Naughty & Delicious Salted Caramel Millionaires Shortbread – Heavenly Treat that Everyone Adores!

I have obviously always adored anything caramel, especially anything salted caramel. This is obvious, just search caramel on my blog and you will find soooo many references to the heavenly creation.

My favourites being my No-Bake Salted Caramel Cheesecake, Salted Caramel Drip Cake, my Salted Caramel Cupcakes and my EVER popular Millionaires Shortbread – Back to Basics. However, this is definitely on par with all of these because HELLO? YUMMMMM.

I posted my first millionaires themed recipe ages ago in the form of my Millionaires Shortbread – it has always been so popular when I have posted it onto my social media pages, and when I have made it for my friends and family. Seriously, its always the traybake to make for a gathering!

When I posted my Salted Caramel Nut Slice recipe my readers were launched into the delicious world of nutty, salty and sweet – HEAVEN.

However, I decided that it was about time I posted my recipe for my Salted Caramel Millionaires Shortbread as I have had soooo many requests for it!

I used the same shortbread recipe that I used in my  Millionaires Shortbread, and the same caramel recipe as in my Salted Caramel Nut Slice, but I added the salt to the caramel itself this time.

The problem with such things as this is that you can’t taste test how salty it is as it is really really hot. Obviously. If you are nervous about how salty it will be then start with less, maybe two pinches of sea salt (See my notes below!) and you will be fine!

I decided to use a mix of chocolates on top of my shortbread this time because I love the mix of them, and its an easier way to decorate something without much effort. You can of course just use one type of chocolate, but it isn’t as pretty!

One thing I must say though is just using a tin of carnations caramel will NOT work. You MUST make the caramel for it to set, carnations caramel will just stay a sloppy mess – and its much easier to make a caramel than you think! Enjoy!

Ingredients

Shortbread

  • 200 g unsalted butter (room temperature)
  • 100 g caster sugar
  • 275 g plain flour

Salted Caramel

  • 200 g unsalted butter
  • 3 tbsp caster sugar
  • 4 tbsp golden syrup
  • 397 g condensed milk
  • 2-3 pinches sea salt

Topping

  • 200 g milk chocolate
  • 100 g dark chocolate

Instructions

Shortbread

  • Preheat your oven to 180C/160C Fan, and line a 9x9inch deep square tin with parchment paper.
  • Cream together the caster sugar and unsalted butter until smooth.
  • Mix in the plain flour until a dough is formed. It will be crumbly but the ingredients will be evenly dispersed!
  • Firmly press the mixture into the bottom of tin and bake in the oven for 20-25 minutes until pale golden on top!
  • Once baked, remove from the oven and leave to the side.

Salted Caramel

  • In a large saucepan pour the condensed milk, unsalted butter, caster sugar and golden syrup and melt on a medium heat till the sugar has dissolved – stir frequently to stop anything from catching.
  • Once the caster sugar has dissolved, turn the heat up high and let the mixture come to boiling point and boil for 5-7 minutes stiring constantly so that the mixture doesn't catch.
  • BE CAREFUL as the mixture is VERY hot and can burn you if it splashes back! The mixture will be ready when it has changed to a slightly darker golden colour, and has thickened to a soft fudge texture!
  • Crush your 2-3 pinches of sea salt into the salted caramel and mix in - pour the salted caramel onto the shortbread base and leave to completely set.

Topping

  • Once chilled, melt the milk and dark chocolate and pour over the caramel.
  • Swirl them together with the end of a skewer so it forms a pretty pattern. 
  • Chill the shortbread back in the fridge for another 1-2 hours until the chocolate has gone hard.
  • Chop your shortbread into the separate pieces and enjoy!

Notes

  • This will keep in an airtight container for at least 1 week, or you can freeze for up to 3 months – if they last that long!
  • If your caramel is rock solid when you remove it from the fridge, you have slightly over done it. Not to worry though, when you pour the chocolate on, leave it to set at room temperature rather than in the fridge and it should soften the caramel slightly.
  • If you struggle to cut your shortbread and tray bakes without the chocolate cracking on top, set it at room temperature rather than in the fridge and it'll be softer so therefore won't crack when you cut it!
  • Alternatively you can warm up a large sharp knife with boiling water and try cutting your slices using this!
  • I use Maldon Sea Salt as it tastes delicious and I like my caramel salty so I use the 3 pinches - I really really recommend using Sea Salt over ground fine salt as the taste is better and it's easier to use compared to the fine salt where you could easily add in far too much.

ENJOY!

    Hi I made this today and my family loved it,I wasn’t able to cut it into neat squares but the taste was delicious and totally worth the effort.

    Every time I make this, my caramel splits and goes grainy! Where am I going wrong?
    The butter leaks out of the caramel when I pour it onto the base.
    The caramel itself is always grainy not smooth despite me melting everything gently before boiling.

      If it’s splitting and the sugar has dissolved before hand correctly, it’s likely the heat is too much and it’s caused the caramel to split x

    Hi Jane, great recipe! I only have some trouble cutting through the shortbread when the millionaire shortbread is finished… It crumbles and bits of shortbread separate from the caramel… Any suggestion to have a clean cut?
    Thanks in advance!

      I usually use a knife that is larger than the size of the traybake so I can cut down in one go rather than having to cut several times. You also need a super sharp knife and make sure you compact down the shortbread ingredients well before baking x

    Made them with caramel & white chocolate the caramel split but fixed it with online tips & they taste amazing

    Hi, I’m making this for the first time and I live in France so the choice of ingredients are a little different. I have the choice between sweetened or non sweetened condensed milk, which one would you suggest? Thank you

    • Jane's Patisserie on April 11, 2024 at 12:28 pm

      In the UK our condensed milk is sweetened! x

    Can I make these with gluten free flour

    • Jane's Patisserie on January 30, 2023 at 11:57 am

      Hiya! Yes, this should be fine! Enjoy! x



  7. Zara on January 19, 2023 at 4:27 am

    Can I ask why you use the all in one method for the caramel here rather than doing the water and sugar starter like in your caramel sauce recipe? Are they produce different things? I’m just worried my caramel never made it that dark in colour even though I left it for a good few minutes longer than suggested?

    • Jane's Patisserie on January 30, 2023 at 11:22 am

      Hiya! Either way works, as long as it is the right consistency it should be fine! Take a look at my recipe videos on my social media channels for some more tips x



  8. Michelle on January 27, 2022 at 7:10 pm

    Hi Jane, I’m about to make these and I have realised I only have enough unsalted butter for the shortbread, so I would have to use salted butter in the caramel. Would this work? Could I use it instead of the pinches of sea salt?
    Thanks in advance 🙂

    • Jane's Patisserie on January 31, 2022 at 1:29 pm

      Hiya! Yes this should be absolutely fine! Hope this helps x



  9. Carlie on December 23, 2021 at 12:43 pm

    Ive just made these and how long do you leave them in the fridge once youve done the caramel ontop? I always follow your recipes when i bake, everyone loves them😬

    • Jane's Patisserie on December 30, 2021 at 10:15 am

      Hiya! I leave it in the fridge until the caramel is completely set. Hope this helps! x
