What You’ll Need
This recipe relies on the magic of melting white chocolate directly into warm butter to create a fudgy, dense crumb. You will need salted butter, high-quality white chocolate chips, and plenty of Biscoff cookies and spread. The combination of granulated and brown sugar ensures a perfect chew and a rich, golden color.
Ingredient Notes
- Salted Butter – Provides a savory richness that perfectly balances the sweetness of the white chocolate and sugars.
- White Chocolate Chips – These serve a dual purpose: half are melted into the batter for texture, while the other half remain whole for creamy pockets of flavor.
- Biscoff Spread – This is slightly melted so it can be swirled into the batter, providing concentrated pockets of spiced cookie butter flavor.
- Biscoff Cookies – These iconic Belgian speculoos cookies are crushed and folded into the batter and sprinkled on top for a delightful crunch.
- Eggs – Ensure these are at room temperature to help them incorporate smoothly into the butter and sugar mixture.
Add-ins and Substitutions
- Nuts – For extra texture, you can fold in 1/2 cup of chopped pecans or macadamia nuts during the final step.
- Sea Salt – A light sprinkle of flaky sea salt on top of the blondies before baking can further enhance the Biscoff spices.
- Dark Chocolate – If you prefer a less sweet profile, you can swap the whole white chocolate chips for dark or semi-sweet chocolate chips.
How to Make Chewy White Chocolate Biscoff Blondies
1. Prep and Melt Preheat your oven to 350 F and center the rack. Prepare an 8×8 baking pan with parchment paper, spraying it with non-stick cooking spray. In a heat-safe bowl, place 1/2 cup of white chocolate chips. In a small saucepan, heat the butter over medium until completely melted. Pour the hot butter over the chips and let it sit for 10 minutes.
2. Create the Batter Stir the butter and white chocolate until fully incorporated and smooth. In a large bowl, whisk this mixture with the granulated and brown sugars until light and fluffy. Add the eggs and whisk until fully incorporated.
3. Fold and Assemble Gently fold in the flour until the batter just begins to come together. Before it is fully mixed, fold in the remaining 1/2 cup of white chocolate chips and 5 of the crushed Biscoff cookies. Pour the batter into your prepared pan and spread it out evenly.
4. Swirl and Bake Drizzle the slightly melted Biscoff spread over the batter and use a butter knife to swirl it through. Sprinkle the remaining 5 crushed Biscoff cookies over the top. Bake for 30 to 40 minutes. You are looking for caramelized edges and a toothpick that comes out clean with just a few crumbs.
5. Cool and Slice Allow the blondies to cool in the pan for 30 minutes. Using a plastic knife will help you get clean cuts as you slice them into 12 equal portions. Let them cool completely before enjoying for the best chewy texture.
Pro Tip: Use binder clips on each side of your baking pan to hold the parchment paper firmly in place. This prevents the paper from folding into your batter as you spread it, ensuring perfectly clean edges on your blondies.
Recipe Tips
- The 10-Minute Wait – Do not rush the white chocolate melting process. Allowing the hot butter to sit on the chips for a full 10 minutes ensures they melt completely without seizing.
- Don’t Overmix – When adding the flour, fold it in gently. Overmixing can lead to a cake-like texture rather than the dense, fudgy chew typical of a great blondie.
- Plastic Knife Trick – Cutting the blondies with a plastic knife while they are still slightly warm prevents the fudgy center from sticking to the blade, giving you professional-looking slices.
FAQs
Can I use a different size pan? This recipe is optimized for an 8×8 pan. If you use a 9×9 pan, the blondies will be thinner and will require a shorter baking time.
How do I store these? Store these blondies in an airtight container at room temperature for up to 4 days, or in the refrigerator for up to a week if you prefer them extra cold and chewy.
What is Biscoff spread? Biscoff spread is a creamy, spreadable version of the Biscoff cookies. It is often found in the peanut butter aisle and is sometimes labeled as “speculoos” or “cookie butter.”
Serving Suggestions
- Ice Cream – Serve a warm blondie with a scoop of vanilla bean or salted caramel ice cream for a truly decadent dessert.
- Coffee Pairing – The spiced cinnamon notes of these blondies make them the perfect companion to a hot cup of coffee or an espresso.
- Dessert Board – Include these on a dessert platter alongside fresh berries to balance the richness.
Make This Recipe in Advance
These blondies are actually easier to slice and develop a deeper flavor if made a day in advance. Once they have cooled completely, wrap the pan in plastic wrap and store at room temperature overnight. Slice them the next morning for the perfect texture.
