What You Need

This decadent white chocolate caramel slice may seem like a slightly extravagant treat, however the ingredients required are really only basic pantry and baking staples.

Note: Please scroll to the recipe card at the bottom of the post for ingredient quantities and the full detailed method.

For The Base

plain flour - also known as all-purpose flour
brown sugar
desiccated coconut - this is coconut that has been finely grated and dried
butter - either salted or unsalted is fine to use in this recipe.

For The Caramel Filling

golden syrup - see my tips below for golden syrup substitutes
sweetened condensed milk - make sure you use full fat sweetened condensed milk as the skim version will not set the filling firmly enough. I like to use the Nestle brand sweetened condensed milk
butter - again, either salted or unsalted is fine to use.

For The Chocolate Topping

white chocolate - you can use either 'melts' or a block of good quality white chocolate such as Cadbury's baking chocolate
vegetable or coconut oil - optional, see my tips below. This helps to stop the chocolate topping from cracking when it's cut into pieces.
edible gold sugar dust - optional. I like to sprinkle this over the top of my chocolate layer while it's still melted to give the slice a pretty and sparkly look! You can buy this from the baking section of many major supermarkets or speciality cooking stores.

Step By Step Instructions

Follow my simple steps to make the perfect White Chocolate Caramel Slice!

Note: Please scroll to the recipe card at the bottom of the post for ingredient quantities and the full detailed method.

Step 1 - Prepare Base

Preheat your oven to 180 degrees celsius, and grease and line a slice tin.

Sift flour into a bowl, add the brown sugar and coconut, and mix to combine.

Melt butter and add to the dry ingredients.

Mix until well combined and crumbly.

Press firmly into your prepared slice tin and bake for 15 minutes.

Step 2 - Prepare Filling

Gently heat golden syrup, condensed milk and butter over a low heat in a small saucepan.

Continue to stir this for about 10 minutes until it has obviously thickened - it should coat the back of a spoon well.

Pour the caramel filling over the base, and then bake for another 15-20 minutes.

The filling should be golden around the edges and bubbly, and firm to the touch when cooked.

Set aside to cool before adding the white chocolate layer on top.

Step 3 - Add The Chocolate Topping

Melt the white chocolate and vegetable or coconut oil (optional) in the microwave and stir until smooth.

Pour the chocolate topping over the cooled caramel layer.

Expert Tips & FAQ's

What can I substitute golden syrup with?

Golden syrup is a cane sugar syrup popular in Australian, New Zealand and British baking recipes.If you can't get hold of golden syrup, you can replace it with corn syrup, honey or maple syrup(corn syrup will give you the most similar light and buttery flavour).

Why do you add oil to the chocolate topping?

Adding just a little mild vegetable or coconut oil to the chocolate layer makes the slice much easier to cut through without the chocolate cracking. It is optional but I find this is really helpful. Seemy tips for cutting slices perfectly.

Can I use skim or light condensed milk instead of full fat?

Using a full fat sweetened condensed milk, instead of skim or light, makes the slice set firmer, and you really do want a firm caramel filling for this slice.

Cutting the slice

Take the slice out of the fridge 30 minutes before cutting to allow the chocolate to soften slightly. Use a small serrated knife to cut through the chocolate layer and then through the base. Seemy tips for cutting slices perfectly.

How to ensure your caramel layer sets

You absolutely must, must,must cook the caramel layer until it's firm. If it's not firm, your caramel slice will end up in a runny mess!

Firstly, heat the ingredients on the stovetop or in the Thermomix on a low heat, stirring continuously for about 10 minutes until it's obviously thickenedand coats the back of a spoon, and then pour over the base.

Secondly, bake until its golden and bubbly and you can gently place a finger in the centre of the slice and it feels firm to the touch. If it'sbrowning too much in the oven, place a sheet of foil loosely over the topand continue cooking until firm.

Thirdly, allow the caramel filling to cool completely before you add the final layer of chocolate topping.

Storing

Store white chocolate caramel slice in an airtight container at room temperature (or in the fridge) for up to 5 days.

Freezing

Allow the slice to cool completely and then double wrap in plastic wrap or foil and freeze for up to 1 month. Allow to come to room temperature before consuming.

I absolutely love the comforting feeling of being in the kitchen and baking something from scratch that I know everyone will enjoy.

And lets face it, there's nothing better than food that's homemade with love!
