Ingredients You’ll Need
Gathering simple ingredients is the best part because each one plays a starring role in creating the incredible flavor and texture of these blondies. Everything from the creamy butter to the crunchy cookie crumbles works together to build this treat’s irresistible character.

- Large eggs: Bind the ingredients together and help with the structure while adding a slight richness.
- Vanilla extract: Enhances all the sweet flavors with a subtle aromatic note.
- All-purpose flour: The main dry ingredient that builds the blondie’s tender crumb.
- Baking powder: Provides just enough lift to keep them from being too dense.

How to Make Biscoff Blondies Recipe
Step 1: Prepare Your Baking Pan
Start by heating your oven to 350°F (175°C) and get your 9×9-inch baking pan ready. Greasing it or lining with parchment paper ensures your blondies will release effortlessly after baking — no sticking frustrations here.
Step 2: Melt the Butters Together
In a medium saucepan over low heat, melt the unsalted butter and the luscious Biscoff cookie butter while stirring occasionally. This melting process creates a smooth, irresistibly fragrant base that’s crucial for your blondies’ rich flavor.
Step 3: Let the Mixture Cool
Once melted together, remove the pan from heat and let it cool slightly for about five minutes. This step helps when you add eggs next—preventing them from scrambling and ensuring a silky batter.
Step 4: Mix in the Brown Sugar
Add the brown sugar directly to your warm butter mixture and whisk until everything is smoothly combined. This blend is where those deep caramel notes really start to shine through.
Step 5: Incorporate the Eggs
Whisk in the eggs one by one, making sure each is fully mixed in before adding the next. This brings everything together and adds the moisture needed to create that soft, chewy consistency.
Step 6: Stir in Vanilla Extract
Vanilla is your flavor booster here — pour it in and mix thoroughly to spread that lovely aroma evenly throughout your batter.
Step 7: Combine the Dry Ingredients
In a separate large bowl, sift the flour, baking powder, and salt. Sifting not only avoids lumps but also helps achieve the perfect lightness in the final blondies.
Step 8: Bring Wet and Dry Together
Gradually add your sifted dry ingredients to the wet mixture, folding gently with a spatula or wooden spoon. Avoid overmixing to keep the blondies tender rather than dense or tough.
Step 9: Fold in the White Chocolate and Crushed Cookies
This is the fun part! Gently fold in the white chocolate chips and crushed Biscoff cookies. These add texture and those delightful pockets of rich flavor and crunch.
Step 10: Bake to Perfection
Pour the batter into your prepared pan and spread it out evenly. Pop it in the preheated oven and bake for 25 to 30 minutes. Keep an eye on it, and use a toothpick inserted in the center — when it comes out clean or with few crumbs, you know it’s ready!
Step 11: Cool Before Cutting
Let the blondies cool in the pan on a wire rack for about 10 minutes, then remove them to cool completely before slicing. This ensures clean cuts and that perfect chewy texture you crave.
How to Serve Biscoff Blondies Recipe

Garnishes
Add a simple dusting of powdered sugar or a drizzle of melted white chocolate for an elegant finish. For an indulgent twist, top with a dollop of whipped cream or a scoop of vanilla ice cream — pure bliss.
Side Dishes
Pair these blondies with a cup of hot coffee or tea for a cozy treat. They also complement fresh fruit or a tangy yogurt parfait to balance out the sweetness in a delightful way.
Creative Ways to Present
Serve the blondies in bite-sized cubes on a decorative platter for parties or afternoon teas. Or layer them with whipped cream and fruit in a trifle for a stunning dessert centerpiece that will wow your guests.
Make Ahead and Storage
Storing Leftovers
Keep your leftover Biscoff blondies in an airtight container at room temperature for up to four days. This keeps them moist and chewy, ready whenever you need a quick pick-me-up.
Freezing
If you want to stash some for later, these blondies freeze wonderfully. Wrap them tightly in plastic wrap and then place in a freezer-safe container or bag. They can be frozen for up to three months without losing flavor or texture.
Reheating
To enjoy frozen blondies, thaw them at room temperature and warm gently in a microwave for about 15 to 20 seconds if you desire that just-baked warmth. Be careful not to overheat to preserve texture and taste.
FAQs
Can I substitute the Biscoff cookie butter with something else?
While Biscoff cookie butter is the heart of this recipe, you can experiment with other nut butters like peanut or almond butter, though the signature caramel-spice flavor will be missing.
What if I don’t have white chocolate chips?
You can use regular chocolate chips, but white chocolate pairs beautifully with the Biscoff flavors. Alternatively, chunks of your favorite chocolate bar can add a nice touch too.
How do I know when the blondies are done baking?
Insert a toothpick into the thickest spot; it should come out clean or with just a few moist crumbs. Keep watch during the last few minutes to avoid overbaking which can dry them out.
Can I make these blondies gluten-free?
Absolutely! Substitute the all-purpose flour with a 1-to-1 gluten-free flour blend, ensuring it contains xanthan gum for structure, and you’ll have delicious gluten-free Biscoff blondies.
What’s the best way to cut the blondies neatly?
Make sure the blondies are completely cool before slicing. Use a sharp knife, and for cleaner cuts, wipe the blade between slices or even warm the knife slightly.
