Biscoff Blondies Ingredients
• Bake your heart out with these must-have ingredients!
For the Batter
- Unsalted Butter – Adds richness and moisture; if you’re out, you can use salted butter but reduce any added salt.
- Biscoff Cookie Butter – Provides that signature spiced flavor; feel free to swap with other speculoos spreads, peanut butter, or almond butter, keeping in mind the flavor will adjust.
- Brown Sugar – This gives sweetness and depth, ensuring a deliciously chewy texture.
- Large Eggs – They bind the ingredients together nicely; room temperature eggs work best for smooth incorporation.
- Vanilla Extract – Enhances all the flavors in your blondies; using pure vanilla extract is recommended for a richer taste.
- All-Purpose Flour – The main structure component; be careful not to overmix to keep that melt-in-your-mouth quality.
- Baking Powder – Acts as a leavening agent to help your blondies rise beautifully.
- Salt – Balances the sweetness perfectly; adjust if using salted butter.
- White Chocolate Chips – Adds a touch of sweetness and creamy goodness; semi-sweet or dark chocolate can be used if preferred.
- Crushed Biscoff Cookies – These provide a delightful crunchy texture and flavor in every bite, elevating your Biscoff blondies to new heights!
Step‑by‑Step Instructions for Biscoff Blondies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C) and greasing a 9×9-inch baking pan or lining it with parchment paper for easy removal. This initial step is crucial as it ensures that your Biscoff blondies will rise beautifully while baking. Having everything ready will help streamline the process as you move through the recipe.
Step 2: Melt the Butters
In a medium saucepan over low heat, melt the unsalted butter and Biscoff cookie butter together, stirring gently until the mixture is smooth and well combined, typically taking about 3-5 minutes. Keep an eye on it to prevent burning, as the scent of the warm butters will start to create an irresistible aroma in your kitchen!
Step 3: Mix in the Sugars
Allow the melted mixture to cool slightly for about 5 minutes before whisking in the brown sugar until fully combined. This step helps to maintain the moisture of the blondies while providing that chewy texture. The mixture will start to thicken, indicating that it’s ready for the next ingredients.
Step 4: Incorporate the Eggs and Vanilla
Next, add the large eggs one at a time, whisking vigorously after each addition until fully incorporated into the batter. Follow this by mixing in the vanilla extract until it blends seamlessly. The batter should be shiny and luscious, a perfect base for your Biscoff blondies.
Step 5: Combine Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking powder, and salt. This step ensures there are no lumps and that the leavening agent is evenly distributed. Sifting creates a lighter blender, which will help keep your blondies soft and chewy.
Step 6: Merge Wet and Dry Ingredients
Gradually fold the dry ingredients into the wet mixture using a spatula, mixing just until combined. Be gentle to avoid overmixing, as you want to keep the texture of the Biscoff blondies soft and delicious. It should be thick but moist, making it easily scoopable.
Step 7: Add Final Mix-ins
Now, gently fold in the white chocolate chips and crushed Biscoff cookies, ensuring they are evenly distributed throughout the batter. This adds delightful bursts of sweetness and a crunchy texture that complements the chewy base perfectly, enhancing the overall flavor of your blondies.
Step 8: Pour and Smooth
Pour the batter into the prepared baking pan, making sure to spread it evenly with the spatula. Smooth the top for a nice finish; this will help your Biscoff blondies rise uniformly and create a beautiful golden crust as they bake.
Step 9: Bake to Perfection
Carefully place the pan in the preheated oven and bake for 25-30 minutes. You’ll know they are done when the edges are lightly golden, and a toothpick inserted into the center comes out clean or with a few crumbs—this is a sign of a perfect blondie texture.
Step 10: Cool and Cut
Once baked, remove the pan from the oven and allow the Biscoff blondies to cool for about 10 minutes in the pan. Then, transfer them to a cooling rack to cool completely. This cooling period allows the flavors to meld beautifully, and the blondies will set as they cool, making them easier to cut into squares.

How to Store and Freeze Biscoff Blondies
Room Temperature: Store your Biscoff blondies in an airtight container at room temperature for up to 3-4 days. Keeping them sealed ensures they stay soft and chewy, just as they should be!
Fridge: For extended freshness, you can refrigerate your blondies in an airtight container for up to a week. Just note that refrigeration may affect their chewy texture slightly.
Freezer: If you wish to save some for later, individually wrap the blondies in plastic wrap, then place them in a freezer bag. They will stay fresh for up to 2-3 months! Simply thaw at room temperature or warm them in the microwave for a few seconds when you’re ready to indulge.
Reheating: To enjoy your refrigerated or frozen Biscoff blondies, reheat in the microwave for about 10-15 seconds until warm. This will help restore their delightful softness, making them feel freshly baked each time!
