Ingredients You’ll Need
Gathering simple yet flavorful ingredients is the first step to creating these luscious blondies. Each component plays a crucial role in building the perfect balance of sweetness, texture, and color that defines the Biscoff Blondies Recipe.
- Unsalted butter: Adds richness and moisture while allowing control over the saltiness in the blondies.
- Biscoff cookie butter: Infuses the blondies with that signature spiced caramel flavor everyone loves.
- Brown sugar: Brings deep, molasses-like sweetness that keeps the blondies chewy and moist.
- Large eggs: Help bind everything together, providing structure without weighing down the batter.
- Vanilla extract: Enhances all the flavors with its warm, aromatic notes.
- All-purpose flour: The foundation that creates the tender crumb of the blondies.
- Baking powder: Gives a light lift so the blondies aren’t dense or heavy.
- Salt: Balances the sweetness and elevates the Biscoff flavor even further.
- White chocolate chips: Melt into gooey pockets of creamy sweetness throughout.
- Crushed Biscoff cookies: Add delightful crunch and reinforce that iconic spiced taste.
How to Make Biscoff Blondies Recipe
Step 1: Prepare Your Baking Pan and Oven
Start by preheating your oven to 350°F (175°C) and greasing a 9×9-inch square pan, or line it with parchment paper. This prep ensures your blondies release easily and bake evenly so you can enjoy a perfect batch without any fuss.
Step 2: Melt the Butter and Biscoff Cookie Butter
In a medium saucepan, melt together the unsalted butter and Biscoff cookie butter over low heat, stirring occasionally. Combining these two rich butters creates the luscious base flavor that distinguishes this blondie recipe and guarantees a tender crumb.
Step 3: Cool the Butter Mixture Slightly
Once melted, remove the pan from heat and let the mixture cool for about 5 minutes. Cooling prevents the eggs from scrambling when added and helps maintain a smooth texture in your batter.
Step 4: Incorporate the Brown Sugar
Add the brown sugar to the warm butter mixture and whisk until it’s fully incorporated and smooth. This action blends sweetness and moisture beautifully, setting the stage for the rich blondie flavor.
Step 5: Add the Eggs
Crack the eggs into the butter and sugar mixture and whisk thoroughly until totally combined. The eggs are key to binding your ingredients and giving the blondies their perfect chewy consistency.
Step 6: Stir in Vanilla Extract
Pour in the vanilla extract and stir to ensure the warmth of the vanilla complements the caramel notes from the Biscoff cookie butter, adding depth to your blondies.
Step 7: Sift Dry Ingredients Separately
In a large bowl, sift together the flour, baking powder, and salt. Sifting helps lighten the dry ingredients, preventing lumps and promoting an even texture in the final bake.
Step 8: Combine Wet and Dry Ingredients Gently
Slowly fold the dry ingredients into the wet ingredients using a spatula or wooden spoon. Mixing gently is crucial here to avoid overworking the batter, which could make your blondies dense rather than tender and cakey.
Step 9: Fold in White Chocolate Chips and Crushed Cookies
Gently stir in the white chocolate chips and crushed Biscoff cookies until evenly spread throughout the batter. These add lovely pockets of sweet creaminess and crunch, making every bite exciting.
Step 10: Spread Batter in Prepared Pan
Pour your batter into the baking pan and spread it evenly using a spatula, making sure it reaches every corner for consistent baking and texture across the entire pan.
Step 11: Bake Until Just Done
Pop the pan into your preheated oven and bake for 25 to 30 minutes. Use a toothpick inserted in the center to check doneness; it should come out clean or with just a few moist crumbs to ensure the blondies stay soft and chewy.
Step 12: Cool Before Cutting
Let the blondies cool in the pan on a wire rack for 10 minutes, then lift them out using the parchment paper if used, and allow them to cool completely before slicing. This resting time helps set their texture for neat, clean cuts.
How to Serve Biscoff Blondies Recipe

Garnishes
A simple dusting of powdered sugar or a drizzle of melted white chocolate can elevate your blondies to dessert-table royalty. Adding a few whole Biscoff cookies on top before serving also amps up visual appeal and adds extra crunch.
Side Dishes
Serve these blondies with a scoop of vanilla ice cream or a dollop of whipped cream to balance the rich sweetness. Fresh berries or a tangy berry compote make wonderful complementary sides that brighten each bite.
Creative Ways to Present
Cut the blondies into bite-sized squares and layer them on a dessert platter with alternating layers of fresh fruit, nuts, or even a salted caramel sauce drizzle. For a party, serve skewers of blondie cubes paired with marshmallows and fruit for a fun, shareable treat.
Make Ahead and Storage
Storing Leftovers
Store leftover blondies in an airtight container at room temperature for up to 3 days to keep them moist and chewy. You can also refrigerate for up to 5 days; just bring them back to room temperature before serving.
Freezing
These blondies freeze beautifully. Wrap individual portions tightly in plastic wrap and place them in a freezer-safe bag. They will stay fresh for up to 3 months, making them a handy treat anytime you need a quick sweet fix.
Reheating
To enjoy thawed blondies, warm them briefly in the microwave for 10 to 15 seconds. This restores their soft, melty texture and revives those luscious gooey centers like fresh from the oven.
FAQs
Can I substitute peanut butter for Biscoff cookie butter?
While peanut butter will change the flavor profile, you can substitute it in a pinch. Keep in mind, you’ll lose that unique spiced caramel taste that makes the Biscoff Blondies Recipe so special.
What’s the best way to crush Biscoff cookies?
Place the cookies in a sealed plastic bag and use a rolling pin to gently smash them into coarse crumbs. This maintains some texture and contrast in the blondies without turning them into powder.
Can I use light brown sugar instead of dark brown sugar?
Yes, light brown sugar works well and will produce a mildly sweet and moist blondie, though dark brown sugar adds a slightly richer molasses flavor.
How can I make the blondies more gooey?
To maximize gooeyness, underbake them slightly by checking at the 25-minute mark. Also, using fresh eggs and butter with a good fat content helps keep moistness locked in.
Are white chocolate chips necessary?
They’re not absolutely necessary but provide a luxurious creaminess that complements the Biscoff flavor spectacularly. You can omit or swap with milk chocolate chips depending on preference.
