Now that you have your Biscoff Blondies Chewy Cookie Butter Dessert Bars ingredients ready, let’s move on to the fun part—baking!
Step‑by‑Step Instructions for Biscoff Blondies Chewy Cookie Butter Dessert Bars
Step 1: Preheat the Oven and Prepare the Pan
First, preheat your oven to 350°F (175°C). While it warms up, grab a 9x13 inch baking pan. Grease it lightly or line it with parchment paper, ensuring to leave some overhang. This will allow for an easy lift-out once your delightful Biscoff Blondies are baked!
Step 2: Mix the Sugars and Butter
In a large mixing bowl, combine 1 cup of melted unsalted butter, 1 cup of packed brown sugar, and ½ cup of granulated sugar. With a whisk, mix these ingredients together until the mixture is smooth and creamy, about 2 minutes. The sugar should be well incorporated, giving a glossy appearance.
Step 3: Add Eggs and Vanilla
Next, crack in 2 large eggs one at a time, whisking thoroughly after each addition until fully incorporated. This process should take about 1 minute per egg. After the eggs are combined, stir in 1 tablespoon of vanilla extract, infusing a warm aroma into your batter.
Step 4: Whisk the Dry Ingredients
In a separate bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking powder, ½ teaspoon of baking soda, and ¼ teaspoon of salt. This step is crucial for ensuring an even rise and perfect texture in your Biscoff Blondies, so make sure to mix until no lumps remain.
Step 5: Combine Wet and Dry Ingredients
Gradually add the dry mixture into the wet ingredients using a spatula or wooden spoon. Mix gently until no dry flour is visible; take care not to overmix, as this can affect the texture of your blondies. The batter should be thick and just combined—this means you're ready for the next step!
Step 6: Incorporate Biscoff Cookie Butter
Now it's time to introduce the star of the show: 1 cup of Biscoff cookie butter. Gently fold it into the batter until it's smooth, allowing for some swirls to remain for a beautiful marbled effect. This will elevate the flavors of your chewy cookie butter dessert bars.
Step 7: Fold in Crushed Biscoff Cookies
Next, fold in ½ cup of crushed Biscoff cookies, keeping a handful aside for topping. This adds a delightful crunch and texture. Make sure the crushed cookies are evenly distributed throughout the batter, enhancing every bite of your Biscoff Blondies Chewy Cookie Butter Dessert Bars.
Step 8: Pour and Spread the Batter
Pour the prepared batter into the greased or lined baking pan, using a spatula to spread it evenly into the corners. Sprinkle the reserved crushed Biscoff cookies over the top for added crunch and a charming presentation. Your dessert is almost ready to bake!
Step 9: Bake to Perfection
Place the pan in your preheated oven and bake for 25-30 minutes. Keep an eye on them; they’re done when a toothpick inserted in the center comes out mostly clean with a few moist crumbs. Avoid overbaking to maintain that chewy, delicious texture of your blondies.
Step 10: Add Sea Salt
Once your Biscoff Blondies are baked to golden perfection, remove them from the oven. While they are still warm, sprinkle a pinch of sea salt over the top. This final touch enhances the flavors, balancing the sweetness beautifully.
Step 11: Cool and Cut into Squares
Allow your blondies to cool in the pan for about 15 minutes. Then, using the parchment paper overhang, lift them out and transfer to a wire rack. Let them cool completely before cutting them into squares. This ensures the bars hold their shape, perfect for savoring!

Make Ahead Options
These Biscoff Blondies Chewy Cookie Butter Dessert Bars are perfect for those busy weeknights when you need a tasty treat without the last-minute stress! You can prepare the blondie batter up to 24 hours in advance; simply mix everything together and store it in an airtight container in the refrigerator. To maintain the chewy texture, let the batter come to room temperature for about 30 minutes before pouring it into the baking dish and baking. If you prefer to freeze them, bake the blondies completely, let them cool, and then cut them into squares. Wrap each one tightly and store in the freezer for up to 3 months. When ready to enjoy, simply thaw at room temperature for a few hours or warm them slightly in the oven for that just-baked flavor, ensuring delightful, restaurant-quality results with minimal effort!
How to Store and Freeze Biscoff Blondies
Room Temperature: Store cooled blondies in an airtight container at room temperature for up to 3 days. This keeps them fresh and chewy for indulging anytime!
Fridge: For longer storage, place the blondies in an airtight container in the fridge, where they can last up to a week. Just remember to bring them to room temperature before serving!
Freezer: To freeze, wrap individual blondie squares tightly in plastic wrap or foil before placing them in a freezer bag. They can be frozen for up to 3 months and thaw in the fridge or at room temperature.
Reheating: To enjoy your Biscoff Blondies warm, preheat the oven to 350°F (175°C) and bake for about 5-7 minutes or microwave for 10-15 seconds until warm.
Expert Tips for Biscoff Blondies
Mixing Temperatures Matter: Ensure your butter is melted but not too hot when mixing, as this can cook the eggs and create a scrambled texture in the batter.
Don’t Overmix: When combining wet and dry ingredients, mix just until combined. Overmixing can lead to tough blondies instead of the desired chewy texture.
Perfect Bake Time: Keep an eye on the baking time; toothpicks should come out with a few moist crumbs for chewy Biscoff Blondies. Overbaking results in a cake-like texture.
Allow Proper Cooling: Let the blondies cool thoroughly before cutting. This helps them set and achieve that perfect chewy consistency everyone loves.
Sea Salt Sprinkle: Don’t skip the sea salt on top after baking! It enhances the rich flavors and provides a delightful contrast to the sweetness.
Store Them Right: Keep your leftovers in an airtight container at room temperature for up to 3 days to maintain freshness and chewiness.
