ty Biscoff biscuit base, homemade caramel filling, and a Biscoff chocolate topping… A Biscoff millionaires traybake!
This recipe is a popular, yet easy no-bake traybake. I have made it countless times over the years, and people always come back for more because the Biscoff obsession is real.
Biscoff millionaires traybake
Oh hey there, a new Biscoff related recipe that I know you are all going to adore and LOVE! Why would you not love it?! Biscoff biscuits, caramel, and Biscoff spread all in one delicious combination of heavenly bites. Is it too far to say I would happily eat the entire traybake? No, probably not.
So, who can honestly say no to a new millionaires shortbread style recipe? Certainly not me. I will say from the off, so as to stop any pedantic people… no, it’s not actually shortbread, but its a type of traybake. If you say millionaires shortbread, people get the idea, and when you add Biscoff on top of that, people automatically go ‘oooooh. I had endless requests for this as a recipe so I thought I would oblige whilst everyone is still on the Biscoff hype.
Recipe inspiration
This particular beauty is heavily inspired by my Malteser millionaires shortbread because when flavouring a millionaires, you can have fun. It is essentially the exact same thing, but swap all Malteser related goodies out for Biscoff.
Biscoff is one of my most popular flavours in the country. It’s a sweet yet spicy biscuit in a way, with the caramelised taste of wonder. The spread is even better. If you are a fan, I’d recommend dipping a lotus biscuit into the spread and devouring just that – however, when added into bakes, it’s elevated even more.
My Biscoff cheesecake and my Biscoff cake recipe have always been super amazingly popular on my website, thanks to Zoella making them a while ago. Some people have still yet to ever try the wonders of Biscoff, and you are 100% missing out if you haven’t tried it yet yourself. Some people do put their noses up at the flavour, but if you don’t like it, that’s fine… doesn’t mean someone else can’t enjoy it.
Biscuit Base
So, there is quite a lot of biscuit in this recipe. The reason I use 500g of biscuits in this recipe is that a 9″ square is equivalent to a 10″ round recipe, and that’s pretty darn big and you basically need enough biscuit to make the same depth you would get from shortbread, but with biscuits and butter. You can use less if you wish, but as you may have noticed from other recipes such as my Biscoff cheesecake, I love a deep biscuit base.
I blitz the biscuits to a fine crumb, and then add in the melted butter. I do find that Biscoff biscuits do need less butter than other biscuits, which is why the recipe has less. However, as it’s a fine crumb base, you really do need the biscuits to be a fine crumb before adding in the biscuits, and then you really need to press down firmly to make the base stick together. I add the biscuits to the base of a 9″ square baking tin that I have lined on the base and sides so that the traybake doesn’t stick.
Sometimes people can struggle with the biscuits base falling apart when cutting the finished traybake, and this is usually caused by the base not being fine enough, not pressed down far enough, or just people sawing at the bake to cut it. If you are worried, you can add 215g butter instead of 185g as the little extra butter will help.
Caramel
My salted caramel millionaires shortbread has been a classic from the start, and I love to try new things. Millionaires traybakes are basically biscuit, caramel, and chocolate. As you can see from my various millionaires related posts, I am a big fan of it and experimenting with the idea. How can you not like the combination of biscuit, caramel and chocolate. However, when I post my millionaires, the caramel is often the same because it works so well.
The mixture of condensed milk, sugar, golden syrup and butter is my favourite caramel – and I love it. You need to add the ingredients to a pan and melt the ingredients in the pan on low until all of the butter has melted, and the sugar has dissolved. Once the ingredients are ready, you then need to turn the heat up to a rolling boil and stir constantly for 5-7 minutes until you reach a golden colour.
Tips for a good caramel – make sure to use a flat bottomed spatula so that you scrape all of the bottom of the pan – if you don’t, you may get little flecks in your caramel. It’s also best, if you can, to use a heavy based saucepan as cheaper or older pans can transfer the heat differently and may be hotter. Check out my YouTube video on my classic millionaires shortbread, which you can watch here – and this may help for the caramel.
