This the Boutique Bake version of Millionaire Shortbread/Caramel Slices, which has a gorgeous hazelnut biscuit base. The flavour of nuts, caramel and chocolate is an absolute classic and seriously delicious! This recipe involves 3 different layers so isn't the quickest to whip up, but it is definitely worth the effort, I promise!
The topping involves both milk and white chocolate melted, to make a lovely swirly pattern, so this is a serious show stopper!
If you would like to make this nut free, that is absolutely fine, the details are included below.
