Biscoff Tiramisu with a Crunchy Chocolate Shell

Have you ever tried tiramisu with a chocolate shell that you can crack open with a spoon?

That’s exactly what makes this Biscoff Tiramisu so satisfying!

Instead of using traditional ladyfingers, I made this tiramisu with Lotus Biscoff cookies, fluffy mascarpone cream, a rich cookie butter topping, and a thin layer of crunchy dark chocolate.

The Biscoff cookies gradually absorb the coffee and become soft and cake-like, while the mascarpone cream adds a light, creamy texture.

But here’s my favorite part: the chocolate shell on top!

When you tap it with a spoon, it cracks into thin chocolate pieces, revealing the creamy layers underneath.

You get crunchy chocolate, smooth cookie butter, fluffy mascarpone cream, and coffee-soaked Biscoff cookies all in one bite!

And the best part? You don’t even need an oven to make this dessert!

What Is Biscoff Tiramisu?

Traditional Italian tiramisu is usually made with coffee-soaked ladyfinger cookies, mascarpone cream, and a dusting of cocoa powder.

But I wanted to try something a little different.

What if we replaced the ladyfingers with Biscoff cookies and added a crunchy chocolate topping?

Biscoff cookies are thin, crispy, caramelized biscuits with a warm, slightly spiced flavor.

They taste delicious on their own, but when paired with coffee, they become even better!

As the cookies absorb moisture from the coffee and mascarpone cream, they gradually soften into delicate, cake-like layers.

I also added a layer of Biscoff cookie butter spread on top of the mascarpone cream.

It gives the tiramisu an extra boost of caramelized cookie flavor and creates a smooth layer between the cream and chocolate shell.

Finally, instead of dusting the tiramisu with cocoa powder, I covered the entire surface with melted dark chocolate.

After chilling, the chocolate forms a thin shell that cracks beautifully when you press it with a spoon.

It’s almost like a giant chocolate-covered tiramisu!

Why Use Biscoff Cookies Instead of Ladyfingers?

Ladyfingers are the traditional choice for tiramisu because their light, sponge-like texture absorbs coffee easily.

Biscoff cookies are quite different.

They’re thinner, denser, and much crispier, with a delicious caramelized flavor.

I love using them because their sweetness pairs perfectly with the slight bitterness of coffee.

However, there’s one important thing to remember.

Biscoff cookies soften much faster than traditional ladyfingers!

If you soak them in coffee for too long, they can become soggy or even break apart before you finish assembling the tiramisu.

That’s why I use a slightly different dipping method.

My Trick for Perfect Coffee-Soaked Biscoff Cookies

Instead of dipping the entire cookie into coffee, I only quickly dip one side.

Then I place each cookie in the baking pan with the coffee-dipped side facing up.

The coffee gradually soaks through the cookie as the tiramisu chills.

This way, the cookies can absorb enough coffee without becoming overly wet during assembly.

And trust me, you don’t need to soak them for long!

A very quick dip is enough.

After several hours in the refrigerator, the cookies will soften into delicious, cake-like layers.

Ingredients

This Biscoff tiramisu is made with four main components.

1. Mascarpone Cream

• 4 large pasteurized egg yolks: If you can’t find pasteurized eggs, check out my step-by-step guide on how to pasteurize regular eggs at home to reduce the risk of Salmonella.
• 50 g granulated sugar: Adds sweetness and helps create a thick, fluffy egg yolk mixture.
• 450 g mascarpone cheese: The main ingredient that gives tiramisu its signature creamy texture.
• 300 g heavy whipping cream: Makes the filling lighter and fluffier.

2. Biscoff Cookie Layers

• 250 g Lotus Biscoff cookies: Replace traditional ladyfingers with a delicious caramelized cookie flavor.
• 200 ml strong brewed coffee or espresso: Balances the sweetness of the cookies and cream.

I recommend using strong coffee because the Biscoff cookies and cookie butter are already quite sweet.

The slightly bitter coffee helps balance the overall flavor.

Make sure the coffee has cooled completely before dipping the cookies.

3. Biscoff Topping

• 80 g Biscoff cookie butter spread

Biscoff cookie butter spread has a thick consistency, so I like to microwave it for about 10–15 seconds until smooth and pourable.

This makes it easier to spread evenly over the mascarpone cream without adding any extra ingredients.

Let it cool slightly before pouring to prevent the mascarpone cream from melting. Once refrigerated, it forms a delicious cookie butter layer underneath the crunchy chocolate shell.

Don’t have Biscoff spread at home? You can use caramel sauce instead! It adds a similar sweet, caramel-like flavor and works just as well as a topping.

4. Chocolate Shell

• 120 g dark chocolate
• 15 g coconut oil

The dark chocolate adds a slightly bitter flavor that balances the sweetness of the Biscoff cookies.

Coconut oil helps thin the melted chocolate, making it easier to spread into a thin, even layer.

