Ingredients

Scale

Wet 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

Dry Ingredients

  • 90 g (¾ cup) all-purpose or cake flour
  • 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

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. incorporate Biscoff cookies: Gently fold the crushed Lotus Biscoff cookies into the batter until evenly distributed.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
