Crust
- 1 1/2 cups crushed Biscoff cookies (about 20 cookies, 155g)
- 1/4 cup salted butter, melted and cooled (56g)
Brownie Batter
- 2 large eggs, room temperature (112g)
- 1/2 cup granulated sugar (100g)
- 1/2 cup packed light brown sugar (100g)
- 1/2 cup salted butter, melted and cooled (113g)
- 2 tsp vanilla extract or vanilla bean paste (8g)
- 1/2 cup all-purpose flour (65g)
- 1/3 cup unsweetened baking cocoa (33g)
- 1/4 tsp baking powder (>1g)
Topping
- 1/3 cup smooth Biscoff spread (80g)
- Prepare Pan and Crust: Preheat your oven to 350°F (175°C). Line an 8 x 8-inch baking pan with parchment paper to prevent sticking. In a bowl, mix the crushed Biscoff cookies with 1/4 cup melted butter until combined, then press this mixture firmly into the bottom of the prepared pan to form an even crust.
- Mix Wet Ingredients: In a large bowl, combine the 2 eggs, granulated sugar, and brown sugar. Use a hand or stand mixer on high speed for about 1 minute until the mixture is lighter in color and creamy in texture.
- Add Butter and Vanilla: With the mixer on medium speed, blend in the melted and cooled 1/2 cup butter along with the 2 teaspoons vanilla extract until fully incorporated.
- Combine Dry Ingredients: Sift the all-purpose flour, unsweetened cocoa powder, and baking powder together to remove any lumps and ensure even spreading through the batter.
- Fold Dry into Wet: Gently fold the sifted dry ingredients into the wet mixture using a rubber spatula. Be careful not to overmix, just fold until no streaks remain.
- Assemble Brownie Layer: Pour the brownie batter over the Biscoff crust in the pan, spreading it evenly with a spatula to cover the crust completely.
- Add Biscoff Swirl: Warm the 1/3 cup of Biscoff spread in the microwave for about 5-10 seconds until soft. Drop spoonfuls of it on top of the brownie batter and use a butter knife to swirl it into a pretty marbled pattern.
- Bake: Place the pan in the preheated oven and bake for 22 to 25 minutes. Check doneness by inserting a toothpick in the center; it should come out mostly clean with a few moist crumbs. Approximately 23 minutes works well in most ovens.
- Cool Completely: Remove the brownies from the oven and allow them to cool fully in the pan before cutting into squares to ensure clean slices and set texture.
Notes
- Ensure the melted butter is cooled before mixing with eggs to prevent cooking them.
- Use room temperature eggs for better mixing and texture.
- Do not overbake; brownies should remain fudgy inside.
- Swirling the Biscoff spread creates an attractive marbled effect but avoid too much mixing to preserve distinct swirls.
- Parchment paper lining is key for easy removal and cutting.
- If unavailable, Biscoff cookies and spread can sometimes be substituted with speculoos cookie butter alternatives.