Once chilled, the chocolate forms a firm shell that cracks when you tap it with a spoon.

And that’s the most satisfying part of this dessert!

Equipment

• 9 × 7-inch metal baking pan
• Electric hand mixer
• Large mixing bowls
• Silicone spatula

How to Make Biscoff Tiramisu

Step 1: Make the Mascarpone Cream

Start by adding 4 large egg yolks and 50 g granulated sugar to a mixing bowl.

Using an electric hand mixer, beat the mixture for about 3 minutes until it becomes pale, thick, and fluffy.

Important: For food safety, use pasteurized eggs. If you’re using regular eggs, gently heat the egg yolks and sugar over a hot water bath to 160°F (71°C) before whipping. Alternatively, check out my guide to pasteurizing eggs at home to help reduce the risk of Salmonella.

Once the egg yolk mixture is ready, add 450 g mascarpone cheese.

Mix on low speed until smooth and creamy.

Avoid overmixing because mascarpone can become grainy or separate if beaten too aggressively.

In a separate bowl, whip 300 g cold heavy whipping cream until soft peaks (When you lift the beaters, the cream should form soft peaks that droop downward and gently wobble when you move the beaters) form.

Gently fold the whipped cream into the mascarpone mixture until everything is evenly combined.

Now we have a deliciously fluffy mascarpone cream!

Step 2: Prepare the Coffee-Soaked Biscoff Cookies

Brew 200 ml strong coffee or espresso and let it cool completely.

Prepare a metal baking pan, mine is 9x7x2″.

Now comes an important step!

Take one Biscoff cookie and quickly dip only one side into the coffee.

Immediately place it in the baking pan with the coffee-dipped side facing up.

Repeat until the bottom of the pan is covered with a single layer of cookies.

Don’t worry if the cookies still feel crispy at this point.

The coffee will gradually soak through them, and they’ll continue softening as the tiramisu chills.

Avoid soaking the cookies for too long!

Unlike traditional ladyfingers, Biscoff cookies can become soggy and fall apart very quickly.

Step 3: Assemble the Tiramisu

Once the first layer of cookies is ready, spread half of the mascarpone cream evenly over the top.

Use a silicone spatula to gently smooth the surface.

Next, add another layer of coffee-dipped Biscoff cookies.

Remember to keep the dipped sides facing up!

Spread the remaining mascarpone cream over the second cookie layer.

Smooth the surface as evenly as possible.

Now we have two layers of coffee-soaked Biscoff cookies and two layers of fluffy mascarpone cream.

But we’re not finished yet!

Step 4: Make the Biscoff Topping

Place 80 g Biscoff cookie butter spread in a microwave-safe bowl.

Microwave for about 10–15 seconds until smooth and pourable. Stir well.

Let it cool slightly before pouring it over the mascarpone cream. You don’t want the warm topping to melt the cream underneath!

Gently tilt the baking pan to spread the Biscoff topping into a thin, even layer.

This creates a delicious layer of cookie butter between the fluffy mascarpone cream and crunchy chocolate shell.

Don’t have Biscoff spread? You can use caramel sauce instead!

Step 5: Make the Crunchy Chocolate Shell

Add 120 g dark chocolate and 15 g coconut oil to a microwave-safe bowl.

Microwave in 20-second intervals, stirring between each interval, until completely melted and smooth.

Let the chocolate cool until just slightly warm.

Then slowly pour it over the Biscoff topping.

Gently tilt the pan to spread the chocolate into a thin, even layer.

Try to cover the entire surface.

The thinner the chocolate layer, the easier it will be to crack with a spoon!

Step 6: Chill and Enjoy!

Cover the tiramisu and refrigerate for at least 6 hours, preferably overnight.

During this time, the Biscoff cookies gradually absorb the coffee and moisture from the cream.

The mascarpone filling becomes firmer, and the chocolate topping sets into a crunchy shell.

When you’re ready to serve, take the tiramisu out of the refrigerator.

Now comes my favorite part!

Grab a spoon and gently tap the chocolate surface.

Crack!

The thin chocolate shell breaks into little pieces, revealing the creamy Biscoff tiramisu underneath.

Scoop through all the layers and enjoy!

Tips for Perfect Biscoff Tiramisu

1. Don’t Oversoak the Biscoff Cookies

This is probably the most important tip for this recipe.

Biscoff cookies are much thinner than traditional ladyfingers.

If you dip them completely into coffee and leave them there for too long, they can become too soft and break apart.

I recommend quickly dipping only one side and placing the cookies with the wet side facing up.

The coffee will gradually soak through the cookies as the dessert chills.

You want soft, cake-like layers, not mushy cookies!

2. Don’t Overmix the Mascarpone

Mascarpone cheese is rich and creamy, but it can separate if overmixed.

I recommend letting it sit at room temperature for about 10–15 minutes before using.

It should be slightly softened but still cool.

When combining it with the egg yolk mixture, use low speed and stop mixing as soon as everything is smooth.

