Biscoff Cake!

A delicious and moist 3-layer Biscoff cake with Lotus biscuits! Perfect spiced and sweet cake for all biscoff lovers out there!
I now have a good few Biscoff recipes on my blog and they are always super popular because a lot of you seem to have the same adoration for Biscoff as I do! I recently updated my biscoff cupcakes recipe to have some new pictures and they were such a massive hit I thought I would post my cake version of the recipe!
My recipes for my no-bake biscoff cheesecake and my biscoff fudge so I know that you guys will LOVE this. If you aren’t sure what biscoff is then I have no idea how else to explain it other than it is just DELIGHTFUL! Please check it out if you haven’t already – and you will understand my obsession.
I used a simple cake recipe using equal ratios of sugar/butter/flour/eggs as the base of my cake because it always works in my opinion, and it creates such a light and moist cake that there is no point messing with it.
Using the ratios works with most sponges – and the best way is to use the weight of eggs in their shells, and match the rest of the ingredients to that. I use 7 medium eggs roughly in this cake – but say they equalled 410g, I would use 410g butter, sugar and flour as well! This isn’t essential, it’s just the easiest way to get the best sponge.
Using the twist of light brown soft sugar in the sponges of the cake as I have in a few of my recipes now it really does work. I personally find that it makes the sponge actually that much moister and it’s utterly delicious compared to using normal caster sugar. This is of course optional though – you can use caster sugar or even dark brown soft sugar! Or a combination!
The cake has a lovely natural caramel taste to go with the caramelised theme of the Biscoff so it’s utterly dreamy. The biscoff flavoured buttercream is deliciously light and moussey even though it has the addition of the biscoff itself so this cake is perfection in my eyes.
When making the buttercream it is so important to use BLOCK unsalted butter and not a spread or margarine of any sort. I always believe and will say this forever and a day that block butter is so important. I know it’s solid as anything, and you need to wait for it to be room temperature before you can use it – but it then sets so firmly after.
If you use a baking spread or similar, you risk making the frosting far too soft. By the time you add the biscoff spread, you don’t want to end up with biscoff buttercream soup – and this is a definite risk. Top tip as well if your frosting splits – add a tbsp or two of boiling water or full-fat milk – it will bring it right back!
As my previous cake recipe to this, my caramac cake, had a drip-style to it I thought I would go back to my classic sort of baking styles and just layer them up with buttercream in the middle. I used the biscuits in the middle of each of the sponges and on top because it gives the little bit of a crunch that I always crave in a cake and without using the same sprinkles again, but this is optional.
My mum took this bake to her work as my family is a bit caked out at the moment so I thought it would be an idea to give it away to keep her colleagues happy, and I’m not joking when I say that it disappeared SO quickly I was even a tad shocked.
Like, I know usually there are some people that say no to cake because they are on a diet, but JEEEEEZ this one just went! So much biscoff loving. But seriously, this cake would be ideal for those who love cake but nothing too sweet, and definitely one for this caramelised delicious Lotus/Biscoff/Speculoos lovers out there!
Biscoff Cake!
Ingredients
Cake
- 400 g unsalted butter (room temp)
- 400 g light brown soft sugar
- 7 medium eggs
- 400 g self-raising flour
- 2 tsp baking powder (optional)
- 1 tsp vanilla extract
Buttercream
- 250 g unsalted butter (room temp)
- 500 g icing sugar
- 300 g biscoff spread
- 2-3 tbsps boiling water (if required)
Decoration
- 4 crushed biscoff biscuits
- 12 biscoff biscuits
- 50 g biscoff spread (melted)
- sprinkles
Instructions
For The Cake
- Preheat the oven to 180ºc/160ºfan and line three 20cm/8inch round cake tins with baking parchment – leave to the side.
- In a stand mixer, beat together the unsalted butter and light brown soft sugar for a few minutes until light and fluffy.
- Add in the self-raising flour, eggs, baking powder (if using) and vanilla and beat again briefly until combined.
- Divide the mixture between the three tins and smooth it over – bake for 25-30minutes until the cakes are golden and when the cake springs back (skewer should also come out clean)!
- Once baked, leave the cakes to cool in their tins for 10 minutes or so, and then remove and leave to cool fully on a wire rack.
For The Decoration
- Beat the room temperature unsalted butter with an electric mixer for a couple of minutes to loosen it
- Gradually add the icing sugar on a slow speed until it is combined then speed the mixer up and mix for 3-4 minutes until thoroughly combined and smooth.
- Add in the biscoff spread to the buttercream and continue mixing, and gradually add the boiling water until you reach the desired texture if it is needed! Keep on beating for 5 minutes until whipped and silky smooth!
- Using your favourite piping tip, I used a large round tip, pipe the buttercream onto the bottom layer of the cake. Add the second layer, and pipe buttercream on again!
- Add on the third layer of the cake and pipe on the rest of the buttercream.
- Drizzle over some melted biscoff spread, and add on some biscuits, crushed biscuits and some sprinkles. Alternatively you can just slather the buttercream on instead! Enjoy!
Notes
- I love this style of cake as you can tell from the few I have made, and I happen to have 3 8″ tins, if you don’t have 3 tins you can make a smaller version of the cake with two 8" tins (Can take slightly longer to bake)
- 300g Butter
- 300g Sugar
- 300g Flour
- 6 Medium Eggs
- 1.5tsps Baking Powder/1tsp Vanilla
- 2/3 of the decoration recipes!
- You can buy the Biscoff/Lotus spread in nearly all supermarkets in the UK now, its usually found next to Nutella!
