For the Blondies
- ¾ cup (1½ sticks or 170g) unsalted butter
- ½ cup (140g cookie) butter spread (I used Biscoff brand)
- 1 cup (200g) brown sugar
- ½ cup (100g) granulated sugar
- 2 large eggs (at room temperature)
- 1 teaspoon vanilla extract

- 1¼ teaspoons baking powder
- ½ teaspoon salt
- ¼ teaspoon cinnamon
- ⅔ cup (130g) white chocolate chips
- 6-8 Biscoff cookies
- 2 Tablespoons (35g) cookie butter spread
How to Make Biscoff Blondies
Step 1: Preheat the Oven
- Preheat your oven to 350°F.
- Lightly grease a 9” x 9” square pan with cooking spray.
- Line the pan with parchment paper to create a sling, leaving an overhang on all four sides.
Step 2: Prepare the Batter
- Melt the unsalted butter and allow it to cool slightly.
- In a large mixing bowl, combine the melted butter, cookie butter spread, brown sugar, and granulated sugar.
- Whisk well until all ingredients are combined.
Step 3: Mix in Eggs and Dry Ingredients
- Add the eggs and vanilla extract to the mixture; mix together for about 30 seconds.
- Gradually add in the all-purpose flour, baking powder, salt, and cinnamon.
- Stir with a spatula until only a few streaks of flour remain.
- Fold in the white chocolate chips gently.
Step 4: Bake Your Blondies
- Pour the batter into the prepared pan and spread it evenly using an offset spatula.
- Top with broken pieces of Biscoff cookies.
- Bake for 30-35 minutes or until the center is set and edges turn golden brown. A toothpick inserted should come out with moist crumbs but no wet batter.

- Cut into 16 equal squares, serve, and enjoy!
How to Serve Biscoff Blondies
Biscoff Blondies are a delightful treat that can be enjoyed in various ways. Whether you prefer them warm with a scoop of ice cream or as part of a dessert platter, there’s no wrong way to serve these rich and chewy bars.
Pair with Ice Cream
- Vanilla Ice Cream – The classic vanilla flavor complements the spiced notes of Biscoff.
- Salted Caramel Ice Cream – Adds a sweet and salty contrast that enhances the blondies’ richness.
Enjoy with Coffee
- Espresso – A shot of espresso pairs well, balancing the sweetness of the blondies.
- Flavored Lattes – Cinnamon or caramel lattes offer a cozy drink option.
Create a Dessert Platter
- Fresh Fruits – Slices of apple or pear add freshness and balance out the sweetness.
- Mini Cheesecakes – A variety of mini cheesecakes can make your dessert spread more exciting.
Drizzle with Chocolate Sauce
- Dark Chocolate Sauce – A drizzle over the top provides an extra layer of indulgence.
- White Chocolate Drizzle – Enhances the white chocolate chips already in the blondies.
Top with Whipped Cream
- Sweetened Whipped Cream – Lightly sweetened whipped cream adds a fluffy texture to every bite.
- Flavored Whipped Cream – Consider vanilla or cinnamon for an extra flavor kick.

How to Perfect Biscoff Blondies
Perfecting your Biscoff Blondies will ensure they are soft, chewy, and packed with flavor. Here are some tips to help you achieve the best results.
- Use Room Temperature Ingredients – Eggs should be at room temperature for better mixing, resulting in a smoother batter.
- Don’t Overmix – Mixing just until combined helps maintain a fudgy texture; stop when you still see streaks of flour.
- Check for Doneness – Use a toothpick to test; it should come out with moist crumbs but not wet batter for perfect blondies.
- Cool Completely Before Cutting – Letting them cool allows them to set properly, making cutting easier and cleaner.
- Add Extra Toppings – Consider sprinkling sea salt on top before serving for added flavor and contrast.
- Store Properly – Keep them in an airtight container at room temperature to maintain their softness.
Best Side Dishes for Biscoff Blondies
When serving Biscoff Blondies, pairing them with complementary side dishes can elevate your dessert experience. Here are some fantastic options to consider:
- Vanilla Yogurt – A creamy addition that balances sweetness while adding a slight tang.
- Fruit Salad – A mix of berries and citrus fruits provides freshness and acidity against the rich blondies.
- Chocolate Fondue – Dip pieces of blondie into melted chocolate for an indulgent treat.
- Cheese Platter – Soft cheeses like brie pair beautifully with sweet flavors, creating a delightful contrast.
- Nut Mix – A blend of salted nuts adds crunch and saltiness that complements the chewy blondies.
- Coconut Whipped Cream – Light and airy, this topping adds tropical flair that pairs well with cookie butter flavors.
- Trail Mix Bars – Homemade trail mix bars offer additional texture and flavor variation alongside the sweet blondies.
Common Mistakes to Avoid
When making Biscoff Blondies, it’s easy to overlook some key details. Here are common mistakes to watch out for:
- Using cold eggs: Cold eggs can affect the texture of your blondies. Always use room temperature eggs for a smoother batter.
- Overmixing the batter: Overmixing can lead to tough blondies. Mix just until combined for a soft and chewy result.
- Not greasing the pan: Skipping this step might cause your blondies to stick. Always grease and line your baking pan for easy removal.
- Measuring flour incorrectly: Using too much flour can make blondies dense. Use the spoon and level method for accurate measurements.
- Baking too long: Overbaking can dry out your blondies. Keep an eye on them, and remove once they are just set in the middle.
