Biscoff Brownies Recipe
Introduction
These Biscoff Brownies combine the rich, fudgy texture of classic brownies with the irresistible flavor of Biscoff cookies and spread. Featuring a crunchy cookie crust and swirls of smooth Biscoff spread, this treat is perfect for any sweet tooth craving something a little different.

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 your 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 the crushed Biscoff cookies with 1/4 cup melted butter until combined. Press this mixture firmly into the bottom of the prepared pan, smoothing it evenly with the back of a large spoon.
- Step 3: In a large mixing bowl, beat the eggs, granulated sugar, and brown sugar together on high speed for 1 minute using a hand or stand mixer. The mixture should lighten in color and become creamy.
- Step 4: Add the 1/2 cup melted butter and vanilla extract to the egg mixture, mixing on medium speed until fully combined.
- Step 5: Sift the 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 in the pan and spread it evenly.
- Step 8: Warm the Biscoff spread in the microwave for 5 to 10 seconds until it’s soft but not liquid. Spoon dollops of the softened spread atop the batter, then swirl with a butter knife to create a marbled pattern.
- Step 9: Bake for 22 to 25 minutes, or until a toothpick inserted near the center comes out mostly clean. The ideal baking time may vary slightly by oven; 23 minutes often works well.
- Step 10: Remove from the oven and allow the brownies to cool completely in the pan before cutting into squares and serving.
Tips & Variations
- For extra texture, fold in chopped nuts like walnuts or pecans into the batter before baking.
- You can substitute regular butter with vegan butter for a dairy-free version.
- Use crunchy Biscoff spread to add a bit of crunch within the swirls.
- Make sure eggs are at room temperature to help achieve a smooth, creamy batter.
- Press the Biscoff crust firmly into the pan to prevent it from crumbling when cutting.
Storage
Store baked and 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 individual pieces for up to 2 months. To reheat, warm in the microwave for 10-15 seconds to bring back their soft, fudgy texture.

FAQs
Can I use a different type of cookie for the crust?
Yes, you can substitute Biscoff cookies with graham crackers, speculoos, or even digestive biscuits for a different flavor profile, though it will change the overall taste slightly.
What if I don’t have a mixer?
While a mixer makes it easier to get a creamy batter, you can whisk the eggs and sugars vigorously by hand until light and fluffy, but it may take a bit more effort.

- 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)

- 1/3 cup unsweetened baking cocoa (33g)
- 1/4 tsp baking powder (about 1g)
Topping
- 1/3 cup smooth Biscoff 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 to prevent sticking and make removal easier. Set aside.
- Make and Press Crust: In a bowl, combine the crushed Biscoff cookies with 1/4 cup melted butter until well mixed. Press this mixture firmly and evenly into the bottom of the prepared pan using the back of a spoon to form the crust layer.
- Mix Eggs and Sugars: In a large mixing bowl, add 2 large room temperature eggs, 1/2 cup granulated sugar, and 1/2 cup packed light brown sugar. Using a hand or stand mixer, beat on high speed for one minute until the mixture lightens in color and becomes creamy.
- Add Butter and Vanilla: Reduce mixer speed to medium and incorporate 1/2 cup melted and cooled butter along with 2 teaspoons of vanilla extract or vanilla bean paste. Mix until combined.
- Sift Dry Ingredients: Sift together 1/2 cup all-purpose flour, 1/3 cup unsweetened baking cocoa, and 1/4 teaspoon baking powder to remove lumps and aerate. Gradually add these dry ingredients to the wet mixture.
- Combine Batter: Carefully fold the sifted dry ingredients into the wet ingredients with a rubber spatula until just combined, avoiding overmixing to ensure a tender brownie texture.
- Assemble Brownie Layer: Pour the prepared brownie batter evenly over the pressed Biscoff crust layer in the pan, spreading it smoothly with a spatula.
- Add Biscoff Swirl: Warm 1/3 cup smooth Biscoff spread in the microwave for 5 to 10 seconds until softened. Spoon dollops evenly onto the brownie batter and use a butter knife to swirl the spread into a decorative pattern.
- Bake: Place the pan in the oven and bake for 22 to 25 minutes, or until a toothpick inserted near the center comes out mostly clean but still moist with a few crumbs. Around 23 minutes is ideal for a fudgy center.
- Cool and Serve: Remove the brownies from the oven and allow them to cool completely in the pan on a wire rack. Once cooled, cut into squares and serve.
Notes
- For best results, use room temperature eggs to ensure even mixing.
- Do not overbake the brownies; they should be moist in the center for optimal fudginess.
- The Biscoff swirl can be adjusted in quantity to taste; it adds a unique flavor and visual appeal.
- Allow brownies to cool fully before cutting to maintain clean edges.
- You can store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
