Ingredients

Scale

Brownie Base

  • 3/4 cup (200 g) Biscoff cookie butter
  • 1/2 cup (100 g) light or dark brown sugar, packed
  • 1/2 cup (100 g) granulated sugar
  • 2 large eggs (about 100 g)
  • 1 large egg yolk (about 18 g)
  • 1 tablespoon vanilla extract
  • 10 tablespoons (140 g) unsalted butter
  • 2/3 cup + 1/4 cup (156 g) semi-sweet chocolate chips
  • 1/4 cup (25 g) unsweetened Dutch cocoa powder
  • 2/3 cup + 1 tablespoon (90 g) all-purpose flour
  • 1 teaspoon espresso powder
  • 1/2 teaspoon fine sea salt

Topping

  • 45 Biscoff cookies, broken into pieces
  • Extra cookie butter (about 2 tablespoons) for drizzling

Instructions

  1. Prepare Pan and Chill Cookie Butter Layer: Press a large piece of parchment paper into an 8×8-inch square metal baking pan, creasing the edges so you can see the pan’s outline after removing. Evenly spread 3/4 cup (200 g) Biscoff cookie butter inside the creased edges. Place the pan in the freezer until the cookie butter layer is completely firm before proceeding.
  2. Preheat Oven and Line Pan: Line the baking pan with parchment paper extending off all four sides for easy removal. Preheat the oven to 350°F (180°C).
  3. Mix Sugar and Eggs: Whisk together 1/2 cup light or dark brown sugar, 1/2 cup granulated sugar, 2 large eggs, 1 large egg yolk, and 1 tablespoon vanilla extract until well combined and smooth.
  4. Melt Butter and Chocolate: Gently melt 10 tablespoons unsalted butter and 2/3 cup + 1/4 cup semi-sweet chocolate chips together until smooth. Whisk in 1/4 cup unsweetened Dutch cocoa powder until fully incorporated and combined.
  5. Combine Wet Mixtures: Whisk the melted chocolate mixture into the sugar and egg mixture until just combined to form a rich batter.
  6. Fold Dry Ingredients: Fold in 2/3 cup + 1 tablespoon all-purpose flour, 1 teaspoon espresso powder, and 1/2 teaspoon fine sea salt until just combined without overmixing.
  7. Layer the Batter and Cookie Butter: Pour half of the brownie batter (about 340 grams) into the prepared pan and spread evenly to the edges. Remove the frozen cookie butter square from the freezer and peel off its parchment paper. Carefully place the frozen cookie butter layer on top of the batter in the pan.
  8. Add Remaining Batter: Pour the remaining batter evenly over the cookie butter layer and spread it smoothly to cover.
  9. Add Cookie Topping and Drizzle: Break 4-5 Biscoff cookies into pieces and press them evenly onto the top of the batter. Warm about 2 tablespoons of extra cookie butter in the microwave for 15-20 seconds until runny, then drizzle it over the cookie pieces for extra flavor and shine.
  10. Bake and Cool: Bake in the preheated oven for 30-40 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Allow the brownies to cool completely on a wire rack before removing from the pan using the parchment paper edges.
  11. Optional Serving: Drizzle with more warm cookie butter if desired before cutting. Store leftovers in an airtight container at room temperature for 2-3 days or freeze for up to 1 month.

Notes

  • Use an 8×8-inch metal baking pan for even baking and best results.
  • Ensure the cookie butter layer is fully chilled and firm before adding batter to prevent mixing layers.
  • When measuring flour, spoon into the measuring cup and level off for accuracy.
  • Brownies are best enjoyed at room temperature or slightly warm with extra cookie butter drizzle.
  • Store leftovers in an airtight container to maintain freshness.
  • Freezing brownies extends their shelf life up to 1 month; thaw at room temperature before serving.
