What Are Biscoff Blondies?
Biscoff Blondies are a delightful twist on the classic blondie. A traditional blondie is like a brownie but without the cocoa, relying on vanilla and brown sugar for its rich, caramel-like flavor. Our version takes this buttery base and infuses it with a generous amount of Biscoff cookie butter, creating a dessert bar with notes of cinnamon, nutmeg, and caramelized sugar. They are simple, elegant, and irresistibly delicious.
Key Ingredients for Perfect Biscoff Blondies
The magic of these blondies comes from a few simple, high-quality ingredients. Here’s what you’ll need and why it matters.
Biscoff Spread & Cookies
This is the hero ingredient. Creamy Biscoff spread is mixed into the batter for flavor and moisture, while crushed Biscoff cookies can be added for texture. We also add a final swirl of melted spread on top for that signature look.
Melted Butter
Using melted butter instead of creamed butter is a key secret to achieving a chewy, dense texture rather than a cakey one. It coats the flour, limiting gluten development.
Brown Sugar
We use light brown sugar for its molasses content, which adds moisture and a rich, caramel-like depth that complements the cookie butter perfectly.
Flour, Cornstarch, and Salt
A standard all-purpose flour works best. We add a touch of cornstarch to make the blondies extra tender and a pinch of salt to balance the sweetness.
Eggs & Vanilla Extract
Two large eggs provide structure and richness. A good quality vanilla extract enhances all the other flavors in the recipe.
White Chocolate Chips
Creamy white chocolate chips are the perfect pairing for the spiced Biscoff flavor, adding pockets of sweetness throughout the blondies. If you love white chocolate, you should also check out our Blueberry Butter Swim Biscuits (coming soon).
How to Make Biscoff Blondies (Step-by-Step)
This easy, one-bowl recipe is as simple as it gets. Follow these steps for flawless Biscoff Blondies.
- Prep Your Pan: Preheat your oven to 350°F (175°C). Grease an 8×8 inch baking pan and line it with parchment paper, leaving an overhang on the sides to act as handles.
- Melt the Butter: In a large microwave-safe bowl, melt the unsalted butter.
- Mix Wet Ingredients: Whisk the brown sugar into the melted butter until fully combined. Add the eggs and vanilla extract and whisk vigorously until the mixture is glossy and smooth. Stir in the creamy Biscoff spread until incorporated.
- Add Dry Ingredients: Add the all-purpose flour, cornstarch, and salt to the wet ingredients. Fold with a spatula until just combined—be careful not to overmix.
- Fold in Chocolate: Gently fold in the white chocolate chips.
- Assemble and Bake: Pour the batter into your prepared pan and spread it into an even layer. In a small bowl, melt the remaining Biscoff spread in the microwave for 15-20 seconds. Drizzle it over the batter and use a knife to create beautiful swirls.
- Bake to Perfection: Bake for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with moist crumbs attached.
- Cool Completely: This is the hardest part! Let the blondies cool completely in the pan before lifting them out with the parchment paper handles and slicing. This ensures clean cuts and a perfect fudgy texture.
Baker’s Tips for the Chewiest Blondies
Want to guarantee blondie perfection? Keep these expert tips in mind.
- Do Not Overmix: Overmixing the batter after adding the flour will develop too much gluten, resulting in a tough, cakey texture. Mix only until you no longer see streaks of flour.
- Don’t Overbake: The key to a fudgy center is to pull the blondies from the oven when they are slightly underbaked. The residual heat will continue to cook them as they cool.
- Let Them Cool: We can’t stress this enough. A full cooling period allows the blondies to set, developing that perfectly dense and chewy texture. Cutting them while warm will result in a gooey mess.
- Measure Flour Correctly: For the best results, weigh your flour with a kitchen scale. If you don’t have one, use the “spoon and level” method: spoon the flour into your measuring cup and level it off with a knife. This prevents a dry, dense blondie.

Storing Your Blondies
These Biscoff Blondies store beautifully, making them a great make-ahead dessert. Store them in an airtight container at room temperature for up to 4 days for maximum freshness. You can also freeze them for up to 3 months. To freeze, slice the blondies and wrap each one individually in plastic wrap before placing them in a freezer-safe bag.
Frequently Asked Questions
Yes, these are a great make-ahead dessert. They stay fresh and chewy in an airtight container at room temperature for up to 4 days. Their flavor even deepens by the second day!
Absolutely! If you enjoy a bit of texture, crunchy Biscoff spread works wonderfully in this recipe. It will add little bits of cookie throughout the blondies.
While the blondies will still be delicious without it, cornstarch is a secret weapon for an extra tender and soft texture. It inhibits some gluten formation, which keeps the blondies from becoming tough.
The edges should be set and a light golden brown. A toothpick inserted into the very center should come out with moist, fudgy crumbs, but not wet batter. Remember, they will continue to set as they cool.
The secret to chewy blondies lies in using melted butter (not creamed) and a high ratio of brown sugar. Also, be very careful not to overbake them; pulling them from the oven when the center is still slightly gooey is key.
