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, ensuring there’s an overhang on all four sides.
Step 2: Prepare the Batter

- In a large mixing bowl, add the melted butter, cookie butter spread, brown sugar, and granulated sugar.
- Whisk well until all ingredients are combined.
Step 3: Mix Wet Ingredients
- Add in the eggs and vanilla extract to the bowl.
- Mix everything together for about 30 seconds until blended.
Step 4: Combine Dry Ingredients
- Gradually add in the flour, baking powder, salt, and cinnamon.
- Mix gently with a spatula until only a few streaks of flour remain.
- Fold in the white chocolate chips carefully.
Step 5: Bake the Blondies
- Pour the batter into the prepared pan and spread it evenly with an offset spatula.
- Top with broken pieces of Biscoff cookies.
- Bake for about 30–35 minutes, or until the center is just set and edges are golden brown.

- Cut into 16 equal squares, serve, and enjoy!
How to Serve Biscoff Blondies
Biscoff Blondies are incredibly versatile and can be enjoyed in various ways. Whether you want a simple dessert or a more elaborate treat, here are some serving suggestions that enhance their delightful flavors.
With Vanilla Ice Cream
- This classic pairing adds creaminess and balances the sweet, spiced notes of the blondies. Simply scoop some vanilla ice cream on top or serve it on the side.
Drizzled with Caramel Sauce
- A warm drizzle of caramel sauce adds an extra layer of sweetness and a beautiful presentation. It complements the cookie butter flavor perfectly.
Topped with Whipped Cream
- Light and airy whipped cream can elevate your Biscoff Blondies. Top them right before serving for a fresh touch.
Paired with Fresh Fruit
- Serve alongside fresh berries or sliced bananas for a refreshing contrast. The tartness of the fruit pairs well with the sweetness of the blondies.
As a Dessert Platter
- Create a dessert platter featuring your Biscoff Blondies, along with other treats like brownies and cookies. It offers variety and is perfect for gatherings.

How to Perfect Biscoff Blondies
Achieving the perfect Biscoff Blondies requires attention to detail during preparation. Follow these tips to ensure your blondies turn out soft, chewy, and delicious every time.
- Use Room Temperature Eggs: This helps create a smoother batter, leading to better texture in your blondies.
- Don’t Overmix the Batter: Mixing just until combined prevents dense blondies. Stop when you see only a few streaks of flour.
- Check for Doneness Early: Start checking around 30 minutes to avoid overbaking. The edges should be golden brown while the center remains slightly underbaked.
- Cool Completely Before Cutting: Allowing the blondies to cool fully helps them set properly, making them easier to cut into squares without crumbling.
- Store Correctly: Keep leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for longer storage while maintaining their texture.
Best Side Dishes for Biscoff Blondies
Biscoff Blondies pair wonderfully with various sides that enhance their sweetness and flavors. Here are some great side dish ideas to enjoy alongside your blondies.
- Chocolate Mousse: A rich and creamy chocolate mousse complements the sweetness of the blondies beautifully.
- Fruit Salad: A refreshing mix of seasonal fruits adds brightness and balances the richness of your dessert.
- Cheese Platter: Include mild cheeses like brie or goat cheese; they provide an interesting contrast without overpowering the flavors.
- Coffee or Espresso: A cup of coffee enhances the spices in the blondies while providing a comforting beverage option.
- Pudding Parfait: Layer chocolate or vanilla pudding with crushed Biscoff cookies for an indulgent treat that echoes the flavors of your blondies.
- Nutty Granola: A sprinkle of homemade granola provides crunch and texture, adding another dimension to your dessert experience.
Common Mistakes to Avoid
When making Biscoff Blondies, it’s easy to overlook certain details that can affect the final result. Here are some common mistakes to avoid.
- Boldly skip the butter cooling step: Not allowing melted butter to cool can lead to scrambled eggs when mixed in. Always let it cool slightly before adding eggs.
- Boldly measuring flour incorrectly: Using too much flour can make your blondies tough. Spoon flour into the measuring cup and level it off for accuracy.
- Boldly ignoring pan preparation: Not lining your pan properly can make it difficult to remove the blondies. Use parchment paper with an overhang for easy lifting.
- Boldly underbaking: Pulling the blondies out too soon can result in a gooey center. Bake until edges are golden and a toothpick comes out with moist crumbs.
- Boldly neglecting cookie toppings: Skipping crushed Biscoff cookies on top means missing out on extra flavor and texture. Don’t forget this final touch!
