Ingredients
Cookie butter meets blondies in these soft and chewy Biscoff Blondies, sprinkled with white chocolate throughout. They are sweet, spiced, and indulgent.
For the Base
- 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
Dry Ingredients
- 2 cups (240g) all-purpose flour
- 1¼ teaspoons baking powder
- ½ teaspoon salt
- ¼ teaspoon cinnamon
Add-ins
- 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 your 9” x 9” square pan with cooking spray. Line it with parchment paper, leaving an overhang on all four sides to make it easier to lift the blondies out later.
Step 2: Prepare the Batter
- Melt the unsalted butter in a saucepan over low heat or in the microwave. 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 everything is combined.
- Add in the eggs and vanilla extract. Mix together for about 30 seconds until fully incorporated.
Step 3: Combine Dry Ingredients
- Add the all-purpose flour, baking powder, salt, and cinnamon into the mixture.
- Mix with a spatula until only a few streaks of flour remain visible.
- Gently fold in the white chocolate chips until evenly distributed.
Step 4: Bake the Blondies
- Pour the batter into your prepared pan, spreading it evenly with an offset spatula.
- Top with broken pieces of Biscoff cookies for extra crunch.
- Bake for 30-35 minutes until the center is just set and edges are golden brown. A toothpick inserted should come out with a few moist crumbs.
Step 5: Finishing Touches
Allow the blondies to cool completely in the pan. Melt the remaining cookie butter spread and drizzle it over the top before cutting into 16 equal squares. Serve these delicious Biscoff Blondies at your next gathering or enjoy them as a personal treat!

How to Perfect Biscoff Blondies
To achieve the perfect texture and flavor in your Biscoff Blondies, follow these helpful tips.
-
Use Room Temperature Ingredients: Ensure your eggs and butter are at room temperature for better mixing and smoother batter.
-
Don’t Overmix: Mix just until combined after adding flour. Overmixing can lead to dense blondies instead of soft ones.
-
Check Oven Temperature: Use an oven thermometer to confirm that your oven is at 350°F. An accurate temperature ensures even baking.
-
Cool Completely Before Cutting: Allow the blondies to cool completely before cutting. This helps them set properly and makes slicing easier.
Best Side Dishes for Biscoff Blondies
When serving Biscoff Blondies, consider pairing them with complementary side dishes that enhance their flavors. Here are some great options:
- Vanilla Ice Cream: A classic pairing that adds creamy richness to the sweet blondies.
- Caramel Sauce: A drizzle of warm caramel sauce elevates the dessert’s sweetness and introduces a buttery flavor.
- Fresh Berries: Strawberries or raspberries provide a tart contrast that balances the sweet, spiced blondie.
- Whipped Cream: Light and airy whipped cream adds texture and serves as a neutral flavor complement.
- Chocolate Sauce: For chocolate lovers, a drizzle of chocolate sauce will create an indulgent combination.
- Coffee or Espresso: The bitterness of coffee enhances the sweetness of the blondies, making for an enjoyable contrast.
- Fruit Salad: A light fruit salad can refresh your palate between bites of rich blondie.
- Nut Butter Spread: A smear of almond or peanut butter can add nutty notes that pair well with cookie butter flavors.
Common Mistakes to Avoid
Baking Biscoff Blondies can be delightful, but a few common mistakes can affect the final result. Here are some pitfalls to steer clear of:
- Using cold ingredients: Always use room temperature eggs and melted butter. Cold ingredients may not combine well, leading to a dense texture.
- Overmixing the batter: Mix just until combined. Overmixing can create tough blondies instead of soft and chewy ones.
- Skipping the parchment paper: Lining your pan with parchment makes it easier to remove the blondies without breaking them. Don’t skip this step!
- Not measuring flour correctly: Use the spoon and level method for accurate measurements. Too much flour can lead to dry blondies.
- Ignoring baking time: Keep an eye on your blondies as they bake. Overbaking will result in a dry texture, while underbaking may leave them gooey in the center.
