    Ah Biscoff. Also called Lotus Biscoff, they are little biscuits of spiced caramelized deliciousness. Commonly known as speculoos, these Belgium cookies have become hugely popular around the world and has developed somewhat of a cult following. These tasty little morsels are commonly available as a spread, making it perfect for flavoring cheesecake, ice cream and in this case, cakes and buttercream.

    This Lotus Biscoff spread cake is the stuff Biscoff dreams are made of. A simple, moist, velvety cake with Biscoff spread and buttermilk to balance the sweetness. Serve it with lashings of my Biscoff buttercream for a show-stopping dessert that will impress every time!

    Hungry for more Biscoff desserts (and let's face it who isn't??). I've got you covered! Why not try making my Biscoff cheesecake, Biscoff ice cream, Biscoff rocky road or Biscoff cinnamon rolls. Delicious!

    Tips and frequently asked questions

    How does Lotus Biscoff Cake taste?

    Lotus Biscoff cake unsurprisingly tastes like Biscoff! A sort of spiced, cinnamon caramel flavor just like the cookies. It's best to use smooth Biscoff spread when baking cakes for a lovely fine crumb. You can use crunchy Biscoff spread if that's all you have but your cake crumb will be coarser.

    What is Biscoff Cake made of?

    Biscoff cake is usually made of cake ingredients such as flour, sugar, eggs, butter and of course Biscoff! Biscoff speed makes it easy to flavor the cake while keeping a lovely fine velvety crumb. Excellent with a little buttermilk to balance the sweetness of the Biscoff.

    Ingredients

    For the Biscoff Cake

    Cake ingredients as listed in text.

    Biscoff spread: available from some supermarkets, specialty stores and online. This cake works with either smooth or crunchy spread, but you will get a lighter, finer crumb with smooth. If you can't get Lotus Biscoff spread you can try another brand of cookie butter spread.

    Brown sugar: also called light brown sugar, helps to give these brownies some extra caramel notes. You could use dark brown sugar for some extra caramel notes, or white sugar or demerara sugar. If using cups to measure the brown sugar make sure its packed down firmly (and ideally use a kitchen scale).

    Vanilla extract: sometimes also called vanilla essence, depending on where you live. You can use either, or imitation vanilla essence, depending on your preference and budget.

    Plain flour: is best in this recipe. You can also use all-purpose flour. It's important to use flour that does not have any rising agents as we will be adding our own in the right amounts to help this cake rise.

    Corn flour: also known as corn starch and can be labeled as wheaten cornflour or corn (maize). The cornflour makes the cake crumb softer and makes for a lighter, velvety cake.

    Baking powder: is a common ingredient in cakes and baking, used to help the cake rise. For the best results use fresh baking powder and not one that's been sitting around the cupboard for a while.

    Baking soda: also known as bicarbonate soda or bicarb. This is NOT the same as baking powder and you can not substitute this.

    Milk: full cream milk is best for this recipe. I rarely have buttermilk in the house but it's so easy to make your own with milk and a little lemon juice. You could use buttermilk instead if you prefer.

    Lemons: a dash of lemon juice is used to make the homemade buttermilk. Fresh is best, I don't recommend bottled lemon juice.

    Butter: unsalted butter is best or your risk your cake being too salty. It's important your butter is a room temperature before you start baking so your batter comes together and your cake rises.

    Vegetable oil: adds some much-needed fats to this cake and helps keep the crumb nice a fine. You can try substituting with similar oils such as peanut or canola.

    Eggs: I use large eggs in this recipe, approx. 55 gms each with shells before cracking.

    For the Biscoff Buttercream

    Ingredients: Biscoff spread, vanilla extract, lemon juice, milk, icing/powdered sugar, salt, unsalted butter.

    Biscoff Spread and vanilla extract: as for the cake

    Icing sugar: also known as powdered sugar, it's a key ingredient in this cookie butter buttercream.

    Unsalted butter: it's not buttercream without butter! The butter helps bind and set the buttercream. Make sure your butter is at room temperature before starting.

    Lemons: a dash of lemon juice helps balance the sweetness of the buttercream. Fresh is best, I don't recommend bottled lemon juice. For sweeter buttercream replace some of the lemon juice with milk.

    Milk: a little milk helps loosen up the buttercream and make it workable. For less sweet buttercream replace some of the milk with lemon juice.

    Salt: a little salt helps balance the sweetness of this buttercream.

    How to make Biscoff cake

    See the full recipe card at the end of the post for ingredient amounts and instructions.

    To make the cake:

    Hot tip: If you are making the brown butter to go with the buttercream make this now so it can cool while your cakes bake.

    Preheat your oven to 365°F (185°C/165°C fan-forced). Grease and line 2 x 8inch round cake tins baking paper. To make the buttermilk measure out the milk and add the lemon juice. Allow to stand at room temperature until you need it.

    Process shots: greasing and lining tins, adding lemon juice to milk for buttermilk, adding Biscoff spread, adding eggs.

    Cream the room temperature butter and brown sugar together in a stand mixer on medium until fluffy. Add the Biscoff spread and mix well. Add the vanilla extract and eggs and mix well.

    Sift in the flour, cornflour, salt, baking soda and baking powder. Add the buttermilk. Fold in gently together until just combined and there are no unmixed lumps of flour.

    Process shots: sifting flour, adding buttermilk, adding rest of flour, pouring batter into cake tins.

