Step-by-Step Instructions
Follow these detailed steps to create perfect Lotus Biscoff Brownies every time:
Preparation:
- Preheat your oven to 350°F (180°C).
- Line your baking pan with parchment paper, leaving some overhang on the sides for easy removal.
- Measure all ingredients to have them ready (mise en place).
Making the Brownie Base:
- In a medium saucepan over low heat, melt the dark chocolate and butter together, stirring occasionally until completely smooth.
- Remove from heat and let cool for 5 minutes.
- Add the sugar to the chocolate mixture and whisk until well incorporated.
- Add eggs one at a time, whisking well after each addition.
- Stir in the vanilla extract.
- Sift together the flour, cocoa powder, and salt.
- Gently fold the dry ingredients into the chocolate mixture until just combined (don’t overmix).
- Fold in the crushed Biscoff cookies, reserving a small handful for the top.
- Pour about ¾ of the brownie batter into the prepared baking pan, spreading it evenly.
Creating the Biscoff Swirl Layer:
- In a separate bowl, whisk together the Biscoff spread, powdered sugar, and egg until smooth.
- Carefully spread this mixture over the brownie batter in the pan.
- Dollop the remaining brownie batter on top in several spots.
- Use a knife or skewer to create swirls, being careful not to overmix the layers.
Adding the Topping:
- Drizzle the warmed Biscoff spread over the top of the brownie batter.
- Use a knife to create more swirls on the surface.
- Sprinkle the remaining crushed Biscoff cookies over the top.
- If using, add a light sprinkle of sea salt flakes.
Baking:
- Bake in the preheated oven for 25-30 minutes. For fudgy brownies, a toothpick inserted should come out with a few moist crumbs (not completely clean).
- Place the pan on a cooling rack and allow the brownies to cool completely in the pan (at least 1 hour).
- Once cooled, lift out using the parchment paper overhang and cut into squares.
The Science Behind Perfect Brownies
Understanding the science of brownie-making can help you achieve better results. Here’s a detailed breakdown:
| Factor | Role in Brownies | Impact on Lotus Biscoff Brownies |
|---|---|---|
| Fat Content | Provides moisture and richness | The combination of butter and Biscoff spread creates an ultra-moist texture |
| Sugar Type | Affects sweetness and texture | Granulated sugar in brownies creates that classic crackly top |
| Chocolate Quality | Determines depth of flavor | Higher cocoa percentage (70%) balances the sweetness of Biscoff |
| Egg Function | Provides structure and richness | The extra egg in the Biscoff layer helps it maintain distinct swirls |
| Baking Time | Determines fudginess vs. cakiness | Slightly underbaking (25-28 minutes) yields the perfect fudgy center |
| Cooling Time | Allows for full flavor development | At least 1 hour cooling lets the Biscoff flavors fully integrate |
| Flour Ratio | Affects density and chewiness | The moderate flour amount (130g) ensures the perfect chewy texture |
Troubleshooting Common Issues
Even experienced bakers sometimes encounter challenges. Here are solutions to common Biscoff brownie problems:
Too Cakey Instead of Fudgy
- Reduce flour by 20g in your next batch
- Check your oven temperature with an oven thermometer
- Reduce baking time by 3-5 minutes
Biscoff Flavor Not Pronounced Enough
- Increase the amount of crushed cookies in the batter
- Add 2 tablespoons of Biscoff spread directly to the brownie batter
- Make sure you’re using the correct amount of Biscoff spread in the swirl
Brownies Too Soft to Cut Cleanly
- Allow more cooling time (at least 2 hours or refrigerate for 30 minutes)
- Use a warm, clean knife, wiping between cuts
- Add 1 tablespoon of flour to the recipe for slightly more structure
Biscoff Layer Sank Into Brownie Batter
- Make sure the Biscoff layer is thick enough by adding more powdered sugar
- Check that your brownie batter isn’t too thin
- Layer more carefully, using a gentle touch
Variations to Try
Once you’ve mastered the basic recipe, explore these exciting variations:
White Chocolate Biscoff Brownies
Replace half the dark chocolate with high-quality white chocolate for a sweeter, creamier base that complements the Biscoff flavor beautifully.
Triple Biscoff Brownies
Add 3 tablespoons of Biscoff spread to the brownie batter itself, along with the swirl and topping, for the ultimate Biscoff experience.
Salted Caramel Biscoff Brownies
Drizzle homemade or store-bought salted caramel sauce between the brownie and Biscoff layers for an extra dimension of flavor.
Chocolate Chip Biscoff Brownies
Add 100g of chocolate chips to the brownie batter—milk, dark, or white all work wonderfully.

