Caramel slices are so beloved and omnipresent in Australia, I think it might be borderline illegal to call yourself a bakery if you don't sell them. If you've never had the pleasure of classic caramel slice, it's a bit like the Twix bar of your dreams. With its crunchy coconut cookie base and crackly chocolate topping surrounding a layer of rich and gooey caramel, this is pretty close to treat nirvana.
What distinguishes caramel slice from its 1970s origins in the Australian Women's Weekly as caramel shortbread squares or the fantastically named millionaire's shortbread (good job by you, Scotland!) is the base. It's more biscuit than shortbread, so you get more of a crunch to contrast with the textures of the other layers. However, what I think makes a caramel slice truly Strayan is the addition of coconut in the base - who else loves dessicated coconut in its treats as much as Aussies? Not only does it really add to the flavour profile, it also lends an extra bit of chewiness.
For the caramel layer, we'll take a languid, lazy Sunday approach to get a smooth, velvety and rich result. Just get your butter/condensed milk combo going low and slow and keep the stirring consistent and frequent so it doesn't stick to the bottom of the pan as it thickens. Baking your caramel is your insurance policy for a firm layer, otherwise you'll run the risk of it squidging out the sides when you cut into your slice. If you're unable to source golden syrup, maple will do just fine.
Milk chocolate is most commonly used for the topping, however dark chocolate does cut through the overall sweetness of the other layers. Adding the oil will make the chocolate slightly softer when it sets so the topping won't crack when you slice into it. When you pour the melted chocolate over the caramel layer, it will set pretty quickly, so make sure you have a spatula at the ready to spread it out.
Leave your slice out of the fridge for about 15 minutes before serving so you can cut it up without too much trouble. A warm knife will also help out - pour some boiling water over it and dry with a towel before wielding. If you want to take your slice to another decadent level, leave it out a little bit longer so the chocolate ever-so-slightly starts to melt. That is the business right there.
