Biscoff Brownie Ingredients
For the Brownie Batter
• Butter (115 g / 1 stick) – Adds moisture and richness; you can substitute with plant-based butter for a dairy-free version.
• Semi-sweet or Dark Chocolate (200 g / 7 oz) – Provides depth of flavor; avoid using milk chocolate as it may be too sweet.
• Granulated Sugar (250 g / 1 ¼ cups) – Sweetens the brownies; brown sugar can add a richer taste.
• Eggs (4 large) – Binds the ingredients and adds moisture; for a vegan option, consider using flax eggs.
• All-purpose Flour (90 g / ¾ cup) – Gives structure to the brownies; use a gluten-free flour blend for a gluten-free version.
• Cocoa Powder (30 g / ¼ cup) – Enhances chocolate flavor; make sure it’s unsweetened to maintain balance.
• Salt (½ tsp) – Balances sweetness; an essential ingredient for flavor enhancement.
For the Biscoff Flavor
• Crushed Biscoff Cookies (approx. 10 cookies) – Adds texture and enhances the overall Biscoff flavor; can be replaced with additional cookie butter.
• Cookie Butter (90 g / ¾ cup) – Introduces a creamy swirl and enriched flavor; can replace with more crushed Biscoff cookies.
With these ingredients at hand, you’re just a few steps away from creating fudgy, gooey Biscoff brownies that will have everyone coming back for more!
Step‑by‑Step Instructions for Gooey Biscoff Brownies
Step 1: Melt Chocolate & Butter
Begin by combining 115 g of butter and 200 g of semi-sweet or dark chocolate in a heatproof bowl. Place it over a pot of simmering water to create a double boiler or microwave in short bursts until melted. Stir until the mixture is smooth and shiny, then let it cool slightly before moving on to the next step.
Step 2: Whisk Eggs and Sugar
In a separate large mixing bowl, whisk together 4 large eggs, 250 g of granulated sugar, and a splash of vanilla extract until the mixture is pale and fluffy, about 2-3 minutes. You want it to become aerated and frothy, which will help create a nice texture in your Biscoff brownies.
Step 3: Combine Mixtures
Pour the slightly cooled chocolate and butter mixture into the egg mixture. Stir gently until everything is well combined, ensuring there are no chocolate streaks left behind. The consistency should be thick and glossy, setting the stage perfectly for the fudgy goodness of the brownies.
Step 4: Fold in Dry Ingredients
Next, sift in 90 g of all-purpose flour, 30 g of cocoa powder, and ½ teaspoon of salt into the combined mixture. Use a spatula to gently fold these dry ingredients into the batter until just combined. Be careful not to over-mix, as this can make your brownies denser.
Step 5: Add Cookies
Now, take approximately 10 crushed Biscoff cookies and fold them gradually into the brownie batter. This introduces delightful texture and Biscoff flavor to your gooey brownies. Ensure that the cookie pieces are evenly distributed throughout the batter for a consistent bite.
Step 6: Prepare Baking Pan
Line an 8-inch square baking pan with parchment paper for easy removal later. Pour the thick batter into the prepared pan, using a spatula to smooth the top evenly. This will create a lovely even surface for your brownies to bake on, ensuring they cook thoroughly.
Step 7: Swirl & Top
Spoon about 90 g of cookie butter on top of the brownie batter in dollops, then take a knife and gently swirl it into the batter. Optional: Press additional crushed Biscoff cookies into the surface to enhance the texture. This step creates enticing swirls of cookie butter in your Biscoff brownies.
Step 8: Bake
Preheat your oven to 350°F (180°C) and place the pan in the oven. Bake for 30-35 minutes, checking for doneness towards the end. The edges should look set, while the center remains soft and slightly underbaked—perfect for that gooey brownie texture.
Step 9: Cool & Serve
Once baked, remove the brownies from the oven and let them cool completely in the pan on a wire rack. For best results, chill in the fridge for 1 hour before slicing into squares. This cooling time helps improve the texture and allows the flavors to meld beautifully in your Biscoff brownies.

Expert Tips for Biscoff Brownies
Avoid Overbaking: Check your brownies a few minutes before the recommended time; the edges should be set while the center remains slightly gooey for that perfect Biscoff brownie texture.
Cool Completely: Letting your brownies cool completely in the pan helps maintain a moist interior, preventing them from drying out. Be patient—it’s worth the wait!
Resist the Urge to Cut Early: Chilling the brownies for at least an hour after baking will make slicing much easier and yield cleaner edges.
Storage Savvy: Keep any leftovers in an airtight container at room temperature for up to a week, or freeze for future indulgence.

Biscoff Brownies Recipe FAQs
How do I choose the right chocolate for Biscoff brownies?
Absolutely! For the best flavor, I recommend using semi-sweet or dark chocolate. Milk chocolate can make the brownies overly sweet, while dark chocolate enhances the overall depth of flavor. Ensure you pick high-quality chocolate—after all, it’s a key player in this delicious dessert!
How should I store leftovers of my Biscoff brownies?
Keep the brownies in an airtight container at room temperature for up to 1 week. This helps maintain their fudgy goodness. If you’d like to store them longer, you can place them in the fridge for up to 2 weeks, allowing them to come to room temperature before serving for the best taste.
Can I freeze Biscoff brownies, and if so, how?
Very much! To freeze your Biscoff brownies, individually wrap them in plastic wrap and place them in an airtight container or a zip-top freezer bag. They can last in the freezer for up to 3 months. When you’re ready to enjoy them, simply thaw in the fridge overnight, and then microwave in 10-second intervals for a warm and gooey treat!
What should I do if my brownies are too gooey in the center?
If you find your brownies too gooey in the center, it likely means they weren’t baked long enough. Always check for doneness a few minutes before the time ends; the edges should be set, and the center slightly underbaked for that classic gooey texture. If necessary, you can pop them back in the oven for an additional 3-5 minutes, but keep a close watch to avoid overbaking.
Are these brownies suitable for those with allergies?
While these Biscoff brownies are a delightful treat, they contain eggs and butter, which are common allergens. If you need a dairy-free version, substitute with plant-based butter and consider using flax eggs instead of regular eggs. However, always check the ingredient labels on the cookie butter and Biscoff cookies, as they may contain allergens like nuts or gluten.
How can I enhance the flavor of my Biscoff brownies?
Get creative! You can substitute crushed Biscoff cookies for additional cookie butter for an even richer flavor. Adding a handful of chopped nuts, like walnuts or pecans, or even extra chocolate chunks can create delightful textures and enhance the decadent taste of your brownies!
