Step‑by‑Step Instructions for Biscoff Brownies (Gooey & Fudgy)
Step 1: Prep the Oven and Pan
Begin by preheating your oven to 350°F (180°C). While it heats up, take an 8-inch square baking pan and line it with parchment paper, allowing some overhang for easy removal later. This step sets the stage for perfectly baked Biscoff brownies, ensuring they don’t stick to the pan.
Step 2: Melt Butter and Chocolate
In a heatproof bowl, combine the unsalted butter and semi-sweet or dark chocolate, then melt them gently using a double boiler or your microwave. If using the microwave, heat in 30-second intervals, stirring in between until smooth and glossy. Allow the mixture to cool slightly before moving on to the next step, ensuring a balanced texture in your brownies.
Step 3: Whisk Eggs, Sugar, and Vanilla
In a large mixing bowl, whisk together the room-temperature eggs, granulated sugar, and pure vanilla extract until the mixture becomes pale and fluffy, approximately 2-3 minutes. This step is crucial for aerating the batter and achieving that rich, fudgy consistency that makes these Biscoff brownies so irresistible.
Step 4: Combine with Chocolate Mixture
Gently fold in the slightly cooled melted chocolate mixture into the egg and sugar blend, stirring until just combined. Be careful not to overmix the batter at this stage; the goal is to maintain the airy texture while blending flavors. This step allows the deep chocolate flavor to infuse beautifully throughout the brownies.
Step 5: Fold in Dry Ingredients
Next, sift together the all-purpose flour, unsweetened cocoa powder, and a pinch of salt. Carefully fold the dry ingredients into the wet mixture using a spatula until you see no dry streaks, ensuring the batter remains smooth and thick. Now the foundation of your gooey Biscoff brownies is almost complete.
Step 6: Add Crushed Biscoff Cookies
Once the batter is fully mixed, gently fold in the crushed Biscoff cookies. This adds delightful texture and bursts of flavor with every bite. Make sure the cookie pieces are evenly distributed throughout the brownie batter to maximize the deliciousness in your final product.
Step 7: Pour and Swirl Cookie Butter
Pour the luscious brownie batter into your prepared baking pan, spreading it evenly. Then, dollop spoonfuls of cookie butter on top, swirling it gently with a knife or toothpick to create beautiful swirls. Optionally, press additional crushed Biscoff cookies on top for extra crunch and visual appeal.
Step 8: Bake to Perfection
Place the pan in the preheated oven and bake for 30–35 minutes. You'll know your Biscoff brownies are ready when the tops are set but still slightly soft in the center; a toothpick should come out with a few moist crumbs. This ensures that gooey, fudgy texture you love!
Step 9: Cool and Chill
After baking, remove the brownies from the oven and allow them to cool completely in the pan on a wire rack. For best results, chill the brownies in the refrigerator for 1 hour to firm up, making them easier to cut into neat squares. This last step helps you achieve those perfect edges and keeps the scrumptious filling intact.

How to Store and Freeze Biscoff Brownies
Room Temperature: Store your Biscoff brownies in an airtight container at room temperature for up to 5 days. This keeps them fresh and maintains their gooey texture.
Fridge: For extended freshness, you can refrigerate the brownies in an airtight container, where they'll stay good for up to 7 days. Just remember to let them come back to room temperature before serving for the best taste!
Freezer: To freeze, wrap individual brownies tightly in plastic wrap and then place them in a freezer-safe bag. They can last for up to 3 months in the freezer, ensuring you have a delicious treat ready at any time.
Reheating: When you're ready to enjoy, simply thaw overnight in the refrigerator and reheat in the microwave for about 10-15 seconds, just until warm. This will revive their gooey, fudgy goodness!
