Biscoff Brownie Ingredients
For the Cookie Crust
• Crushed Biscoff Cookies – This forms the base, providing a delicious flavor and crunchy texture that elevates the brownies.
• Salted Butter (1/4 cup) – Adds richness to the crust; unsalted butter works too—just sprinkle in a bit of salt.
For the Brownie Batter
• Salted Butter (1/2 cup) – Keeps the brownies fudgy and decadent; switch to unsalted with a pinch of salt for a similar effect.
• Large Eggs (2) – Essential for moisture and structure; substitute with 2 flaxseed eggs for an egg-free version.
• Granulated Sugar (1/2 cup) – Sweetness is key to balance; coconut sugar offers a lower glycemic alternative.
• Light Brown Sugar (1/2 cup) – Infuses a subtle caramel flavor; for a richer taste, you can use dark brown sugar instead.
• Vanilla Extract (2 tsp) – Enhances the overall chocolate flavor profile; substitute with vanilla bean paste for an exquisite twist.
• All-Purpose Flour (1/2 cup) – Provides the necessary structure for your fudgy brownies; choose gluten-free flour for those avoiding gluten.
• Unsweetened Baking Cocoa (1/3 cup) – Introduces a deep chocolate flavor; opt for dark cocoa if you prefer a more intense taste.
• Baking Powder (1/4 tsp) – Aids in leavening, giving your brownies a perfect lift.
• Smooth Biscoff Spread (1/3 cup) – Add this luxurious layer to the batter for extra flavor; warm it slightly to swirl more easily.
These Biscoff Brownies offer a unique twist on a classic dessert, promising a rich, indulgent experience that everyone will love! Enjoy the sweet adventure ahead!
Step‑by‑Step Instructions for Biscoff Brownies
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Line an 8 x 8-inch baking pan with parchment paper, ensuring it hangs over the edges for easy removal later. This step sets the foundation for your Biscoff brownies, allowing them to bake evenly and helping with clean slicing after they’re baked.
Step 2: Create the Cookie Crust
In a mixing bowl, combine crushed Biscoff cookies with melted butter until fully incorporated. Press this mixture firmly into the bottom of your prepared pan to form a crust that’s compact and even. This will create a delicious base, offering a delightful crunch that pairs beautifully with the fudgy brownie batter.
Step 3: Whip the Eggs
In a separate large bowl, use a mixer to whip together the eggs on high speed for about 1 minute, which will lighten their texture. Gradually add in the granulated and brown sugars while continuing to mix until the mixture becomes creamy and well-combined, inviting sweet flavor into your Biscoff brownies.
Step 4: Mix in Butter and Vanilla
Reduce the mixer speed to medium, then pour in the melted butter and vanilla extract, mixing until everything is beautifully blended. This will enhance the richness of your brownie batter, ensuring that every bite of your Biscoff brownies is infused with velvety goodness and a touch of aromatic sweetness.
Step 5: Combine Dry Ingredients
Sift the all-purpose flour, unsweetened cocoa powder, and baking powder into your egg mixture. With a spatula, fold these dry ingredients gently until just combined. Be careful not to overmix, as this retains the fudgy texture that makes these Biscoff brownies so indulgent and tantalizing.
Step 6: Pour the Brownie Batter
Carefully pour the brownie batter over the Biscoff cookie crust in your baking pan, spreading it evenly with a spatula. This step is crucial for creating a smooth surface, ensuring that the brownies bake uniformly and provide that majestic layer of fudgy joy on top.
Step 7: Swirl in Biscoff Spread
Microwave the smooth Biscoff spread for 5-10 seconds to slightly warm it, making it easier to swirl. Drop spoonfuls of the spread over the brownie batter and use a knife to swirl it gently, creating beautiful marbled patterns that will enhance both flavor and presentation in your Biscoff brownies.
Step 8: Bake to Perfection
Place your baking pan in the preheated oven and bake for 22-25 minutes. To check for doneness, insert a toothpick into the center—aim for it to come out mostly clean but with a few moist crumbs still attached for that perfect fudgy texture that defines these Biscoff brownies.
Step 9: Cool and Slice
Once baked, remove the brownies from the oven and let them cool in the pan for a few minutes. For best results, transfer them to a wire rack to cool completely. This final cooling time is essential for achieving clean slices, enabling you to cut your Biscoff brownies into perfect squares for sharing (or indulging solo!).

