Ingredients
- ½ cup (115g) unsalted butter, melted
- ¾ cup (150g) brown sugar
- ¼ cup (50g) granulated sugar
- 1 large egg, room temperature
- 1 tsp vanilla extract
- ½ cup (120g) Biscoff spread (smooth or crunchy)
- 1 cup (125g) all-purpose flour
- ½ tsp baking powder
- ¼ tsp salt
- ½ cup (90g) white chocolate chips or chunks
- 6–8 Biscoff cookies, crushed or halved
- Optional: sea salt flakes, chopped nuts, extra Biscoff for drizzling
Instructions
- Step 1: Preheat your oven to 350°F (175°C) and line an 8×8-inch pan with parchment paper for easy removal.
- Step 2: In a mixing bowl, combine the melted butter, brown sugar, and granulated sugar. Stir until the mixture is smooth.
- Step 3: Add the egg and vanilla extract to the bowl, then mix until fully combined.
- Step 4: Stir in the Biscoff spread until the batter is creamy and well blended.
- Step 5: Add the flour, baking powder, and salt, mixing gently until just combined. Avoid overmixing to keep the blondies tender.
- Step 6: Fold in the white chocolate chips and half of the crushed Biscoff cookies evenly through the batter.
- Step 7: Pour the batter into the prepared pan and smooth the top with a spatula.
- Step 8: Dollop extra Biscoff spread on top and use a knife to swirl it into the batter. Sprinkle the remaining cookie pieces over the top.
- Step 9: Bake for 25–30 minutes until the edges turn golden and the center is just set but still slightly soft.
- Step 10: Let the blondies cool completely in the pan before slicing into squares. For extra indulgence, drizzle with melted Biscoff or white chocolate before serving.
Tips & Variations
- For a crunchier texture, add chopped nuts like pecans or walnuts to the batter.

- Sprinkle sea salt flakes on top before baking to enhance the caramel flavors.
- Substitute white chocolate with milk or dark chocolate chips if preferred.
Storage

Can I use crunchy Biscoff spread instead of smooth?
Yes, using crunchy Biscoff spread adds extra texture and little cookie crunch throughout the blondies, making them even more delightful.

Add-ins
- ½ cup (90g) white chocolate chips or chunks
- 6–8 Biscoff cookies, crushed or halved
- Optional: sea salt flakes, chopped nuts, extra Biscoff for drizzling
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper to ensure easy removal of the blondies after baking.
- Mix Sugars and Butter: In a mixing bowl, combine the melted unsalted butter with brown sugar and granulated sugar. Stir the mixture until it is smooth and well incorporated.
- Add Egg and Vanilla: Add the egg and vanilla extract to the sugar and butter mixture. Mix thoroughly until fully combined, ensuring a smooth batter base.
- Incorporate Biscoff Spread: Stir in the Biscoff spread until the batter is creamy and evenly blended with the flavors of the spread.
- Combine Dry Ingredients: Add the all-purpose flour, baking powder, and salt to the wet mixture. Mix gently and just until all the dry ingredients are incorporated—avoid overmixing to keep the blondies tender.

Notes

- For crunchier blondies, use crunchy Biscoff spread instead of smooth.
- Store blondies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
- Optionally, serve warm with ice cream for an indulgent dessert.
