Biscoff Cookie Butter Blondies Recipe
Introduction
Biscoff Blondies are a delightful twist on the classic blondie, packed with chunks of crunchy Biscoff cookies and swirls of creamy cookie butter. Topped with white chocolate, they offer a perfect balance of sweetness and texture that’s sure to satisfy any sweet tooth.

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
- 4 oz. bar of white chocolate (roughly chopped)
- ½ cup Biscoff (cookie butter)
Instructions
- Step 1: Preheat the oven to 350°F. Line an 8×8-inch glass baking dish with parchment paper and set aside.
- Step 2: In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until combined.
- Step 3: Add vanilla extract and eggs; continue whisking until the mixture is smooth and fully combined.
- Step 4: Stir in salt, flour, and baking powder just until incorporated—avoid overmixing.
- Step 5: Chop or break the Biscoff cookies into chunks. Fold the cookie pieces and white chocolate into the blondie batter, reserving a few pieces for topping if desired.
- Step 6: Spread half of the batter evenly into the prepared baking dish.
- Step 7: Microwave the Biscoff cookie butter for about 15 seconds until pourable. Drizzle it evenly over the bottom layer of batter.
- Step 8: Top with the remaining batter and press additional cookie pieces and white chocolate on top for added texture.
- Step 9: Bake for 35 to 40 minutes, or until the top is golden brown and a knife inserted in the center comes out clean or with a few crumbs clinging. The center should not be wet.
- Step 10: Let the blondies cool completely, then lift them out using the parchment paper edges. Cut into bars and serve.
Tips & Variations
- For extra fudgy blondies, slightly underbake by a couple of minutes and allow them to set as they cool.
- Try swapping white chocolate for dark or milk chocolate chunks for a different flavor profile.
- Use crunchy Biscoff cookie butter for added texture in the middle layer.
Storage
Store blondies in an airtight container at room temperature for up to 3 days. For longer storage, keep them refrigerated for up to a week or freeze for up to 3 months. Reheat briefly in the microwave to soften before serving.

FAQs
Can I use a different cookie instead of Biscoff?
Yes, you can substitute with other spiced or cinnamon-flavored cookies, but Biscoff gives a unique flavor that pairs beautifully with white chocolate.
How do I know when the blondies are done?
The blondies are done when the top is golden brown and a knife inserted near the center comes out clean or with just a few moist crumbs. The center should be set but still moist, not wet or runny.

Ingredients
Blondie Batter
- 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
Mix-ins and Topping
- 10 Biscoff cookies, chopped into chunks
- 4 oz bar of white chocolate, roughly chopped
- ½ cup Biscoff cookie butter
Instructions
- Preheat and prepare baking dish: Preheat the oven to 350°F (177°C). Line an 8×8 inch glass baking dish with parchment paper, allowing an overhang for easy removal later, and set aside.
- Mix wet ingredients: In a large mixing bowl, whisk together the melted unsalted butter, granulated sugar, and light brown sugar until smooth and combined.
- Add eggs and vanilla: Whisk in the vanilla extract and eggs until fully incorporated and the mixture is homogenous.
- Incorporate dry ingredients: Add the salt, all-purpose flour, and baking powder to the wet mixture. Stir gently just until everything is combined to avoid overmixing.
- Add cookie and chocolate chunks: Fold in the chopped Biscoff cookies and white chocolate pieces gently, keeping some chunks aside for topping if desired.
- Layer the batter: Spread half of the blondie batter evenly into the prepared baking dish, smoothing the surface.
- Swirl Biscoff cookie butter: Microwave the Biscoff cookie butter for about 15 seconds until pourable. Drizzle this evenly over the bottom layer of blondie batter in the baking dish.
- Top with remaining batter: Spoon and spread the remaining blondie batter on top of the cookie butter layer, then press the reserved cookie and chocolate chunks gently onto the surface for added texture.
- Bake blondies: Bake in the preheated oven for 35-40 minutes or until the tops are golden brown and a knife inserted into the center comes out clean or with only a few moist crumbs. The center should not be wet or raw.
- Cool and serve: Allow the blondies to cool completely in the baking dish. Using the parchment overhang, lift the blondies out and transfer to a cutting board. Cut into bars and serve.
Notes
- For best texture, avoid overmixing the batter once flour is added.
- If white chocolate chunks are too large, chop smaller to ensure even melting.
- Biscoff cookie chunks add a delightful crunch; feel free to reserve more for topping.
- Cooling completely is crucial for clean slicing and maintaining shape.
- Store blondies in an airtight container at room temperature for up to 3 days or refrigerate for extended freshness.
