Biscoff Brownies Ingredients
• Dive into the delicious world of Biscoff brownies with these simple ingredients!
For the Crust
- Crushed Biscoff Cookies – Adds crunch and structure; use about 20 cookies, crushed to ultra-fine crumbs for even pressing.
- Salted Butter (1/4 cup, melted) – Provides richness and moisture; ensure melted and cooled for the best results.
For the Brownie Batter
- Large Eggs (2, room temperature) – Essential for structure and aeration, contributing to a light texture.
- Granulated Sugar (1/2 cup) – Sweetness and a chewy texture; balances the richness of the cookie butter.
- Light Brown Sugar (1/2 cup, packed) – Adds sweetness and moisture, enhancing the flavor profile.
- Salted Butter (1/2 cup, melted) – Offers a fudgy consistency; melted to ensure a rich brownie batter.
- Vanilla Extract (2 tsp) – Provides aromatic sweetness; can substitute with vanilla bean paste for a deeper flavor.
- All-Purpose Flour (1/2 cup) – Gives structure to the brownies; crucial for that perfect fudgy texture.
- Unsweetened Baking Cocoa (1/3 cup) – Deep chocolate flavor; consider using black cocoa for a richer taste.
- Baking Powder (1/4 tsp) – Helps the brownies rise slightly for that lovely, crackled top.
- Smooth Biscoff Spread (1/3 cup) – Adds a creamy, delicious swirl; heating slightly helps with a perfect swirl into the batter.
Step‑by‑Step Instructions for Fudgy Biscoff Brownies with Cookie Butter Swirl
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This crucial step ensures your fudgy Biscoff brownies bake evenly. While the oven is warming up, line an 8×8-inch baking pan with parchment paper, allowing enough overhang to facilitate easy removal later. Set the pan aside to prepare the crust.
Step 2: Make the Crust
In a medium bowl, combine the crushed Biscoff cookies with 1/4 cup of melted salted butter. Mix until the crumbs are fully coated and the mixture resembles wet sand. Press this crust mixture evenly into the bottom of the prepared pan, using the back of a measuring cup or your fingers to create a compact layer. Set this aside while you make the brownie batter.
Step 3: Whip the Eggs and Sugars
In a large mixing bowl, whip together 2 large eggs, 1/2 cup granulated sugar, and 1/2 cup packed light brown sugar. Using a hand mixer or whisk, blend until the mixture is creamy and lightened in color—aim for about 2-3 minutes. This step adds air to the brownies, contributing to their delicious texture.
Step 4: Combine the Wet Ingredients
Next, mix in 1/2 cup of melted salted butter and 2 teaspoons of vanilla extract to your egg-sugar mixture, stirring until well combined. This combination will contribute to the rich flavor of your fudgy Biscoff brownies.
Step 5: Incorporate the Dry Ingredients
Sift in 1/2 cup of all-purpose flour, 1/3 cup of unsweetened baking cocoa, and 1/4 teaspoon of baking powder directly into your wet mixture. Gently fold the dry ingredients into the batter using a spatula until just combined, being careful not to overmix, as this ensures a fudgy texture.
Step 6: Layer the Batter and Swirl the Spread
Pour the brownie batter over the prepared Biscoff cookie crust, spreading it evenly with a spatula. To add a delicious swirl, warm 1/3 cup of smooth Biscoff spread in the microwave for about 15 seconds until slightly softened. Using a knife, gently swirl the Biscoff spread into the brownie batter, creating a beautiful pattern on top.
Step 7: Bake the Brownies
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. Avoid overbaking to maintain that fudgy texture everyone loves in Biscoff brownies.
Step 8: Cool and Slice
Once baked, remove the brownies from the oven and let them cool completely in the pan at room temperature. This cooling step allows the flavors to meld and makes cutting easier. Once cooled, lift the brownies out of the pan using the parchment paper overhang and cut into squares for serving.
