A complete ‘how-to’ guide on how to make millionaires shortbread! A homemade shortbread base, homemade caramel filling, and a chocolate topping. 

So it’s been a while since I posted my last ‘back to basics’ post – my last being my no-bake lemon cheesecake post in May last year. And after the success of my youtube video on how to make Millionaires Shortbread, I thought I’d do the blog post for it too

I have obviously made quite a few millionaires shortbread recipes already, but I thought I would cover it down to every last detail. Basically, completely dumb it down into the ground so that if you are scared to make it, you won’t be any more

Shortbread

For the shortbread, it really is quite basic – you can do it by hand, or in a food processor, or in a stand mixer, or with an electric hand mixer. You just want to mix the sugar and butter together until creamy, and then add the flour and combined until a dough is formed.

If you are doing this by hand, you can add all three ingredients together, making sure the butter is cold and cubed, and rub the mixture together with the tips of your fingers until it creates a bread crumb texture. Then, you effectively knead it together to form the dough.

I always tend to use classic unsalted block butter but you can use a baking spread for this bit if you prefer. I just prefer the taste when it comes to real butter. When using a mixer to make it, you add the butter and sugar together, beat until creamy, and then add in the flour and combine.

Baking

Press the shortbread into a lined tin – I use a 9″ square tin – and make sure it’s even. I use a 9″ square tin as it’s the ultimate depth for the number of ingredients I use! If you use a smaller tin, it will take longer to bake – if you use a larger tin, you might have issues as the shortbread really isn’t that thick. 

You bake it in the oven at 160ºc in a fan oven, 180ºc regular, and bake until it’s starting to golden. When it’s starting to golden, and it’s been in for at least 20-25 minutes, you’ll know it’s baked through.

Caramel

For the caramel, you REALLY have to work on it. You can’t cheat and use a tin of carnations caramel and stick it on top as it doesn’t set. You can’t really skip the steps, as it really is a caramel. I don’t often make my caramels from complete scratch as many of my readers prefer the easier versions, and I get that, but for millionaires shortbread? You do.

You have to make sure to stir the caramel a lot to prevent it from catching and burning. I use a medium level of heat, and a larger pan so its easier to stir. You have to be careful as it obviously does get VERY hot, but it’s worth it. It is delicious and heavenly.

I use a gas hob because I much much prefer it for making caramel. I get that not everyone has gas though – some have electric, some have induction – but on my gas hob, I usually use between level 7 and 6 of strength on a medium-size ring, on my 9 level hob. 

You want to use actual unsalted butter – as it creates the best caramel. I use golden syrup, because it creates the most wonderful caramel, as I explain in my video. If you can’t access golden syrup, however – I suggest using the caramel from this recipe post instead

Caramel problems

I’ve received comments about people getting little dark coloured lumps in the caramel, and this is down to catching. Once it’s caught, there isn’t really anything you can do, other than preventing it from getting any more burnt. 

If your caramel is grainy by the end, that’s because you didn’t dissolve the sugar properly at the beginning. You really want to slowly melt the condensed milk, golden syrup, sugar and butter together before it starts to boil – then it will be lovely and smooth. 

The timing is something I can’t really narrow down on. It takes between 5-7 minutes to boil. This can vary depending on the type of stove you use, the brand of ingredients, the pan you use, and so on. I don’t boil the caramel to temperature, and I never have. 

Once you have poured your caramel onto your shortbread, you have to leave it to set. I usually do this in the fridge because it’s quicker. Once it’s set, you add the chocolate

Topping

The chocolate part is quite straight forward – you just want to melt it, and cover the top, and let it set as well. I used a mix of milk and white chocolate, but you can use whatever you fancy! All milk, all dark, all white.. or all three! Any flavour you fancy too. It’s epic and easy.

I find it easier to melt my chocolate in a microwave, but this is something I have done many times. I know my microwave in and out, but if you don’t have on, you can melt your chocolate in a double boiler which is a bowl, over a pan of simmering water. 

Of course, once you have decorated your millionaires with the chocolate, you need to leave it to set. I find it easier to set it in the fridge as it’s much quicker, but that is optional. If you set it at room temperature, then it will take longer but it will be easier to portion. 

Portion

So… once you’ve reached the end of making it, you enjoy it. However, cutting it up can be an issue for some. As I used a 9″ square tin, I use a 26cm knife to cut it. This is because the knife is larger than the traybake, and it makes it a hell of a lot easier. I tend to make sure it’s straight, score the chocolate ever so slightly, and then just cut straight down. 

You can try a few different other things, such as scoring the chocolate when it’s not fully set yet, or heating the knife before cutting – but honestly, I just find using a large and sharp knife and going straight down is the best method for me. Some people even try cutting the traybake upside down so that the chocolate is the last bit you cut through. 

Top tips 

If you find once your millionaires shortbread is finished, that the caramel is rock solid and more like toffee, you overdid it slightly on the boiling. It’s best to keep and store it at room temperature from now on, so it’s at least not fridge cold hard. If your caramel is too soft, you didn’t do it for long enough, so should definitely be kept in the fridge.

You want to use a good quality pan if you can, as some pans have a very thin base. Basically, if the base is too thin, you might burn the caramel. So if you are worried, take the temperature down a notch and do it for a little longer instead to prevent any catching!

