Introduction
These fudgy Biscoff brownies are a delicious twist on a classic favorite, combining rich chocolate with the unique caramelized flavor of Biscoff cookies and spread. Perfectly chewy and packed with cookie bits, they make a treat that’s hard to resist.

Ingredients
- 250 g (8.8 oz / 1 ½ cups) baking chocolate or semi-sweet chocolate chips
- 115 g (1 stick) unsalted butter
- 4 large eggs, at room temperature
- 200 g (1 cup) granulated sugar
- 1 ½ tsp pure vanilla extract
- 90 g (¾ cup) all-purpose or cake flour
- 30 g (¼ cup) unsweetened cocoa powder (Dutch-processed preferred)
- ½ tsp salt
- 10 crushed Lotus Biscoff cookies (plus 4 extra for topping)
- 12 tsp Biscoff cookie butter spread
Instructions
- Step 1: Preheat the oven to 350°F (180°C) and line an 8-inch (20 cm) square baking pan with parchment paper.
- Step 2: Melt the butter and chocolate together in a heatproof bowl over a double boiler or in short microwave bursts until smooth.
- Step 3: Whisk the eggs, sugar, and vanilla extract for 2 minutes until pale and slightly foamy.
- Step 4: Combine the egg mixture with the melted chocolate and butter, mixing until smooth.
- Step 5: Fold in the flour, cocoa powder, and salt using a spatula—be careful not to overmix.
- Step 6: Add the crushed Biscoff cookies and mix just until combined.
- Step 7: Pour the batter into the prepared pan, smooth the top, then add dollops of Biscoff spread. Swirl lightly with a knife and sprinkle the extra cookie pieces on top.
- Step 8: Bake for 30–35 minutes, until the top is set and a toothpick inserted near the center comes out with moist crumbs.
- Step 9: Let the brownies cool completely in the pan, then refrigerate for 1 hour before slicing into 16 pieces.
Tips & Variations
- Use Dutch-processed cocoa powder for a deeper chocolate flavor and richer color.
- For extra gooey brownies, try adding small chunks of Biscoff spread inside the batter before baking.
- You can swap out the Biscoff cookies for speculoos or ginger snap cookies for a different spice note.
- Room temperature eggs help create a smoother batter and better texture.
Storage
Store brownies in an airtight container in the refrigerator for up to 5 days. Bring to room temperature or warm slightly before serving for the best texture. You can also freeze the brownies for up to 2 months; thaw in the fridge overnight.

FAQs
Can I use milk chocolate instead of semi-sweet chocolate?
Yes, milk chocolate will work but will result in a sweeter and less intense chocolate flavor. Adjust sugar accordingly if desired.
Why should I refrigerate the brownies before slicing?
Refrigerating helps the brownies set and makes slicing cleaner, especially with the Biscoff spread swirls and cookie pieces inside.

- 250 g (8.8 oz / 1 ½ cups) baking chocolate or semi-sweet chocolate chips
- 115 g (1 stick) unsalted butter
- 4 large eggs, at room temperature
- 200 g (1 cup) granulated sugar

Dry Ingredients

- 30 g (¼ cup) unsweetened cocoa powder (Dutch-processed preferred)
- ½ tsp salt
Biscoff Ingredients
- 10 crushed Lotus Biscoff cookies (plus 4 extra for topping)
- 12 tsp Biscoff cookie butter spread
Instructions
- Preheat and prepare the pan: Preheat your oven to 350°F (180°C) and line an 8-inch (20 cm) square baking pan with parchment paper to ensure easy removal of the brownies.
- Melt chocolate and butter: In a heatproof bowl set over a double boiler or using short bursts in the microwave, melt together the butter and baking chocolate until the mixture is smooth and well combined. Set aside.
- Whisk eggs, sugar, and vanilla: In a separate mixing bowl, whisk the eggs, granulated sugar, and vanilla extract together for about 2 minutes until the mixture is pale and slightly foamy, helping to incorporate air for a better texture.
- Combine wet mixtures: Pour the melted chocolate and butter mixture into the whisked eggs and sugar. Mix gently until the batter is smooth and uniform.
- Add dry ingredients: Using a spatula, fold in the all-purpose flour, cocoa powder, and salt carefully to avoid overmixing, which can make the brownies tough.
- incorporate Biscoff cookies: Gently fold the crushed Lotus Biscoff cookies into the batter until evenly distributed.
- Prepare to bake: Pour the brownie batter into the prepared pan and smooth the surface. Add dollops of Biscoff cookie butter spread on top and use a knife to swirl it lightly. Sprinkle the extra crushed Biscoff cookie pieces over the batter for added texture.
- Bake: Bake the brownies in the preheated oven for 30 to 35 minutes, or until the top is set and a toothpick inserted into the center comes out with moist crumbs, indicating fudgy brownies.
- Cool and chill: Allow the brownies to cool completely in the pan to set fully, then refrigerate for 1 hour. This cooling step helps the brownies firm up for clean slicing.
- Slice and serve: After chilling, cut the brownies into 16 equal squares and serve.
Notes
- Use room temperature eggs to ensure better mixing and texture.
- To avoid overbaking, check the brownies at 30 minutes; they should be fudgy and moist inside.
- Dutch-processed cocoa powder is preferred for its smooth, less acidic flavor.
- You can substitute all-purpose flour with cake flour for a more tender crumb.
- Store leftovers in an airtight container in the refrigerator for up to 5 days.
