Ingredients
Brownie Batter
- 1 cup salted butter (melted and slightly cooled)
- 3 large eggs (room temperature)
- 2 tsp pure vanilla extract
- ⅔ cup granulated sugar
- 1 cup brown sugar (packed)
- ¾ cup unsweetened cocoa powder
- 1 cup all-purpose flour
- ½ tsp espresso powder (optional; alternatively, 1 tbsp strong coffee)
- ½ teaspoon salt
- 2/3 cup Biscoff spread (well chilled, plus more for topping)
Topping
- Extra Biscoff spread (for drizzle)
- Crumbled Biscoff cookies
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Grease a 9×9-inch baking pan thoroughly with baking spray to prevent sticking.
- Mix Butter and Sugars: In a large mixing bowl, whisk together the melted and slightly cooled salted butter with both granulated and brown sugars until well combined and smooth.
- Add Eggs and Vanilla: Incorporate the room temperature eggs and vanilla extract into the butter-sugar mixture, whisking vigorously until the batter becomes light and fluffy.
- Sift Dry Ingredients: Sift the unsweetened cocoa powder, all-purpose flour, espresso powder (or coffee alternative), and salt over the wet ingredients and gently fold in with a rubber spatula just until combined, avoiding over-mixing.
- Layer Batter and Biscoff Spread: Pour half of the brownie batter evenly into the prepared pan, smoothing it to the edges. Dollop spoonfuls of the chilled Biscoff spread over this layer.
- Top with Remaining Batter: Spoon the remaining batter over the Biscoff layer and gently smooth it out. Optionally, add extra spoonfuls of Biscoff spread on top for a more decadent swirl.
- Bake: Bake in the preheated oven for 30-35 minutes, or until the center is set when tested with a toothpick. For extra gooey brownies, check at 25 minutes and remove when the center is just barely set.
- Cool: Allow the brownies to cool in the pan for 20 minutes, then carefully transfer them to a wire rack to cool completely before adding toppings.
- Drizzle and Garnish: Melt additional Biscoff spread in the microwave for 20-30 seconds and stir until smooth. Drizzle over the cooled brownies and sprinkle generously with crumbled Biscoff cookies for a crunchy finish.
Notes
- Ensure the Biscoff spread is well chilled before dolloping to create thicker swirls and prevent it from mixing too deeply into the batter.
- For a richer coffee flavor, substitute espresso powder with a tablespoon of freshly brewed strong coffee.
- Do not over-bake to maintain fudginess; brownies continue to set as they cool.
- Use room temperature eggs for better batter incorporation and texture.
- Store brownies in an airtight container at room temperature for up to 4 days or refrigerate for up to a week.
