Step‑by‑Step Instructions for Biscoff Cookie Butter Brownies
Step 1: Prepare Your Pan and Cookie Butter
Start by lining an 8×8-inch baking pan with parchment paper, allowing some overhang for easy removal later. Next, place 200g of Biscoff cookie butter in the freezer to firm up while you move on to the oven.
Step 2: Preheat the Oven
Preheat your oven to 180°C (350°F), creating a warm environment for baking those Fudgy Biscoff Cookie Butter Brownies. This step is crucial for perfect baking, so make sure to give your oven enough time to reach the desired temperature.
Step 3: Mix the Sugars and Eggs
In a mixing bowl, whisk together brown sugar, granulated sugar, eggs, egg yolk, and vanilla extract until the mixture is smooth and well-combined. This should take about 2-3 minutes and will create a creamy base for your brownie batter.
Step 4: Melt Butter and Chocolate
In a saucepan, melt unsalted butter and semi-sweet chocolate chips over low heat. Stir continuously until the mixture becomes smooth and silky, then remove it from the heat and whisk in the Dutch cocoa powder for an intense chocolate flavor.
Step 5: Combine Dry and Wet Ingredients
Gently fold the melted chocolate mixture into the egg and sugar mixture, stirring until just combined. Be careful not to overmix; you want a rich, fudgy texture for your Biscoff Cookie Butter Brownies, so leave a few streaks of dry ingredients.
Step 6: Fold in the Dry Ingredients
Add in the all-purpose flour, espresso powder, and sea salt, folding them into the batter until no dry streaks remain. This should take about 30 seconds; the batter should look thick and luscious—perfect for those fudgy brownie dreams.
Step 7: Layer the Batter
Spread half of the brownie batter into the bottom of the prepared pan, creating an even layer. Once done, take your frozen Biscoff cookie butter and carefully place it on top, then spoon the remaining brownie batter over to cover completely.
Step 8: Add Crunchy Topping
Crumble the Biscoff cookies over the top of your brownie batter, pressing them in gently for added texture. Drizzle additional melted Biscoff cookie butter on top for an irresistible finishing touch, enhancing both the flavor and appearance.
Step 9: Bake the Brownies
Place the pan in your preheated oven and bake for 30-40 minutes. To check for doneness, insert a toothpick; it should come out with a few moist crumbs clinging to it, signaling the fudgy interior of your Biscoff Cookie Butter Brownies.
Step 10: Cool and Serve
Allow the brownies to cool completely in the pan on a wire rack. Once cooled, use the parchment overhang to lift them out, making it easy to slice into squares. These brownies are now ready to be enjoyed with friends or stored for later cravings!

Make Ahead Options
These Fudgy Biscoff Cookie Butter Brownies are a dream for meal prep enthusiasts! You can prepare the brownie batter up to 24 hours in advance by mixing the wet and dry ingredients separately; store them in the refrigerator to maintain freshness. Additionally, the Biscoff cookie butter can be frozen for up to 3 days to ensure it stays at the right consistency. When you’re ready to bake, simply combine the batters, layer the cookie butter, and bake as directed. This method not only saves time but ensures your brownies are just as delicious when served, helping you to enjoy homemade treats even on the busiest of nights!

Biscoff Cookie Butter Brownies Recipe FAQs
What type of Biscoff cookie butter should I use?
I recommend using the classic smooth Biscoff cookie butter, which provides that unique caramel flavor and creamy texture. If you’re looking for a nut-free alternative, almond or peanut butters can work, but keep in mind that these will change the flavor profile slightly.
How should I store the brownies?
Store your Biscoff Cookie Butter Brownies in an airtight container at room temperature for up to 2-3 days. For longer shelf life, you can refrigerate them for about a week, but be aware that they may firm up a bit. Just make sure they’re kept tightly wrapped.
Can I freeze the brownies? What’s the best way to do it?
Absolutely! To freeze your brownies, allow them to cool completely, then wrap each square tightly in plastic wrap. Place them in a zip-top freezer bag, and they can last for up to 3 months. When you’re ready to enjoy, simply thaw them at room temperature for a few hours or microwave them for a few seconds until warm.
What if my brownies are too dry or crumbly?
If your brownies turn out dry, it might be due to overbaking or using too much flour. For fudginess, aim for a toothpick that comes out with moist crumbs rather than clean. If this happens again, try reducing the baking time by a few minutes and ensure accurate measurements.
Are these brownies safe for pets?
No, unfortunately, these brownies aren’t safe for pets due to the chocolate and sugar content. Always keep desserts like these out of reach from your furry friends, as chocolate can be toxic to dogs and cats.
Can I make these brownies gluten-free?
Yes! To make gluten-free Biscoff Cookie Butter Brownies, simply substitute the all-purpose flour with a gluten-free flour blend. Be sure to check if your baking powder is also gluten-free. This results in a similar fudgy texture while accommodating gluten sensitivities.
