I have a lot of Biscoff recipes on my website, and I'm so excited to add these Biscoff Blondies to the collection! They are fudgey white chocolate and brown sugar blondies, swirled with Biscoff spread and topped with Lotus Biscoff biscuits. White chocolate and Biscoff go so well together, and these blondies really are super moreish and delicious! I really do love blondies, they are basically the white chocolate sisters of brownies, and if you've not tried them yet then you really need to!
Ingredient Tips & Equipment Information
- You can use either butter or a baking spread for the blondies.
- Avoid using cooking or baking chocolate for the blondies, and also I don't recommend using Milky Bar or any white chocolate with low milk solids.
- If you don't have light brown soft sugar, you can use regular caster sugar.
- For the best flavour, make sure to use a good quality vanilla extract and not an essence.
- Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales*. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50) .
- For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons* and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.

How to make Biscoff Blondies
In a pan on a low heat melt the butter and light brown soft sugar together. Then add the white chocolate and stir it in.
Whisk in eggs, vanilla extract and plain flour, then pour the batter into the tin.
Next, add blobs of Biscoff spread on top, and use a butter knife to swirl it into the batter.
Once the blondies had baked for 20 minutes, take them out and press the Lotus biscuits into the blondies. Then bake them for a further 10 minutes.

What is Biscoff?
Biscoff spread, made by the brand Lotus, is also known as cookie butter. It has a deep caramel flavour and a hint of cinnamon and other spices. Lotus are best known for their biscuits, which are commonly served with coffee. The biscuits are used to make the spread, and you can buy it in crunchy and smooth varieties. The spread is similar to Nutella or peanut butter in terms of texture, but it has a unique flavour. It’s also naturally vegan!
How do you know when the Biscoff Blondies are baked?
I bake them in my oven on 160C Fan for 30 minutes until they are golden brown all over like in the photos. Using a skewer inserted in the centre doesn’t give a clear indication that they are done because blondies are meant to be gooey and almost a little under cooked. Blondies are the white chocolate version of brownies and they are not like cake. They will also set more as they cool down, wait until they are cool to remove them from the tin.
What white chocolate should you use for blondies?
I have made this recipe using both supermarket own brand white chocolate and Callebaut callets. If you use a better quality chocolate, it will improve the flavour. But of course supermarket own brands are great for keeping costs down. I would advise avoiding cooking or baking chocolate, and also I don’t recommend using Milky Bar.
Can these blondies be made gluten free?
Making these blondies gluten free is easy! All you need to do is replace the plain flour with a gluten free plain flour blend. You may also like to add ¼ tsp xantham gum for better texture. Please do check the labels for everything you use to make this recipe if you are serving it to someone with an allergy or intolerance.
Tips for making the Biscoff Blondies:
- If you don't have light brown sugar, you can also use caster sugar, or golden caster sugar.
- You can use crunchy or smooth Biscoff spread.
- If you have a 8" or 9" square tin, check the notes section of the recipe at the end of the page for how to convert this recipe for a smaller tin.
- You can freeze these blondies if you wrap them up well.

- 3 Eggs large
- 225 g Plain flour
- 150 g Biscoff spread
- 12 Lotus biscuits
Instructions
- Pre-heat your oven to 160C Fan/180C/350F/Gas Mark 4 and grease and line a 12" x 9" traybake tin
- Melt the butter and light brown caster sugar in a pan on a low heat until the butter is melted
- Remove from the heat and add the white chocolate, leave it for a few minutes for the chocolate to melt, then stir together. Leave the mixture to cool for 5 minutes. Don't worry if it looks a little lumpy, it will go smooth again when you add the eggs
- Whisk the eggs and vanilla extract into the mixture
- Add the plain flour, whisk in until you can't see any flour
- Pour the batter into the lined traybake tin and add blobs of the Biscoff spread all over. Use a butter knife to swirl it around a little bit - don't over mix
- Bake for 20 minutes
- Take the blonies out of the oven, press the Lotus biscuits into them, then put them back in the oven for 10 minutes, or until they are golden brown all over. Using a skewer inserted in the centre doesn’t give a clear indication that they are done because blondies are meant to be gooey and almost a little under cooked. Blondies are the white chocolate version of brownies and they are not like cake. They will also set more as they cool down, wait until they are cool to remove them from the tin and slice into pieces
- Store in an airtight container in a cool place and eat within 3 days

