Main 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
- Preheat the oven: Set oven to 350°F (180°C) and line an 8-inch (20 cm) square baking pan with parchment paper.
- Melt butter and chocolate: In a heatproof bowl, melt unsalted butter and semi-sweet chocolate together over a double boiler or in short microwave bursts until smooth. Let cool slightly.
- Whisk eggs and sugar: In a large bowl, whisk the 4 room temperature eggs, granulated sugar, and vanilla extract for about 2 minutes until pale and foamy.
- Combine mixtures: Pour the melted chocolate and butter mixture into the egg mixture and stir until smooth and well combined.
- Fold in dry ingredients: Gently fold in the all-purpose flour, Dutch-processed cocoa powder, and salt using a spatula. Avoid overmixing to keep batter dense and fudgy.
- Add crushed Biscoff cookies: Stir in the 10 crushed Lotus Biscoff cookies gently until evenly distributed.
- Prepare pan and add batter: Pour the brownie batter into the prepared pan and smooth the surface with a spatula.
- Swirl cookie butter and top: Dollop the Biscoff cookie butter spread evenly on top in 12 tsp-sized spoonfuls. Lightly swirl it into the batter with a knife and sprinkle the 4 extra Biscoff cookie pieces on top.
- Bake: Bake in preheated oven for 30–35 minutes or until the top is set but the center still has moist crumbs when tested with a toothpick.
- Cool and chill: Allow brownies to cool completely in the pan, then refrigerate for 1 hour to set before slicing into 16 pieces for clean edges and perfect fudgy texture.
- Serve: Enjoy these Biscoff brownies plain or with a scoop of vanilla ice cream for extra indulgence.
Notes
- Use high-quality Biscoff cookie butter for best caramelized flavor and richness.
- Do not overmix the batter to maintain the fudgy, dense texture.
- Line baking pan with parchment paper with overhang for easy lifting and neat slices.
- Test doneness with a toothpick—remove when it has moist crumbs, not dry.
- Cool completely before slicing and chill for best texture and clean cuts.
- Store at room temperature in airtight container for 3–4 days.
- Refrigerate for up to 1 week covered.
- Freeze wrapped slices for up to 3 months; thaw overnight or 30–40 minutes at room temperature.
