How to Make Biscoff Blondies
-
Preheat the oven to 350°F (180°C). Lightly grease an 8×8 inch pan and line it with baking paper, leaving some overhang for easy removal later.
-
Whisk together the melted butter, brown sugar, and granulated sugar in a large bowl until everything is well combined and smooth.
-
Add the egg, egg yolk, and vanilla extract, whisking until no pieces of egg remain visible. This creates a rich, cohesive mixture.
-
Mix in the flour and salt using a rubber spatula or wooden spoon; stir until just combined, ensuring not to overmix for those perfect chewy blondies.
-
Fold in the white chocolate chips and chopped speculoos cookies until evenly distributed throughout the batter.
-
Spread half of the batter into the bottom of the prepared pan. Warm the Biscoff cookie butter in the microwave for about 30 seconds and drizzle it over the batter.
-
Top with spoonfuls of the remaining batter, gently spreading it to mix slightly with the cookie butter, allowing for those delightful flavor swirls.
-
Bake in the center of your preheated oven for approximately 25-28 minutes, or until the top appears set and slightly golden around the edges.
-
Cool in the pan before lifting out using the parchment overhang. Slice into generous squares with a sharp knife for perfect portions.
Optional: Dust with powdered sugar before serving for an elegant touch.

Expert Tips for Making Biscoff Blondies
• Butter Temperature: Ensure that the butter is melted but not hot when combining with sugars. This prevents the sugars from crystallizing, leading to a better texture.
• Don’t Overmix: Mix just until combined when adding flour. Overmixing can create dense blondies instead of the light, chewy texture you desire.
• Swirl Technique: For a beautifully marbled effect, try not to spread the top layer of batter too evenly over the Biscoff spread. This allows for delightful pockets of flavor.
• Testing Doneness: Always use a toothpick to check for doneness. It should come out with a few moist crumbs attached; this ensures your Biscoff blondies remain soft and gooey.
• Cool Time: Allow the blondies to cool completely in the pan before slicing. This prevents them from falling apart and enhances flavor!
These helpful tips will ensure your Biscoff Blondies turn out perfectly delicious every time!
Make Ahead Options
These Biscoff Blondies are perfect for busy cooks who want to save time in the kitchen! You can prepare the blondie batter up to 24 hours in advance by mixing all the ingredients and storing it in an airtight container in the refrigerator. If you want to go a step further, you can bake the blondies ahead of time and let them cool completely. Then, wrap them tightly in plastic wrap and refrigerate for up to 3 days. When you’re ready to serve, simply slice the blondies and let them come to room temperature or warm them for a few seconds in the microwave. This way, they’ll be just as delicious, soft, and gooey as if you baked them fresh!

Biscoff Blondies Recipe FAQs
What is the best way to select ripe ingredients for Biscoff Blondies?
Absolutely! When it comes to choosing your ingredients, freshness is key. For the butter, use unsalted butter that is soft but not melted—this will help you achieve the perfect texture. For the eggs, select ones that are bright and clean, as freshness is essential. Lastly, make sure your Biscoff cookie butter is smooth and creamy for optimal results; a jar that has been opened for a while may have dried out edges, affecting the final flavor.
How should I store Biscoff Blondies, and how long do they last?
Very effective storage techniques will keep your blondies fresh! Store them in an airtight container at room temperature for up to 3 days. If you want to keep them longer, move them to the fridge, where they can last up to a week. Be sure to cover them tightly to prevent them from drying out. A simple trick I often use is to place a slice of bread in the container with the blondies; this helps to maintain moisture!
Can I freeze Biscoff Blondies, and what’s the best way to do it?
The more the merrier when it comes to freezing! Wrap each blondie individually in plastic wrap, then place them in a freezer-safe bag or container. They can be stored in the freezer for up to 2 months. When you’re ready to enjoy, thaw them at room temperature for a few hours or heat them gently in the microwave for about 10-15 seconds for that fresh-from-the-oven feel.
What should I do if my Biscoff Blondies turn out too dry or crumbly?
If your blondies happen to be on the dry side, don’t fret! The most common reason for dryness is overbaking. Keep an eye on them during the last few minutes of baking; they should be lightly golden on the edges but still soft in the middle. If they’ve already cooled and you notice they’re crumbly, you can try to serve them warm with a scoop of vanilla ice cream or drizzle them with more melted Biscoff spread to add some moisture back in.
Are these Biscoff Blondies safe for certain dietary restrictions or allergies?
Definitely worth checking! Since these blondies contain eggs, butter, and white chocolate, they are not suitable for vegans or those with dairy allergies. For a gluten-free version, you can substitute the all-purpose flour with a 1:1 gluten-free baking blend. Always make sure the specific brands you’re using, like the Biscoff products, meet your dietary needs—especially for allergies!
