The magic of this Biscoff Blondie Bars Recipe lies in its straightforward, pantry-friendly ingredients that each play a special role. From the fragrant spices adding warmth, to the Biscoff cookies contributing crunch and caramel character, every item helps build layers of flavor and texture that make these bars truly unforgettable.

1 ½ cup all-purpose flour: The base that gives structure to your blondies, ensuring a tender crumb.
1 ¾ teaspoon table salt (or fine sea salt): Enhances flavor and balances sweetness perfectly.
¾ teaspoon ground cinnamon: Infuses the batter with cozy warmth that complements the Biscoff spread.
¼ teaspoon ground nutmeg: Adds a subtle nutty, spicy depth to the flavor profile.
¼ teaspoon ground cloves: Lends a slightly floral and intense spice note, rounding out the spices beautifully.
8 Biscoff cookies (roughly chopped): Mixed into the batter for delightful crunchy surprises in every bar.
1 ¼ cups brown sugar (dark or light; packed): Brings deep caramel sweetness while keeping the blondies moist.
½ cup oil (any neutral oil like canola): Keeps the bars tender and chewy without overpowering the flavors.
2 eggs (room temperature): Bind everything together and provide richness.
1 tablespoon vanilla paste: Adds a rich, creamy vanilla flavor boost that amplifies the sweetness.
½ cup Biscoff spread (warmed): Drizzled on top for extra indulgence and that signature cookie flavor.
6 Biscoff cookies (roughly chopped): Sprinkled on top to give a crunch-topped finish that’s impossible to resist.

How to Make Biscoff Blondie Bars Recipe

Step 1: Preheat Oven and Prep Pan

Start by preheating your oven to 350°F (177°C). Grab an 8×8-inch metal baking pan, spray it lightly with cooking spray, and line it with parchment paper. This step ensures your blondie bars release easily after baking, saving you any sticky situations!

Step 2: Mix Wet Ingredients

In a large mixing bowl, add the packed brown sugar and use your hands or a spatula to break up any lumps. Then add the oil, eggs, and vanilla paste. Whisk everything together until silky and smooth. This silky wet mixture will help create your blondie’s tender, chewy texture.

Step 3: Combine Dry Ingredients

To your wet mixture, add the all-purpose flour, salt, cinnamon, nutmeg, cloves, and the chopped Biscoff cookies. Stir gently until no dry flour spots remain, but be careful not to over-mix, which can make your bars dense.

Step 4: Add Batter to Pan and Top

Pour the batter into your prepared baking pan, spreading it evenly with a spatula. Next, drizzle the warmed Biscoff spread all over the surface. Finally, sprinkle the remaining chopped Biscoff cookies on top to create a crispy, caramelized topping after baking.

Step 5: Bake Until Golden and Set

Place the pan in the oven and bake for 35 to 40 minutes. You’ll know the blondies are ready when a toothpick inserted in the center comes out mostly clean with just a few moist crumbs attached. This ensures gooeyness without under-baking.

Step 6: Cool Completely Before Slicing

Allow the bars to cool completely in the pan for about one hour. Patience here is key; the blondies firm up as they cool, transitioning from a cake-like texture when warm to the perfectly chewy texture we all love once fully set.

Step 7: Cut and Enjoy!

Lift the entire block out of the pan using the parchment paper edges. Slice into 16 squares and prepare yourself for an utterly delicious Biscoff Blondie Bars Recipe experience that everyone will rave about!

Garnishes

To elevate these bars, try dusting them lightly with powdered sugar or a drizzle of melted white chocolate. A sprinkle of crushed Biscoff cookies on top right before serving adds a visually stunning crunch and amps up the cookie flavor.

Side Dishes

These bars pair beautifully with a scoop of vanilla ice cream or a dollop of whipped cream to balance their rich sweetness. For a cozy twist, serve alongside a hot cup of coffee or chai tea that complements the warm spices perfectly.

Creative Ways to Present

Cut the bars into mini squares and serve on a pretty platter for parties, or stack a few with a thin layer of creamy peanut butter between for a delightful sandwich treat. You could also wrap individual bars in parchment for grab-and-go snacks that make sweet gifts.

Make Ahead and Storage

Storing Leftovers

Store your Biscoff Blondie Bars in an airtight container at room temperature for up to four days. They keep their chewy texture wonderfully, making them perfect for week-long sweet cravings.

Freezing

To freeze, cut the bars into squares and place them in a single layer on a baking sheet. Freeze for a couple of hours, then transfer to a freezer-safe bag or container. They can be frozen for up to three months without losing that delightful flavor and texture.

Reheating

When ready to enjoy, thaw bars at room temperature or microwave for 15 to 20 seconds for that freshly-baked warmth. Just a note, heating them slightly brings back that soft, gooey quality that’s simply irresistible.

FAQs

Can I use a different spread if I don’t have Biscoff?

If Biscoff spread is unavailable, you can substitute with cookie butter or even peanut butter for a unique twist. The flavor will be different but still delicious and creamy with similar texture benefits.

Are these bars gluten-free?

Unfortunately, this Biscoff Blondie Bars Recipe calls for all-purpose flour, so it’s not gluten-free as is. However, you can experiment with gluten-free flour blends to create a suitable version, though texture may vary slightly.

How do I know when the blondies are perfectly baked?

The best test is the toothpick method: insert a toothpick into the center, and if it comes out mostly clean with a few moist crumbs clinging, the bars are done. This ensures a balance between cakey and chewy without drying them out.

Can I double the recipe to make a larger batch?

Yes, doubling the ingredients is no problem! Just use a larger baking pan or two pans. Keep an eye on baking time as it might vary slightly depending on thickness and pan size.

Why do the bars become chewy after cooling?

The bars’ transition from cake-like to chewy happens as they cool and the sugars and fats set. This makes the texture more dense and moist, which is exactly what makes these blondies so addictive!
