Biscoff Brownie Ingredients
For the Brownie Base
• Biscoff cookie spread – Provides a creamy, spiced flavor; substitute with other cookie or nut butters for varied taste.
• Unsalted butter – Adds richness and moisture; always use unsalted for better salt control.
• Chopped semi-sweet chocolate (70%) – Enhances the chocolate flavor and contributes to the fudginess; feel free to use milk chocolate for a sweeter treat.
• White granulated sugar – Sweetness and structure; brown sugar can be swapped for a deeper flavor.
• Large eggs (2) + Egg yolk (1) – Provides structure and leavening; omitting eggs changes texture significantly.
• Pure vanilla extract – Adds depth of flavor; opt for high-quality vanilla for the best results.
• Oil (canola or vegetable) – Adds moisture and tenderness; melted coconut oil is a suitable alternative.
• All-purpose flour – Provides structure; a gluten-free flour blend works as a substitute for those with dietary restrictions.
• Dutch process cocoa powder – Delivers a rich chocolate taste; natural cocoa powder can be used but will subtly alter the final result.
• Cornstarch – Contributes to a chewy texture; skipping this will slightly affect the texture.
• Salt – Enhances sweetness and flavor; essential for a well-balanced brownie.
For the Mix-ins
• Biscoff cookie pieces – Adds delightful texture and flavor; chop finely for better incorporation.
• Mini chocolate chips – Provides additional chocolatey bursts; dark chocolate chips deliver a richer flavor profile.
Step‑by‑Step Instructions for Biscoff Brownies
Step 1: Prepare Your Baking Pan
Start by preheating your oven to 325°F (163°C) and gather an 8×8-inch baking pan. Line the bottom and sides of the pan with parchment paper, allowing some overhang for easy removal later. This crucial step ensures your fudgy Biscoff brownies release smoothly after baking, giving you perfectly square edges to admire.
Step 2: Freeze the Biscoff Spread
To make handling easier, place the Biscoff cookie spread into the freezer for about 15-20 minutes. This firming up process will allow it to hold its shape better when you incorporate it into the brownie layer. Once frozen, remove it from the freezer and slice it into small rounds, making it easier to create that gooey center.
Step 3: Melt Chocolate and Butter
In a medium saucepan over low heat, melt the unsalted butter and chopped semi-sweet chocolate together, stirring frequently until smooth and glossy. This should take around 5-7 minutes. Once fully melted, remove the saucepan from heat and let the mixture cool slightly before adding it to the batter, ensuring it doesn’t cook the eggs later on.
Step 4: Whisk the Egg Mixture
In a large mixing bowl, combine the large eggs, egg yolk, and white granulated sugar. Using an electric mixer, whisk the mixture on high speed for about 5 minutes, or until it’s pale, thick, and fluffy. This aeration step is essential for achieving that tender, fudgy texture in your Biscoff brownies.
Step 5: Combine Wet Ingredients
Gently pour the slightly cooled chocolate-butter mixture into the whisked egg mixture, followed by the vegetable oil and pure vanilla extract. Using a spatula, carefully mix until everything is combined and there are no visible streaks. This will make your Biscoff brownies rich and flavorful.
Step 6: Fold in Dry Ingredients
In another bowl, whisk together the all-purpose flour, Dutch process cocoa powder, cornstarch, and salt. Gradually fold this dry mixture into the wet ingredients using a spatula, carefully mixing just until combined. Be mindful not to overmix, as it can affect the brownie’s texture, leading to less fudginess.
Step 7: Add Mix-ins
Gently fold in the chopped Biscoff cookie pieces and mini chocolate chips, ensuring even distribution throughout the batter. This not only enriches the flavor profile of your Biscoff brownies but also gives you delightful texture bursts in every bite.
Step 8: Assemble the Brownies
Pour half of the brownie batter into the prepared pan and spread it evenly. Next, take your frozen Biscoff rounds and layer them on top of the batter, creating a deliciously gooey center. Carefully spoon the remaining batter over the top, spreading it gently to fully cover the cookie spread.
Step 9: Decorate and Bake
For an extra touch, decorate the top of your brownies with a few Biscoff cookie pieces, pressing them lightly into the surface. Place the pan in the preheated oven and bake for 40-50 minutes. The center should look slightly underdone when you take them out, which ensures a fudgy texture after cooling.
Step 10: Cool and Serve
Allow your fudgy Biscoff brownies to cool completely in the pan on a wire rack. After about an hour, use the parchment overhang to lift them out. Cut the brownies into squares and serve warm for that delightful chocolate and cookie butter experience. Enjoy every blissful bite!

Make Ahead Options
These fudgy Biscoff brownies are perfect for busy home cooks looking to save time! You can prepare the brownie batter up to 24 hours in advance by mixing all the wet and dry ingredients separately and storing them in airtight containers in the refrigerator. The Biscoff cookie spread can also be frozen for up to 3 months. When you’re ready to bake, simply bring the ingredients to room temperature, fold in the mix-ins, and layer the cookie spread as usual. This way, your brownies come out just as delicious as if made from scratch on the spot, leaving you with more time to enjoy your day!
Expert Tips for Biscoff Brownies
