Biscoff Brownies Ingredients
For the Cookie Crust
• Crushed Biscoff Cookies – Provides the crust and a robust cookie flavor. Approx. 20 cookies (1.5 cups); substitute with graham crackers if needed.
• Salted Butter – Adds richness to the brownies and crust. Use unsalted butter if preferred, adjusting salt in the recipe.
For the Brownie Batter
• Large Eggs – Essential for structure and moisture. Make sure they are at room temperature for better incorporation.
• Granulated Sugar – Adds sweetness and contributes to texture. Can be replaced with coconut sugar for a deeper flavor.
• Light Brown Sugar – Enhances flavor and moisture. Substitute with dark brown sugar for a richer taste.
• Vanilla Extract/Vanilla Bean Paste – Adds warmth and depth of flavor. Substitutes can include almond extract or omit for a purer chocolate taste.
• All-Purpose Flour – Provides structure to the brownies. Gluten-free flour can be used as a substitute for a gluten-free version.
• Unsweetened Cocoa Powder – Gives chocolate taste and color. Dark cocoa powder can be swapped for a more intense chocolate flavor.
• Baking Powder – Helps the brownies rise slightly.
• Smooth Biscoff Spread – Adds flavor and luxurious texture. If unavailable, almond or peanut butter can be used as alternatives.
Step‑by‑Step Instructions for Biscoff Brownies
Step 1: Preheat and Prepare Pan
Begin by preheating your oven to 350°F (175°C). Prepare an 8×8-inch baking pan by lining it with parchment paper, allowing some overhang for easy removal later. This step ensures your Biscoff brownies will bake evenly and makes for a hassle-free cleanup.
Step 2: Make the Cookie Crust
In a mixing bowl, combine crushed Biscoff cookies with melted salted butter, stirring until the mixture resembles wet sand. Press this mixture firmly into the bottom of the prepared baking pan, creating an even layer that serves as the flavorful crust for your decadent Biscoff brownies.
Step 3: Whip Eggs and Sugars
In a separate bowl, whisk together large eggs, granulated sugar, and light brown sugar until the mixture is light, creamy, and doubles in volume—this should take about 1 minute. Whipping the eggs helps create that lovely, crackly brownie top, essential for a perfect Biscoff brownie experience.
Step 4: Mix in Wet Ingredients
Add the melted butter and vanilla extract to the egg mixture, stirring gently until everything is well combined. This addition enhances the flavor and richness of your brownie batter, further infusing it with that delightful Biscoff essence we all adore.
Step 5: Combine Dry Ingredients
Sift in the all-purpose flour, unsweetened cocoa powder, and baking powder to the wet mixture. Gently fold the ingredients together until just combined, being careful not to overmix. Overmixing can result in a tougher brownie, whereas this softness is key for fudgy Biscoff brownies.
Step 6: Pour Batter Over Crust
Carefully pour the brownie batter over your pressed cookie crust, using a spatula to spread it evenly across the surface. The rich, dark brownie layer will contrast beautifully with the crunchy cookie base, promising a delightful bite of Biscoff goodness in every piece.
Step 7: Swirl in Biscoff Spread
Heat the Biscoff spread in the microwave for 5-10 seconds until it becomes just warm and pliable. Dollop spoonfuls of the spread onto the brownie batter and use a knife to create gentle swirls. This step adds richness and creates a beautiful marbled effect on your Biscoff brownies.
Step 8: Bake the Brownies
Place the pan in the preheated oven and bake for 22-25 minutes. Check for doneness using a toothpick inserted into the center—the toothpick should come out mostly clean, indicating that your fudgy Biscoff brownies are ready to be devoured.
Step 9: Cool and Slice
Once baked, remove the brownies from the oven and allow them to cool completely in the pan. This cooling period helps them set up firmly and makes slicing easier. For clean edges, consider chilling them briefly in the fridge before cutting into generous squares of delight.

Biscoff Brownies Recipe FAQs
What type of Biscoff cookies should I use for the crust?
Absolutely! For the crust, use regular Biscoff cookies, as they provide the needed flavor and texture. You can crush about 20 cookies (approximately 1.5 cups) to achieve that rich, cookie-based crust. If you can’t find Biscoff cookies, a substitute like graham crackers works well too!
How should I store leftover Biscoff brownies?

What if my brownies turn out too dense or dry?
Very common! If your brownies are too dense, it might be due to overmixing the batter or not measuring your ingredients accurately. Make sure to fold the dry ingredients in slowly until just combined. A toothpick inserted should come out with a few moist crumbs—this indicates a perfect fudgy texture! If they turn out dry, perhaps they were baked a little too long; keep an eye on them in the last few minutes of baking.
Are there any dietary considerations to keep in mind with Biscoff brownies?
While there are no specific dietary restrictions mentioned for this recipe, it’s always good to think about allergies. Biscoff cookies contain wheat and may have traces of nuts, so be cautious if serving to anyone with gluten or nut allergies. You can also make these brownies gluten-free by using a gluten-free flour blend in place of all-purpose flour.
Can I customize my Biscoff brownies with other ingredients?
The more the merrier! Feel free to mix in chopped nuts, chocolate chips, or even a sprinkle of sea salt on top for a delicious variation.
