Millionaires Flapjacks!

A Soft & Chewy Flapjack, topped with an easy Homemade Caramel, and Swirled Chocolate makes DELICIOUS Millionaires Flapjacks!

So recently I went to one of my favourite local Tea Rooms (The Tenth Hole) and my boyfriend treated us to a piece of Millionaires Flapjack each. I will say now, he wasn’t actually a massive fan because he loves a classic Millionaires Shortbread, but I LOVED it. I had no idea that Millionaires Flapjack was even a thing! I WAS SO EXCITED.

Honestly, it was the best decision. I based the idea around my Honeycomb Flapjacks and Salted Caramel Millionaires Shortbread. However, as my standard flapjack recipes contain Honey, I wanted to change the flapjack mixture from using Honey, to using Golden Syrup as well so that there are fewer ingredients to buy and use as I tend to have golden syrup in my cupboard more often than I do honey.

Also, as the Flapjack I went for and liked best used Light Brown Sugar, I swapped my standard Caramel for an alternate one which I have also used many times. Swapping ingredients from each part made it easier and more straightforward! You can, of course, use honey in the flapjack if you prefer – they are a straight switch! 

I wanted to make sure that these were suitably delicious and addictive, and they are. I like my Flapjack to not be rock solid, but be chewy and delicious. The same with my caramel, not too hard otherwise it just hurts my teeth! The Chocolate is just an added bonus, and for show I used a mixture of Milk Chocolate and White Chocolate, swirled together all pretty like.

I genuinely question how I have never seen/heard of/eaten this delightful treat before, but I am so glad I have now. It makes a nice change to your regular Millionaires Shortbread, but I love both equally. I was never a massive fan of Flapjack as a child because in my mind it was healthy.. I realise now it’s not, but can be healthyish.. but my version, of course, is not. Sugar & Syrup play a delightful and necessary roll in my Flapjack and it makes it so scrumptious. If you want to try it with less sugar/syrup then go ahead, but it won’t bind as well or taste as deliciously sinful. ENJOY!

  • 175 g Unsalted Butter
  • 125 g Light Brown Sugar
  • 125 g Golden Syrup/Honey
  • 325 g Rolled Oats


  • 175 g Unsalted Butter
  • 175 g Light Brown Sugar
  • 397 g Condensed Milk (one tin)


  • 200 g Milk Chocolate
  • 100 g White Chocolate


  • Preheat your oven to 180C/160C Fan, and line a 9x9inch Deep Square Tin with Parchment Paper.
  • In a medium pan, put the Butter, Sugar and Syrup/Honey and melt on a low heat till smooth.
  • In a large bowl, pour the Rolled Oats and pour on the melted sugar/syrup/butter mixture and mix together. 
  • Firmly press the mixture into the bottom of tin and bake in the oven for 20-25 minutes until starting to brown around the edges!
  • Once baked, remove from the oven and leave to the side. In a large saucepan pour the condensed milk, butter and sugar and melt on a medium heat till 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 constantly for 3-4 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 flapjack base and leave to set. Either set it in the fridge for 1-2 hours to be quick, or room temperature for a not-so-chewy treat!
  • Once chilled, melt the chocolates and pour over the caramel – Swirl them together with the end of a cake skewer so it forms a pretty pattern. 
  • Chill the traybake back in the fridge for another 1-2 hours until the Chocolate has gone hard, or again at room temperature for a not-so-chewy treat and so its easier to cut**!
  • Chop your Millionaires Flapjacks into the separate pieces and enjoy!


  • This will keep in an airtight container for at least 1 week – if they last that long!
  • You can use the other caramel method from my Millionaires Shortbread if you prefer it!
  • If you 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 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 advise using a large sharp knife to cut it, and it should crack less.
  • You can add in a pinch or two of sea salt to your caramel to make Salted Millionaires Flapjacks!

