Ingredients

For the Base

2 cups plain flour

1 cup desiccated coconut

1 cup brown sugar

250 grams unsalted butter, melted

1 teaspoon vanilla extract

For the Caramel Filling

2 cans (395 grams each) sweetened condensed milk

200 grams unsalted butter

4 tablespoons golden syrup

1 cup light brown sugar

2 cups roasted macadamia nuts, roughly chopped

1 teaspoon vanilla extract

½ teaspoon sea salt

For the Chocolate Topping

300 grams milk chocolate

150 grams dark chocolate

2 tablespoons vegetable oil or coconut oil

½ cup roasted macadamia nuts, finely chopped

Flaky sea salt for garnish (optional)

Equipment

23 x 33 cm rectangular baking tray

Large mixing bowl

Medium saucepan

Wooden spoon

Baking paper

Offset spatula or spoon

Sharp knife

Cooling rack

Preparing the Baking Tin

Preheat the oven to 180°C.

Line the baking tray with baking paper, leaving some overhang on the sides. This makes removing the slice much easier after chilling.

Lightly grease the paper and sides of the tray.

Making the Base

Place the flour, coconut, and brown sugar into a large mixing bowl.

Stir until evenly combined.

Pour in the melted butter and vanilla extract.

Mix thoroughly until the ingredients resemble wet sand.

Transfer the mixture into the prepared baking tray.

Press firmly into an even layer using the back of a spoon or the bottom of a measuring cup.

Pay special attention to the corners to ensure a uniform thickness.

Bake for approximately 15 to 18 minutes or until lightly golden.

Remove from the oven and allow it to cool slightly while preparing the caramel filling.

The base should be lightly crisp but not overly browned.

Making the Caramel Filling

Place the condensed milk, butter, golden syrup, and brown sugar into a medium saucepan.

Cook over low to medium heat.

Stir continuously to prevent sticking or burning.

As the mixture heats, the butter will melt and combine with the condensed milk.

Continue stirring for approximately 10 to 15 minutes.

The caramel will gradually thicken and become smooth and glossy.

Once the caramel begins to pull slightly away from the sides of the pan while stirring, remove it from the heat.

Add the vanilla extract and sea salt.

Mix thoroughly.

Fold in the chopped roasted macadamia nuts.

Ensure the nuts are evenly distributed throughout the caramel.

The aroma at this stage should be rich, buttery, and deeply caramelized.

Assembling the Slice

Pour the warm caramel mixture over the partially cooled base.

Spread evenly using an offset spatula.

Take your time to create a smooth, level surface.

Return the tray to the oven.

Bake for 12 to 15 minutes.

The caramel should appear slightly darker and more set around the edges.

Remove from the oven.

Allow the slice to cool completely at room temperature.

Once cooled, place it in the refrigerator for 1 hour.

This chilling step helps the caramel firm up before adding the chocolate layer.

Preparing the Chocolate Topping

Place the milk chocolate and dark chocolate into a heatproof bowl.

Add the oil.

Melt gently over a pan of simmering water or in short microwave bursts.

Stir until completely smooth.

The combination of milk and dark chocolate creates a balanced sweetness that complements the rich caramel.

Allow the chocolate to cool slightly but remain pourable.

Pour over the chilled caramel layer.

Spread evenly to the edges.

Sprinkle the finely chopped macadamias over the top.

If desired, add a light scattering of flaky sea salt.

The salt enhances the caramel flavor and balances the sweetness beautifully.

Chilling the Slice

Place the tray into the refrigerator.

Allow the slice to chill for at least 3 hours.

For the cleanest cuts, refrigerate overnight.

The layers will become firm and easy to slice.

Cutting and Serving

Remove the slice from the refrigerator.

Allow it to sit at room temperature for 10 minutes.

Using the baking paper overhang, lift the slice from the tray.

Place on a cutting board.

Use a large sharp knife.

For perfectly clean cuts, wipe the knife between slices.

Cut into squares, rectangles, or bars according to your preference.

The finished slice should reveal distinct layers:

A golden coconut biscuit base.

A thick caramel layer packed with crunchy macadamias.

A smooth chocolate topping decorated with nuts.

Tips for the Best Caramel Macadamia Slice

Always use roasted macadamias for maximum flavor.

Stir the caramel constantly while cooking.

Do not rush the caramel process by increasing the heat.

Allow each layer to cool properly before adding the next.

Use good-quality chocolate for a smoother topping.

Chilling overnight greatly improves both texture and flavor.

A small pinch of sea salt enhances the richness of the caramel.

For extra indulgence, drizzle melted white chocolate over the finished slice.

Variations

For a salted caramel version, increase the sea salt slightly and finish with extra flaky salt.

For a white chocolate version, replace the chocolate topping with melted white chocolate.

For a coffee caramel slice, add 1 teaspoon instant espresso powder to the caramel mixture.

For a festive version, add dried cranberries and chopped macadamias to the topping.

For a tropical variation, mix toasted coconut flakes into the caramel layer.

Storage

Store the slice in an airtight container in the refrigerator for up to one week.

For longer storage, freeze individual pieces for up to three months.

Separate layers with baking paper before freezing.

Allow frozen slices to thaw in the refrigerator before serving.

Serving Suggestions

Serve with freshly brewed coffee.

Pair with hot tea for an afternoon treat.

Enjoy alongside vanilla ice cream for an indulgent dessert.

Serve on dessert platters during holidays and celebrations.

Cut into bite-sized squares for parties and gift boxes.
