Introduction

Biscoff Brownies combine the rich, fudgy texture of classic brownies with the unique caramelized flavor of Biscoff cookies and spread. This easy-to-make treat has a crunchy cookie crust and a swirled Biscoff topping that makes every bite irresistible.

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 (less than 1g)
1/3 cup smooth Biscoff spread (80g)

Instructions

Step 1: Preheat the oven to 350°F (175°C) and line an 8 x 8-inch baking pan with parchment paper. Set aside.
Step 2: Mix the crushed Biscoff cookie crumbs with 1/4 cup melted butter. Press this mixture firmly into the bottom of the prepared pan to form the crust. Smooth the surface with the back of a spoon.
Step 3: In a large bowl, beat together the eggs, granulated sugar, and brown sugar on high speed for 1 minute until lighter in color and creamy.
Step 4: Add the 1/2 cup melted butter and vanilla extract to the egg mixture. Mix on medium speed until fully combined.
Step 5: Sift the all-purpose flour, cocoa powder, and baking powder into 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 over the Biscoff crust and spread it evenly.
Step 8: 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 the spread for a decorative pattern.
Step 9: Bake for 22 to 25 minutes, or until a toothpick inserted comes out mostly clean. Check at 23 minutes for best results as ovens vary.
Step 10: Remove from oven and allow the brownies to cool completely before cutting into squares.

Tips & Variations

For extra fudgy brownies, slightly underbake by a minute or two but avoid a very wet center.
Try adding chopped nuts or white chocolate chips to the batter for added texture and flavor.
If you prefer a stronger Biscoff flavor, swirl additional cookie spread on top before serving.
Use parchment paper with some overhang to easily lift brownies out of the pan for clean slicing.

Storage

Store 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. To reheat, warm briefly in the microwave until soft but not hot.

FAQs

Can I use regular cookies instead of Biscoff cookies?

While Biscoff cookies provide a unique caramelized flavor, you can substitute with other spiced or graham cookies. The taste will differ but the texture will still be enjoyable.

Do I need to use melted butter or can I use softened butter?

Melting the butter helps evenly incorporate it into the crust and batter, ensuring the right texture. Softened butter won’t mix as smoothly, so melted is best for this recipe.

Ingredients

Scale

Crust

1 1/2 cups crushed Biscoff cookies (about 20 cookies, 155g)
1/4 cup salted butter, melted and cooled (56g)

Brownie Batter

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 (approx. 1g)

Topping

1/3 cup smooth Biscoff cookie butter spread (80g)

Instructions

Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C) and line an 8 x 8-inch baking pan with parchment paper. This ensures the brownies won’t stick and will be easy to remove after baking.
Make Biscoff Cookie Crust: Combine the crushed Biscoff cookies with 1/4 cup melted butter. Press this mixture firmly and evenly into the bottom of the prepared pan using the back of a large spoon to form the crust layer.
Cream Eggs and Sugars: In a large mixing bowl, place the 2 large eggs, granulated sugar, and brown sugar. Using a hand or stand mixer on high speed, beat for 1 minute until the mixture lightens in color and becomes creamy and fluffy, creating a smooth base for the brownie batter.
Add Butter and Vanilla: On medium speed, mix in the remaining 1/2 cup melted and cooled butter along with 2 teaspoons of vanilla extract or vanilla bean paste until fully combined and smooth.
Sift Dry Ingredients: Sift together the all-purpose flour, unsweetened cocoa powder, and baking powder to prevent lumps and ensure even distribution of leavening agents.
Fold Dry into Wet: Gently fold the sifted dry ingredients into the wet mixture using a rubber spatula. Mix carefully until just combined to maintain the lightness of the batter.
Assemble Brownies: Pour the prepared brownie batter over the pressed Biscoff cookie crust in the pan. Use a spatula to spread the batter into an even layer, covering the crust completely.
Add Biscoff Swirl: Warm the Biscoff cookie butter spread in the microwave for 5–10 seconds until soft. Spoon it dollop by dollop on top of the brownie batter, then swirl it through the batter with a butter knife to create a marbled pattern.
Bake: Place the brownie pan in the preheated oven. Bake for 22-25 minutes, testing doneness with a toothpick inserted in the center — it should come out mostly clean with a few moist crumbs. The ideal baking time is around 23 minutes, but watch closely as ovens vary.
Cool and Serve: Remove the brownies from the oven and allow them to cool completely in the pan. This cooling step is crucial for the brownies to set properly before cutting into squares and serving.

Notes

Use room temperature eggs for better mixing and batter texture.
Ensure melted butter is cooled before adding to avoid cooking the eggs.
For the Biscoff swirl, gently warm the cookie butter to make it easier to spread and swirl.
Baking times vary by oven; start checking at 22 minutes to avoid overbaking.
Line the pan with parchment for easy removal and cleaner cuts.
Store brownies in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
