Biscoff Blondies Recipe
Introduction
Biscoff Blondies are a delightful twist on classic blondies, infused with the rich, caramelized flavor of Biscoff spread and topped with crunchy cookie pieces. These treats are perfect for anyone who loves a chewy, sweet dessert with a bit of texture and warmth.

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 the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper to prevent sticking.
- Step 2: In a mixing bowl, combine the melted butter, brown sugar, and granulated sugar. Stir until the mixture is smooth and well blended.
- Step 3: Add the egg and vanilla extract to the bowl. Mix thoroughly until fully incorporated.
- Step 4: Stir in the Biscoff spread until the batter is creamy and evenly combined.
- Step 5: Add the all-purpose flour, baking powder, and salt. Gently mix 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 for extra texture.
- Step 7: Pour the batter into the prepared pan and smooth the top with a spatula.
- Step 8: Dollop extra Biscoff spread on the surface and swirl it gently with a knife. Sprinkle the remaining cookie pieces evenly over the top.
- Step 9: Bake for 25–30 minutes, until the edges turn golden and the center is just set but still soft.
- Step 10: Allow the blondies to cool completely in the pan before slicing into squares. Drizzle with melted Biscoff or white chocolate if desired for an extra touch of sweetness.
Tips & Variations
- Use crunchy Biscoff spread for added texture inside the blondies.
- Sprinkle a pinch of sea salt flakes on top before baking to balance the sweetness.
- Substitute white chocolate with dark or milk chocolate chips for a richer flavor.
- Add chopped nuts such as pecans or walnuts for a nutty crunch.
- If you prefer, swirl in peanut butter alongside the Biscoff spread for a delicious twist.
Storage
Store the blondies in an airtight container at room temperature for up to 4 days. For longer storage, refrigerate up to a week or freeze for up to 3 months. Reheat briefly in the microwave to soften before serving if desired.

FAQs
Can I use crunchy Biscoff spread instead of smooth?
Yes, using crunchy Biscoff spread will add extra texture with bits of cookie throughout the blondies, enhancing their chewiness and flavor.
How do I know when the blondies are done baking?
The edges will be golden and set, while the center should still be slightly soft but not raw. A toothpick inserted in the center should come out with a few moist crumbs but not wet batter.
