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!

    I’ve not been able to get hold of condensed milk but I do have a tin of evaporated milk. Can I substitute that for condensed milk?

    • Jane's Patisserie on May 6, 2020 at 5:18 pm

      Unfortunately not – no. They are very different products. I’ve read you can make your own condensed milk from evaporated milk though so it’s worth a google.

    I made these for the first time last week and I can’t believe how good they came out and they tasted amazing! Will definitely be making these again!

  3. Jordan Lunnon on August 27, 2019 at 6:13 pm

    These are sooo amazing, i make my first batch a week ago and i’ve already bought ingredients for a third because people love them so much! Thank you!

  4. Abbie on August 16, 2019 at 7:50 am

    Is there a temperature of when the caramel is just ready? I have made this recipe so many times and I still always have variations on the caramel as I get nervous it will be overdone so take it off and it’s not ready enough and sometimes I get it spot on

    Thank you

    • Jane's Patisserie on August 16, 2019 at 4:59 pm

      No, this works by time x



    • Jenny on February 26, 2022 at 9:14 pm

      Hi I’ve just made these and my caramel has set like toffee it’s so hard
      should I start again as I think it will break my teeth.



    • Jane's Patisserie on March 6, 2022 at 1:30 pm

      Yes, if it has been boiled for too long you can’t really recover it unfortunately!



  5. Victoria on July 3, 2019 at 7:43 pm

    My caramel looked like the butter split as there’s was a thin layer on top. What did I do wrong?

    • Jane's Patisserie on July 3, 2019 at 10:04 pm

      You may have boiled it for a smidge too long or slightly too hot so it split x



  6. Jacob Hardman on June 15, 2019 at 8:27 pm

    Could I substitute the unsalted butter for stork? Would it make a world of difference? This also relates to your other brownie recipes like triple chocolate.

    • Jane's Patisserie on June 16, 2019 at 8:48 pm

      For shortbread I always recommend using actual butter – otherwise it could taste different as they’re are only three ingredients. Other traybakes you can use stork, but I naturally use actual butter again!



  7. Amanda Soar on May 31, 2019 at 10:59 am

    Hi Jane really want to try this recipe but I only have a 8in deep square tin , would it work??

    • Jane's Patisserie on May 31, 2019 at 11:00 am

      It would, but it would just be very very deep! The shortbread may take a bit longer to bake as well x



  8. Francesca Lobban on November 8, 2018 at 10:54 pm

    Hi Jane, I just tried to make this, but the minute any heat touched the milk and butter/sugar, it burnt, I didn’t get to the boiling stage and I stirred it constantly, but it all burnt. What did I do wrong? 🙁 any ideas, I had to throw it all away…thank you for you help. x

    • Jane's Patisserie on November 9, 2018 at 9:34 am

      You have to put the condensed milk, sugar, butter and syrup into the pan and then heat it slowly. If it was already burning, the pan was far too hot. It should take quite a while to melt the butter/dissolve the sugar into the mix on a medium heat, so it just sounds like it was already too hot before it started x



  9. Anna Chilvers on September 16, 2018 at 6:25 pm

    I’ve just made these and they are delicious! Do you think they would freeze ok?

  10. Kirsty on March 4, 2018 at 3:28 pm

    Hi Jane.
    I’ve just made this, and it’s just setting. I’m scared to cut it! Have you ever tried using a hot knife? Would that make it easier or is it a bad idea?

    • Jane's Patisserie on March 4, 2018 at 8:13 pm

      I haven’t personally tried that as I usually just use a very large sharp knife, but I’m sure a hot one would work!



    • Kirsty on March 7, 2018 at 2:29 pm

      Well, i tried the hot knife and it worked, but it kinda smeared the lovely layers at the side. Excellent recipe though! Everyone loved it. I’ve just made your Rocky road…. I’m sharpening my knife for this one 😁
      Thanks Jane x



  11. Elena Hancock on February 27, 2018 at 6:12 pm

    Hi, I want to make this but I only have a tin of the carnation caramel not the condensed milk. Would that be alright to use that? And to thicken it would it be best to put it in a pan and reduce it down?

    • Jane's Patisserie on February 28, 2018 at 9:04 am

      Hiya – I’m not sure that would work as using the condensed milk and the other ingredients creates a setting caramel, heating the carnation caramel might just loosen it somewhat.



  12. Pauline on February 12, 2018 at 7:52 pm

    Hello. Do you melt the chocolate separately and pour on top separately and then swirl with the skewer?

  13. Amy on October 17, 2017 at 1:08 pm

    I’ve just made this and it looks delicious! I’m not sure I can wait for the chocolate to set before I tuck in!
    Thank you for another fabulous recipe

  14. victoria on September 9, 2016 at 8:40 pm

    I’ve made the nutty one and its delicious. I’m going to make this one next. How much salt roughly in teaspoons would you use and is it the salt you get in the grinder please. thanks for sharing your recipes xx

    • Jane's Patisserie on September 10, 2016 at 1:19 pm

      Hiya, I used pinches of salt in this recipe, and yes that sort of salt would be correct! xx



  15. Lauren Victoria on May 13, 2016 at 12:09 pm
