    Biscoff Cake Traybake

    Biscoff Cake Traybake

    When it comes to cakes, traybakes (also know as sheet cakes) are the easiest kind around! They are great for bake sales, parties and feeding a crowd. This Biscoff Cake Traybake is made with Biscoff spread and light brown sugar for a gorgeous caramelised sponge. It's topped with smooth Biscoff infused buttercream and a Biscoff biscuit on top. Absolute Biscoff heaven in every bite!

    Biscoff Cake Traybake

    Ingredient Tips & Equipment Information

    • Make sure all your ingredients (particularly the butter and eggs) are at room temperature before you start baking.
    • I used a baking spread for the cake and unsalted butter for the buttercream.
    • I used the smooth Biscoff spread for this recipe. You could use the crunchy one for the buttercream, just make sure if you are using a piping nozzle that it's fairly wide at the end so bits of biscuit don't get stuck in it.
    • I really recommend using light brown soft sugar if you can for the cake, but if you can't get hold of it, caster sugar will work well too.
    • 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.

    For the full recipe with measurements, head to the recipe card at the end of this post.

    How to make Biscoff Cake Traybake

    To make the cake, mix together the butter, sugar and Biscoff spread. Then whisk in eggs and milk.

    Add self raising flour and gently whisk in, then spread the mixture out into the tin.

    Bake the cake for 25-30 minutes or until golden brown and a thin skewer inserted in the centre comes out clean. Make the buttercream by mixing butter, icing sugar, Biscoff spread and milk together until smooth. Spread it over the cooled cake and decorate with Biscoff biscuits.

    For the full recipe with measurements, head to the recipe card at the end of this post.

    Biscoff Cake Traybake

    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 Cake Traybake last for and can you freeze it?

    The cake will last for 3-4 days in an airtight container in a cool place. You can freeze both the cake and the buttercream (but do not freeze the biscuits). To freeze them separately, wrap the cake well in cling film or put it in an airtight container. The buttercream can be frozen in a sealed tub. To freeze the cake decorated, freeze on a plate until frozen solid, then carefully wrap in cling film. Remove the clingfilm when you take the cake out of the freezer to defrost, as if it defrosts with it still on it could damage the buttercream.

    Can you make this cake with plain/all purpose flour?

    Self raising flour, which is very commonly used in the UK where I am based, already contains a raising agent and a little salt too. Therefore if you want to swap it for plain or all purpose flour, you will need to add some additional baking powder and also a little salt if you like. Some people like to add salt to cake recipes and some don't, so I'll leave that up to you as it won't affect the bake. The general advice is to add 2 teaspoons baking powder (a measuring teaspoon, not the kind you stir your coffee with) per every 200g plain or all purpose flour. So for this recipe you'd need to add 2 teaspoons baking powder. Please note, I have not tested this recipe using plain or all purpose flour.

    Biscoff Cake Traybake

    What size tin do you need for this cake?

    This recipe is best made in a 12" x 9" (36.5cm x 26cm) traybake tin with deep sides (4cm or 1.5"). However, if you'd prefer to make it in a smaller 9" square tin, check the recipe card notes section for details on how to change the measurements and baking time.

    How many people does this cake serve?

    It completely depends how you slice it up, which is great because it makes this such a versatile cake for parties and gatherings. I love a big chunk of cake so I cut it into 12 slices, but for a party you may prefer to cut it into smaller slices so it feeds more people. You can cut into 16 slices, or even 24 slices. If you are doing smaller slices, cut it up before you add the Biscoff biscuits on top so you don't have to try and cut through them.

    Can this cake be made gluten or dairy free?

    Yes, you can make the cake dairy free by replacing the butter and milk with dairy free versions. Unfortunately Biscoff spread is not gluten free, so you cannot make the loaf cake gluten free using Biscoff spread. If you are looking for an egg free recipe, check out my Vegan Biscoff Cake.

    Can this cake be made into cupcakes or a larger cake?

    Yes, to make this recipe into cupcakes check out my Biscoff Cupcakes recipe for details. Or for a larger cake you might like my Biscoff Cake or my Biscoff Drip Cake.

    More tips for making the Biscoff Cake Traybake:

    • You could also drizzle some melted Biscoff spread over the cake!
    • The biscuits will go soft after a few hours in contact with the buttercream, so add them to the cake as close to serving it as you can.
    • I spread the buttercream onto the cake, but you could pipe it on if you prefer.

    Ingredients

    For the cake

    • 225 g Butter or baking spread softened, unsalted
    • 225 g Light brown soft sugar
    • 100 g Biscoff spread smooth
    • 4 Eggs large
    • 1 tbsp Milk
    • 225 g Self raising flour

    For the buttercream

    • 150 g Butter softened, unsalted
    • 300 g Icing sugar
    • 200 g Biscoff spread smooth
    • 2-3 tbsp Milk

    For decoration

    • 12 Biscoff biscuits
    • 1 Biscoff biscuit crushed into crumbs
    Metric - US Customary

    Instructions

    • Pre-heat your oven to 160C Fan/180C/350F/Gas Mark 4, and grease and line a 12" x 9" traybake tin
    • Make the sponge by mixing the butter and light brown sugar in a large bowl until fluffy, ideally using an electric mixer
    • Add the Biscoff spread and mix in
    • Add the eggs and milk, and whisk until fully incorporated
    • Gently whisk in the self raising flour, and whisk in until you can't see any flour anymore
    • Pour the mixture into the tin, smooth it out of needed to spread it out evenly
    • Bake for 25-30 minutes or until a skewer inserted in the centre comes out clean. Leave to cool fully either in the tin or on a cooling rack
    • To make the buttercream, use an electric mixer to mix together the butter and icing sugar until they start to combine, then add the Biscoff spread and milk and mix until smooth. You can add more milk if the buttercream is too stiff
    • Spread or pipe the buttercream all over the cake
    • Decorate with the Biscoff biscuits (and a drizzle of melted Biscoff spread if you like). The biscuits will go soft after several hours in contact with the buttercream so add them later if you're not serving the cake straight away
    • To serve, slice into squares. Store any leftovers in an airtight container in a cool place and eat within 3 days

    Notes

    If you swap the self raising flour for plain/all purpose flour you will need to add 2 tsp baking powder.
    You can use caster sugar if you don't have light brown soft sugar.
    If you want to make this cake in a 9" square tin you will need:
    • 170g Butter or baking spread
    • 170g Light brown soft sugar
    • 75g Biscoff spread
    • 3 Large eggs
    • 170g Self raising flour
    It will take slightly longer to bake, check after 30 minutes and then check every 5 minutes until a thin skewer inserted in the centre comes out clean.

      How on earth did we manage for so long without Biscoff spread? I use it so often these days and have been known once or twice to take a huge spoonful straight from the jar!

      These are absolutely delicious !!! The sponge was super easy to make. I baked it for 25-minutes in a fan oven at 160C and it worked a treat. The cake itself is super moist. Will definitely be making this beauty again !!! 🙂
