Crafting the Perfect Biscoff Blondies: A Step-by-Step Guide

Creating these heavenly Biscoff Blondies is a straightforward and enjoyable process. Follow these detailed steps to ensure your blondies turn out perfectly thick, chewy, and bursting with flavor every time.

1. Prepare Your Rich Blondie Batter

The foundation of these incredible blondies begins with a decadent batter. Start by combining melted unsalted butter with the creamy cookie butter spread. Ensure your butter is just melted, not hot, to prevent scrambling the eggs later. Next, add both granulated sugar and packed brown sugar. The melted butter contributes to the rich, fudgy consistency, while the brown sugar adds a deep molasses flavor and helps achieve that signature chewy texture. Whisk these wet ingredients thoroughly until they are well combined and smooth, creating a luscious base. Incorporate the large eggs, preferably at room temperature for better emulsion, and a generous splash of vanilla extract for warmth and depth of flavor. Mix for about 30 seconds until everything is fully incorporated. Finally, gently fold in the dry ingredients – all-purpose flour, baking powder for lift, a touch of salt to balance the sweetness, and a hint of cinnamon to enhance the Biscoff spice. Mix just until a few streaks of flour remain; overmixing can lead to tough blondies. The grand finale is folding in the white chocolate chips, which add delightful pockets of sweet creaminess.

2. Transfer Batter to the Baking Pan with Ease

Once your irresistible blondie batter is ready, it’s time to prepare it for baking. Line a 9”x9” metal baking pan with parchment paper. A useful trick is to create a “sling” with the parchment paper, allowing it to overhang on all four sides of the pan. This ingenious method makes lifting the entire batch of baked blondies out of the pan incredibly easy once cooled, preventing any sticking and ensuring perfect squares. Carefully pour the thick batter into the prepared pan. Use an offset spatula or the back of a spoon to gently and evenly spread the batter across the bottom of the pan, ensuring it reaches all corners for uniform thickness and consistent baking.

3. Enhance with Crunchy Biscoff Cookie Topping

To elevate both the flavor and visual appeal of your blondies, generously top them with crushed Biscoff cookies. Take 6-8 Biscoff cookies and gently crush them into various-sized pieces – some larger crumbs, some finer. Sprinkle these crushed pieces evenly over the surface of the blondie batter in the pan. Lightly press them into the batter with your fingertips or the back of a spoon. This not only adds a wonderful textural contrast with every bite but also beautifully showcases the distinctive Biscoff flavor, hinting at the deliciousness within before anyone even takes a taste. This step is key for that extra layer of caramelized spice and satisfying crunch.

4. Bake to Golden Perfection

Your Biscoff Blondies are now ready for the oven! Preheat your oven to 350°F (175°C). Place the prepared pan into the preheated oven and bake for approximately 30-35 minutes. Baking time can vary slightly depending on your oven, so it’s important to keep an eye on them. The key to perfect blondies is to avoid overbaking. You want the edges to be golden brown and set, while the center remains slightly soft and gooey, with a delightful fudgy texture. To test for doneness, insert a toothpick into the middle of the blondies. It should come out with a few moist crumbs clinging to it, not wet batter, but also not completely clean. If the toothpick comes out completely clean, they might be slightly overbaked, leading to a drier texture. Once baked, remove the pan from the oven and let the blondies cool completely in the pan before attempting to cut them. This allows them to set properly and enhances their chewy texture.

5. A Final Drizzle of Cookie Butter Bliss

After your blondies have had a chance to cool down, it’s time for the ultimate finishing touch: a decadent drizzle of melted cookie butter spread. Gently melt 2 tablespoons of Biscoff cookie butter spread in the microwave for a few seconds or in a small saucepan over low heat until it’s pourable. Using a spoon, drizzle the warm, melted cookie butter artfully over the entire surface of the cooled blondies. This not only adds an extra burst of Biscoff flavor but also creates a beautiful, glossy finish that makes them even more appealing. Once the drizzle has set slightly, lift the blondies out of the pan using the parchment paper sling. Place them on a cutting board, slice them into 16 equal squares, and serve. Get ready to enjoy these wonderfully rich, spiced, and chewy treats!

Your Top Biscoff Blondie Questions Answered (FAQs)

Here are some frequently asked questions about Biscoff Blondies to help you master this delicious recipe and enjoy your baking experience even more.

What Exactly is Biscoff?

Biscoff refers to a popular brand of speculoos cookies, which are distinctively spiced, caramelized, and crunchy biscuits. Originating from Belgium, these cookies have gained worldwide recognition for their unique flavor profile. “Biscoff” is also the name given to the incredibly creamy spread made from these very cookies. Lotus Biscoff is the most well-known brand, but you might find similar products like Trader Joe’s Speculoos Cookie Butter. These spreads share a similar texture to peanut butter but offer a completely different taste—a warm, comforting blend of cinnamon, nutmeg, and other spices, with a pronounced caramelized sugar note. This unique flavor makes cookie butter an exceptional ingredient for desserts, as seen in these blondies and other treats like my Mini Biscoff Cheesecakes.

