Biscoff Bakes

When it comes to baking with Biscoff, we all know I am completely utterly obsessed and I have no shame about this. I adore it, I adore the caramelised biscuit flavour of HEAVEN and I have made so many biscoff bakes so far.

I have at least 25 Biscoff recipes published at this point, it’s a surprise I don’t have shares in the company, but hey ho. Honestly, my biscoff brownies are always a delicious bake, my biscoff cheesecake is the most popular recipe I have ever published, and even more recently my biscoff rolls are an addiction of mine.

Biscoff, also known as speculoos, comes in a biscuit and spread form and I just love to marry it into so many different things I can in the baking world. For this one, after countless requests, I am finally doing my version of a biscoff loaf cake.

Loaf Cakes

Loaf cakes for me have always been one of the most popular things I can post. Honestly, you all love a loaf cake and I had no idea that they would be so popular, but I am not complaining. There is something that is so easy about a loaf cake and I just adore it

I always use the same 2lb loaf tin when I make my loaf cakes as out of all of the bakeware, the most unreliable product is a loaf tin. I have genuinely bought 15 of them now, all classed as a 2lb/900g loaf tin, and they are incredibly inconsistent.

This is the loaf tin I use in all of my loaf tin bakes. Therefore, the general rule for loaf cakes is to only fill a loaf tin 2/3 full, so that it doesn’t over flow. If you ever have spare mix, you can make cupcakes (bake at 160ºc for 20 minutes) so you don’t waste any mixture.

The Cake

When it comes to the cake, it’s a simple sponge mix that I have decided to change up ever so slightly on this cake and add a little flavour. This is entirely optional, as my other biscoff cakes don’t have this, but I went for the idea of the classic speculoos spices.

  • Butter – because this is a cake sponge, you can use a baking spread, or unsalted butter, both work well
  • Sugar – I used light brown soft sugar to stick with the biscoff idea, a little bit of natural caramel
  • Eggs – I always use medium eggs in my bakes so I have used 4 medium. If using large, three is probably closer
  • Flour – self raising flour as always for cakes. If you don’t have it you can make your own by mixing 2 level tsps of baking powder in to 150g of plain flour and mixing well before using in a recipe (the standard ratio)
  • Spices – I used a small amount of cinnamon, ginger and nutmeg. These are optional, or you can use more or less of whatever you want.

The Frosting

The frosting is a simple biscoff buttercream, as I didn’t want to mess with this part. I wanted a thick and delicious frosting to pipe onto my cake, and this biscoff buttercream is exactly that.

Butter – for this, you want to use a block butter and not a margarine, or baking spread, otherwise it’ll be too soft.
Sugar – I use icing sugar (also known as confectioners sugar) in other places
Biscoff – the beauty that is. I use the smooth biscoff spread as then nothing will clog the piping tip, but if you are just slathering the frosting on then the crunchy one does also work.

Decoration

For the decoration, I decided I would go fairly standard when it comes to a loaf cake as I think there are only so many ways that you can decorate a loaf cake.

I used my favourite 2d closed star piping tip with my favourite large piping bags to pipe a ‘rope’ look onto my loaf cake, and then used my small piping bags to drizzle on some melted biscoff spread (which I had melted in the microwave).

Then, I used some whole biscoff biscuits to place onto the top and crushed over some biscuits as well. The biscuits will go soft once they’re out of the packet which is entirely normal, but if you hate it, I’d leave them off until the last minute.

    What’s the nutrition information on this per slice please? On a calorie deficit diet but want to be able to enjoy yummy things also!

    So easy to follow, absolutely scrumptious! I made two cakes at the same time…. Family favourite on the way…

    Thank you!
    Continue sharing your amazing creations!

    I made this cake and baked at recommended temperature and for recommended time. The cake was really dry baking at such low temperature for an extended time. The frosting was good. I may adjust the bake time and temperature and see how it turns out.

    • Jane's Patisserie on April 8, 2025 at 11:30 am

      All ovens can vary, so you likely just needed slightly less baking time for your oven or you need to bake at a lower temp x



  4. Victoria on January 29, 2025 at 3:28 pm

    Could I use this recipe for a tray bake instead of a loaf tin?

  5. Sarahmarie on November 3, 2024 at 3:03 pm

    Could this be done in a round tin

  6. Barbara on November 2, 2024 at 2:49 pm

    Hi Jane,
    Thank you for your recipes.
    I have made your Biscoff Brownies & Cupcakes a few times – both yummy!
    Wonder if it is possible to put Smooth Biscoff Spread into the loaf cake mixture, perhaps instead of the spices?
    Is it possible? If so when?
    Thank you, Barbara

    I love this recipe, so easy to mix together. I made a few adjustments to the cake, replaced the spices with all spice (which contains cinnamon, nutmeg, coriander seeds, caraway, ginger and cloves) and added raisins. It’s so scrumptious

  8. Liz on October 13, 2024 at 9:38 am

    Are you meant to melt the biscoff spread before adding to buttercream? Ours tasted delicious but had a rough texture.

    • Mags on April 17, 2025 at 3:37 pm

      Hi Jane, I use the same loaf tin every time but I find it always raises in the middle so not even height across. Do you just trim off the extra ?

      Thanks!



    • Jane's Patisserie on June 8, 2025 at 2:43 pm

      This can be due to your oven, but also loaf cakes do tend to naturally rise more in the middle and this isn’t a bad thing x



    • Penny on May 30, 2025 at 7:50 pm

      There are two types of biscoff spread Liz, smooth and crunchy. Is it possible you used the crunchy?



  9. Jade on September 16, 2024 at 11:15 am

    Hiya Jane! Would I be able to do the same recipe but in a 3lb tin? X

    • Jane's Patisserie on September 20, 2024 at 10:35 am

      You can, but as it’ll be thinner it will change the baking time x



  10. Alice hlland on August 15, 2024 at 10:09 am

    Hi Jane I have made this cake a lot of times and it’s amazing. But the butter cream icing keeps falling off the cake. Is there anything else I can do to make it stick thanks

    • Jane's Patisserie on August 21, 2024 at 9:21 am

      Oh no! This sounds like it could have actually split a bit – it’s worth adding a splash of milk or cream to bring it back and this should help x



  11. CC on July 27, 2024 at 11:18 am

    Can I use a Bundt tin instead of loaf tin?

  12. Robin P on July 24, 2024 at 6:51 pm

    Is soft brown sugar different than just any brown sugar?

    • Heather YKW on July 30, 2024 at 11:17 am

      I Googled, and it appears it’s just brown sugar, light or dark.

    Love Biscoff biscuits and these recipes sound delicious. I have a massive love at the moment for Biscoff Icecream, out of this world. I shall look forward to baking the Biscoff loaf and Biscoff little cakes.
    Well done Jane on your new recipe book.
