I love a good loaf cake because as much as I love buttercream, cake sponge is my favourite thing and it really gets centre stage in a loaf cake. There’s been so much love for my Chocolate Orange Loaf Cake recipe, so I really wanted to make a Biscoff version as it’s such a popular flavour. I’ve mixed Biscoff spread into the batter for this Biscoff Loaf Cake, and I’ve used brown sugar for a caramelised colour and flavour. I like my loaf cakes to be quite big for maximum sponge, so this one is baked on a low temperature for over an hour to create a lovely flavoursome and moist cake. The buttercream also has Biscoff spread in it, and I’ve decorated it with Lotus Biscoff biscuits of course!
How to make a Biscoff Loaf Cake…
To make the sponge I mixed the butter, Biscoff spread and sugar together, then whisked in eggs.

Then I added self raising flour and whisked in.
I poured the mixture into my lined loaf tin and baked it for 1 hour and 15 minutes.

I made a Biscoff buttercream and decorated the top of the loaf cake with it.

For more Biscoff deliciousness I decorated the top of the Biscoff Loaf Cake with as many Lotus biscuits as I could fit!
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 long does the Biscoff Loaf Cake last for and can you freeze it?
The cake will keep in an airtight container for 3 days in a cool place. You can freeze the sponge either alone, or decorated (but do not freeze the biscuits). Once the sponge is fully cool, wrap it well with cling film or put in an airtight container with some baking paper between the slices. You can freeze the buttercream on it’s own in a tub, or you can decorate the cake and freeze it fully assembled.
To do this and avoid damage to the decoration, freeze it either in an airtight container. Or let it freeze solid on a cake board or plate, then wrap in cling film. Remove the cling film when you take it out to defrost it, if you don’t it could damage the decoration as it defrosts and softens.

This cake looks sooo delicious moist! I love Speculoos so I cant wait to try it 🙂
Am I reading the recipe correctly or incorrectly? I cooked the cake at 350 for 1 hour 15 mins and it came out very much burned. That’s never happened on a recipe before, usually the cook time is near accurate, give or take 5 minutes but it looked like I should have taken it out 20 mins earlier 😅 I want to try again, altogether the ingredients promise that this should be really good.
Hi Vasili, I’m sorry to hear that happened. The baking times are based on how long it takes in my oven, however all ovens are different which is why I also recommend taking it out when a skewer inserted in the centre comes out clean. You know your oven best so if you think it is done earlier, and it passes the skewer test, then it is ready.
Kat, you’ve done it again… this looks amazing! I’ve a packet of Biscoff biscuits in the cupboard that I was going to use for a cheesecake, but I might have to made this instead 🙂
Biscoff lovers rejoice! Wow, Kat what a fabulous loaf! It looks so moist and that buttercream full of biscoff spread as well – heaven! Thank you for sharing your recipe with #BakingCrumbs 🙂
You’re the queen of biscoff! This looks so delicious!
Mmm. I love the crumb. Looks delicious. I can just imagine how the brown sugar and biscoff go together so well.
Thanks for sharing at #CookBlogShare!
I love your Biscoff recipes!!! I can’t get enough of the stuff. Plus I love a loaf cake too. So simple to bake. This is a genius recipe and a real showstopper. I am definitely going to bake this. I say that about all your recipes! Thank you so much for sharing with #BakingCrumbs
What a great recipe so you can have your cake – and cookies too!
did this as a school recipe and got good gcse mark
would recomend it
Amazing recipe! Easy enough to bake, and absolutely delicious. Thank you, can’t wait to try more x
Cant wait to try this but want to ask is the sugar in the cake golden caster or soft brown?
Hi Margaret, it’s light brown sugar as listed in the recipe ingredients, I think sometimes it’s also called soft brown sugar 🙂
The perfect Lotus cake! The buttercream turned out super soft and fluffy with the perfect amount of Lotus taste! The cake is not overly sweet so the buttercream provides just the right amount of sweetness to the cake! Was delicious! Want to try the Lotus Cupcakes next time 🙂
Thank you Saimah!!
I made this today and it came out perfect! It was moist, not too sweet but perfectly lotus flavoured and a bit hit with the family – thank you :))
Thanks so much Ella!
Could I possibly increase the biscoff spread in the batter to 130gms instead if 100gms for a bit more flavor? Would it be alright? Please advise 🙂
Yes I think that would be fine! Let me know how it goes 🙂
I baked this cake for our charity bake at work and it was a hit. The recipe is spot on. Thank yo Kat – @revsfouryou
Thank you so much Eva!
Hey I’m wanting to use this recipe to make it in a round 9inch would it be the same Ingredients and time in the oven? Thanks
Hi Humairah, you could make this in a 9 inch round tin, but it would have to have deep sides – I’d say 2 inch tall minimum. It’s hard to say on the baking time as I’ve never baked it in that size tin, I’d estimate 30-40 minutes, but please do check it’s cooked through before taking out of the oven. Let me know how it goes!
Amazing recipe, thank you sharing. Btw I used 200grams of powdered sugar instead, and it was delicious and perfect consistency!
🤍
May I ask what the weight of the eggs you use are? We usually buy mixed size farm eggs as its more value for money so when i bake I weigh my eggs, if that makes sense. I love your recipes. Thank you for sharing
Hi Faz, I used UK standard large size eggs, which according to google weigh between 63g and 73g. I hope that helps!
Easy to follow recipe and tastes SO GOOD! Cake was moist, Biscoff flavour was just enough. The whole family loved it
An easy and delicious cake. Mine, however, took just 1 hour to bake so I would advise anyone who wants to bake it to check with a skewer after an hour (all ovens are different)!!
Amazing recipe, can’t wait to try!
I’m new to baking so this might be a stupid question but do you use salted or unsalted butter?
Hi Shannon, there are no stupid questions 🙂 I used unsalted butter for all of my baking, I hope you enjoy the cake!
Is the conversion tab on the recipe somewhere ? I know it’s on some of your others, and maybe I’m overlooking it? Thanks!
Hi, what conversion are you looking for? Is it to cups?
After 20 minutes in the oven I could smell it was burning, but looked raw. After 40 minutes, the burning smell was worse. After 45 minutes, I threw foil on top to keep it from getting darker. It came out at 1 hour with a burned crust all over it. Not sure why, since I followed your directions when preparing the pan and setting the oven. I made no ingredient mods. I carved the burned parts off and salvaged the middle, which tasted great! Too bad I had to trash 1/2 the loaf.
Hi Andrea, what temperature did you bake it on? It sounds like your oven was too hot, which is what causes the burnt on the outside/raw inside issue. Some ovens can be as much as 40C different from what the dial says, an oven thermometer will tell you the true temp inside your oven and they’re cheap to purchase.
This looks amazing I’m going to try it today! I’m planning on making them in mini loaf cases as gifts – should I alter the cooking time 🙈?
Hi Jess, I would suggest baking for a similar time as cupcakes (I’ve never made mini loaves but I believe they are a similar size). So 20-25 minutes. Always check they are done by inserting a skewer in the centre, if it comes out clean then they’re baked.
My recipe has spilt out of the tin all over the oven … just checking it is a 2lb loaf tin?? Thank you
Hi Melissa, yes it’s a 2lb loaf tin for this recipe! Hope your oven isn’t too much of a pain to clean!!
Amazing recipe it was eaten within a few hours 😂 xxx
Excellent recipe and a delicious cake. Love the Biscoff buttercream and the Biscoff in the sponge tastes great too. My loaf tin was slightly too small so I used 75% of all the ingredients and baked it for an hour (I covered it halfway as the top was starting to catch) and it was the perfect size.
