📖 What are Biscoff and Biscoff spread
Biscoff is the familiar name of Belgian speculoos cookies (spiced cookies) produced by Lotus Bakeries. If someone says they're looking for Biscoff at a store, most possibly they're referring to Lotus Biscoff Cookies. Biscoff cookies have crunchy textures and they're loaded with sweetness, caramel flavor, and a hint of spice. It's vegan and dairy free.
After the original Biscoff biscuit gained international fame, the company launched a new product called Lotus Biscoff Cookie Butter (also known as Lotus Biscoff spread or Speculoos Cookie Butter). It's basically a cookie spread that is made of Biscoff cookies and several other ingredients. It looks like peanut butter but it tastes so much like Biscoff cookies. No Biscoff spread in your pantry?

📝 Ingredient notes
This is a from-scratch recipe. Making Biscoff cupcakes with cake mix doesn't guarantee a moist result so it's better to start from scratch especially as it is soo easy! If you decide to substitute one of the main ingredients, you may need to adjust the other ones.
For the Brown sugar Cupcakes
- Butter: Use unsalted butter in this baking recipe so you can have control over the saltiness level of the batter. I prefer using butter with 82% fat content for my recipes. Also, remember to keep the butter soft at room temperature (not cold).
- Sugar: For this easy Biscoff cupcake recipe, I use a combination of granulated white sugar and brown sugar! For brown sugar, remember that light brown sugar has a lighter flavor than dark brown sugar. Read my sugar guide to learn more.
- Flour: Use all purpose flour to make these Biscoff cupcakes. Don't forget to sift it to avoid any lumps in the batter. You can sift it together with other dry ingredients. Read my flour guide to learn more.
- Cinnamon: It enhances the nice spicy flavor coming from the Biscoff spread filling.
- Baking powder: It helps increase the volume of the cupcake. You will need a little amount of it, about ½ teaspoon baking powder.
- Salt: You will need a little amount of it, but it's essential! It balances the flavor and sweetness of this cupcake.
- Milk: Use whole milk at room temperature.
- White vinegar + baking soda: This combo is the secret addition making crazy moist tender Biscoff cupcakes!

For the Biscoff buttercream frosting (cookie butter frosting)
This is a Biscoff-flavored German buttercream frosting (also called mousseline cream), the most delicious frosting that you will ever make! Mousseline cream is a pastry cream-based frosting that is enriched with butter and Biscoff spread, absolutely out of this world!
- Milk: Use whole milk at room temperature to make the pastry cream
- Sugar: Buttercream frosting usually use powdered sugar or icing sugar. However, this mousseline frosting will need regular white granulated sugar instead
- Egg: Use egg yolk only to achieve the best texture and flavor of the pastry cream.
- Cornstarch: It helps build consistency. The more you add this, the thicker the cream will be.
- All-purpose flour: All-purpose flour also helps build consistency. Don't worry, it won't taste like flour!
- Butter: Use soft, unsalted butter at room temperature. If the butter is too cold, it can be hard to combine. If the butter is in liquid form, the cream can get runny. The butter is a super important ingredient in this frosting. It will be used to make the pastry cream and to convert the pastry cream into mousseline cream.
- Biscoff spread: This recipe is about Biscoff cupcakes with Biscoff buttercream, so Biscoff cookie butter spread is a very special ingredient here! You can buy it or you can make it at home using my homemade Lotus Biscoff butter recipe. It has a combination of sweetness and caramel flavor plus a hint of cinnamon spice. Super delicious!

