Step‑by‑Step Instructions for Biscoff Blondies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven heats, grab a 9×9-inch baking pan, and either grease it thoroughly with butter or line it with parchment paper. This ensures that your delectable Biscoff Blondies will come out easily after baking, ready to be sliced into perfect squares.
Step 2: Melt the Butters
In a saucepan over low heat, combine the unsalted butter and Biscoff cookie butter. Stir the mixture constantly until it melts into a smooth and velvety consistency, which should take about 3 to 5 minutes. Keep a close eye on it to avoid boiling; you want a beautifully melted blend that infuses the blondies with rich flavor.
Step 3: Incorporate Brown Sugar
Once your butter mixture has cooled slightly, about 5 minutes, whisk in the brown sugar until fully combined and smooth. The mixture should take on a glossy appearance, indicating that the sugar has dissolved well. This step is crucial for achieving that irresistible chewy texture in your Biscoff Blondies.
Step 4: Add Eggs and Vanilla
Next, add the large eggs one at a time, whisking thoroughly after each addition until the batter is cohesive and well-combined. Stir in the pure vanilla extract at this stage; it enhances the overall flavor. The batter should be shiny and smooth, with no lumps remaining.
Step 5: Combine the Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking powder, and salt. Gradually fold this dry mixture into the wet ingredients using a spatula, mixing just until you see no dry flour. Be careful not to overmix, as this can make your Biscoff Blondies dense instead of perfectly chewy.
Step 6: Fold in Chocolates and Cookies
Gently stir in the white chocolate chips and crushed Biscoff cookies, ensuring an even distribution throughout the batter. The combination of melted chocolate and crunchy cookie bits will create delightful pockets of flavor in your blondies.
Step 7: Transfer to the Pan
Pour the batter into the prepared baking pan, spreading it evenly using a spatula to reach all corners. This step is important for even baking, so make sure the surface is level before placing it in the oven. Your Biscoff Blondies are now ready to be baked!
Step 8: Bake to Perfection
Bake the blondies in the preheated oven for about 25 to 30 minutes. After 25 minutes, check for doneness by inserting a toothpick into the center; it should come out clean or with a few moist crumbs. The edges should be golden brown, signaling that your Biscoff Blondies are ready.
Step 9: Cool and Slice
Once baked, remove the blondies from the oven and let them cool in the pan for about 10 minutes. This resting time will help them set up nicely. Afterward, transfer them to a wire rack to cool completely before slicing into squares. Patience here ensures the perfect chewy texture!

Biscoff Blondies Recipe FAQs
How do I choose the right ripeness of Biscoff cookies?
Absolutely! When selecting Biscoff cookies, look for those that are fresh and free from dark spots or cracks. They should be firm yet not overly hard; this helps them blend well into your blondies, providing that delightful crunch.
What’s the best way to store Biscoff Blondies?
To keep your blondies at their best, store them in an airtight container at room temperature for about 3-4 days. I recommend placing a piece of parchment paper between layers to help maintain their moisture and prevent sticking. This simple tip really enhances their chewiness!

When you’re ready to enjoy one, simply thaw them in the fridge or microwave them for about 10-15 seconds!
Why did my blondies turn out dense?
Very often, dense blondies are the result of overmixing the batter. It’s crucial to mix just until combined when adding the dry ingredients to the wet mixture; overmixing can create a tough texture rather than the soft chewiness you want. Moreover, ensure your baking powder is fresh for optimal lift!
Are Biscoff Blondies suitable for people with allergies?
Biscoff Blondies contain common allergens like eggs and gluten from the flour, so they may not be suitable for individuals with allergies to these ingredients. However, you can easily customize this recipe! For a gluten-free version, substitute the all-purpose flour with a 1:1 gluten-free flour blend, and you can explore egg substitutes like applesauce or flax eggs for a dairy-free option.
Can I personalize my Biscoff Blondies with mix-ins?
The more the merrier! Feel free to add your personal touch by including chopped nuts like walnuts or pecans, caramel chips, or different types of chocolate chips. Just make sure to maintain the overall balance of wet and dry ingredients when adding more to ensure your blondies stay chewy and delicious.
