Ingredients

1 1/2 cups crushed Biscoff cookies (about 20 cookies, 155g)

1/4 cup salted butter, melted and cooled (56g)

2 large eggs, room temperature (112g)

1/2 cup granulated sugar (100g)

1/2 cup packed light brown sugar (100g)

1/2 cup salted butter, melted and cooled (113g)

2 tsp vanilla extract or vanilla bean paste (8g)

1/2 cup all-purpose flour (65g)

1/3 cup unsweetened baking cocoa (33g)

1/4 tsp baking powder (about 1g)

1/3 cup smooth Biscoff spread (80g)

Instructions

Step 1: Preheat the oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper. Set aside.

Step 2: In a bowl, combine the crushed Biscoff cookies with 1/4 cup melted butter. Press this mixture evenly into the bottom of the prepared pan using the back of a spoon to form the crust.

Step 3: In a large bowl, beat 2 large eggs, granulated sugar, and brown sugar on high speed for 1 minute until the mixture lightens in color and becomes creamy.

Step 4: Add the remaining 1/2 cup melted butter and vanilla extract to the egg mixture, mixing on medium speed until just combined.

Step 5: Sift together the flour, cocoa powder, and baking powder. Gently fold these dry ingredients into the wet mixture with a rubber spatula until just incorporated.

Step 6: Pour the brownie batter over the Biscoff cookie crust and spread evenly.

Step 7: Warm the Biscoff spread in the microwave for 5-10 seconds until soft. Spoon it over the brownie batter and use a butter knife to swirl it into a pretty pattern.

Step 8: Bake for 22-25 minutes, or until a toothpick inserted into the center comes out mostly clean. Cool completely before cutting into squares.

Tips & Variations

For extra fudgy brownies, slightly underbake by removing them a minute or two earlier than the suggested time.

Swap the Biscoff crust with graham cracker crumbs mixed with butter for a different texture.

Add chopped nuts or chocolate chips into the batter for added crunch and chocolate bursts.

Use natural peanut butter swirled in place of Biscoff spread for a peanut twist.

FAQs

Can I use regular peanut butter instead of Biscoff spread?

Yes, you can substitute smooth peanut butter to create a different but equally delicious swirl. It will change the flavor profile but keep the creamy texture of the topping.

How do I know when the brownies are done?

The brownies are ready when a toothpick inserted into the center comes out mostly clean with a few moist crumbs. This ensures a fudgy texture without being too gooey or underbaked.
