Macadamia Caramel Slice

I’m not the owner of this recipe. I first tasted this creation a few years ago, when my sister brought back samples from various parties at her office. The owner of this delightful recipe was a woman who was a coeliac, and she made the gluten-free version of this by merely substituting the plain flour for gluten-free plain flour. She readily agreed to pass on the recipe to my sister, who passed it on to me, who has passed it on to a number of other friends since, and now to you. As recipes should be spread. I don’t believe in the ‘keeping it to yourself’ nonsense – because then there’s a whole lot of pressure for you to make it and make nothing else the next time you come together for a food fest, as it has then become your ‘signature’.

Maybe some like to have a signature (probably because they can’t bake anything else as well). But I enjoy variety.

And with this gorgeous slice with its brownie-like texture and the rich flavour of the macadamia nuts – you will be an instant hit at any picnic, office, or gathering of family or friends you care to name.

You will need:

For the base:

  • 100g white melting chooclate;
  • 125g butter, softened;
  • 90g icing sugar, sifted;
  • 60g macadamia nuts, roasted and chopped finely;
  • 200g plain flour.

For the topping:

  • 395g can sweetened condensed milk (Nestle – and don’t even bother if you’re going to use the 98% fat free stuff);
  • 200g white melting chocolate;
  • 2 large eggs;
  • 2 tablespoons plain flour;
  • 90g shortbread biscuits chopped (I used Arnotts Scotch Fingers);
  • 200g roasted macadamia nuts, roughly chopped;
  • 60g roasted macadamia nuts (whole, extra).


Preheat the oven to 180 degrees Celcius. If you bought natural nuts, roast the entire 320g on a flat oven tray until golden, before putting aside to cool. Butter an inch-high 30cmx25cm slice pan and line it with baking paper.

Melt the white chocolate over a double saucepan before adding it to a mixer with the softened butter, sifted icing sugar, chopped macadamia nuts and plain flour. You can use either a food processor or a hand-mixer for this. Mix on low speed until all of the ingredients are combined, then press the mixture evenly into the prepared tin.

Bake the base in the oven for 18 minutes before setting aside to cool.


Chop (not crush) your shortbread biscuits.

Reduce the oven heat to 160 degrees Celcius. In a medium saucepan, heat the condensed milk and white chocolate together on a low heat, stirring just until the chocolate has melted. Watch it carefully as condensed milk has a tendency to burn on the bottom very quickly. Whisk in the eggs and flour, before adding the shortbread biscuit pieces and chopped macadamia nuts, and mix gently.

Spread this mixture over the base, before sprinkling over the extra macadamia nuts.

Bake at 160 degrees for 40 minutes. Remove from oven and cool at room temperature before moving it to the refrigerator to cool further.

Remove and slice. Use a ruler if you utterly fail at cutting in a straight line, like me. I cut 5cmx5cm squares, amounting in 30 squares in total.

Absolutely delicious.

Have a great week, lovelies 🙂 Make sure you don’t over-do it and exhaust yourself this holiday season xx

    That looks great! I love anything with macadamia nuts; they go so well with caramel.

    1. One of food’s many best matches! 🙂

    They look fanatastic. I’m such a sucker for white chocolate so these would definitely work a treat for me 😉

    1. The original recipe actually uses milk but I wanted them blonde so used white chocolate. It’s not overly-sweet at all – the natural saltiness of the macadamia balances it right out!

    Does it matter if the Macadamias are salted?? I can only find Salted Macadamias in Coles =/

    1. Hello Winnie – salted macadamias will just make the dessert too salty. Any regular Coles should have it, so ask someone there for help 🙂

    I just made this slice and it was absolutely delicious! Thank you so much for a fantastic recipe. I made a half batch and used a rectangular fluted pie tin and it looked so pretty. It was so amazing I reckon you could even serve it as a dessert, warm with a scoop of ice cream!

    1. Thanks for the feedback, I’m thrilled to hear it turned out wonderfully! Macadamias can be a bit pricey but the finished slice is really nothing short of amazing. Happy Baking! x