Frequently Asked Questions
After sharing this recipe with countless friends and family, here are the questions I’m most commonly asked:
Can I use milk chocolate instead of dark chocolate? Yes, you can! The brownies will be sweeter, so you might want to reduce the sugar by about 25g. The Biscoff flavor will still come through, but the chocolate flavor will be milder.
I can’t find Lotus Biscoff spread. What can I substitute? While nothing exactly replicates the unique Biscoff flavor, other cookie butters or speculoos spreads can work. In a pinch, you could use creamy peanut butter with 1 teaspoon of cinnamon and 1 tablespoon of brown sugar added.
Why did my brownies sink in the middle? This usually happens when brownies are underbaked or removed from the oven too quickly. The dramatic temperature change causes the center to collapse. Try baking 3-5 minutes longer next time.
Can I make these gluten-free? Yes! Replace the all-purpose flour with a high-quality gluten-free blend. Unfortunately, traditional Lotus Biscoff contains gluten, but you can use gluten-free speculoos cookies and cookie butter alternatives that are now available in many specialty stores.
How do I know when the brownies are done? The perfect brownies will have a set edge but still be slightly soft in the center. A toothpick inserted should come out with a few moist crumbs, not completely clean (which would indicate overbaking).
Can I double the recipe? Absolutely! Use a 9×13-inch (23×33 cm) baking pan and increase the baking time by about 5-8 minutes, checking frequently toward the end.
My Biscoff swirl disappeared into the brownie. What happened? If your brownie batter is very hot when you add the Biscoff layer, it can melt into the batter. Make sure to let the chocolate mixture cool for at least 5 minutes before proceeding with the recipe.
The History Behind Lotus Biscoff
The story of these brownies wouldn’t be complete without understanding the fascinating history of their star ingredient:
Lotus Biscoff cookies were first created in 1932 in the small Belgian town of Lembeke by baker Jan Boone Sr. The company, Lotus Bakeries, began making these spiced shortcrust biscuits with a recipe that has remained largely unchanged for nearly 90 years.
The name “Speculoos” comes from the Latin word “speculum,” meaning mirror, which refers to the traditional wooden molds that created mirror images on the cookies. The cookies gained international fame when they became the in-flight snack for Delta Airlines in the 1980s, introducing millions of travelers to their distinctive caramelized flavor.
The ingenious spreadable version wasn’t invented until 2007, when a Belgian woman named Els Scheppers created it for a television competition called “De Bedenkers” (The Inventors). Lotus Bakeries saw the potential and bought her idea, launching Biscoff spread commercially in 2009. It quickly developed a cult following that continues to grow globally.
By incorporating this beloved flavor into rich chocolate brownies, we’re continuing a tradition of culinary innovation that honors the original speculoos recipe while creating something new and exciting.
Final Thoughts
Creating these Lotus Biscoff Brownies has become something of a signature move when I want to really impress guests or bring something special to gatherings. The combination of rich chocolate with the warm, spiced caramel notes of Biscoff creates a dessert that’s both familiar and excitingly different.
What I love most about this recipe is how it transforms simple ingredients into something truly extraordinary. Yes, they take a bit more effort than basic brownies, but that extra care produces results that are absolutely worth it. The moment when someone takes their first bite and their eyes widen with pleasure—that’s what baking is all about.

Q&A Section
Are Lotus Biscoff Brownies suitable for vegetarians? Yes! The standard recipe contains no meat products. However, they do contain eggs and dairy, so they’re not suitable for vegans unless you make appropriate substitutions.
How can I make these brownies less sweet? You can reduce the sugar in the brownie base by up to 50g without affecting the texture significantly. Using darker chocolate (80-85% cocoa) will also reduce the overall sweetness while maintaining rich flavor.
Can I make these brownies ahead of time for a party? Absolutely! In fact, these brownies often taste even better the day after baking as the flavors have time to develop. You can make them up to 2 days in advance and store in an airtight container at room temperature.
What’s the secret to getting that perfect crackly top on brownies? The crackly top comes from properly dissolving the sugar in the melted chocolate and butter, and then adequately whisking the eggs to incorporate air. Don’t rush this process—proper whisking creates that beautiful shiny, crackly crust.
Can children help make this recipe? Definitely! Kids can help crush the cookies, mix ingredients, and create the swirls. Just supervise the chocolate melting step, as it involves heat.
Would these work as brownie bites in a mini muffin tin? Yes! For brownie bites, reduce the baking time to about 15-18 minutes and check frequently. This makes them perfect for parties or gifting.
If I want to mail these brownies to someone, what’s the best way to package them? Wrap each brownie individually in plastic wrap, then place in a rigid container with padding to prevent movement. They should be fine at room temperature for 3-4 days during shipping.
How can I tell if my Biscoff spread has gone bad? Biscoff spread typically has a long shelf life, but if it develops an off smell, changes in texture, or shows signs of mold, it should be discarded. Always check the expiration date on the jar.