    Every time I made millionaires shortbread, the caramel never set, after coming across your recipe. I gave it another go, SUCCESS!!! At last, and my husband is one happy man😂. Thank you for
    sharing X😊😊

    Hi can you use carnations caramel instead of the caramel ingredients you listed? Will this affect the flapjack at all or?

  • Ellen Evans

    Hi, I don’t have a 9×9” tin, only a 8×8” tin.
    Would you alter the amounts of the ingredients, or cook time, etc?
    I recently made the Bakewell blondies in it, they tasted incredible, but the middle was undercooked, not just gooey.
    I feared cooking for longer would have burnt the well risen edges.
    As I took it out it had that little wobble you describe.
    Thank you for any advice.

      Hey! Yes so the blondies would have struggled a bit more because of the increased depth! An 8″ square tin is about 1/5 smaller in volume, so it may be worth just reducing the recipe by 1/5th as well and it should be fine! x

    For some reason, every time I make flapjacks using the recipe above, I’m left with a pool of butter at the bottom of the tray. What am I doing wrong?

    Ps you have given me my confidence to bake again because your recipes are easy to follow and turn out so well. So thank you 😊

      Genuinely, I have no idea! I’ve never experienced this! Unless you are accidentally using too much, or your oven is too hot to frying the butter slightly – but I’ve never known anything like that to happen.

    If I just wanted to do flapjacks would the recipe still be ok to use without the caramel

    Is there a reason you use a different caramel recipe in the newer millionaire bakes? Just out of curiosity.


    • Jane's Patisserie

      I’ve explained in the post why this caramel is different – its the only recipe to use this type of caramel, all my others use the other type.

      Hey..just a quick question.. my flapjack sort of crumbled when I cut it? Its firm on the top but softer inside…I cooked it for about 45mins…any advice plz???

    • Jane's Patisserie

      You’re only supposed to bake it for 20-25 minutes as stated in the recipe – I’ve never ever had an issue with the flapjacks, so if you used the wrong ingredient, over baked it, or the oven was the wrong temperature then you’d have a problem.

    I’ve made these and they look fab, it’s just setting in the fridge at the minute. Only thing is, the Caramel got lots of little black bits in. Now I know it’s because the caramel caught but I stirred it constantly… any tips? Should it be a cast iron bottom pan?

    • Jane's Patisserie
      May 23, 2018 at 8:14 pm

      I use regular non-stick pans, but maybe try and Lower the temperature ever so slightly and do it for a bit longer so it has less chance of catching? Also try and use a spatula for example so that the bottom gets properly scraped each time you stir as well as the corners! X

    Jane I made these at the weekend, and brought them to work and people have not stopped going on about them!
    They were so delicious and I would recommend anyone to try baking these, they are easy to make and look so professional with the swirled chocolate on top.
    Absolutely fab <3

    I think I murdered your recipe, it was a crime scene! The flapjack is great but I tired to make the caramel and the butter kind of sat on top. Help me Obi One xx

      Oh no! Sounds like it split a little. Did it set okay?

      You know I tasted it and thought it tasted delicious so I drained off the butter, spread it over the flapjacks and it set up just fine. It ended up tasting delicious and half of it is already gone! My family love your recipes, I sometimes have a hard time getting Cadbury products (stupid Hershey banned them in the US) thank you so much for being so creative! 💜

    Can I freeze the flapjack base ahead of time then defrost and do caramel and chocolate layers when needed?

  • Tom

    Thanks for these! They have gone down a treat! Made one with banana layer as well, so became Millionaire banoffee flapjack , and it was amazing. I say was, because it’s all gone!

    I’ve made these twice now and they work perfectly each time. Topped today’s with mini eggs and creme eggs as an extra treat seeing as it’s neatly Easter!

      I also use the base when I’m just making flapjacks as it’s so nice ?

    A now ex-colleague of mine ‘invented’ millionaire’s flapjacks several years ago. He came in with a huge box of them with great shiny, happy eyes and distributed them around. He was very proud of himself…

    These look very good 😉
