I Finally Nailed Millionaire’s Shortbread

Millionaire’s shortbread, also known as a caramel slice or caramel shortbread, is something that I love to eat. When you happen upon a good one, usually from a table at a school fair who’s Grandma has made, it’s pretty unbeatable by anything else. However, for me, making it has never really worked out.

That was until this week when I decided to give it another go. The key, it would seem, is in the caramel and getting that just right so that it’s not too hard, or worse, too soft. So I looked at a number of recipes, read the methods and settled on this receipe from Jane’s Patissarie, although I did skip using the Biscof spread in the topping. Credit to Jane here, this is insanely good!

The first thing to note is that I made a “quickie” receipe. Rather than making a shortbread base from scratch the base in this millionair’s shortbread is made using bisuits and melted butter, like in a cheesecake. I decided that using digestives was borning so I used the Aldi copies of the Lotus Biscof caramel biscuits to add an extra dimension to the finished slices.



  • 500g caramel “Biscof-style” biscuits
  • 185g melted butter


  • 1 397g can of condensed milk
  • 200g butter
  • 3 tbsp caster sugar
  • 3 tbsp golden syrup


  • 300g milk chocolate
  • 3 caramel “Biscof-style” biscuits – crumbled