I pour the caramel onto the prepped biscuit base, and let it sit for an hour or so before adding the chocolate. I’ll often do this at room temperature as it will set enough during the entire process, you just want the caramel to have cooled slightly.
Chocolate
The chocolate layer is slightly different compared to some of my other millionaires bakes, as I really wanted it to be as Biscoff like as possible, with elements of the classic traybake. Usually I would use one or two melted chocolates, and simply melt and swirl them together on top of the set caramel. This time, however, I made it slightly different for a couple of reasons.
I used a mixture of melted milk chocolate (for the classic look element) and then I also added quite a considerable amount of melted Biscoff. The pro of doing a topping like this, it’s much easier to cut. Due to the additional ingredients that are in the Biscoff, it softens the top ever so slightly that means a knife cuts through the top more easily.
You can use any chocolate that you want (dark or white instead of milk for example) but that is entirely up to you – I like the mix of the milk chocolate the most, personally. I melt the chocolate until smooth, and then I also briefly melt the Biscoff spread so that the mixture is nice and runny, and then I pour it together and mix. Pour this over the set caramel, and then I sprinkle on some crushed Biscoff biscuits.
Top tips
- You MUST NOT USE tinned caramel for the filling. It’s not the same, and it doesn’t work – it will basically be a mess in the tin and also the taste isn’t as nice as the homemade caramel.
- I used this 9″ square baking tin in my recipe. If you want to make half of the recipe, use a 7″ square tin. The equivalent in a round tin for the original recipe, is a 10″ circle if you wanted to use a circular tin instead.
- This recipe will last for 7+ days at room temperature, but also it will freeze for 3+ months.
- 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.
- Biscoff spread is found in most supermarkets – you can use smooth or crunchy
- If you don’t want to use the spread, you can use 300g of chocolate on the top, and plenty more biscuits
- You can use fewer biscuits if you don’t want it as thick. Use 400g, with 135g of butter.
Biscoff Millionaires 'Shortbread'
Ingredients
Biscoff Base
- 500 g Biscoff biscuits
- 185 g unsalted butter (see blog post)
Homemade Caramel
- 200 g unsalted butter
- 3 tbsp caster sugar
- 4 tbsp golden syrup
- 397 g condensed milk
Biscoff Topping
- 250 g milk chocolate
- 200 g Biscoff spread
- Biscoff crumbs
Instructions
Biscuit base
- Blitz the biscuits in a food processor to a small crumb, and add the melted butter – either pulse in the food processor a few times until the mixture is combined, or mix it in a bowl.
- Tip the biscuits into a lined 9x9" square tin and press down firmly.
Caramel
- In a large saucepan pour the condensed milk, butter, sugar, and golden syrup 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 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 biscuit base and leave to set for one-two hours on the side. If it's hot, set in the fridge!
Chocolate
- Melt your milk chocolate down carefully in the microwave, or in a bain-marie.
- Also, in a separate bowl, melt the Biscoff spread for about 30-40 seconds so that it's softer and not as hard.
- Mix the two together, and spread on top of the caramel. Sprinkle over some Biscoff crumbs and then set on the side or in the fridge.
- Once set, cut up your pieces and enjoy!
Notes
- This will keep in an airtight container for at least 1 week – if they last that long
- 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.
- Biscoff spread is found in most supermarkets - you can use smooth or crunchy!
- If you don't want to use the spread, you can use 300g of chocolate on the top, and plenty more biscuits
- Using a tinned caramel in place of making your own, will NOT work. Tinned caramels do not set, so it'll be messy.
- You can use fewer biscuits if you don't want it as thick. Use 400g, with 135g of butter.
Hi Jane, I made this for the first time last week and it was also my first time making caramel and it came out perfectly! The recipe was so simple and easy to follow – they went down a treat at work. Making your Terrys Chocolate Orange brownies this weekend and im sure they will be just as delicious! I love your blog xx
Hi Jane. I’ve made this once before and it turned out perfectly. This time however my caramel seems to have split, the butters separated and I stupidly just went for it and poured it on to the biscuit. It looks more like cheese sauce! Do you think there’s any saving it? Did I heat the caramel too long? I stirred constantly. Gutted.
