I love making Biscoff recipes and couldn’t wait to make these rice krispie Biscoff squares! I haven’t made rice krispie squares in forever and as I went on a little binge buy of the Aldi Biscoff spread dupe I needed some recipes to make and this one was on the top of my list. Baking with Biscoff is so much fun and so tasty, my partner took these to work and they went down a total treat, even if they’re not overly healthy and got eaten up before lunch.

If you’re looking for an easy Biscoff recipe, this one is for you. I did double up the recipe as I made some for my partner to take to work, some to give to our friends and some to share with my family. If you want to double up the recipe, you can, and it works just as well. You might just need a bigger pan to melt your marshmallows in and be quicker when you make it so the marshmallows don’t set too fast as you need to mix them in with the rice krispies very fast.

Rice Krispie Biscoff Squares Recipe UK

I’ve seen a few of these recipes online and I have to say it gets really annoying when the recipe card isn’t in grams. I am terrible with conversions no matter what conversion chart I look at and I’ve had many recipes that have failed before I’ve not got the conversions right and there’s nothing worse than a recipe not working because you’ve used the wrong measurements. This is why the recipe card for this Biscoff squares recipe is all in UK measurements, sorry to everyone else in the world that doesn’t use grams!

A little tip with this recipe, make sure you use a lined baking tray or a silicone baking tray. I used both as I had to double up and if you line the baking tray it means you won’t have to pry a sticky mess off the edges of the tray. The silicone baking tray was sent from heaven, they’re so easy to use and a total investment for your baking. I’ve been using one for around 4 years now and it’s still going strong.

Easy Biscoff Cake Recipe

This Biscoff cake recipe is so much fun, totally tasty and a lot easier to make than these rice krispie biscoff squares, but the squares are totally worth the effort! This cake is super easy to make, you have to make sure you crumble Biscoff cookies on the top because not only does it give it a better texture but it also looks amazing. The cake will need to be eaten up within 2-3 days though as the biscoff biscuits can go a little soft and that’s no fun at all!

If you have any recommendations of Biscoff recipes I should be making then you must let me know in the comments! I want to make a yummy Biscoff cheesecake at some point as well although cheesecakes can take a lot of time so I’ll have to plan that out. Thankfully, these rice krispie Biscoff squares recipe UK doesn’t take that long as well!

Rice Krispie Biscoff Squares Recipe

I’d love to know if you liked this recipe as much as I did and everyone else that tried them did as well. They’re very popular and I’m yet to meet someone who doesn’t like Biscoff! Biscoff is really nice but you have to make sure you don’t use too much of it or it can be a little overpowering that’s for sure. If you’ve made this let me know, if you upload a picture think about tagging me in it on Instagram so I can see you’ve made it because I feel well chuffed when people do that!

The recipe below is enough for a nice batch but if you’re looking to make a bigger batch you can double up the recipe. If you double up the recipe I find that you can make huge squares which look so much better. I also find that if the squares are bigger most people will only have one so if you’ve made 40 for 20 people, they might last a while. They’re perfect for children’s parties though and children love this recipe, who doesn’t love baking with children? I repeat baking WITH children and not baking children.

  • Line a 9×9″ square tin with parchment paper and set it aside.
  • In a large pan, combine the butter and mini marshmallows. Heat them over low to medium heat, stirring until they become smooth and completely melted.