Make Ahead Options
These fudgy Biscoff brownies are perfect for meal prep, making busy weeknights and unexpected guests a breeze! You can prepare the cookie crust up to 24 hours in advance; simply store it wrapped in plastic wrap at room temperature to maintain its crunch. Additionally, you can mix the brownie batter and refrigerate it for up to 3 days—just be sure to allow it to come to room temperature before pouring it over the crust. When you’re ready to enjoy your Biscoff brownies, swirl in the Biscoff spread and bake as directed for a sweet treat that’s just as delicious as when fresh!
Expert Tips for Biscoff Brownies
Room Temperature Ingredients: Ensure all ingredients are at room temperature for optimal mixing, resulting in a smoother batter and fudgier Biscoff brownies.
Metal Pan Preferred: Use a metal pan for the best results; if you’re using a glass dish, reduce the baking temperature to 325°F to avoid over-baking.
Cooling is Key: Allow your brownies to cool completely before cutting to achieve clean slices; a warm, sharp knife helps with this process, preventing a gooey mess.
Don’t Overmix: When combining dry and wet ingredients, mix just until combined to maintain the fudgy texture that makes these brownies irresistible.
Test for Doneness: Insert a toothpick into the center of the brownies; it should come out mostly clean, with a few moist crumbs for that perfect fudgy finish!
Creative Swirls: Experiment with different flavors of Biscoff spread or add chocolate chips to the brownie batter for extra indulgence in your Biscoff brownies!
Storage Tips for Biscoff Brownies
Room Temperature: Store the brownies in an airtight container at room temperature for up to 3 days to preserve their fudgy texture and flavor.
Fridge: If you prefer chilled brownies, keep them in the fridge in an airtight container for up to a week. Just note they may lose some of their gooeyness.
Freezer: For longer storage, freeze the brownies in a single layer, wrapped tightly in plastic wrap and placed in an airtight container for up to two months.
Thawing: When you’re ready to indulge again, thaw the Biscoff brownies overnight in the fridge before enjoying. They often taste even better after a brief rest!

Biscoff Brownies Recipe FAQs
How do I choose ripe ingredients for Biscoff brownies?
Absolutely! For the best results with Biscoff brownies, ensure your eggs are at room temperature to help them mix evenly into the batter. Your butter should also be softened or melted for easy incorporation. If using Biscoff cookies, select ones that are fresh and unbroken for the crust; avoid cookies with dark spots, which can indicate staleness.
What’s the best way to store Biscoff brownies?
Very! Store your Biscoff brownies in an airtight container at room temperature for up to 3 days. If you want them to last longer, place them in the fridge, where they can stay fresh for about a week, although this might alter their fudgy texture slightly. You can also freeze them for up to two months—just wrap each brownie individually in plastic wrap before placing them in an airtight container.
Can I freeze Biscoff brownies, and if so, how?
Absolutely! To freeze your Biscoff brownies, first, let them cool completely after baking. Once cooled, wrap each brownie tightly in plastic wrap, followed by aluminum foil to prevent freezer burn. Place the wrapped brownies in an airtight container or a resealable freezer bag. When you’re ready to enjoy them, thaw the brownies in the fridge overnight for the best taste and texture!
What should I do if my Biscoff brownies come out dry?
Oh, dear! If your Biscoff brownies turn out dry, it could be due to overbaking. To ensure they are fudgy, always check for doneness around the 22-minute mark, as ovens can vary. Remember, it’s okay if a toothpick comes out with a few moist crumbs attached — this guarantees that perfect fudgy texture! If you find your brownies are still dry, next time try reducing the baking time by a couple of minutes.
Are there any dietary considerations for Biscoff brownies?
Very! The Biscoff brownies contain gluten (from the flour) and dairy (from the butter). If you have a gluten intolerance, you can substitute all-purpose flour with a gluten-free blend. To make them dairy-free, use a plant-based butter alternative and coconut cream instead of Biscoff spread. Always check labels and ensure your substitutions meet your dietary needs.
Can pets eat Biscoff brownies?
Absolutely not! While Biscoff cookies themselves are not toxic to pets, Biscoff brownies contain sugar and butter, making them unhealthy for dogs and cats alike. It’s best to keep these delectable treats to yourself and not share them with your furry friends. Always provide pet-safe snacks instead!
