Step‑by‑Step Instructions for Irresistibly Chewy Biscoff Blondies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While that’s warming up, grease or line a 9×9-inch baking pan with parchment paper, ensuring it hangs over the edges slightly for easy removal later. This simple step will ensure your Biscoff Blondies bake perfectly and slide out effortlessly.
Step 2: Melt the Butters
In a medium saucepan over low heat, melt the unsalted butter alongside the Biscoff cookie butter, stirring continuously until you achieve a smooth, creamy mixture. This should take about 5-7 minutes; watch carefully to prevent the butters from burning. Once melted, remove the saucepan from heat and let it cool for a few minutes.
Step 3: Combine with Sugar
Next, whisk in the brown sugar into the warm butter mixture until it’s well blended. You want everything mixed together without any lumps, which should take about 1-2 minutes. The warm mixture will help dissolve the sugar, creating a nice glossy base for your Biscoff Blondies.
Step 4: Incorporate Eggs and Vanilla
Once the sugar is fully combined, add the eggs one at a time, whisking vigorously after each addition until the mixture is smooth and glossy. Then stir in the vanilla extract, allowing it to mix well. This will enrich the blondie batter and enhance the flavors of your Irresistibly Chewy Biscoff Blondies.
Step 5: Mix the Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking powder, and salt. This step is crucial for aerating your dry ingredients, helping the blondies rise nicely. Gently fold the dry mixture into the wet ingredients until just combined, being careful not to overmix, as this can affect the final texture.
Step 6: Add Sweet Additions
Now, gently fold in the white chocolate chips and crushed Biscoff cookies, ensuring an even distribution throughout the batter. You want those delightful pockets of sweetness and crunch in each bite of your blondies. Be careful during this step to maintain the light and chewy texture of your Biscoff Blondies.
Step 7: Bake the Blondies
Pour the batter into your prepared baking pan and use a spatula to spread it evenly. Bake in your preheated oven for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs. Keep an eye on the blondies to avoid overbaking.
Step 8: Cool and Slice
Once baked, remove the pan from the oven and let the blondies cool in the pan for about 10 minutes. After cooling slightly, lift them out using the parchment paper and transfer to a wire rack to cool completely. Once fully cooled, cut into squares and enjoy the delicious flavors of your homemade Biscoff Blondies!

Expert Tips for Biscoff Blondies
-
Melt Gently: Always melt the butters over low heat to prevent burning, ensuring a smooth blend without any burnt flavor.
-
Don’t Overmix: Fold the dry ingredients gently into the wet mixture; overmixing can lead to tough blondies instead of the chewy texture you’re aiming for.
-
Cool Completely: Allow the blondies to cool entirely before slicing to achieve clean edges; slicing too soon can lead to crumbly pieces.
-
Check for Doneness: Use a toothpick to check doneness; it should come out with a few moist crumbs, not clean, to ensure the perfect chewy bite.
-
Customize with Care: If adding nuts or mix-ins, keep in mind that too many will throw off the balance of flavors and textures in your Biscoff Blondies.
Storage Tips for Biscoff Blondies
Room Temperature: Store your Biscoff Blondies in an airtight container at room temperature for up to 3-4 days. This keeps them moist and ready to enjoy!
Fridge: If you prefer, you can also store them in the fridge for a slightly firmer texture, lasting up to a week. Just be sure to cover them tightly to prevent drying out.
Freezer: For longer storage, freeze the blondies in an airtight container or tightly wrapped in plastic wrap for up to 2-3 months. Thaw in the fridge overnight when you’re ready to enjoy again.
Reheating: To bring them back to life, warm in the microwave for 10-15 seconds or in the oven at 350°F (175°C) for a few minutes, ensuring they’re warmed through and delightfully chewy.

Biscoff Blondies Recipe FAQs
How do I select ripe Biscoff cookies for the best flavor?
Absolutely! Fresh Biscoff cookies should be crunchy and fragrant, with a golden-brown hue. Check for any dark spots or packaging damage, as this can impact the flavor and texture. Choosing cookies close to their best-by date is fine; they still hold their taste if stored correctly.
What is the best way to store leftover Biscoff Blondies?
Very good question! Store your Biscoff Blondies in an airtight container at room temperature for up to 3-4 days. This keeps them deliciously moist. For longer-term storage, you can pop them in the fridge for up to a week, but remember to cover them well to prevent drying.
Can I freeze Biscoff Blondies, and if so, how should I do it?
Yes, you can! To freeze, wrap each blondie tightly in plastic wrap or place them in an airtight container. They’ll keep well for up to 2-3 months. When you’re ready to enjoy them, thaw the blondies in the fridge overnight. If you’re in a hurry, a quick 10-15 seconds in the microwave will do wonders, bringing back that fresh-baked taste!
What should I do if my Biscoff Blondies turn out too dry?
If your blondies come out a bit dry, don’t despair! You might have overbaked them. Next time, check for doneness with a toothpick at around 25 minutes. If it comes out with just a few moist crumbs, they’re perfect! To add moisture back, consider reheating them with a scoop of ice cream or a drizzle of warm caramel sauce to enhance that chewy texture.
Are these Biscoff Blondies safe for pets/allergies?
While Biscoff Blondies are a delight for humans, they aren’t suitable for pets, especially dogs, due to the sugar and certain ingredients like chocolate. Each blondie contains eggs and gluten (from flour), so if there are allergies in your household, you might want to modify ingredients, opting for gluten-free flour or egg substitutes to cater to dietary needs. Always check with family members about any allergies beforehand!
