Recipe background
This slice goes by many different names: millionaires slice, millionaires shortbread, caramel shortbread, caramel squares, caramel slice and even Wellington squares. But no matter what you call it, this is hands-down the best slice recipe. It is unapologetically sweet and so so decadent.
I make this slice whenever we have a big fishing trip or big weekend hike as a sweet treat to look forward to. That is if it even makes it to the start of the trip!
How to make millionaires slice
This recipe is simple enough to follow, and is broken in to 3 main sections. The biscuit base, the caramel filling, and the chocolate top. My recipe is different (and arguably the best) because I only use dark chocolate on the top. This helps to cut some of the sweetness with the bitterness of the chocolate. I also crack some salt on top to add another dimension of flavour to compliment the chocolate and caramel. And lastly rather than shortbread base, I have constructed a perfect biscuity base that is unparalleled by other recipes that I have trialled.
Ingredients
For the base we just need flour, brown sugar and butter. The caramel filling is made with butter, brown sugar, vanilla extract, and sweetened condensed milk. And lastly the chocolate top is made with dark chocolate, small bit of oil, and a sprinkle of salt.
Tips and tricks for perfect millionaires slice
I promise this recipe is super easy, even though it has 3 parts. The chocolate step is basically just melting chocolate with a little oil, which is easy peasy. The base is mixing all the ingredients together, then pressing it in to the tin – also super simple. And the caramel filling, arguably the trickiest part – is just putting it all in the pot and letting it bubble away for 5minutes or until a dark rich caramel colour. The only advice is DO NOT STOP STIRRING the caramel, it loves to stick to the bottom of the pot, so make sure to keep mixing when there is any heat around. Thats it. You have got this!
