Introduction
These chewy Biscoff blondies combine the rich, buttery flavor of classic blondies with the unique caramel notes of Biscoff cookies and white chocolate. Perfect as a cozy dessert or a sweet snack, they’re easy to make and irresistibly delicious.

Ingredients
- ½ cup unsalted butter, melted
- ½ cup granulated sugar
- ¾ cup packed light brown sugar
- 2 teaspoons vanilla extract
- 2 large eggs
- ¼ teaspoon salt
- 1 cup all-purpose flour
- ½ teaspoon baking powder
- 10 Biscoff cookies, chopped
- 4 oz white chocolate, chopped
- ½ cup Biscoff cookie butter
Instructions
- Step 1: Preheat your oven to 350°F. Line an 8×8-inch baking dish with parchment paper, leaving an overhang for easy lifting.
- Step 2: In a large bowl, whisk together the melted butter, granulated sugar, and light brown sugar until the mixture is smooth and glossy.
- Step 3: Add the eggs and vanilla extract to the bowl, whisking until fully blended and slightly thickened.
- Step 4: Stir in the flour, baking powder, and salt gently, just until there are no dry streaks of flour remaining.
- Step 5: Fold in the chopped Biscoff cookies and white chocolate chunks, reserving a few pieces to sprinkle on top later.
- Step 6: Spread half of the batter evenly into the prepared baking pan.
- Step 7: Microwave the Biscoff cookie butter for about 15 seconds until it is pourable. Drizzle it over the batter in the pan, then layer the remaining batter on top. Swirl lightly if you like.
- Step 8: Sprinkle the reserved cookie pieces over the top. Bake for 35–40 minutes, until the blondies are lightly golden and set but still have moist crumbs in the center.
- Step 9: Let the blondies cool completely in the pan before lifting them out using the parchment paper overhang and slicing.
Tips & Variations
- Underbaking slightly helps keep the centers soft and chewy.
- Use a glass baking dish for more even heat distribution and baking.
- For extra gooey blondies, add a handful of white chocolate chips into the batter.
- Try swirling in some creamy peanut butter alongside the Biscoff cookie butter for a nutty twist.
Storage
Store cooled blondies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week or freeze for up to 2 months. Reheat gently in the microwave for 10–15 seconds to soften before serving.

FAQs
Can I use crunchy Biscoff cookie butter instead of smooth?
Yes, crunchy Biscoff cookie butter can be used, but it may add some extra texture and small cookie bits to the blondies, making them slightly crunchier.
What if I don’t have Biscoff cookies on hand?
Speculoos or any spiced caramelized cookies work well as a substitute. You can also use crushed graham crackers or a mix of crushed digestive biscuits for a similar flavor profile.

Wet Ingredients
- ½ cup unsalted butter, melted
- 2 teaspoons vanilla extract
- 2 large eggs
- ½ cup Biscoff cookie butter
Dry Ingredients
- ½ cup granulated sugar
- ¾ cup packed light brown sugar
- 1 cup all-purpose flour
- ¼ teaspoon salt
- ½ teaspoon baking powder
Mix-Ins
- 10 Biscoff cookies, chopped
- 4 oz white chocolate, chopped
Instructions
- Prepare the Oven and Pan: Preheat your oven to 350°F (177°C). Line an 8×8-inch baking dish with parchment paper, leaving an overhang on the sides for easy removal of the blondies after baking.
- Combine Butter and Sugars: In a large bowl, whisk together the melted unsalted butter, granulated sugar, and light brown sugar until the mixture is smooth and has a glossy texture.
- Add Eggs and Vanilla: Whisk in the eggs and vanilla extract thoroughly until fully blended and the batter slightly thickens.
- Mix in Dry Ingredients: Add the all-purpose flour, baking powder, and salt to the wet ingredients. Stir gently just until no dry streaks remain, being careful not to overmix to maintain a tender texture.
- Fold in Mix-Ins: Gently fold in the chopped Biscoff cookies and white chocolate chunks, reserving some pieces for sprinkling on top later.
- Layer the Batter: Evenly spread half of the batter into the prepared baking dish, smoothing the surface with a spatula.
- Add Cookie Butter and Finish Batter: Microwave the Biscoff cookie butter for 15 seconds to make it pourable. Drizzle the warmed cookie butter over the batter in the pan. Top with the remaining batter and lightly swirl the cookie butter into it if desired for a marbled effect.
- Bake and Cool: Sprinkle the reserved chopped cookie pieces on top of the batter. Bake in the preheated oven for 35 to 40 minutes, until the blondies are lightly golden on top and set with moist crumbs inside. Allow cooling completely in the pan before lifting out with the parchment overhang and slicing into bars.
Notes
- Slight underbaking helps keep the centers soft and chewy.