Lena
Hi, if I wanted to use a 10x10 to , should I leave the recipe alone?
thebakingexplorer
Hi Lena, I've never tried it in this size tin. I think it would be ok but it would need a bit longer to bake. Let me know if you try it!
Radwa
Looks delicious! Thanks for sharing.
Chloe Edges

Natalie Hewitt
I made these with my brownie loving boys and the recipe was really easy to follow. They did most of the baking and the brownies turned out perfect. Lovely fudgey centre and just the right amount of biscoff flavour. We will definately be back to make more of your recipes x
Cm
Hey would these work with a 12” x 12” tin if I increase the ingredients slightly? (I’ve used an online converter to adjust the ingredients) And do you know how much longer I would have to bake them for? Thank you ☺️
thebakingexplorer
Hi, I've never made them in a tin that size myself so I'm not sure on the baking time, but yes if the ingredients are increased appropriately then I am sure it will work well!
Mia
hello was just wondering for this recipe if where it says 492 calories, is that per slice/serving or for the whole batch?
thebakingexplorer
Hi Mia, it's per serving, the calories are calculated using an online tool so if you want it to be super accurate I'd advise putting your exact ingredients into an app like MyFitnessPal as there will be slight variances between brands. I hope that helps!
Liz Clancy
Recipe worked brilliantly!
Tastes gorgeous xx
Katie Bor
I love biscoff anything and these defo didn't disappoint! They were so gooey and tasty - just like brownies should be! I will defo be adding them to my list of things to bake again (soon I hope!)
Daniella
Great recipe - easy to follow with delicious blondies at the end! Will be baking these again soon ⭐️⭐️⭐️⭐️⭐️
Emily
Would I be able to make the mix for these Blondies and then add kinder in to make them kinder instead of biscoff? Thanks x
thebakingexplorer
Hi Emily, do you mean kinder chocolate bars or do you mean a kinder spread like Nutella? You can swirl Nutella spread into the top the same as the Biscoff, if you want use kinder chocolate bars then chop them up and mix them into the batter. I hope that helps!
Emily
More of thinking melting kinder bars and swirling through in replacement of the biscoff spread? Do you think that would work?
Emily
Also what butter would you recommend? Stork? Unsalted block? X
Ellie
I haven't baked for about 10 years as my cakes always came out rubbish but you have inspired me again with your recipes, thank you! I'm going to try these blondies next week but can you just tell me how the ingredients change if I only have small eggs please?
Thanks so much
thebakingexplorer
Hi Ellie, I'm so pleased to hear I've inspired you! Please can you let me know how small the eggs you have are? Not sure where you're based but I'm in the UK and we only have large or medium eggs.
Ellie
Oh wow thanks so much for a quick response. Ooops sorry, the eggs are Tesco medium! They look small.....! I'm based in sunny Gorleston in the UK.
Ellie
So, just wondering if there's a difference if I use medium eggs instead of large?
Lucy
Really good. Baked these as a 'mini bake off!' They taste superior and were gone within an hour in my family of 5.
asa
The base of my blondie is wet but the top is cooked and the inner is gooey. Where am i going wrong?
thebakingexplorer
Hi, did you change any ingredients, bake it in a smaller tin or do anything differently? Using low quality white chocolate, cooking chocolate or Milky Bar can also cause this issue.
Katie
These turn out absolutely perfect every time, truly the best blondie recipe I’ve found!
thebakingexplorer
Ah thank you Katie! This is lovely feedback!