What’s the Best Way to Store My Biscoff Blondies?

To maintain their optimal freshness, softness, and chewiness, store your cooled Biscoff Blondies in an airtight container or a zip-top bag. Keep them at room temperature, away from direct sunlight or heat, for up to 3 days. If you live in a particularly warm or humid climate, or if you prefer a firmer texture, you can store them in the refrigerator for up to a week. Just be aware that refrigeration might make them slightly firmer, so bringing them back to room temperature before serving will enhance their fudgy consistency.

Can I Freeze Biscoff Blondies?

Absolutely, Biscoff Blondies freeze exceptionally well! Freezing is a fantastic option if you’ve baked a large batch or want to prepare them in advance. To freeze, ensure the blondies are completely cooled. Once cooled, place them in a single layer in a freezer-safe zip-top bag or an airtight container, separating layers with parchment paper if stacking. They can be stored in the freezer for up to 2-3 months without losing their quality. When you’re ready to enjoy them, simply pull them out of the freezer the night before or several hours before serving and let them thaw at room temperature. This gradual thawing helps them retain their delicious texture.

What Size Baking Pan is Ideal for This Recipe?

For this specific Biscoff Blondie recipe, I highly recommend using a 9”x9” square metal baking pan. A metal pan is preferred because it conducts heat more efficiently and evenly than glass or ceramic pans, resulting in blondies that bake consistently and achieve that desirable golden-brown edge. While you could use an 8”x8” pan, be aware that your blondies will be noticeably thicker and will require additional baking time to cook through properly. If you opt for an 8”x8” pan, start checking for doneness a few minutes earlier than the recommended time, and be prepared to extend baking by 5-10 minutes or more. Always adjust baking time based on the visual cues and toothpick test.

How Do I Know When My Blondies Are Perfectly Baked?

Knowing exactly when your blondies are done is crucial for achieving that signature chewy, slightly gooey texture. The blondies should have golden-brown edges that appear set and firm. The center, however, should still look slightly soft and might jiggle just a tiny bit when gently shaken. Resist the urge to overbake them, as this will lead to dry, crumbly blondies instead of the moist, fudgy ones we’re aiming for. The most reliable test is to insert a toothpick into the very center of the pan. It should come out with a few moist crumbs attached—not wet, raw batter, but definitely not completely clean. A completely clean toothpick indicates they’ve baked too long. Trust your instincts and these visual cues to pull them out at the perfect moment!

Pro Baking Tip: Precision with a Kitchen Scale!

For truly consistent and superior baking results, I cannot stress enough the importance of using a kitchen scale to weigh your ingredients. While measuring cups are convenient, they can lead to inconsistencies due to varying packing techniques for ingredients like flour or brown sugar. A kitchen scale, on the other hand, provides exact measurements in grams, ensuring that your recipe turns out perfectly every single time. This precision leads to a better success rate with your baking and eliminates guesswork. As an added bonus, weighing ingredients directly into your mixing bowl reduces the number of dishes you’ll need to wash, making cleanup a breeze! I provide gram measurements in all my recipes to encourage this best practice, and this is the scale I personally love and recommend.

SHOP INGREDIENTS

Instructions

 

  • Preheat your oven to 350°F (175°C). Lightly grease a 9” x 9” square metal baking pan with cooking spray. Line the pan with parchment paper, allowing it to overhang on all four sides to create a “sling.” This will make it much easier to lift the baked blondies out later.
  • In a large mixing bowl, combine the slightly cooled melted butter with the Biscoff cookie butter spread, packed light brown sugar, and granulated sugar. Whisk these ingredients vigorously until they are thoroughly combined and smooth, creating a uniform mixture.
  • Add the two large, room-temperature eggs one at a time, mixing well after each addition, then stir in the vanilla extract. Continue mixing for about 30 seconds until the mixture is fully emulsified. In a separate bowl, whisk together the all-purpose flour, baking powder, salt, and cinnamon. Gradually add the dry ingredients to the wet ingredients, mixing with a spatula until just a few streaks of flour remain. Be careful not to overmix. Gently fold in the white chocolate chips.
  • Pour the prepared batter into the parchment-lined baking pan. Use an offset spatula or the back of a spoon to spread the batter evenly across the pan. Sprinkle the crushed Biscoff cookie pieces generously over the top of the batter, pressing them lightly into the surface. Bake for 30-35 minutes, or until the edges are golden brown and set, and the center still appears slightly soft but no longer wet. A toothpick inserted into the center should come out with moist crumbs, not liquid batter.
  • Once baked, remove the blondies from the oven and allow them to cool completely in the pan on a wire rack. While they cool, melt the remaining 2 tablespoons of Biscoff cookie butter spread. Once the blondies are fully cooled, drizzle the melted cookie butter over the top for an extra layer of flavor and a beautiful finish. Lift the blondies from the pan using the parchment paper sling, cut them into 16 equal squares, then serve and enjoy!
