Step‑by‑Step Instructions for Fudgy Biscoff Brownies with Cookie Butter Swirl

Step 1: Preheat the Oven and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While the oven warms up, grab an 8×8-inch baking pan and line it with parchment paper, allowing some overhang for easy removal later. This will ensure that your fudgy Biscoff brownies come out intact and ready for slicing.

Step 2: Make the Biscoff Crust
In a mixing bowl, combine 1.5 cups of crushed Biscoff cookies with 1/4 cup of melted salted butter. Stir well until the mixture resembles wet sand. Press this mixture firmly into the bottom of the prepared pan, creating an even layer. This cookie crust will be the delicious foundation for your brownies, so take your time to ensure it’s compact.

Step 3: Whip Up the Batter
In a large bowl, use a whisk or electric mixer to beat together 2 eggs, 1/2 cup granulated sugar, and 1/4 cup light brown sugar. Mix until the mixture is creamy and lighter in color, which should take about 2-3 minutes. This step adds air to the batter, creating that desired fudgy texture in your Biscoff brownies.

Step 4: Add Wet Ingredients
Next, blend in 1/2 cup of melted salted butter and 1 teaspoon of vanilla extract to the egg mixture. Stir until well combined, making sure there are no lumps. The addition of butter and vanilla adds richness and depth to your brownie batter, making every bite unforgettable.

Step 5: Combine the Dry Ingredients
Now, sift in 1/2 cup of all-purpose flour, 1/4 cup of unsweetened cocoa powder, and 1/4 teaspoon of baking powder into the wet ingredients. Gently fold everything together using a spatula until just combined, being careful not to overmix. The batter might appear thick and fudgy, a hallmark of your soon-to-be Biscoff brownies.

Step 6: Layer the Brownie Batter
Pour the brownie batter over the Biscoff crust in the lined pan. Use a spatula to spread it evenly across the surface. The fudgy brownie layer should completely cover the crust, creating a harmonious blend of textures that will melt in your mouth once baked.

Step 7: Create the Biscoff Swirl
In a microwave-safe bowl, heat 1/4 cup of smooth Biscoff spread for about 5-10 seconds until it’s slightly softened. Spoon dollops of this warm Biscoff spread over the brownie batter. With a knife or skewer, swirl it gently into the batter, creating a marbled effect that not only looks beautiful but also adds bursts of Biscoff flavor.

Step 8: Bake to Perfection
Place the pan in the preheated oven and bake for 22-25 minutes. To check for doneness, insert a toothpick into the center; it should come out mostly clean, with a few moist crumbs attached. Take care not to overbake, as you want those fudgy Biscoff brownies to retain their luscious texture.

Step 9: Cool and Cut
Once baked, remove the pan from the oven and allow the brownies to cool completely in the pan. This step is crucial; letting them cool helps set the texture, making for cleaner cuts. Once cool, lift the parchment paper to extract the brownies, slice them into squares, and prepare to indulge in their delightful flavors!

Tips for the Best Biscoff Brownies

  • Pale and Puffed: Beat the eggs and sugars until pale and creamy to achieve a beautifully crackly top on your brownies.
  • Fine Crumbs: Ensure you crush the Biscoff cookies to a fine crumb for a uniform and delicious crust that supports the fudgy batter.
  • Room Temperature Ingredients: Using room temperature ingredients helps them blend together smoothly, keeping your Biscoff brownies moist and fudgy.
  • Chill for Clean Cuts: Allow the brownies to cool completely before slicing; for even cleaner cuts, use a hot knife dipped in water.
  • Double the Fun: If you’re doubling the recipe, opt for a larger 9×13-inch pan and adjust the baking time to about 25-30 minutes.