👩🍳 How to make this recipe
1. How to make moist brown sugar Cupcakes
First of all, it's always a good idea to prepare your ingredients precisely using a digital scale.
The next thing to do is to prepare the oven. Preheat your oven to 175 degrees Celsius or 347 degrees Fahrenheit (no fan).
Then, follow these steps:
- Mix the butter and sugar using an electric hand mixer. It can take up to several minutes until it gets fluffy. After that, add egg and continue whipping until they're combined well.
- In a separate bowl, sift flour, salt, cinnamon, and baking powder together (dry ingredients)
- Mix half of the room temp milk into the whipped butter mixture using a rubber spatula.
- Mix in half of the sifted dry ingredients to the whipped mixture.
- Add the remaining milk to the mixture. Then, add the remaining dry ingredients. Mix them well.
- In a new small bowl, mix the vinegar and baking soda. It might be bubbly but don't worry. Immediately, transfer this liquid into the batter. Continue mixing the butter until it's well-combined.
- Grab your cupcake pan. Line them with cupcake liners.
- Pipe the batter into the cupcake cups (or use a spoon). Each cup should be filled up to ¾ full, not more.
- Bake the cupcakes at 175 C/ 347 F (no fan) for about 25 minutes
- During the final minutes, check the inner part of the cupcake by inserting a toothpick. If it comes out clean, it means that the baking is complete. So, take out your cupcakes immediately and let them cool down in a cooling rack.
💡 Top Tip: Remember to only use room temperature ingredients, including eggs, butter, and milk. This will help the ingredients to properly emulsify.
2. How to make Biscoff buttercream frosting
It's not the typical American frosting. It tastes so much butter and the texture is amazing! The first part of this process is making pastry cream. After that, you can quickly turn it into mousseline cream aka German buttercream.
Follow these steps to make the pastry cream:
- Grab a large mixing bowl and a hand whisk. Mix the egg yolk and sugar for about 1-2 minutes until it looks slightly fluffy.
- Add the corn starch and flour. Mix them well until it looks like a smooth paste. Set aside.
- Grab a saucepan and use it to simmer the milk over medium heat. Do not let it boil.
- Gradually, pour the warm milk into the paste-like mixture while keep whisking vigorously.
- Pour the mixture into the saucepan and simmer over medium heat. Keep whisking while cooking it. It should take several minutes until it thickens.
- Strain the cooked mixture (the cream) to avoid any lumps.
- Gradually, add soft butter (not cold) to the cream. Mix well with a rubber spatula until well combined.
- Transfer the cream to a shallow bowl. Cover it with a plastic wrap and let it cool at room temperature.
Once your pastry cream reached room temperature, it's ready to convert into a mousseline. Follow these steps:
- Make sure that the pastry cream has really cooled down at room temperature and grab the butter and make sure it's room temperature too
- It's time to use your stand mixer. Whip the butter for several minutes until it's fluffy using the whisk attachment.
- When your butter looks pale and creamy, mix in the Biscoff spread. Keep mixing.
- Then, gradually mix in the pastry cream. You can do this in 4 batches. Wait for the previous batch to combine and add the next one.
- Continue mixing for about 1-2 minutes until it becomes fluffy. Once it reaches a pipeable consistency, stop the mixer right away. Do not overmix as it can get runny.
- Transfer the mousseline cream to a piping bag and keep it in the fridge for about 30 minutes before piping for the best consistency.
💡 Top Tip: Pay attention to the temperature of the ingredients when making mousseline cream. Both the butter and pastry cream must be at room temperature so they can mix beautifully.
3. How to assemble
After the cupcakes come out of the oven, let them cool down. Then, follow these steps:
- Poke a small hole in your cupcakes to put the filling. You can do this with a knife
- Fill the hole with Biscoff spread
- Decorate the cupcake! Use the Biscoff buttercream to pipe onto the cupcakes! You can also use Biscoff spread and Biscoff cookies to decorate the cupcakes!
At this point, your Biscoff cupcakes with Biscoff buttercream should be ready! You can serve them immediately or you can keep them in a closed container refrigerated for 2-3 days! For more information read my how to store and freeze cupcakes baking guide.
💡 Top Tip: Right after preparing the frosting, you can either immediately use it or sightly further chill it in the fridge. When the cupcakes are ready to decorate, take out the frosting and test the consistency on a plate first. Too runny? Chill it further! Too hard? Let it slightly warm at room temperature!
🥣 Equipment Notes
First, you will need a digital kitchen scale to measure the ingredients precisely if you want to set yourself up for success making these Biscoff cupcakes with Biscoff buttercream!
After mixing the batter well, pour it into the cupcake tin. Of course, you will need to layer it with cupcake cups before pouring the batter.
After filling your cupcake pan, check the oven temperature first. Most often, the oven displays incorrect temperatures which can lead to a problem in the baking process. Hence, it's a good idea to use a digital oven thermometer.
🎓 Expert tips
- For the Biscoff cupcake, make sure that all ingredients are at room temperature so you can easily mix them. Cold ingredients can prevent or ruin emulsification.
- Avoid overmixing. Mix the dry ingredients and wet ingredients until just combined.
- Fill your cupcake tin carefully until it reaches ¾ full. Avoid overfilling. This is a tall cupcake recipe. If you decide to overfill the cupcake tin, it may end up with mushroom-type cupcakes instead.
- Let the cupcakes cool down before frosting.
- For the mousseline cream, pay attention to the temperature. Make sure that the pastry cream and the butter need to reach room temperature.
- This recipe uses Biscoff spread in the buttercream mixture. However, feel free to get creative, and replace the Biscoff spread with another flavoring agent such as Nutella or Hazelnut paste. Just be careful and try to adjust the sugar during the mixing process.
Yes, you can! However, if you're a huge fan of Lotus Biscoff and decided to make a cake instead, consider my Lotus Biscoff Cake recipe.
Biscoff cookie buttercream tastes like Biscoff spread, except that it's more creamy, fluffy and so much softer!
Yes, you can do that! You can adjust the color of Biscoff buttercream according to your need! I suggest using good quality concentrated gel or powder food coloring as liquid food coloring might not be strong enough and ruin the consistency of your frosting.
It is not ideal to freeze this custard-based Biscoff buttercream and most certainly freezing will impact its texture.
You can keep these Biscoff cupcakes refrigerated for 2-3 day in an airtight container. It needs to be perfectly covered to keep the moisture and to avoid contamination.
Carefully arrange the cupcakes in an airtight container but without the frosting on. If stored properly, it should last for about 2-3 months inside the fridge.
