Biscoff Blondie Ingredients
For the Batter
• Unsalted Butter – Adds moisture and richness. Substitution: Use salted butter and reduce additional salt in the recipe.
• Biscoff Cookie Butter – Provides the signature flavor and sweetness. Substitution: Alternative speculoos spread or nut butters may be used, but expect a flavor change.
• Brown Sugar – Contributes moisture and caramel notes. No substitutions necessary, but using white sugar will change the texture.
• Large Eggs – Binds ingredients and provides structure. No substitutions suggested.
• Vanilla Extract – Enhances overall flavor. Consider using homemade for a richer taste.
• All-Purpose Flour – Forms the base of the blondies. Substitution: For a gluten-free option, a 1:1 gluten-free baking blend could work.
• Baking Powder – Leavening agent for lift. Ensure it’s fresh for best results.
• Salt – Balances sweetness and enhances flavors. Omit if using salted butter.
For the Mix-ins
• White Chocolate Chips – Add sweetness and creaminess. Substitution: Use milk or dark chocolate chips if preferred.
• Crushed Biscoff Cookies – Adds texture and extra flavor. Substitution: Other cookie crumbs may work but won’t replicate the Biscoff taste.
Step‑by‑Step Instructions for Biscoff Blondies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms up, line a 9×9-inch baking pan with parchment paper, allowing some overhang for easy removal later. This simple preparation sets the stage for your Biscoff Blondies to bake evenly and become a delightful treat.
Step 2: Melt the Butters
In a medium saucepan over low heat, combine the unsalted butter and Biscoff cookie butter. Stir gently until both are fully melted and combined, creating a smooth, creamy mixture. This should take around 3-5 minutes, allowing those warm, inviting scents to fill your kitchen—anticipation is part of the fun!
Step 3: Mix in Sugar
Once melted, remove the saucepan from heat and let it cool for about 5 minutes. Afterward, add the brown sugar, stirring vigorously until the mixture is smooth and glossy. This step ensures that your Biscoff Blondies will be sweet and rich, capturing the essence of that deep caramel flavor.
Step 4: Incorporate Eggs and Vanilla
Next, whisk in the large eggs one at a time, ensuring each is fully incorporated before adding the next. Follow this by pouring in the vanilla extract. Continue mixing until the batter is well blended and glossy, letting the warmth of the ingredients enhance the delicious aroma filling your kitchen.
Step 5: Combine Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking powder, and salt. This step is crucial for evenly distributing the leavening agent, ensuring your Biscoff Blondies rise beautifully. The combination of dry ingredients adds structure, giving your dessert the perfect chewy texture.
Step 6: Mix Wet and Dry Ingredients
Gradually add the dry mixture to your wet ingredients, folding gently until just combined. Be careful not to overmix; you want your blondies to remain soft and tender. The batter will be thick, and the enticing aroma of Biscoff will begin to fill the air, creating a welcoming atmosphere.
Step 7: Fold in Mix-ins
Now it’s time to add the white chocolate chips and crushed Biscoff cookies. Gently fold these delightful ingredients into the batter, ensuring they’re evenly distributed. This will add bursts of creamy sweetness and crispy texture to your blondies, elevating them to an indulgent treat!
Step 8: Bake the Blondies
Pour the batter into your prepared baking pan, spreading it evenly with a spatula. Place the pan in the preheated oven and bake for 25-30 minutes. Keep an eye on them; the edges should be slightly golden, and the center will be set yet still moist, creating that perfect chewy consistency.
Step 9: Check for Doneness
Once the time is up, perform the toothpick test by inserting it into the center of the blondies. If it comes out with a few moist crumbs, they’re ready. If the toothpick shows wet batter, return them to the oven and check again after a couple of minutes.
Step 10: Cool and Slice
Once baked to perfection, allow the blondies to cool in the pan for about 10 minutes. Then, carefully transfer them to a wire rack using the parchment overhang. Let them cool completely before slicing into squares. Your Biscoff Blondies are now ready to be savored—you’ve created a delightful treat that’s sure to impress!

How to Store and Freeze Biscoff Blondies
Room Temperature: Keep your freshly baked Biscoff Blondies in an airtight container at room temperature for up to 3 days to maintain their soft, chewy texture.
Fridge: If you prefer, you can refrigerate the blondies, which will extend their freshness up to a week. Just make sure they’re covered to prevent drying out.
Freezer: For longer storage, individually wrap the blondies in plastic wrap and place them in a freezer-safe bag. They can last in the freezer for 2-3 months without losing flavor.
Reheating: To enjoy them warm, simply pop the blondies in the microwave for about 10-15 seconds! They’ll regain that gooey deliciousness, making them taste freshly baked.
Expert Tips for Biscoff Blondies
Melt Slowly: Ensure you melt the butter and Biscoff cookie butter together gently to prevent separation and achieve a smooth consistency.
Avoid Overmixing: Mix the batter until just combined. Overmixing can result in tough blondies instead of the desired soft, chewy texture.
Toothpick Test: Check the doneness of your Biscoff Blondies with a toothpick—aim for a few moist crumbs rather than a clean stick to keep them moist.
Pan Prep: Using parchment paper with overhang in your baking pan makes it easy to lift the blondies out and cut them into neat squares.
Cool Completely: Allow the blondies to cool completely before slicing. This helps them set and enhances the flavors, making each bite even more enjoyable.

Biscoff Blondies Recipe FAQs
What type of Biscoff cookie butter should I use?
Absolutely! For the best flavor, I recommend using a smooth, creamy Biscoff cookie butter. This will infuse your blondies with that signature spiced caramel taste. While you can substitute other speculoos spreads or nut butters, keep in mind that the flavor will differ; Biscoff has a unique taste that truly shines in this recipe.
How long do Biscoff blondies last?
Biscoff Blondies can be stored at room temperature in an airtight container for up to 3 days. For longer freshness, you can refrigerate them, and they’ll stay good for up to a week! Just be sure they’re well-covered to prevent them from drying out.
Can I freeze Biscoff blondies?
Yes, you can absolutely freeze Biscoff Blondies! Individually wrap each blondie in plastic wrap and place them in a freezer-safe bag. They can be stored in the freezer for 2-3 months. When you’re ready to indulge, simply thaw them in the fridge and warm them in the microwave for about 10-15 seconds for that freshly baked taste.
What should I do if my blondies are too dense or dry?
Very! If your blondies turn out too dense, it could be due to overmixing the batter or using too much flour. To avoid this, mix the wet and dry ingredients just until combined. As for dryness, make sure to bake them until they’re just set; a toothpick inserted in the center should come out with a few moist crumbs. If they ever dry out, serving them with a scoop of ice cream can help moisture levels!
Are Biscoff blondies suitable for those with nut allergies?
If you want to make these Biscoff Blondies nut-free, you can! Just ensure that your cookie butter doesn’t contain any nuts. For those with severe allergies, I recommend reviewing all package ingredients, as safety is key. You might also consider experimenting with seed butters as a substitute for typical nut butters if a variation is desired!
Can I make Biscoff blondies gluten-free?
Absolutely! To make these delicious Biscoff Blondies gluten-free, you can replace the all-purpose flour with a 1:1 gluten-free baking blend. Just be sure that your other ingredients, such as the cookie butter and baking powder, are also gluten-free to maintain that perfect chewy texture!
