A deliciously soft and chewy flapjack topped with a homemade caramel and swirled chocolate – this millionaires flapjack is scrumptious!
Millionaires
As we all know, I am quite the fan of a millionaires shortbread. Luckily for me, I have made and eaten countless of these over the years, and I really do not get bored of them. After all this time, I do think a homemade one is the best of the best, but even the little bite versions you can buy at a supermarket get me every time.
I have my classic millionaires shortbread recipe as part of my back to basics series, and I love it. I have variations for occasions such as chocolate orange millionaires, or even my mini egg millionaires for easter, and I just can’t get enough of them.
A buttery delicious shortbread, topped with a homemade caramel, topped with chocolate. You can make it as basic as you want, but it’s still tasty. I would ALWAYS recommend making your own caramel as well, because a tinned/jar version simply does not set, and it tastes a lot more sickly in a bake like this.
Millionaires flapjacks
Years ago I went to one of my local favourite tea rooms, and they had a millionaires flapjack recipe. This is just something that blew my mind in the moment as I just hadn’t considered using another base at the time. This bake is why I wrote this recipe, as it gave me so many more ideas.
I have since done other versions with different bases as well, such as my millionaires cookie bars, millionaires brownies and millionaires blondies. Basically, any traybake you can think of, topped with caramel and some chocolate and I am extremely interested.
The texture of a flapjack for me is chewy, tasty but not so rock solid it breaks your teeth. You can add other ingredients if you want to a flapjack, but for these to make sure it all works together I went for quite a simple flapjack.
Flapjacks
Flapjacks appear to be one of those bakes, that sometimes just don’t work for people. They are an extremely simple mix of ingredients, but the ingredients that you end up using are quite important. I have simplified this recipe as much as I can to make it as accessible as I can.
- Butter – I’ve always said that using a block butter is best for a flapjack, as sometimes the additional ingredients in a spread can make the mixture not bake properly, become sloppy or oily.
- Sugar – Usually, I use light brown soft sugar as I use it in so many bakes, and it’s also used in the caramel in this particular recipe. You can use caster sugar if you want, but personally I would switch it for a muscovado sugar instead.
- Syrup – Typically, I use golden syrup, or honey in my flapjacks. You can use either, or a mixture (depends what you have in the cupboard). As explained later in this recipe, I made the caramel differently to normal in case you don’t have golden syrup where you live, so you can easily use honey for this part.
- Oats – I recommend using rolled oats, the larger ones. Often I find flapjacks can be a little broken or sloppy if you use a small oat, quick oat, or some porridge oats.
Caramel
So, I will explain it here so you all don’t panic – this caramel is different to the other caramel recipe I often use in my millionaires shortbread. There is a reason, and there is nothing wrong with the other one – it’s simply to show a different sort of caramel that doesn’t use golden syrup.
In the UK we have golden syrup readily available in most shops, but it’s not a common ingredient across the world. I wanted to post a simple three ingredient version of a caramel to show a different method should you wish to use it – and this is it. It’s easy, and delicious still.
- Butter – again, I will say block butter is best for a caramel compared to a spread or margarine, because the block butter is much more pure and shouldn’t split your caramel.
- Sugar – I use light brown soft sugar because I want it to be the same as the flapjacks, but it’s also what gives the caramel it’s delicious flavour and colour.
- Condensed milk – in the UK our condensed milk is usually already sweetened, so I use one tin of that. You want to use the classic full-sugar and full-fat version for best results.
I will say again, please make your own caramel. If you use a tinned or ready made one, they just don’t set the same way and don’t taste nearly as nice in a bake like this in my opinion.
Chocolate
When it comes to the chocolate of a bake like this, you can kind of do what you want. You don’t even have to top the bake with chocolate if you want, or you can do something different such as top it with nuts and a drizzle of chocolate like in my nut slice recipe.
I went for a milk chocolate base, and then added in some white chocolate and swirled this through. I tend to melt my chocolate in the microwave as I find it easiest, but if you don’t have a microwave you can use bowls, over a pan of gently simmering water (making sure to get no water in the chocolate), swirl the chocolate through with a skewer.
Tips and Tricks
- Recipe post updated April 2025 – no changes to the recipe
- This will keep in an airtight container for at least 1 week
- They can freeze for 3+ months
- 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.
- You can add in a pinch or two of sea salt to your caramel to make Salted Millionaires Flapjacks!
Millionaires Flapjacks!
Ingredients
Flapjacks
- 175 g unsalted butter
- 125 g light brown sugar
- 125 g golden syrup/honey
- 325 g rolled oats
Caramel
- 175 g unsalted butter
- 175 g light brown sugar
- 397 g condensed milk (one tin)
Topping
- 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.
- In a medium pan, add 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 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 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 up the millionaires flapjacks into the separate pieces and enjoy

If I just wanted to do flapjacks would the recipe still be ok to use without the caramel
Yes!
Is there a reason you use a different caramel recipe in the newer millionaire bakes? Just out of curiosity.
Thanks
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.
Would I be able to freeze these once they are fully made up? X
Yes you can! x
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???
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?
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
Ahh thats amazing!! Thank you so much! x
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?
Yep!
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!
Ohh I am so glad! That sounds delicious as well! ❤️
I also use the base when I’m just making flapjacks as it’s so nice ?
These look excellent and easy to make. I am looking forward to updating a few recipes for things like pot luck at the office and church. Thanks for the inspiration.
Ah thank you!
My sons favourite

Hahaha I don’t blame you ? Hehe thanks!
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 😉
