Ingredients

Scale

Brownie Base

  • 1 cup (226g) unsalted butter, cut into pieces
  • 8 ounces (225g) dark chocolate (60-70% cocoa), coarsely chopped
  • 1 ½ cups (300g) granulated sugar
  • ½ cup (100g) light brown sugar, packed
  • 4 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 cup (120g) all-purpose flour
  • ½ cup (45g) unsweetened cocoa powder
  • ½ teaspoon fine sea salt

Biscoff Swirl and Topping

  • 1 cup (280g) creamy Biscoff cookie butter spread
  • 1012 Lotus Biscoff cookies, roughly crushed (optional)

Instructions

  1. Preheat and Prepare Pan: Preheat oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang for easy removal later, and grease the paper lightly. Gather and measure all ingredients, ensuring the eggs are at room temperature for optimal mixing.
  2. Melt Butter and Chocolate: Melt the butter and chopped dark chocolate together using 30-second intervals in a microwave or a double boiler until smooth. Allow the mixture to cool for 5-10 minutes to avoid cooking the eggs when combined.
  3. Mix Sugars and Eggs: In a large bowl, vigorously whisk the granulated sugar, light brown sugar, and room-temperature eggs for 3-5 minutes until the mixture becomes light, frothy, and well combined. Stir in the vanilla extract.
  4. Combine Chocolate with Egg Mixture: Gently fold the slightly cooled butter and chocolate mixture into the egg and sugar mixture, mixing just until combined to maintain airiness.
  5. Incorporate Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, and fine sea salt. Gently fold these dry ingredients into the wet chocolate mixture in two additions, stirring carefully until just combined. Avoid overmixing to keep the brownies tender.
  6. Pour Batter into Pan: Spread the brownie batter evenly into the prepared baking pan, smoothing the surface for even baking.
  7. Prepare Biscoff Swirl: Warm the creamy Biscoff cookie butter slightly either in the microwave for 20-30 seconds or over very low heat on the stovetop until it reaches a pourable, honey-like consistency.
  8. Create Swirls: Dollop spoonfuls of the warmed Biscoff spread evenly over the brownie batter. Using a butter knife or skewer, gently swirl the Biscoff through the batter to create attractive marbled patterns without mixing too deeply to the bottom.
  9. Add Cookie Crumble (Optional): Sprinkle the roughly crushed Lotus Biscoff cookies evenly over the swirled batter to add a crunchy texture and extra flavor layers.
  10. Bake: Bake in the preheated oven for 28-35 minutes. The brownies are done when the edges look set and the center is slightly jiggly. Test doneness by inserting a wooden skewer or toothpick into the center, avoiding Biscoff swirls; it should come out with moist crumbs but no wet batter.
  11. Cool and Serve: Allow the brownies to cool completely in the pan on a wire rack for at least 2-3 hours. Once cool, use the parchment paper overhang to lift the brownies from the pan. Cut into squares with a sharp knife, cleaning the knife between cuts for neat edges.

Notes

  • Ensure eggs are at room temperature to achieve a light, aerated batter when whisked with sugars.
  • Do not overmix the batter once dry ingredients are added to maintain fudgy texture.
  • Warming the Biscoff spread makes it easier to swirl and distribute evenly in the batter.
  • Baking time may vary slightly depending on your oven; check for moist crumbs rather than fully dry batter for best fudgy results.
  • Let brownies cool fully before cutting to get clean squares and prevent crumbling.
  • Optional crushed Lotus cookies add texture but can be omitted for a smoother brownie top.