After adding the whipped cream, use a spatula to gently fold everything together.

This helps keep the filling light and fluffy.

3. Use Pasteurized Eggs for Food Safety

Traditional tiramisu often contains raw egg yolks, so I recommend using pasteurized eggs to reduce the risk of Salmonella.

Can’t find pasteurized eggs at your local grocery store? You can make them at home!

Check out my step-by-step guide on how to pasteurize eggs at home. I use a temperature-controlled water bath at 135°F (57°C) for 75 minutes to gently heat whole eggs without fully cooking them.

If you prefer not to use raw egg yolks, you can also gently heat the egg yolks and sugar over a hot water bath until the mixture reaches 160°F (71°C). Whisk constantly and use a food thermometer to prevent the eggs from scrambling.

Proper pasteurization helps reduce the risk of Salmonella, although no home method can guarantee completely risk-free raw eggs.

4. Work Quickly with the Biscoff Topping

The melted Biscoff spread will thicken quickly as it cools, making it harder to spread evenly.

Once the Biscoff spread is warm and pourable, immediately pour it over the mascarpone cream.

Quickly but gently tilt the baking pan from side to side to spread the Biscoff topping into a thin, even layer.

Work fast before the Biscoff spread cools and thickens, but be gentle to avoid disturbing the fluffy mascarpone cream underneath.

5. Make the Chocolate Shell Thin

The chocolate shell is what makes this tiramisu extra satisfying!

I use 120 g dark chocolate and 15 g coconut oil for my 9.5 × 7.5-inch baking pan.

The coconut oil helps the melted chocolate spread more easily and creates a thinner shell.

If you prefer a firmer chocolate topping, you can omit the coconut oil.

For the best cracking effect, try to spread the chocolate as evenly and thinly as possible.

6. Refrigerate Overnight for the Best Texture

Although this tiramisu can set in about 6 hours, I recommend refrigerating it overnight if you have time.

The extra chilling time allows the coffee to gradually soften the Biscoff cookies.

It also helps the mascarpone cream become firmer and makes the layers easier to scoop.

Plus, it’s a perfect dessert to prepare the day before a party!

7. Choose the Right Baking Pan

I used a 9× 7-inch metal baking pan for this recipe.

The rectangular shape makes it easy to arrange the Biscoff cookies in neat layers.

Depending on how tightly you arrange them, you may need slightly more or fewer cookies than the 250 g listed in the recipe.

You can also use a similar-sized glass or ceramic baking dish.

Frequently Asked Questions

Can I Make Biscoff Tiramisu Without Eggs?

Yes!

If you prefer an egg-free version, you can omit the egg yolks and sugar and make a simple mascarpone whipped cream filling instead.

Whip the mascarpone with powdered sugar to taste, then gently fold in the whipped heavy cream.

The texture will be slightly different from the original recipe, but it will still be creamy and delicious.

Can I Use Decaf Coffee?

Absolutely!

Decaf coffee works just as well as regular coffee.

You’ll still get that delicious coffee flavor without as much caffeine.

Just make sure to brew it strong enough to balance the sweetness of the Biscoff cookies.

Can I Use Milk Instead of Coffee?

Yes, you can use milk, or strawberry milk, if you don’t like coffee.

However, the tiramisu will taste sweeter and won’t have the traditional coffee flavor.

I personally prefer strong coffee because its bitterness balances the sweet caramelized Biscoff flavor.

Can I Use White Chocolate Instead of Dark Chocolate?

Yes!

White chocolate would make this dessert even sweeter and creamier.

However, because Biscoff cookies and cookie butter are already quite sweet, I prefer dark chocolate.

The slight bitterness of dark chocolate creates a better balance of flavors.

How Long Does Biscoff Tiramisu Last in the Refrigerator?

Keep the tiramisu covered in the refrigerator at 40°F (4°C) or below for up to 3 days.

For the best texture, I recommend enjoying it within 1–2 days.

The cookies will continue absorbing moisture over time, so the layers may become softer the longer you store it.

Why Is My Chocolate Shell Too Hard to Crack?

If the chocolate layer is too thick, it can become difficult to break with a spoon.

Try spreading the melted chocolate into a thinner layer next time.

Adding coconut oil also helps make the chocolate easier to spread.

You can let the tiramisu sit at room temperature for about 5 minutes before serving to make the shell slightly easier to crack.

Final Thoughts

If you love Biscoff cookies, coffee, and creamy desserts, you have to try this tiramisu!

I love how the caramelized Biscoff flavor pairs with the rich mascarpone cream and slightly bitter dark chocolate.

And of course, cracking the chocolate shell is almost as satisfying as eating the dessert itself!

It’s creamy, crunchy, sweet, and full of delicious coffee and cookie butter flavor.

Just remember to dip those Biscoff cookies quickly and give the tiramisu enough time to chill.

The result is a delicious homemade Biscoff tiramisu with beautiful layers and a satisfying chocolate crunch in every bite!
