Biscoff Rice Krispie Treats!

Easy No-Bake Five-Ingredient Biscoff Rice Krispie Treats with a Biscoff Marshmallow Rice Krispie Base and a White Chocolate Biscoff Topping! 

Oh hey there Rice Krispies, it’s been a while… ages in fact! The last time I knowingly used Rice Krispies in anything was over three years ago – so it’s definitely time to sort that out! 

I love a good Rice Krispie treat.. they’re light, easy to make (even if a little sticky) but so quick! My version of a Toffee Crisp Cheesecake has always been so popular – the base is amazing – but so have my Millionaires Crispy Squares

Anyway… after doing a few recipe request posts on my social media channels recently, I had so many comments about want easy Rice Krispie related treats – so I thought I would start with the best… BISCOFF. Why not combine two of the best things? An easy no-bake treat and biscoff?! 

So, Rice Krispie treats are very easy. There are so many recipes out there, but I just couldn’t resist! You need a little butter (I use unsalted, but you can use slightly salted if you want to counteract the sweetness slightly), marshmallows and of course… Rice Krispies. Or Rice Pops as some people may also call them. 

I use mini white marshmallows because I find them the easiest to use. The mini part of them makes them melt a lot quicker, and the white colour means you don’t end up with a funny looking traybake. Although, if the colour doesn’t matter to you, you can use the mixed colour bags! 

You can use branded Rice Krispies or own brand – or even swap to cocoa pops (but generally I’d stick to the Rice Krispies). They create a lovely light texture, but also make it substantial enough! The only thing about making this though?! It’s so damn sticky!! 

I find it easiest to use a large pan – add the butter and mini marshmallows and melt on a low heat until the mixture is smooth. This is when you add in your Biscoff! You can use either the smooth or crunchy, but that’s up to you. Don’t add the Biscoff in at the beginning, as that can make the mixture split.

I weigh my Rice Krispies into a separate bowl, and add them to to the butter/marshmallow/biscoff pan, off the heat – the leftover heat of the pan makes it easier to mix everything together, whereas I find pouring the mixture into a bowl just makes more sticky mess! 

Press the mixture into the bottom of a lined tin – because it’s a no-bake traybake you can use a different sized tin, but for the same depth you want to use a 9×9″ square. For a top tip, you can slightly butter your hands to make it easier to press and smooth down the mixture. It saves a lot of panic, trust me! 

I then decorated with melted Biscoff and white chocolate – this can be milk chocolate, dark chocolate, no chocolate… whatever! It’s just what I had in the cupboard! You can also add in some biscuits to the mixture if you wanted, or even just decorate the top with them! It’s entirely up to you! 

This is definitely a recipe that is open for change, I just did this using what ingredients I had… If you want to try something else then let me know in the comments! I’m going to see what else I can make with rice krispies now…!

  • 50 g Unsalted Butter
  • 225 g Mini Marshmallows (I used white)
  • 175 g Biscoff Spread
  • 175 g Rice Krispies


  • 200 g Biscoff Spread
  • 200 g White Chocolate


  • Line a 9x9" square tin with parchment paper, and leave to the side.
  • Add the butter and mini marshmallows to a large pan, and heat on a low-medium heat, stiring, untill smooth and melted!
  • Once melted, take the pan off the heat and add in the biscoff. Stir briefly until smooth!
  • Pour the rice krispies into the pan, and stir to combine!
  • Press the mixture into the bottom of the lined tin (top tip, buttering your hands slightly can prevent any sticking and makes it easy to press down!)
  • Melt the white chocolate in a bowl until smooth - I do this in short bursts in the microwave stiring well each time.
  • In a separate bowl, melt the biscoff spread - This takes about 20 seconds in the microwave.
  • Pour the two over the rice krispie base and swirl together with a cake skewer.
  • Set in the fridge for two or more hours, and then slice and enjoy!


  • You can use slightly salted butter it you want the mixture slightly less sweet!
  • You can use smooth or crunchy biscoff spread. 
  • You can use cocoa pops in place of rice krispies if you want! 
  • The chocolate topping can be done with other chocolates if you fancy! 
  • Store at room temperature for up to five days!

    Hi! I had a similar issue to some mentioned above. Essentially the butter biscoff marshmallow mix turned into toffee ish texture, and so it was too thick to mix well with the Rice Krispies, and after they cooled, they were solid as a rock. I tried a second time with lower heat, and tried adding the biscoff to the butter and let that melt before the marshmallows, but still same issue. Added a bit of milk to reverse that effect and it worked for texture of the mix but then the taste isn’t the same anymore. Any tips please?

      Hii! It definitely sounds like it has got too hot as I have genuinely not had a problem doing it. It may be worth using some more marshmallows in the mix and see if that helps!x

    These were a disaster, It was impossible to mix the rice krispies into the gluey mixture. Is the quantity of butter correct, I have been making this kind of thing for years and would usually use 250g of butter.

    • Jane's Patisserie

      How strange, I’ve made these so many times with no problems! I would never ever use that much butter myself because of the biscoff! You can always use less Rice Krispies x

    Was planning on making these this evening but just realised I only have 200g of marshmallows! Do you think recipe will still work ok if I use same quantities of the other ingredients?

