Introduction
These Biscoff Brownies combine the rich, fudgy texture of classic brownies with the unique caramelized flavor of Biscoff cookies and spread. With a crunchy cookie crust and swirled Biscoff topping, they’re a decadent treat perfect for any occasion.

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: Mix the crushed Biscoff cookies with 1/4 cup melted butter until combined. Press this mixture evenly into the bottom of the prepared pan using the back of a large spoon to form the crust.
- Step 3: In a large bowl, beat together the 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. Mix on medium speed until fully combined.
- Step 5: Sift together the flour, cocoa powder, and baking powder, then fold them gently into the wet ingredients using a rubber spatula until no streaks remain.
- Step 6: Pour the brownie batter over the prepared Biscoff cookie crust and spread it out evenly.
- Step 7: Warm the Biscoff spread in the microwave for 5-10 seconds until soft, then drop spoonfuls onto the brownie batter. Use a butter knife to swirl the spread into a pretty pattern.
- Step 8: Bake for 22-25 minutes, or until a toothpick inserted in the center comes out mostly clean. Note that baking times may vary, so check at around 23 minutes for the ideal texture.
- Step 9: Remove the brownies from the oven and let them cool completely in the pan before cutting and serving.
Tips & Variations
- For extra crunch, sprinkle chopped Biscoff cookies on top before baking.
- If you prefer a fudgier brownie, reduce the baking time slightly.
- Use vanilla bean paste instead of extract for a more intense vanilla flavor.
- Substitute salted butter with unsalted butter plus a pinch of salt if preferred.
Storage
Store cooled Biscoff Brownies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week or freeze for up to 3 months. To enjoy after refrigeration or freezing, allow the brownies to come to room temperature or warm briefly in the microwave.

FAQs
Can I use regular cookies instead of Biscoff cookies for the crust?
While Biscoff cookies have a unique flavor and texture that make these brownies special, you can substitute with graham crackers or digestive biscuits for a different but still tasty crust.
Is it necessary to use room temperature eggs?
Room temperature eggs whip better and help create a lighter, creamier batter, resulting in a better brownie texture. If your eggs are cold, you can warm them slightly by placing them in warm water for a few minutes.

Ingredients
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 (0.5g)
Topping
- 1/3 cup smooth Biscoff spread (80g)
Instructions
- Prepare Oven and Pan: Preheat your oven to 350°F (175°C) and line an 8 x 8-inch baking pan with parchment paper, ensuring the sides are covered for easy removal later.
- Make the Crust: In a bowl, combine the crushed Biscoff cookie crumbs with 1/4 cup of melted and cooled salted butter. Press this mixture evenly into the bottom of the prepared pan using the back of a large spoon to form a firm crust layer.
- Mix Eggs and Sugars: In a large mixing bowl, place the 2 large eggs, granulated sugar, and light brown sugar. Beat on high speed using a hand or stand mixer for 1 minute until the mixture lightens in color and becomes creamy and fluffy.
- Add Butter and Vanilla: Reduce mixer speed to medium and blend in the 1/2 cup melted and cooled butter along with the vanilla extract or vanilla bean paste until fully combined.
- Sift Dry Ingredients: Sift together the all-purpose flour, unsweetened baking cocoa, and baking powder to avoid lumps, then add the dry mixture to the wet ingredients.
- Combine Batter: Gently fold the dry ingredients into the wet mixture using a rubber spatula until just combined, being careful not to overmix to maintain fudgy brownies.
- Assemble Brownies: Pour the prepared batter over the Biscoff crust in the pan. Spread it evenly with a spatula, ensuring full coverage.
- Swirl Biscoff Spread: Warm the Biscoff spread in the microwave for 5 to 10 seconds until slightly melted and soft. Spoon the spread over the brownie batter and use a butter knife to swirl it artistically into the batter.
- Bake: Place the pan in the preheated oven and bake for 22-25 minutes, checking around 23 minutes for doneness by inserting a toothpick in the center. The toothpick should come out mostly clean with a few moist crumbs.
- Cool and Serve: Remove the brownies from the oven and allow them to cool completely in the pan before cutting into squares for serving.
Notes
- Make sure the melted butter is cooled before adding to eggs to avoid curdling.
- Oven temperatures vary; start checking your brownies at the earliest recommended baking time to prevent overbaking.
- Use parchment paper with overhang for easy removal of the brownies from the pan.
- For extra fudginess, slightly underbake the brownies and allow them to set as they cool.
- You can substitute salted butter with unsalted butter plus a pinch of salt if preferred.
