Step‑by‑Step Instructions for Biscoff Blondies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, take a 9×9-inch baking pan and either grease it with a bit of butter or line it with parchment paper. This will ensure your Biscoff Blondies lift out easily and have a lovely, golden finish.
Step 2: Melt the Butters
In a medium saucepan over low heat, combine the unsalted butter and Biscoff cookie butter. Stir them together continuously until the mixture is smooth and fully melted, which should take about 3-5 minutes. Remove it from the heat and let it cool slightly so that the eggs don’t scramble when added.
Step 3: Add Brown Sugar
Once the mixture has cooled for about 5 minutes, whisk in the brown sugar until well incorporated. You want the batter to be smooth and glossy, signaling that the sugars are blending harmoniously with the butters. This step adds incredible depth and that rich caramel flavor to your Biscoff Blondies.
Step 4: Incorporate the Eggs
Crack in the eggs, adding them one at a time, and whisk thoroughly after each addition. Make sure to mix until the batter is fully blended and smooth, creating a thick and luscious mixture. This process helps bind the ingredients, giving your blondies their soft texture.
Step 5: Mix in Vanilla Extract
Add the vanilla extract to the batter, enhancing the overall flavor of your Biscoff Blondies. Stir gently until the extract is evenly distributed throughout the batter, ensuring that every bite carries that warm, inviting aroma.
Step 6: Prepare Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking powder, and salt. This will help aerate the flour and combine the dry ingredients evenly, adding to the light texture of your blondies.
Step 7: Combine Wet and Dry Ingredients
Gradually fold the sifted dry ingredients into the wet mixture. Do this gently until just combined, being careful not to overmix. This step is crucial for keeping your Biscoff Blondies chewy and soft, so stop mixing as soon as you no longer see dry flour bits.
Step 8: Add Mix-Ins
Now it’s time for the fun part! Gently fold in white chocolate chips and crushed Biscoff cookies. These delightful additions provide creamy bursts of sweetness and additional texture, making your Biscoff Blondies even more irresistible.
Step 9: Transfer to Baking Pan
Pour the batter into your prepared baking pan, spreading it evenly with a spatula. Make sure it’s nicely level to ensure even baking, which helps your blondies to cook uniformly and achieve that perfect chewy center.
Step 10: Bake to Perfection
Place the pan in the preheated oven and bake for 25-30 minutes. Start checking for doneness at the 25-minute mark by inserting a toothpick into the center. It should come out clean or with a few moist crumbs attached for that perfect blondie texture.
Step 11: Cool Before Slicing
Once baked, remove the Biscoff Blondies from the oven and let them cool in the pan for about 10 minutes. Afterward, carefully transfer them to a wire rack to cool completely. This ensures they maintain their wonderful texture and are easy to cut into squares.
Step 12: Slice and Serve
Cut your cooled blondies into squares and serve them as a delightful treat! These Biscoff Blondies are perfect to enjoy on their own or paired with a cup of coffee for a cozy touch.

Make Ahead Options
These Biscoff Blondies are perfect for busy home cooks looking to save time! You can prepare the batter up to 24 hours in advance; simply combine your wet and dry ingredients, ensuring not to overmix. After mixing, cover the bowl tightly with plastic wrap and refrigerate to maintain freshness. The crushed Biscoff cookies can also be measured out and stored in an airtight container for up to 3 days. When you’re ready to bake, just bring the batter to room temperature for about 30 minutes before pouring it into your prepared pan and baking. This way, you’ll enjoy freshly baked blondies while reducing your prep time for family gatherings or cozy nights in!
Storage Tips for Biscoff Blondies
Room Temperature: Store your Biscoff Blondies in an airtight container at room temperature for up to 3-4 days to keep them fresh and chewy.
Fridge: If you prefer a slightly firmer texture, you can refrigerate the blondies in an airtight container for up to a week. Allow them to come to room temperature before serving.
Freezer: For long-term storage, freeze the blondies by wrapping them individually in plastic wrap and placing them in a freezer-safe bag or container for up to 2-3 months.
Reheating: To enjoy a warm blondie, reheat in the microwave for 10-15 seconds until just warm, allowing those delicious Biscoff flavors to shine again!

Expert Tips for Biscoff Blondies
Cool Before Mixing: Allow the melted butter and cookie butter mixture to cool slightly before adding the eggs—this prevents them from scrambling and ensures a smooth texture.
Avoid Overmixing: Gently fold the dry ingredients into the wet mixture. Overmixing can lead to tough blondies instead of the soft, chewy Biscoff blondies we love.
Check for Doneness: Start checking your blondies at the 25-minute mark. The toothpick should come out clean or with a few moist crumbs for that perfect melt-in-your-mouth experience.
Texture Tips: For a chewy texture, let the blondies cool completely before slicing. This helps them set and hold their shape beautifully!

Biscoff Blondies Recipe FAQs
What’s the best way to select ripe ingredients for Biscoff Blondies?
Absolutely! Ensure your unsalted butter is at room temperature for easy mixing and that your Biscoff cookie butter is fresh—look for jars with no dark spots or separation, which may indicate it’s past its prime. Fresh eggs should also be used, ideally checked for the expiration date.
How should I store Biscoff Blondies for maximum freshness?
Store your Biscoff Blondies in an airtight container at room temperature for up to 3-4 days. They will retain that chewy texture you love! If you’re expecting to keep them longer, place them in the fridge for up to a week, or freeze them wrapped tightly in plastic wrap for up to 2-3 months.
Can I freeze Biscoff Blondies, and if so, how?
Very! To freeze your Biscoff Blondies, first allow them to cool completely. Then, cut them into squares and wrap each one individually in plastic wrap. Place the wrapped squares in a freezer-safe bag or container to protect them from freezer burn. When you’re ready to enjoy, just thaw them in the fridge overnight or pop them in the microwave for 10-15 seconds!
What should I do if my blondies turn out too dry?
If your blondies end up dry, it’s possible they were overbaked. Make sure to set a timer and start checking for doneness around the 25-minute mark. For future batches, consider adding a tablespoon of milk to the batter—this can help maintain moisture, making them even chewier.
Are Biscoff Blondies safe for people with allergies?
Biscoff Blondies contain common allergens such as eggs, gluten (from all-purpose flour), and dairy (from butter). If you’re baking for someone with allergies, I recommend swapping out these ingredients with suitable alternatives. There are egg replacers available, gluten-free flour options, or dairy-free butters that can work smoothly. Always check the labels for possible cross-contamination, and choose brands that meet the dietary needs.
Can I substitute any ingredients in the Biscoff Blondies?
Absolutely! If you’re running low on Biscoff cookie butter, you can use speculoos spread or a similar flavored nut butter for a different twist. For a nutty flavor, consider adding pecans or walnuts, or switch out the white chocolate chips for semi-sweet chocolate chips. The more the merrier when it comes to customizing these treats!
