and you've got afternoon tea sorted.

What is a caramel slice?

Caramel slice is a classic Australian dessert made up of three irresistible layers: a buttery biscuit base, a thick layer of caramel made with sweetened condensed milk, and a smooth chocolate topping.

The combination is rich, chewy and wonderfully satisfying. While it looks impressive, it's surprisingly easy to make, making it a favourite for bake sales, celebrations and weekend baking sessions.

As with many classic recipes, every family has its own version. Some prefer dark chocolate, others swear by milk chocolate, and a sprinkle of flaky sea salt has become a popular finishing touch.

Caramel slice vs Millionaire's Shortbread: what's the difference?

At first glance, caramel slice and Millionaire's Shortbread look almost identical.

The biggest difference is the base.

Traditional Australian caramel slice uses a biscuit-style base made with flour, coconut and brown sugar, giving it a slightly chewy texture. Millionaire's Shortbread, which originated in Scotland, uses a rich, buttery shortbread base that's firmer and more crumbly.

The caramel layer is also a little different. Australian caramel slice is typically made with sweetened condensed milk, creating a soft, creamy filling that's easy to slice. Millionaire's Shortbread often has a firmer caramel with a deeper, more toffee-like flavour.

Whichever version you prefer, both deserve a good cup of tea alongside them.

How to make a caramel slice: a step-by-step guide

Ingredients

For the base

• 1 cup plain flour

• 1 cup desiccated coconut

• ½ cup brown sugar, lightly packed

• 125g unsalted butter, melted

• Pinch of salt

For the caramel filling

• 395g tin sweetened condensed milk (full fat)

• 60g unsalted butter

• 2 tbsp golden syrup

• 2 tbsp brown sugar

• ½ tsp vanilla extract

• Pinch of salt

For the chocolate topping

• 200g dark or milk chocolate, chopped

• 1 to 2 tsp neutral oil

• Optional flaky sea salt

Step-by-step instructions

BASE

1. Preheat your oven to 180°C. Grease and line a lamington tin with baking paper, leaving enough overhang to lift the slice out later.

2. In a large bowl, combine the flour, desiccated coconut, brown sugar and salt. Stir through the melted butter until the mixture resembles damp sand.

3. Press the mixture firmly into the prepared tin. Using the back of a slightly wet spoon helps create an even layer. Bake for 12 to 15 minutes, or until lightly golden. Remove from the oven and allow it to cool slightly.

CARAMEL

4. Place the condensed milk, butter, golden syrup, brown sugar and a pinch of salt into a saucepan over medium-low heat. Stir until the butter has completely melted and the mixture is smooth. Keep stirring as it cooks gently for about 5 to 8 minutes. You'll notice the caramel becoming slightly thicker and a little darker in colour. Once it reaches that stage, take it off the heat and stir through the vanilla.

5. Pour the caramel over the baked base and spread evenly. Return to the oven for 10 to 12 minutes, until the caramel looks set with lightly golden edges. Cool completely for at least one hour, or refrigerate to speed things up.

CHOCOLATE

6. Melt the chocolate with the neutral oil in short bursts in the microwave, stirring well between each burst until smooth. Pour over the cooled caramel and spread right to the edges. If you like, finish with a sprinkle of flaky sea salt.

7. Refrigerate for 1 to 2 hours until completely set.

Tips for the perfect homemade caramel slice

• Let each layer cool before adding the next. Rushing this step can cause the layers to mix together.

• Adding a little neutral oil to the chocolate helps prevent it from cracking when sliced.

• For clean slices, lightly score the chocolate with a warm knife before it fully sets, then cut all the way through once chilled.

• Store your homemade caramel slice in the fridge until ready to serve.

The best tea to serve with caramel slice

Caramel slice is wonderfully rich, which makes tea the perfect partner.

A well-chosen brew balances the sweetness and refreshes your palate between bites.

Everyday Brew or Earl Grey Strong

A robust black tea is the classic Australian pairing for caramel slice. The natural tannins help cut through the caramel's richness while complementing the buttery biscuit base.

If you like a traditional afternoon tea, Everyday Brew is hard to beat. For something with a little citrus lift, Earl Grey Strong is equally delicious.

Chai Tea

If you enjoy warming spices, Chai Tea makes a brilliant match.

The cinnamon, cardamom and cloves contrast beautifully with the creamy caramel, making every bite feel even more indulgent.

Peppermint Leaves

Looking for something lighter?

Peppermint leaves are naturally caffeine-free and wonderfully refreshing. Its bright minty flavour cleanses the palate, making it a great choice if you're serving caramel slice after dinner or in the evening.

FAQs

Why is my caramel slice caramel runny and not setting?

Runny caramel is usually caused by not cooking it long enough. Make sure you simmer the mixture gently, stirring continuously, until it thickens, then bake it on the base.

Why does the chocolate crack when I cut a caramel slice?

Chocolate naturally hardens as it cools. Mixing in a teaspoon or two of neutral oil helps keep it slightly softer. Scoring the chocolate with a warm knife before it's fully set also helps create neat slices.

Can I make a caramel slice without condensed milk?

Yes, although the texture and flavour will be different. The traditional Australian caramel slice recipe relies on sweetened condensed milk to create its signature creamy caramel layer.

How long does a caramel slice keep, and should I refrigerate it?

Yes. Store caramel slice in an airtight container in the refrigerator, where it will keep well for up to one week.

Can I freeze a caramel slice?

Absolutely. Slice it first, place baking paper between the layers and store in an airtight container for up to three months. Defrost overnight in the fridge before serving.