    Divide between two lined cake tins and bake for 35 mins or until a toothpick inserted comes out clean and the cake is no longer 'talking'.

    Allow to cool before removing from the cake tins. Allow cakes to cool completely before frosting or your frosting will melt!

    To make the buttercream and decorate the cake:

    Cub the butter for the buttercream and add to a light-colored pan. Heat on medium-high until melted and foaming. Continue to stir until butter starts to brown and develops a wonderful nutty aroma.

    Process shots group 1: adding cubed butter to medium light colored saucepan, foaming butter with big bubbles, pouring browed butter into heatproof bowl, room temperature brown butter ready to beat.

    Remove from heat and transfer to a heatproof container immediately, taking care to scrape out the brown bits at the bottom (that's where all the flavor is). Chill in the fridge until solidified. Then remove and return to room temperature. You need the butter at room temperature to make the cookie butter frosting.

    Add the brown butter to a stand mixer or bowl, making sure you include all the brown bits at the bottom.

    Process shots group 2: adding Biscoff spread, sifting in icing sugar, adding lemon juice, adding milk.

    Add the Biscoff spread and cream the brown butter and Biscoff spread together in the stand mixer or with electric handheld beaters. Sift in the icing sugar and salt. Add the lemon juice and milk. Beat on medium until fluffy and well combined.

    Put your first cake onto a serving plate or cake stand. Cover the top of the cake with frosting. If you want, flip the top cake over so the 'base' becomes the nice flat top of the cake. This saves trimming your cake to get a perfectly flat top. You will end up with a small gap at the edges in the middle of the cake, but this will not be visible as we are frosting the cake.

    Frost the top can sides of the cake, filling in any gap in the middle and then smoothing down with an offset spatula. Sprinkle with some extra crushed-up Biscoff biscuits and you're done!

    Decorating cake: adding frosting to first layer, adding frosting to second layer, sprinkling on biscuit crumbs.

    For something truly spectacular you could add a Biscoff drip like the one on my Biscoff cheesecake. Microwave about ⅓ of a cup of Biscoff Very briefly in the microwave, add to a piping bag or zip lock bag with the corner cut off.

    Carefully pipe around the edge of the cake, squeezing out extra drips, then moving a little bit along and making the next drip. It's important the Biscoff spread isn't too hot or it will slide all the way down the cake. (I was totally going to do this before I photographed the cake, but I think it got distracted by my kids! I may yet remake it and update the photos :D)

    How to serve

    Slicing cake.
    Serving Biscoff Cake.

    To serve this Biscoff spread cake pop onto a plate, slice and enjoy! Fabulous with a cup of tea or coffee for morning or afternoon tea. Delicious!

    How to store

    This cake will store in a covered container on the bench for up to three days. It does not need to be refrigerated. The buttercream will last on its own for up to one month in the fridge.

    Can you freeze Biscoff cake?

    Yes you can freeze this cake, either frosted or unfrosted. To freeze unfrosted wait until the cakes are completely cool, then wrap individually in cling film and foil and freeze in an airtight container.

    You can freeze the cake once decorated. Again carefully wrap in cling film and store in an airtight container. If you are going to do this make sure you remove the cling film Before defrosting or you risk damaging the decoration. Defrost in the fridge overnight before serving. This will take up a lot of space in the freezer.

    The buttercream itself also stores well in the fridge for up to one month or up to three months in the freezer in an airtight container. You may need to add a little milk to loosen up the buttercream before frosting the cake.

      Notes

      • The recipe time given is the hands-on time to make the cake.  It does not include cooling time for the cake or chilling time for the brown butter for the buttercream. 
      • If making this cake in advance hold off sprinkling on the crushed-up biscuits until right before serving, or they will go soft.   
      Storage: 
      This cake will store in a container on the bench for up to three days.  It does not need to be refrigerated.  The Biscoff buttercream will store well in an airtight container on its own in the fridge for up to one month.  
      Freezing: this cake can be frozen for up to a month, either frosted or unfrosted.  Wrap completely cool unfrosted cakes in cling film then foil and store in an airtight container in the freezer.   If freezing frosted wrap do not add the biscuit crumb yet as they will go soft.  Carefully in cling film on the plate or cake board.  Remove cling film Before defrosting or it may stick to the frosting.  It will take up a lot of room in the freezer this way.  Add the biscuit crumb just before serving.

        Hi, I am trying out this recipe and noticed that you have put oil in the ingredient list but there is no instruction where to place it.
        I've read the recipe a few times and can't see it. Please advise if it's needed.

          Hi Nancy, apologies for that. Yes the oil is needed, 1/4 cup per the ingredients list, to be added with the vanilla extract and eggs. I'll update the recipe card now, let me know how it goes 🙂

        Hi there,
        I plan on making your delicious biscoff cake for my husband’s birthday but will need to tweak it to suit his dietary requirements…
        Will the nuttelex be ok to clarify??
        And i’m guessing i just omit the salt, if it already has it or do i reduce the amount?
        Thank you

          Hi Helen,
          When I am doing dairy-free baking I tend to use nuttelex butterly, so I imagine this would be an OK substitute. The amount of salt you are adding with nuttelex butterly vs unsalted butter is less than half a gram. So I would add a bit less than 1/2 teaspoon of salt to the cake batter, and a bit less than 1/4 teaspoon of salt to the buttercream.
