If you love Millionaire shortbread than you have to try Billionaire shortbread! This popular shortbread bake is placed in a whole new league with the addition of salted caramel. Once you try it, you’ll have to agree it’s one fantastic treat!
I’ll be honest, before moving to England, I never heard of Billionaire Shortbread (or millionaire shortbread for that matter), but after my first taste, I was won over and it’s still one of my very favorite things in the world!
I’ll never forget where I was the first time I tried Billionaire shortbread. It was on the train going to London for the very first time. My husband took me to a fantastic sandwich shop that’s near our local train station and that’s when I noticed them. The thick layer of shortbread followed by the caramel and chocolate was too much to resist! We added it to our order and I ate it on the train. I’ve been hooked ever since!
To make them, you start with the shortbread base.
Followed by making the caramel and pouring it over the shortbread to cool and set.
Once the caramel sets, you melt the chocolate (for more information on how to properly melt chocolate, see my guide on How to Melt Chocolate).
Carefully smooth the chocolate over the caramel.
Leave to set completely before cutting or you’ll end up with the same beautiful, gooey mess I did!
Serve and enjoy every last bite.