- I wouldn't add the water to the buttercream unless it is essential. Often on a sunny or warm day, it won't be needed!
- This cake will last in an airtight container for 3 days, at room temperature.
- I used a large round tip, to decorate this cake!
ENJOY!

Where is your icing nozzle from? x
I couldn’t tell you exactly as I’ve had it for ages – but a close on is this one! https://www.icedjemsshop.com/shop/2d-piping-tip/?ref=13 x
Hi Jane, I am currently baking your cake, but I have a major problem. I have used regular flour instead of self-raising flour. The cakes are in the oven and I am wondering if I messed up or if it will be okay..
They might just be quite flat in comparison to risen and fluffy, but only time will tell now I’m afraid!
It was terrible.. I had to re-make them, but it was worth it! It was soooooo good!
Oh dear ? Well I’m glad it worked out in the end!!
This cake is just simply delish, yummy and gorgeous. I found this cake incredibly easy to make and it turned out nearly exactly like your picture. Lots of complements from my family. Thanks x
Oh yay! I’m so glad you and your family liked it!! Thank you! x
Hi Jane,
I love the idea of this cake and it looks incredible so definitely going to try making it for my boyfriends birthday only I know he really thinks the drip down icing effect is really cool like the caramac one you made, how could you convert that to his recipe do you think?
Any advice would be really great,
Thank you 🙂
I would do the sponge the same, but use 1.5 times the amount of buttercream if that makes sense? And don’t put as much in the middle as I have, about 2 tbsps for the two filling layers, and use the rest to decorate the top and edges. You can melt down Biscoff Spread gently as well and use that as a drip, or use the drip method on my Caramac or Oreo cakes!
Hi Jane, this recipe looks amazing! I’m planning on turning this into cupcakes, I was wondering how much buttercream would be needed to ice 24 cupcakes? x
I have a biscoff cupcake recipe already on my blog which you can use 🙂
Hi, I’m planning to make this cake and wondering if I can use whipped cream instead of buttercream. And if so could I still add the biscoff spread into the whipped cream?
If you use whipped cream you’ll have to store the cake in the fridge as dairy shouldn’t be out of the fridge for more than 4 hours, and you can add biscoff to the cream, but it might not whip the same x
This looks a truly yummy cake, do you prefer to use the smooth or crunchy spread? Which works best in your opinion?
Either will work perfectly, I used smooth though as I could pipe it, if you use crunchy it might block a piping tip x
Hi Jane, I have just found your website through the wonders of pintrest. I am currently planning my wedding and wedding cake which I am planning on making myself. My addiction to biscoff is REAL! I found this recipe and obviously it needs to be part of the big day. I’m planning on each tier being different (planning, whether it works is another thing) Do you think this cake is firm enough to be stacked as a middle tier of a 3 tier cake (will be supported with dowels too). Look forward to hearing back from you xxx
Hiya! Oh that sounds intense, I don’t know if I could make my own cake! I’m sure it would work, but its VERY soft, so maybe add in 100g of plain flour to the mix, and mix the mixture for about 5 minutes with a beater attachment so its silky smooth, and it’ll end up like a madeira cake almost… I realise madeira cakes are a little drier, but you could use a simple sugar syrup to keep the cake moist, and the slather on the Biscoff Buttercream! x
Has anyone tried making this as a 6″ and three layers? How much would you need to adjust the recipe?
This looks incredible! I’m just new to baking and loving it, I’m going to make this next weekend for my boyfriend’s birthday (we are both huge Biscoff fans!), what piping bags/nozzles do you recommend? I’ve tried some in the past which seem to fall apart whilst using :(.
I’ll definitely be keeping up to date with your blog it’s fab! Thanks xxx
I use large nozzles which you can buy online, like the Wilton 1M or a large star, and I use Savoy disposable bags and they work perfectly! xx
Hi Jane, I made this cake and it all was good apart from the icing. While I was piping it, the butter was literally seeping out of the bag and by the time I had done half of one row, I was left with hard ‘icing’ that had no butter or moisture in it. What gives? The room was cool, the cakes were cool, I had rinsed my hands in ice water before starting. This was so disappointing as it ruined the aesthetic of quite an expensive cake. 🙁
Hiya – chances are you split the buttercream. It’s not the recipe that’s incorrect, it’s something that’s been done whilst making it, as this recipe is based on a basic buttercream. You didn’t need to cool your hands in ice water or anything before piping it as well.. sorry you had problems, but as I say maybe there was something wrong with the ingredients you use, or you’d split the buttercream.
This cake looks amazing !! However I am allergic to eggs :/ do you think that using the egg replacer would work?
Hiya – I’ve never used an egg replacer as I’ve never done egg free baking so I wouldn’t know I’m afraid 🙂
Hey there! I’m so excited to make this recipe for an international potluck I’m a part of (I’m in America, but I’m obsessed with Biscoff!). I do have one question though. Would it be possible to put some cookie butter or even cookies into the batter itself? If so, how much do you think would be a good amount?
Thanks so much!
Hiya! I wouldn’t personally as I don’t think the taste transfers through after baking so would basically be pointless 🙂 x
Hi,
This cake looks amazing!! I wondered how long the biscuits stay crisp in the cake for? I’m really excited about baking this for my friends birthday but the cake would be left out on a table for a few hours, probably in a warm-ish room. Will the biscuits stay crunchy?
Thanks 🙂
I can’t quite remember if I am honest, but inevitably they will go soft eventually.. maybe put the biscuits on top as late as you can?! They don’t ever go super super soft, but will eventually be not as crisp 🙂 x
