Biscoff Blondies Ingredients
For the Blondie Base
- Unsalted Butter – Provides richness and moisture; if using salted butter, reduce additional salt.
- Biscoff Cookie Butter – The star ingredient that gives these blondies their signature flavor; substitute with speculoos spread or nut butter for variations.
- Brown Sugar – Adds moisture and chewiness; can be replaced with white sugar, but the flavor and texture will change.
- Large Eggs – Binds ingredients together; make sure they’re at room temperature for better incorporation.
- Vanilla Extract – Enhances the flavor profile; using homemade vanilla can add a unique touch.
For the Dry Ingredients
- All-Purpose Flour – Provides the structure necessary for blondies; sifting avoids lumps, and consider gluten-free flour for a gluten-free option.
- Baking Powder – Acts as a leavening agent to keep the blondies light; ensure it’s fresh for effective rising.
- Salt – Balances sweetness; feel free to omit this if using salted butter.
For the Mix-Ins
- White Chocolate Chips – Adds creamy sweetness and contrasts beautifully with the Biscoff flavor; milk chocolate or caramel chips make great substitutes.
- Crushed Biscoff Cookies – Enhances the Biscoff experience with delightful crunchy bits; reduce for less crunch or mix with nuts if desired.
Step‑by‑Step Instructions for Biscoff Blondies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, prepare a 9×9-inch baking pan by greasing it with butter or lining it with parchment paper for easy removal. This ensures your Biscoff Blondies bake evenly and come out perfectly golden brown.
Step 2: Melt the Butters
In a medium saucepan, melt the unsalted butter and Biscoff cookie butter over low heat, stirring gently until the mixture is smooth and combined. This process should take about 3 to 5 minutes. Once melted, remove the saucepan from the heat and allow the mixture to cool slightly before proceeding to the next step.
Step 3: Incorporate the Sugars
Whisk in the brown sugar until fully combined with the butter mixture, creating a thick, cohesive base. Continue mixing until the texture is smooth, which should take about 1 to 2 minutes. This step enhances the sweetness and moisture in your Biscoff Blondies, giving them that rich chewiness everyone loves.
Step 4: Add Eggs and Vanilla
Add the large eggs one at a time, whisking well after each addition to ensure thorough incorporation. Follow this with the vanilla extract, blending until everything is well combined. This will add a comforting aroma and depth of flavor to your Biscoff Blondies, making them even more irresistible!
Step 5: Mix Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking powder, and salt. This helps to eliminate lumps and ensures an even distribution of the leavening agent. Gradually fold this dry mixture into your wet ingredients until just combined; being careful not to overmix, as this will keep your blondies soft and chewy.
Step 6: Fold in the Goodies
Gently fold in the white chocolate chips and crushed Biscoff cookies until they are evenly distributed throughout the batter. This step adds a delightful crunch and sweetness that beautifully complements the chewy texture of the Biscoff Blondies, ensuring a satisfying bite in every square.
Step 7: Prepare for Baking
Pour the blondie batter into your prepared baking pan, using a spatula to spread it evenly across the bottom. Make sure to smooth the top for an even bake. At this point, you can visually assess the batter’s consistency—thick and luscious, ready to transform into your sweet delight.
Step 8: Bake to Perfection
Slide the pan into the preheated oven and bake for 25 to 30 minutes. Keep an eye on them; the blondies are done when the edges are set, and a toothpick inserted comes out with a few moist crumbs attached. This gooey texture is what makes Biscoff Blondies so decadent!
Step 9: Cool Before Serving
Once baked, remove the pan from the oven and let the blondies cool in the pan for about 10 minutes. Afterward, gently transfer them to a wire rack to cool completely. This cooling time allows the blondies to firm up before you cut them into squares, ensuring perfect portions for sharing.

How to Store and Freeze Biscoff Blondies
Room Temperature: Store in an airtight container at room temperature for up to 3-4 days to maintain their softness and chewiness.
Fridge: If you prefer, refrigerate the blondies in an airtight container for up to one week, though this may change their texture slightly.
Freezer: For longer storage, freeze Biscoff Blondies wrapped in wax paper and placed in a freezer-safe bag for up to 2-3 months.
Reheating: To enjoy your blondies warm, simply thaw them at room temperature and reheat in the microwave for about 10-15 seconds, restoring that delightful gooey texture!
