Ingredients

Scale

Chocolate Base

  • 250 g (8.8 oz / 1 ½ cups) baking chocolate or semi-sweet chocolate chips
  • 115 g (1 stick) unsalted butter

Dry Ingredients

  • 90 g (¾ cup) all-purpose or cake flour
  • 30 g (¼ cup) unsweetened cocoa powder (Dutch-processed preferred)
  • ½ tsp salt

Wet Ingredients

  • 4 large eggs, at room temperature
  • 200 g (1 cup) granulated sugar
  • 1 ½ tsp pure vanilla extract

Biscoff Additions

  • 10 crushed Lotus Biscoff cookies (plus 4 extra for topping)
  • 12 tsp Biscoff cookie butter spread

Instructions

  1. Prepare Pan and Oven: Preheat the oven to 350°F (180°C) and line an 8-inch (20 cm) square baking pan with parchment paper to prevent sticking and allow easy removal of the brownies.
  2. Melt Chocolate and Butter: Melt the butter and baking chocolate together in a heatproof bowl set over a double boiler, or heat them in short bursts in the microwave, stirring until the mixture is smooth and fully combined.
  3. Combine Eggs, Sugar, and Vanilla: In a separate bowl, whisk the eggs, granulated sugar, and vanilla extract vigorously for about 2 minutes until the mixture turns pale and slightly foamy, ensuring a light texture in the final brownies.
  4. Mix Chocolate into Egg Mixture: Pour the melted chocolate and butter mixture into the egg mixture and stir gently until smooth and fully incorporated.
  5. Fold in Dry Ingredients: Using a spatula, carefully fold the flour, cocoa powder, and salt into the chocolate batter. Mix just until combined to avoid overmixing and tough brownies.
  6. Add Crushed Biscoff Cookies: Fold the crushed Biscoff cookies into the batter, distributing them evenly without overmixing to maintain texture contrast.
  7. Prepare for Baking: Pour the batter into the prepared pan and smooth the surface with a spatula. Add dollops of Biscoff cookie butter spread on top and swirl lightly with a knife. Sprinkle the extra crushed Biscoff cookie pieces over the surface for added crunch.
  8. Bake: Place the baking pan in the oven and bake for 30–35 minutes. The brownies are done when the top is set but a toothpick inserted in the center comes out with moist crumbs, indicating fudgy doneness.
  9. Cool and Chill: Remove the pan from the oven and allow the brownies to cool completely in the pan. Once cool, refrigerate for 1 hour to set the texture before slicing into 16 squares for serving.

Notes

  • For best results, use high-quality baking chocolate or semi-sweet chocolate chips.
  • Room temperature eggs help ensure a smoother batter and better incorporation.
  • Do not overmix the batter after adding flour to maintain a fudgy texture.
  • Chilling the brownies before slicing helps them hold their shape properly.
  • Use Dutch-processed cocoa powder for a richer chocolate flavor and darker color.