    • Jane's Patisserie
      February 12, 2021 at 8:16 am

      You might struggle as you need the quantity to make it mix – so I would reduce the other ingredients as well! x

      My bag was only 180g, so I worked out what proportion that was (180 divided by 225 = 0.8) then multiplied everything by 0.8.

      But I did the full topping. Worked a treat. ;o)

    Am I wise trying to make double the batch and split between 2 tins or will that volume be too difficult to mix and start setting before I get it smoothed out in the 2nd tin?

    • Jane's Patisserie
      February 10, 2021 at 7:35 pm

      I would imagine it would be harder to mix, unless you have a mahoosive bowl and arm power!

    Hi Jane.
    I’ve done the Nutella version of these before and they were amazing. I had a few problems melting the marshmallows. Actually it was a nightmare haha. Just wondering if you have any tips on melting the marshmallow, like what material bowl and spatula to use, is job or microwave best? Thanks a lot.

    Well…it’s in the fridge now…but I must have done something wrong – I wonder if you could offer some advice please? After adding the Biscoff, the marshmallow/butter mix become very thick almost immediately, making it very difficult to mix evenly with the rice crispies. Any advice you could offer would he appreciated.
    Many thanks,

      It sounds like it’s over heated – and potentially then split to make a paste almost x

    Hi another recipe and I have used many of your recipes! However of all the things I have baked, this did not turn out well for me lol 😆 I mean how can I get it wrong as it’s all just melting things?? My crispy part turned out awfully hard and crunchy as opposed to chewy. What did I do wrong? I put all the exact measurements in.

    • Jane's Patisserie
      January 15, 2021 at 8:25 pm

      Had you let it set in the fridge and eaten it straight away? It may have simply been to cold! But you can always add less Rice Krispies if you wanted! x

    Hi jane I love looking at all your recipes. On this one can I use dairy milk chocolate instead of using white chocolate as I’m not keen on white chocolate .

    • Jane's Patisserie
      September 18, 2020 at 10:14 am

      Thank you! Yes, as long as you can melt the chocolate, you can use whatever you want as it’s just the topping! x

  • Steph

    I don’t eat chocolate, but love the look of these! Do you know how I could maybe use a yoghurt like topping, like the covering for yoghurt raisins that will set hard?!
    Thank you so much! X

    • Jane's Patisserie
      September 12, 2020 at 10:49 am

      I haven’t done a yoghurt type topping on a bake before I’m afraid – but I do make yoghurt bars often and that’s just frozen natural yoghurt, so maybe try that?! It might set a bit softer though!

  • Kate

    Hi, how do you get a clean cut through the topping without cracking the chocolate?

    Hi Jane,

    Cannot wait to make these. My 10,067th bake from you as I love them SO much!! Haha!

    Just wondering, I have large pink & white marshmallows to use up, would the pink make the colour funny? Is it best to stick to white?

    Many thanks

    • Jane's Patisserie
      September 2, 2020 at 3:10 pm

      Because of the colour of the biscoff it may just be slightly different, but it would still work okay! x

    I’ve made these twice now……Gorgeous! However, I tried using vegetarian marshmallows on one attempt which didn’t work quite as well, because they just aren’t sticky enough. Any suggestions on how I could make them more sticky? I’m a veggie, and it’s really testing my resolve to just make these for other people! X

    • Jane's Patisserie
      August 10, 2020 at 4:46 pm

      I’m really not sure! It may be worth adding in some syrup? x

      My mixture once biscoff added was very chewy texture, I struggled to mix rice krispies in, but managed. Other than that a real treat. X

    Hey Jane this looks amazing!

    I was wondering whether you can replace the marshmallow in this recipe with anything? And is it possible to use cornflakes instead?

    • Jane's Patisserie
      August 6, 2020 at 10:37 am

      Thank you! These really are based around marshmallows, so you’d have to look for a different sort of recipe – I have seen ones with peanut butter, or syrup for example, or you could use melted chocolate like with my biscoff rocky road! x

  • Sam
    August 6, 2020 at 7:03 am

    Hi jane can you use baking block with this recipe? I have tonnes of it but can’t actually find a recipe that uses it!

    • Jane's Patisserie
      August 6, 2020 at 10:09 am

      Hey! Yes as long as it’s a butter type substance, it should work absolutely fine!

  • Bethany
    August 5, 2020 at 12:00 pm

    Wow, I cannot wait to try these!!! Biscoff and white chocolate are two of my absolute faves. Is there anything I can use in replacement of butter please? I really dislike butter (its fine in cakes when I know I wont taste it) and am worried I’d get the taste of it amongst the other flavours as it isn’t being baked… Sorry, probably a silly question!
    Thank you in advance, love your recipes!

    • Jane's Patisserie
      August 5, 2020 at 2:46 pm

      Hey! The amount of butter in this really is small, and you won’t be able to taste it – it just tastes of marshmallows and biscoff!! – it’s the best thing to use to get the end results! x

    • Claire
      August 13, 2020 at 6:17 pm

      Would fluff work as well as marshmallows?
