Ingredients

Scale

Base Layer

  • 3/4 cup (200 g) Biscoff cookie butter

Brownie Batter

  • 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

Toppings

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

Instructions

  1. Prepare the Biscoff cookie butter base: Line an 8×8 inch square metal baking pan with a large piece of parchment paper, creasing the bottom edges to form the shape of the pan for easy removal later. Evenly spread 3/4 cup of Biscoff cookie butter inside the creased edges. Freeze the pan until the cookie butter layer is completely firm before proceeding.
  2. Preheat oven and prepare pan: Line the pan again with parchment paper that hangs over all four sides for easy lift-out of the finished brownies. Preheat your oven to 350°F (180°C).
  3. Mix sugars, eggs, and vanilla: In a bowl, whisk together the brown sugar, granulated sugar, eggs, egg yolk, and vanilla extract until fully combined and slightly thickened.
  4. Melt butter and chocolate: In a small saucepan or microwave-safe bowl, melt the unsalted butter with the semi-sweet chocolate chips until smooth. Whisk in the cocoa powder until fully incorporated.
  5. Combine chocolate mixture with egg mixture: Whisk the melted chocolate mixture into the egg and sugar mixture until just combined, avoiding overmixing.
  6. Fold in dry ingredients: Gently fold the all-purpose flour, espresso powder, and fine sea salt into the batter, mixing just until incorporated to maintain a tender texture.
  7. Assemble brownies: Pour half of the brownie batter (around 340 grams) into the prepared pan, spreading evenly to the edges. Remove the frozen cookie butter block from the freezer, peel off the parchment paper on top, and place it gently over the batter layer. Pour the remaining batter on top and spread it to the edges evenly.
  8. Add toppings: Break 4-5 Biscoff cookies into pieces and press them onto the top of the brownie batter. Warm about 2 tablespoons of Biscoff cookie butter in the microwave for 15-20 seconds until runny, then drizzle it over the cookie pieces and batter surface.
  9. Bake: Place the pan in the preheated oven and bake for 30-40 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs. Avoid overbaking for fudgy brownies.
  10. Cool and serve: Allow the brownies to cool completely in the pan set on a wire rack. Optionally, drizzle more cookie butter on top just before cutting. Use the parchment paper edges to lift the brownies out, then cut and enjoy.
  11. Storage: Store any leftovers in an airtight container at room temperature for 2-3 days or freeze for up to 1 month.

Notes

  • Use a metal 8×8 inch square baking pan for best results; parchment paper lining with creased edges makes removing brownies easy.
  • Measure flour properly by spooning it into your cup and leveling off with a knife to avoid dense brownies.
  • Ensure the cookie butter base is frozen firm before pouring batter on top to maintain distinct layers.
  • Espresso powder enhances the chocolate flavor but can be omitted if unavailable.
  • Biscoff cookies on top add delightful crunch and extra caramel-cinnamon flavor contrast.
