Biscoff Blondies

Save this recipe on:

Golden, gooey, and layered with deep caramel spice, Biscoff Blondies are everything a dessert lover dreams of. These bars are chewy in the center, crisp at the edges, and swirled with creamy cookie butter and chunks of white chocolate that melt right into the mix. Each bite delivers that unmistakable Biscoff flavor—a blend of cinnamon, caramel, and buttery bliss.

Perfect for bake sales, cozy afternoons, or gifting something sweet, these blondies come together easily with pantry staples and a jar of Biscoff spread. They’re the kind of treat that stops conversations with a single bite and has everyone asking for the recipe.

What Kind of Cookie Butter Should I Use?

For the richest flavor, use smooth Biscoff spread. It blends seamlessly into the batter and offers a bold punch of caramel spice. Crunchy Biscoff spread can be used if you prefer a little extra texture, but the smooth version gives these blondies their signature, gooey texture. Always go for the name-brand Lotus Biscoff if you want that iconic cookie flavor.

Ingredients for the Biscoff Blondies

Brown sugar: Adds depth and chewiness to the bars. Light brown sugar keeps it balanced; dark brown sugar intensifies the molasses note.

Unsalted butter: Provides a rich base and helps achieve that soft, tender crumb.

Biscoff spread: The star of the show! Brings caramelized cookie flavor throughout the blondies.

White chocolate chips: Add creamy pockets that pair beautifully with the spiced notes.

All-purpose flour: The structural base that holds the blondies together.

Eggs: Bind the ingredients and create that chewy, fudgy texture.

Vanilla extract: Enhances the overall flavor and rounds out the sweetness.

Salt: Just a pinch to balance the richness and sweetness.

How To Make the Biscoff Blondies

Step 1: Prepare Your Baking Pan

Preheat the oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper. This makes removal easier and keeps the blondies from sticking.

Step 2: Melt and Mix

In a saucepan or microwave-safe bowl, melt the butter until just liquified. Stir in the brown sugar and Biscoff spread until smooth and glossy. Let this cool slightly before adding eggs to avoid scrambling.

Step 3: Add Eggs and Vanilla

Whisk in the eggs and vanilla extract until fully incorporated. The batter should look thick and cohesive.

Step 4: Dry Ingredients In

Fold in the flour and salt, mixing just until you no longer see streaks of flour. Over-mixing will make the blondies cakey, so stop as soon as the flour is absorbed.

Step 5: Fold in White Chocolate

Gently stir in the white chocolate chips, reserving a few to sprinkle on top before baking.

Step 6: Bake and Cool

Spread the batter evenly in your prepared pan and top with remaining chocolate chips. Bake for 25–30 minutes or until the edges are golden and a toothpick comes out with a few moist crumbs. Let cool before slicing into squares.