You also want to use a flat bottomed spatula, like these ones. Using a spatula with a sharp corner means you can really scrape the caramel, and prevent it from catching in the corners!

  • I use this 9″ square tin
  • The millionaires shortbread will last for 7 days at room temperature, or in the fridge 
  • The millionaires shortbread can freeze for 3+ months

Ingredients

Shortbread Ingredients

  • 200 g unsalted butter
  • 100 g caster sugar
  • 300 g plain flour **

Caramel Ingredients

  • 200 g unsalted butter
  • 3 tbsp caster sugar
  • 4 tbsp golden syrup
  • 397 g condensed milk (one tin)

Decoration

  • 200 g milk chocolate
  • 100 g white chocolate

Instructions

  • Preheat your oven to 180ºc/160ºc fan, and line a 9x9inch deep square tin with parchment paper.
  • Cream together the sugar and butter in a stand mixer with the paddle attachment until smooth – mix in the 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. In a large saucepan pour the condensed milk, butter, sugar, and golden syrup and melt on a medium heat until the sugar has dissolved – stir frequently to stop anything from catching.
  • Once the 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!
  • Pour the caramel onto the shortbread base and leave to set for an hour in the fridge.
  • Once set, melt the milk chocolate and pour over the caramel – melt the white chocolate and pour over too - swirl it into the milk chocolate with the end of a cake 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 – if they last that long
  • If you can't access golden syrup, you can give corn syrup or honey or similar a go, but I have not tested these as much. Alternatively, you can use my millionaires flapjacks caramel
  • 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
  • I recommend using a 9" square tin like this one
  • I also recommend using a spatula like these to prevent any catching
  • And if you are wondering - this is the golden syrup I use
  • ** recipe updated to be 300g instead of 275g plain flour for ease of using a 1:2:3 ratio with sugar, butter and flour  - both quantities work well so continue to use 275g if you prefer it. 

ENJOY!

    If I need to make these in a hurry, could i leave the caramel and chocolate layers to set in the freezer. If so, how much should i shorten the time down to?

    • Jane's Patisserie on July 22, 2021 at 1:31 pm

      It depends – it may make it harder to portion as the caramel will be colder – but I would say it van reduce the time by half maybe?! x

    Hi. I made this a few weeks ago and it turned out almost perfectly.

    The trouble I had was when I was getting the whole slab out of the tin tin to slice them. I always use softened butter to grease the tins before lining with parchment. I think that butter may have solidified when I chilled the individual layers and the whole thing got jammed in the tin. Thankfully I managed it in the end.

    Am I just greasing with too much butter? I want the parchment to stick but not get stuck!

    • Jane's Patisserie on July 20, 2021 at 2:06 pm

      I don’t generally stick mine down that much, so yes that could have been it – especially fridge cold!

    Hi Jane!! I have made this recipe a fair few times, but my Shortbread always seems really crumbly, any idea why?? I make it by hand as I don’t have a stand mixer, could this have anything to do with it??
    Thank you xx

    • Jane's Patisserie on July 21, 2021 at 8:38 pm

      Yes definitely – as long as it presses in and bakes well it should be fine as shortbread should be a little crumbly!

    Your site is fast becoming my go to place for all things baking. Definitely the best millionaire shortbread I’ve ever made. I used dark as well as milk chocolate but that’s down to personal taste. Big endorsement from my four year old, apparently they’re the best things she’s EVER eaten!

    Hi Jane,

    Ive just taken the caramel mix off the heat and when I taste tested a bit, it tasted bitty, like there was wee bits in it. Is this normal?

    Kara

    • Jane's Patisserie on June 10, 2021 at 12:31 pm

      Hello, no this isn’t normal it could have split and/or burnt slightly- watch my youtube video on this it may help xx



    • Kara on June 10, 2021 at 4:57 pm

      Hi Jane,

      Once set overnight they taste AMAZING and no bits left in the caramel/fudge layer. I think it may have been a few burnt bits. Thanks for your reply! Xx

    Hi Jane, do you melt your chocolate in the microwave and if so how long for and do you add any oil/butter.
    Thanks
    Sharon

    • Jane's Patisserie on May 19, 2021 at 1:55 pm

      Hello! Yes I do but how long depends on your microwave as the power in each microwave is different. You only add something if the recipe tells you too xx

    I have tried lots of different recipes for millionaires shortbread but this is by far the best. I’ve made it at least 4 times. I have altered the recipie a bit for my liking. I do 1 1/2 times the shortbread and I use brown sugar for the caramel since it gives it a darker colour. I also use 50% dark chocolate and 50% milk chocolate melted together for the top because I think it goes better with the sweetness of the caramel. anyone who I’ve made this for has loved it and I always get asked to make it again. so thank you for the amazing recipie

    These were delicious and loved by all who tried them.

    I thought I had ruined it when I saw little lumps of burnt bits in the caramel. It wasn’t a problem though i just need to keep the heat lower next time.

    Delicious, thank you.

    • Jane's Patisserie on May 8, 2021 at 2:16 pm

      I am so pleased you loved them!xx



  14. Tamsin on May 5, 2021 at 11:08 am

    These look amazing! Would they freeze well if I made a big batch?
