Ingredients You’ll Need

These ingredients come together in a way that’s both simple and essential, creating that perfect Biscoff Blondies texture and flavor combination. Each item contributes something special, from the fudgy crumb to the sweet, spicy cookie essence that makes this recipe stand out.

• Unsalted butter (¾ cup or 170g): Provides a rich, creamy base that helps achieve that tender, melt-in-your-mouth texture.
• Biscoff cookie butter spread (½ cup or 140g + 2 Tbsp for drizzling): The star ingredient that brings a distinctive spiced caramel flavor and extra moistness.
• Brown sugar (1 cup or 200g): Adds deep caramel notes and keeps the blondies wonderfully chewy.
• Granulated sugar (½ cup or 100g): Balances the sweetness and helps create a light, crisp top crust.
• Large eggs (2, room temperature): Bind everything together for structure while maintaining tenderness.
• Vanilla extract (1 teaspoon): Enhances all the flavors and contributes a lovely aromatic depth.
• All-purpose flour (2 cups or 240g): The backbone of the blondies, giving just the right amount of sturdiness without heaviness.
• Baking powder (1¼ teaspoons): Provides a gentle lift so the bars are soft but not cakey.
• Salt (½ teaspoon): Balances the sweetness and intensifies the other flavors.
• Cinnamon (¼ teaspoon): Adds a cozy warmth that complements the Biscoff cookies wonderfully.
• White chocolate chips (⅔ cup or 130g): Melt into creamy pockets of sweetness throughout the blondies.
• Biscoff cookies (6-8, crushed): Provide a crunchy textured topping that contrasts beautifully with the soft base.

How to Make Biscoff Blondies

Step 1: Prepare Your Pan and Oven

Begin by preheating your oven to 350°F. Lightly grease a 9” x 9” square pan and line it with parchment paper, leaving an overhang on all sides to help lift the blondies out easily once baked. This step is crucial for easy removal and clean edges.

Step 2: Combine the Butter and Sugars

Melt the unsalted butter and let it cool slightly, then pour it into a large mixing bowl along with the Biscoff cookie butter spread, brown sugar, and granulated sugar. Whisk these ingredients thoroughly until the sugars dissolve and the mixture is uniformly smooth—this is the base of your luscious blondies.

Step 3: Mix in Eggs and Vanilla

Add the two eggs and vanilla extract into the bowl, mixing for about 30 seconds until the batter is well combined and shiny. The eggs help bind everything while the vanilla deepens the flavor profile of the blondies.

Step 4: Incorporate Dry Ingredients and Chocolate Chips

Next, sift together the flour, baking powder, salt, and cinnamon. Gently fold these dry ingredients into the wet mixture with a spatula, stirring just until a few streaks of flour remain—avoid overmixing to keep the blondies tender. Then, fold in the white chocolate chips carefully, distributing them evenly.

Step 5: Bake with Biscoff Cookie Topping

Pour the batter into your prepared pan, gently spreading it out with an offset spatula to create an even surface. Sprinkle the crushed Biscoff cookies over the top for that signature crunch. Bake for 30 to 35 minutes until the edges are golden brown and a toothpick inserted in the center comes out with just a few moist crumbs. This indicates the perfect gooey center.

Step 6: Drizzle and Cool

Once baked, let the blondies cool completely in the pan. Melt the reserved 2 tablespoons of cookie butter spread and drizzle it over the top for an extra glossy, flavorful finish. Using the parchment paper overhang, lift the blondies out and cut into 16 equal squares.

How to Serve Biscoff Blondies

Garnishes

For a finishing touch, sprinkle a little extra crushed Biscoff cookie or some white chocolate shavings on top of the drizzled blondies. A small dollop of whipped cream or a light dusting of cinnamon powder can add a touch of elegance and extra warmth to each bite.

Side Dishes

These Biscoff Blondies pair gorgeously with a scoop of vanilla ice cream for an indulgent dessert experience or alongside a hot cup of coffee or chai tea, which complements the spiced cookie flavors perfectly at any time of day.

Creative Ways to Present

Try stacking the blondies into a small tower on a pretty plate and decorate with edible flowers or a drizzle of caramel sauce to impress guests. You can also serve individual squares in mini cupcake liners for easy grab-and-go treats at parties or gatherings.

Make Ahead and Storage

Storing Leftovers

Keep leftover Biscoff Blondies fresh by storing them in an airtight container at room temperature for up to 3 days. This helps maintain their perfect balance of chewy and crispy textures without drying out.

Freezing

To freeze, cut the blondies into squares and place them in a single layer on a baking sheet until frozen solid. Then transfer them to a freezer-safe container or bag. They can be frozen for up to 3 months, making them a convenient treat to enjoy any time.

Reheating

For freshly baked warmth, reheat frozen or refrigerated blondies by microwaving each square for 15-20 seconds or placing them in a low oven (about 300°F) for 5-7 minutes. This revives that gooey, just-baked feel we all love.

FAQs

What makes Biscoff Blondies different from regular blondies?

The inclusion of Biscoff cookie butter spread and crushed Biscoff cookies imparts a unique spiced caramel flavor and an irresistible crunch that you won’t get with traditional blondies.

Can I substitute white chocolate chips with another type?

Absolutely! You can swap white chocolate chips for milk or dark chocolate chips, or even chopped nuts like pecans for added texture and flavor.

Do I need to use room temperature eggs?

Room temperature eggs blend more evenly into the batter which helps create a smooth, consistent texture, but if needed, cold eggs will still work—just mix a bit longer.

Can this recipe be made gluten-free?

Yes, simply replace the all-purpose flour with a gluten-free all-purpose baking blend, ensuring it contains xanthan gum for structure.

How can I tell when the blondies are done baking?

You want the edges to be a golden brown and firm while the center still has a few moist crumbs clinging to a toothpick. Avoid overbaking to keep the blondies soft and gooey.
