Introduction

These Biscoff Brownies combine the rich, fudgy texture of classic brownies with the unique, crunchy sweetness of Biscoff cookies and spread. Perfect for anyone who loves caramelized cookie flavors wrapped in a decadent dessert.

A stack of three thick brownie squares with creamy peanut butter swirled inside each piece is placed on crumpled parchment paper atop a silver tart pan. Each brownie has two visible layers: a dense, dark chocolate base with a fudgy texture and a generous swirled layer of smooth, tan peanut butter running through the middle, creating a marbled pattern. The edges of the brownies are slightly crisp and cracked. The background shows a glass of milk softly blurred on a white marbled surface, adding a cozy and inviting feel to the image. photo taken with an iphone --ar 4:5 --v 7

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 (>1g)
1/3 cup smooth Biscoff spread (80g)

Instructions

Step 1: Preheat oven to 350°F (175°C) and line an 8 x 8-inch baking pan with parchment paper. Set aside.
Step 2: In a bowl, mix together 1 1/2 cups crushed Biscoff cookie crumbs with 1/4 cup melted butter. Press this mixture firmly into the bottom of the prepared pan using the back of a large spoon.
Step 3: In a large bowl, beat 2 large eggs, 1/2 cup granulated sugar, and 1/2 cup brown sugar on high speed for 1 minute until the mixture becomes lighter in color and creamy.
Step 4: Add 1/2 cup melted and cooled butter and 2 teaspoons vanilla extract to the egg mixture. Mix on medium speed until combined.
Step 5: Sift together 1/2 cup all-purpose flour, 1/3 cup cocoa powder, and 1/4 teaspoon baking powder, then add to the wet ingredients.
Step 6: Gently fold the dry ingredients into the wet mixture using a rubber spatula until just combined.
Step 7: Pour the brownie batter evenly over the Biscoff crust in the pan, spreading it smoothly.
Step 8: Warm 1/3 cup Biscoff spread in the microwave for 5-10 seconds until soft. Spoon dollops over the brownie batter and use a butter knife to swirl it, creating a marbled effect.
Step 9: Bake for 22-25 minutes, testing at 23 minutes for doneness by inserting a toothpick—it should come out mostly clean with a few moist crumbs.
Step 10: Remove from oven and allow brownies to cool completely in the pan before cutting into squares.

Tips & Variations

For extra texture, sprinkle chopped toasted nuts or chocolate chips on top before baking.
You can substitute regular vanilla extract with vanilla bean paste for a more intense flavor.
If you prefer a less sweet crust, reduce the amount of cookie crumbs or butter slightly.

Storage

Store cooled brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze for up to 3 months. When reheating, warm gently in a microwave or let come to room temperature for best texture.

How to Serve

A group of dark chocolate brownies cut into neat squares lie on a crinkled piece of light brown parchment paper on a white marbled surface. Each brownie has swirls of smooth peanut butter in golden brown color, mixed with scattered pieces of crunchy peanut cookie bits on the top, creating an interesting marbled texture. The brownies look thick, soft, and moist with a rich dark brown base and lightened by the creamy peanut butter swirls. Nearby, a white bowl filled with glossy peanut butter, a clear glass of milk, a white bowl with dark chocolate chunks, and a knife with a wooden handle lie casually on the white marbled surface. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use regular peanut butter instead of Biscoff spread?

While peanut butter will change the flavor profile, it can be used as a substitute. Expect a nuttier, less caramelized taste compared to the unique Biscoff flavor.

How do I know when the brownies are perfectly baked?

A toothpick inserted in the center should come out mostly clean with a few moist crumbs. Baking times may vary by oven, so start checking around 22 minutes to avoid overbaking and dry brownies.
