If you love the warm caramelized flavor of Biscoff cookies, these Biscoff Blondies are about to become a favorite. They’re soft in the center, slightly chewy around the edges, and packed with that unmistakable spiced cookie-butter flavor.
What makes these blondies especially tempting is the combination of Biscoff spread, crushed Biscoff cookies, and creamy white chocolate. Every bite gives you a soft, buttery texture with little bursts of cookie flavor.
They’re easy enough for a weekend baking project but special enough for holidays, parties, bake sales, or an afternoon treat with coffee.
For the best texture, resist the temptation to overbake them. The center should look just set with a slight softness when they come out of the oven. This helps the blondies stay wonderfully chewy as they cool.

What Makes Homemade Better?
Homemade Biscoff blondies give you control over the texture and flavor. You can make them softer in the center, add extra Biscoff spread on top, or finish them with crushed cookies for an extra-special presentation.
The biggest advantage is freshness. Freshly baked blondies have wonderfully soft edges, a chewy middle, and a warm buttery aroma that packaged desserts simply cannot recreate.
You can also adjust the toppings to suit your taste. Add more white chocolate for sweetness, swirl extra Biscoff spread through the top, or sprinkle crushed cookies over the finished blondies for more crunch.
Ingredients You’ll Need
- Biscoff spread – The star ingredient that gives the blondies their rich caramelized cookie-butter flavor.
- Biscoff cookies – Crush some into crumbs for the batter and save a few pieces for decorating the top.
- Unsalted butter – Adds richness and helps create that soft, chewy blondie texture.
- Brown sugar – Brings moisture and a deeper caramel flavor that works beautifully with Biscoff.
- Granulated sugar – Adds sweetness while helping create lightly crisp edges.
- Eggs – Help bind the ingredients together and give the blondies structure.
- All-purpose flour – Provides the structure without making the blondies too heavy.
- Baking powder – Gives the blondies just enough lift while keeping them dense and chewy.
- Salt – Balances the sweetness and makes the buttery Biscoff flavor stand out.
- White chocolate chips or chopped white chocolate – Add creamy pockets of sweetness throughout the blondies.
Step-By-Step Direction
Step 1: Prepare the Baking Pan
Line your baking pan with parchment paper, leaving some paper hanging over the sides. This makes it much easier to lift the cooled blondies out later.
Step 2: Melt the Butter
Melt the butter gently until smooth. Allow it to cool slightly rather than adding it piping hot to the other ingredients.
Step 3: Add the Biscoff Spread
Stir the Biscoff spread into the melted butter until the mixture becomes smooth and creamy.
This is where the signature Biscoff aroma really starts to develop.
Step 4: Mix the Sugars and Eggs
Combine the sugars and eggs until the mixture is smooth and well blended.
You don’t need to whip it excessively. The goal is a cohesive mixture that will give the blondies a rich texture.
Step 5: Combine the Wet Mixtures
Slowly incorporate the buttery Biscoff mixture into the egg and sugar mixture. Stir until everything is evenly combined.
The batter should look glossy and smell strongly of caramelized Biscoff.
Step 6: Add the Dry Ingredients
Add the flour, baking powder, and salt. Fold gently until you no longer see dry flour.
Avoid overmixing at this stage because too much mixing can make blondies less tender.
Step 7: Fold in the Biscoff Cookies and White Chocolate
Add crushed Biscoff cookies and white chocolate pieces. Fold just enough to distribute them throughout the batter.
Save a little of each for decorating the top if you want an extra-pretty finish.
Step 8: Spread the Batter
Transfer the batter to the prepared pan and spread it evenly from corner to corner.
The batter will be thick, so a spatula works especially well for smoothing the surface.
Step 9: Bake Until Soft and Just Set
Bake until the edges look set and lightly golden while the center still has a little softness.
Don’t wait for the middle to become completely firm in the oven. The blondies will continue setting as they cool.
Step 10: Cool Completely
Let the blondies cool in the pan before slicing. For especially clean slices, chill them briefly after they have cooled.
This step is important because slicing too early can cause the soft center to fall apart.
Step 11: Add the Finishing Touches
Spread a thin layer of softened Biscoff spread over the top if desired. Finish with crushed Biscoff cookies or a whole cookie on individual pieces.
Serving Suggestions
- With coffee – Serve a soft blondie alongside your morning or afternoon coffee for a cozy sweet treat.
- With vanilla ice cream – Add a warm blondie underneath a scoop of vanilla ice cream for an easy dessert.
- With extra Biscoff spread – Warm the spread slightly and drizzle it over the top for an extra-rich finish.
- On a dessert platter – Cut the blondies into small squares and arrange them with cookies, brownies, and other bite-sized desserts.
- For holiday gatherings – Decorate the tops with crushed Biscoff cookies to make them look extra festive.
- With whipped cream – Add a small spoonful of lightly sweetened whipped cream for a softer, creamier dessert.
Tips for the Best Results
- Don’t Overbake the Blondies: The center should still look slightly soft when you remove the pan from the oven. Overbaking is one of the easiest ways to lose that signature chewy texture.
- Let Them Cool Before Cutting: Freshly baked blondies are delicate and continue setting as they cool. Waiting makes them easier to slice and gives you cleaner, more attractive squares.
- Don’t Overmix the Batter: Once the flour is added, mix only until everything is combined. Overmixing can develop too much gluten and make the blondies tougher.
- Use Softened Biscoff Spread for Topping: If you’re adding Biscoff spread to the top, gently warm it until easily spreadable. This creates a smooth finish without tearing the blondie surface.
- Save Some Cookies for the Top: A sprinkle of crushed Biscoff cookies adds texture and makes the finished blondies instantly recognizable. It also gives your dessert a bakery-style appearance.
Storage Tips
Refrigerator
Store completely cooled Biscoff blondies in an airtight container. Place parchment paper between layers if you’re stacking them.
They should keep well in the refrigerator for several days, although the texture may become firmer when chilled.
Let them sit at room temperature for a little while before serving for a softer bite.
Freezer
For longer storage, wrap individual blondie squares tightly and place them in a freezer-safe container or bag.
Freeze them without delicate toppings when possible. Add fresh Biscoff spread or cookie crumbs after thawing for the best appearance.
Reheating
For a soft, freshly baked texture, warm an individual blondie briefly in the microwave.
Be careful not to overheat it because the Biscoff spread and white chocolate can become very hot. A short warming time is usually enough to make the center soft again.
Final Thoughts
These Biscoff Blondies – Soft and Chewy are everything you want in an easy homemade dessert: buttery, chewy, rich, and filled with the warm caramelized flavor of Biscoff cookies.
The combination of creamy Biscoff spread, crunchy cookie crumbs, and sweet white chocolate makes every bite feel a little more special than an ordinary blondie.
Whether you’re baking them for a weekend treat, a holiday dessert table, or simply because you have a jar of Biscoff spread waiting in the pantry, this is a recipe worth saving.
For the best results, remember the three biggest tips: don’t overmix, don’t overbake, and let the blondies cool completely before slicing.