99% of the time when this happen, it was heated for too long/too hot! It might set okay, as it depends how split it was, but it won’t be the best!
Hi
This was delicious! However my chocolate seperate from the caramel when cutting it and some seperate from the biscuit. I let each layer cool completely before adding anything on top. What do you think went wrong?
The only thing I can think if that potentially it was either too cold, so it caused condensation? or the temperature between the layers was a little varied?
Made these for the first time a few days ago. Also my first time making caramel. I have previously burned milk fudge and honeycomb on all attempts so was expecting to have to try the caramel a few times, but it was perfect first time! This recipe really is fool proof. Everyone loves them! I’ve cut them into triangles so have 32 smaller servings which seem to be a good size.
Too cold when I’ve cut it or too cold when i added the chocolate to the caramel? I did leave the caramel in the fridge and put the hot chocolate after so it could be that?
Hi lovely!
Love this recipe it’s a firm fave. Just wondering. Can you freeze the bake??
Yes you can!
How is the best way to freeze please? Thinking of making this for Macmillan coffee morning on the 26th September and wanted to make ahead if possible
Thanks
Rachel
I would just add them to a freezer proof container!
Hi, made this and it tasted amazing. However, my biscuit base was very crumbly and didn’t hold together when cutting it up. Any advice? Many thanks!
You just need to really push it down firm before setting, and cut with a large sharp knife!
My base crumbled when cutting too even though I made sure I pressed down firmly before setting. Its a shame because it looked amazing
The crumbs need to be really fine before mixing in – a classic problem is that they’re not as fine as they need to be. As you can see from my photos the base is lovely and solid! If you struggle, you can add more butter.
If I can’t get a hold of Biscoff Spread, is there a substitute I can use?
You can just leave it out and just use milk chocolate… if you use anything else it won’t be biscoff related anymore!
I managed to buy the biscuits at b&ms if there is one near you 🙂
Hi Jane ,
This recipe looks amazing and I was trying to make it. But, unfortunately my caramel is very clumpy!! I saw your video and the caramel came out beautifully. So I’m in the states and we don’t have golden syrup and so I substituted corn syrup, do you think that was my issue? I also tried honey to see if it would be any different and I got the same result.
I would probably say so – I have never used corn syrup or honey in place, but as they are different it could lead to it not working! Have a look at the caramel on my Millionaires Flapjacks for an alternative!
Fabulous recipe. I’ve made it numerous times and always turns out perfectly. I do reduce the amount of biscuits in the base so it’s less crumbly when I cut it.
Amazing! They taste soo delicious. Great instructing regarding the caramel, mine turned out perfectly!
Haven’t tried your recipe (yet!) but tried Lotus biscuits in lieu of Digestives myself last year and it’s ten times nicer! Look forward to trying yours out.
Hi Jane. I just made these and they’re incredible! So simple to make and delicious to eat.
Hey, this recipe looks great! However, I only have a 7×10 tin, do you know how I would adjust this to fit my tin?
Thank you!
Hiya! Technically you need 0.9x the recipe, but its so small a difference that it should be fine as it is, it might just be a little deeper is all! X
Looks amazing. Big fan of Millionaires and Biscoff. Thanks!
Hi Jane! I just tried making your Millionaire’s Biscoff Traybake – and I’m not sure yet how it’s going to be! I had a few bumps in the road, but I think it may be okay. When I was making the caramel sauce, I think it might have heated too long, as there was liquid (a lot) that just wouldn’t mix in with the rest of the ingredients. That’s okay though – there was still fudgy caramel as the layer on top of the biscuit bottom. Also, by mistake I left the milk chocolate chips in the microwave too long – so they burned! I had semi sweet in the house – which probably would not be the first choice but I used it. It’s in the refrigerator now so we shall see! Looks delicious though!!
So… I had to buy two desperate sticks of butter from the shop due to the stock they had… only after making the caramel did I realise that the one stick was salted, and I used a majority of the stick for my caramel. It’s setting now, so hopefully it doesn’t turn out too badly! I mean, salted caramel is a thing, right?
I’m sure it’ll be fine!! x
